Commitments, Contingencies and Guarantees

(a) Aircraft, Engine and Other Purchase Commitments

Under all of our aircraft and engine purchase agreements, our total future commitments as of December 31, 2023 are expected to be as follows (approximately, in millions):


	2024		2025		2026		2027		2028		2029 and Thereafter		Total
Payments for aircraft and engine commitments (1)	$	2,410	$	3,725	$	3,580	$	1,118	$	829	$	645	$	12,307

(1)These amounts are net of purchase deposits currently held by the manufacturers. Our purchase deposits held by all manufacturers totaled $760 million and $613 million as of December 31, 2023 and 2022, respectively.

Due to uncertainty surrounding the timing of delivery of certain aircraft, the amounts in the table represent our most current estimate based on contractual delivery schedules adjusted for updates and revisions to such schedules communicated to management by the applicable equipment manufacturer. However, the actual delivery schedule may differ, potentially materially, based on various potential factors including production delays by the manufacturer and regulatory concerns.

Additionally, the amounts in the table exclude five Boeing 787 Family aircraft scheduled to be delivered in 2024, for which we have obtained committed lease financing. See Note 5 for information regarding this operating lease commitment.

Additionally, we have other purchase commitments primarily related to aircraft fuel, flight equipment maintenance and information technology support as follows (approximately): $4.7 billion in 2024, $2.0 billion in 2025, $1.4 billion in 2026, $150 million in 2027, $124 million in 2028 and $843 million in 2029 and thereafter. These amounts exclude obligations under certain fuel offtake agreements or other agreements for which the timing of the related expenditure is uncertain, or which are subject to material contingencies, such as the construction of a production facility.

(b) Capacity Purchase Agreements with Third-Party Regional Carriers

American has capacity purchase agreements with third-party regional carriers. The capacity purchase agreements provide that all revenues, including passenger, in-flight, ancillary, mail and freight revenues, go to American. American controls marketing, scheduling, ticketing, pricing and seat inventories. In return, American agrees to pay predetermined fees to these airlines for operating an agreed-upon number of aircraft, without regard to the number of passengers on board. In addition, these agreements provide that American either reimburses or pays 100% of certain variable costs, such as airport landing fees, fuel and passenger liability insurance.

As of December 31, 2023, American’s capacity purchase agreements with third-party regional carriers had expiration dates ranging from 2024 to 2032, with rights of American to extend the respective terms of certain agreements.

As of December 31, 2023, American’s minimum obligations under its capacity purchase agreements with third-party regional carriers are expected to be as follows (approximately, in millions):


	2024		2025		2026		2027		2028		2029 and Thereafter		Total
Minimum obligations under capacity purchase agreements with third-party regional carriers (1)	$	2,038	$	1,992	$	1,702	$	1,473	$	693	$	1,332	$	9,230

(1)Represents minimum payments under capacity purchase agreements with third-party regional carriers. These commitments are estimates of costs based on assumed minimum levels of flying under the capacity purchase agreements and American’s actual payments could differ materially. Rental payments under operating leases for certain aircraft flown under these capacity purchase agreements are reflected in the operating lease commitments in Note 5.

Los Angeles International Airport (LAX)

From time to time, airports engage in construction projects, often substantial, that result in new or improved facilities that are ultimately funded through increases in the rent and other occupancy costs payable by airlines operating at the airport. Unlike this construction and funding model, we are managing a project at LAX where we have legal title to the assets during construction. In 2018, we executed a lease agreement with Los Angeles World Airports (LAWA), which owns and operates LAX, in connection with a $1.6 billion modernization project related to LAX Terminals 4 and 5. Construction, which started in October 2018 and is expected to be completed in 2028, will occur in a phased approach. The modernization project will include a unified departure hall to the entranceway of Terminals 4 and 5, reconfigured ticket counter and check-in areas with seamless access to security screening areas, 10 new security screening lanes with automated technology in addition to the existing Terminal 5 lanes, and a new Terminal 4 South concourse with more open and upgraded amenities at gate areas. The project will also include renovated break rooms, multi-use meeting rooms and team gathering spaces throughout the terminals to support our team members at LAX.

As each phase is completed and ready for use, the assets will be sold and transferred to LAWA, including the site improvements and other non-proprietary improvements. As we control the assets during construction, they are recognized on our consolidated balance sheets within operating property and equipment until the assets are sold and transferred to LAWA. As of December 31, 2023, we have incurred $862 million in costs relating to the LAX modernization project, of which $283 million were incurred in 2023. Cash paid for non-proprietary improvements are included within other investing activities on our consolidated statements of cash flows. In addition, as of December 31, 2023, we have sold and transferred $346 million of non-proprietary improvements to LAWA, of which $170 million occurred during 2023. For non-proprietary improvements which are not yet ready for use, any cash payments received from LAWA will be reflected as a financial liability included within noncurrent other liabilities on our consolidated balance sheets and reflected as other

financing activities on our consolidated statements of cash flows. As of December 31, 2023, $53 million of cash proceeds received for non-proprietary improvements were not yet ready for use, and therefore have not been sold and transferred back to LAWA.

(d) Off-Balance Sheet Arrangements

Pass-Through Trusts

American currently has 308 owned aircraft and 60 owned spare aircraft engines, which in each case were financed with EETCs issued by pass-through trusts. These trusts are off-balance sheet entities, the primary purpose of which is to finance the acquisition of flight equipment or to permit issuance of debt backed by existing flight equipment. In the case of aircraft EETCs, rather than finance each aircraft separately when such aircraft is purchased, delivered or refinanced, these trusts allow American to raise the financing for a number of aircraft at one time and, if applicable, place such funds in escrow pending a future purchase, delivery or refinancing of the relevant aircraft. Similarly, in the case of the spare engine EETCs, the trusts allow American to use its existing pool of spare engines to raise financing under a single facility. The trusts have also been structured to provide for certain credit enhancements, such as liquidity facilities to cover certain interest payments, that reduce the risks to the purchasers of the trust certificates and, as a result, reduce the cost of aircraft financing to American.

Each trust covers a set number of aircraft or spare engines scheduled to be delivered, financed or refinanced upon the issuance of the EETC or within a specific period of time thereafter. At the time of each covered aircraft or spare engine financing, the relevant trust used the proceeds from the issuance of the EETC (which may have been available at the time of issuance thereof or held in escrow until financing of the applicable aircraft following its delivery) to purchase equipment notes relating to the financed aircraft or engines. The equipment notes are issued, at American’s election, in connection with a mortgage financing of the aircraft or spare engines. The equipment notes are secured by a security interest in the aircraft or engines, as applicable. The pass-through trust certificates are not direct obligations of, nor are they guaranteed by, AAG or American. However, the equipment notes issued to the trusts are direct obligations of American and, in certain instances, have been guaranteed by AAG. As of December 31, 2023, $7.7 billion associated with these mortgage financings is reflected as debt in the accompanying consolidated balance sheet.

Letters of Credit and Other

We provide financial assurance, such as letters of credit and surety bonds, primarily to support projected workers’ compensation obligations and airport commitments. As of December 31, 2023, we had $318 million of letters of credit and surety bonds securing various obligations, of which $94 million is collateralized with our restricted cash. The letters of credit and surety bonds that are subject to expiration will expire on various dates through 2028.

(e) Legal Proceedings

Government Antitrust Action Related to the Northeast Alliance. On September 21, 2021, the United States Department of Justice, joined by Attorneys General from six states and the District of Columbia, filed an antitrust complaint against American and JetBlue Airways Corporation (JetBlue) in the U.S. District Court for the District of Massachusetts alleging that American and JetBlue violated U.S. antitrust law in connection with the previously disclosed Northeast Alliance arrangement (NEA).

On May 19, 2023, the U.S. District Court for the District of Massachusetts issued an order permanently enjoining American and JetBlue from continuing and further implementing the NEA. In June 2023, JetBlue delivered a notice of termination of the NEA, effective July 29, 2023, and the carriers have commenced wind-down activities to accommodate mutual customers. Following written submissions by the parties and a hearing on July 26, 2023, the U.S. District Court for the District of Massachusetts entered a Final Judgment and Order Entering Permanent Injunction on July 28, 2023. The parties are complying with the terms of the Final Judgment and Order Entering Permanent Injunction, including winding down activities related to the NEA. American filed a notice of appeal to the U.S. Court of Appeals for the First Circuit on September 25, 2023, and American’s opening brief was filed on December 6, 2023.

Court for the District of Massachusetts and the U.S. District Court for the Eastern District of New York, respectively. In March 2023, American filed a motion in the U.S. District Court for the District of Massachusetts case asking to transfer the case to the U.S. District Court for the Eastern District of New York and consolidate it with the cases pending in that venue. The U.S. District Court for the District of Massachusetts granted that motion. The remaining cases were consolidated with the other actions in the Eastern District of New York. In June 2023, the private party plaintiffs filed a second amended consolidated complaint, followed by a third amended complaint filed in August 2023. In September 2023, American, together with JetBlue, filed a motion to dismiss the third amended complaint, and that motion remains pending. We believe these lawsuits are without merit and are defending against them vigorously.

General. In addition to the specifically identified legal proceedings, we and our subsidiaries are also engaged in other legal proceedings from time to time. Legal proceedings can be complex and take many months, or even years, to reach resolution, with the final outcome depending on a number of variables, some of which are not within our control. Therefore, although we will vigorously defend ourselves in each of the actions described above and such other legal proceedings, their ultimate resolution and potential financial and other impacts on us are uncertain but could be material.

(f) Guarantees and Indemnifications

We are party to many routine contracts in which we provide general indemnities in the normal course of business to third parties for various risks. We are not able to estimate the potential amount of any liability resulting from the indemnities. These indemnities are discussed in the following paragraphs.

In our aircraft financing agreements, we generally indemnify the financing parties, trustees acting on their behalf and other relevant parties against liabilities (including certain taxes) resulting from the financing, manufacture, design, ownership, operation and maintenance of the aircraft regardless of whether these liabilities (including certain taxes) relate to the negligence of the indemnified parties.

Our loan agreements and certain other financing transactions may obligate us to reimburse the applicable lender for incremental costs due to a change in law that imposes (i) any reserve or special deposit requirement against assets of, deposits with or credit extended by such lender related to the loan, (ii) any tax, duty or other charge with respect to the loan (except standard income tax) or (iii) capital adequacy requirements. In addition, our loan agreements and other financing arrangements typically contain a withholding tax provision that requires us to pay additional amounts to the applicable lender or other financing party, generally if withholding taxes are imposed on such lender or other financing party as a result of a change in the applicable tax law.

In certain transactions, including certain aircraft financing leases and loans, the lessors, lenders and/or other parties have rights to terminate the transaction based on changes in foreign tax law, illegality or certain other events or circumstances. In such a case, we may be required to make a lump sum payment to terminate the relevant transaction.

We have general indemnity clauses in many of our airport and other real estate leases where we as lessee indemnify the lessor (and related parties) against liabilities related to our use of the leased property. Generally, these indemnifications cover liabilities resulting from the negligence of the indemnified parties, but not liabilities resulting from the gross negligence or willful misconduct of the indemnified parties. In addition, we provide environmental indemnities in many of these leases for contamination related to our use of the leased property.

Under certain contracts with third parties, we indemnify the third-party against legal liability arising out of an action by the third-party, or certain other parties. The terms of these contracts vary and the potential exposure under these indemnities cannot be determined. We have liability insurance protecting us from some of the obligations we have undertaken under these indemnities.

American is required to make principal and interest payments for certain special facility revenue bonds issued by municipalities primarily to build or improve airport facilities and purchase equipment, which are leased to American. The payment of principal and interest of certain special facility revenue bonds is guaranteed by AAG. As of December 31, 2023, the remaining lease payments through 2035 guaranteeing the principal and interest on these bonds are $520 million and the current carrying amount of the associated operating lease liability in the accompanying consolidated balance sheet is $321 million.

As of December 31, 2023, AAG had issued guarantees covering approximately $17.5 billion of American’s secured debt (and interest thereon), including the Credit Facilities, 2023 Term Loan Facility, the AAdvantage Financing, certain EETC financings and special facility revenue bonds.

(g) Credit Card Processing Agreements

We have agreements with companies that process customer credit card transactions for the sale of air travel and other services. Our agreements allow these credit card processing companies, under certain conditions, to hold an amount of our cash (referred to as a holdback) equal to all or a portion of advance ticket sales that have been processed by that company, but for which we have not yet provided the air transportation. These holdback requirements can be implemented at the discretion of the credit card processing companies upon the occurrence of specific events, including material adverse changes in our financial condition or the triggering of a liquidity covenant. These credit card processing companies are not currently entitled to maintain any holdbacks. The imposition of holdback requirements would reduce our liquidity.

(h) Labor Contracts

In May 2023, American and the Allied Pilots Association, the union representing our mainline pilots, reached an agreement in principle on a new collective bargaining agreement (CBA), which was ratified in August 2023. This four-year agreement provides wage rate increases, including an initial wage rate increase of 21% effective as of January 1, 2023, quality-of-life benefits and other benefit-related items. The additional compensation for the 2023 period prior to contract ratification as a result of the higher wage rates was recorded within salaries, wages and benefits in the consolidated statements of operations in the second and third quarters of 2023. The agreement also included a provision for a one-time payment upon ratification. In 2023, one-time charges resulting from the ratification of this new agreement were recorded as mainline operating special items, net in the consolidated statement of operations, including the one-time payment of $754 million as well as adjustments to other benefit-related items of $235 million. The one-time payment and the additional compensation were principally paid in 2023, with remaining payments expected to be paid in the first quarter of 2024.

As of December 31, 2023, we employed approximately 132,100 active full-time equivalent (FTE) employees, of which 28,900 were employed by our wholly-owned regional subsidiaries. Of the total active FTE employees, 87% are covered by CBAs with various labor unions and 34% are covered by CBAs that are currently amendable or that will become amendable within one year. In January 2024, mainline passenger service employees represented by the CWA-IBT ratified a new five-year agreement. The CBA covering our flight attendants is now amendable. The CBAs covering certain employee groups at our wholly-owned regional subsidiaries are also amendable.

Commitments, Contingencies and Guarantees

Additionally, American has other purchase commitments primarily related to aircraft fuel, flight equipment maintenance and information technology support as follows (approximately): $4.7 billion in 2024, $2.0 billion in 2025, $1.4 billion in 2026, $150 million in 2027, $124 million in 2028 and $843 million in 2029 and thereafter. These amounts exclude obligations under certain fuel offtake agreements or other agreements for which the timing of the related expenditure is uncertain, or which are subject to material contingencies, such as the construction of a production facility.

(b) Capacity Purchase Agreements with Third-Party Regional Carriers

As of December 31, 2023, American’s minimum obligations under its capacity purchase agreements with third-party regional carriers are expected to be as follows (approximately, in millions):


	2024		2025		2026		2027		2028		2029 and Thereafter		Total
Minimum obligations under capacity purchase agreements with third-party regional carriers (1)	$	2,038	$	1,992	$	1,702	$	1,473	$	693	$	1,332	$	9,230

The project will also include renovated break rooms, multi-use meeting rooms and team gathering spaces throughout the terminals to support American’s team members at LAX.

As each phase is completed and ready for use, the assets will be sold and transferred to LAWA, including the site improvements and other non-proprietary improvements. As American controls the assets during construction, they are recognized on its consolidated balance sheets within operating property and equipment until the assets are sold and transferred to LAWA. As of December 31, 2023, American has incurred $862 million in costs relating to the LAX modernization project, of which $283 million were incurred in 2023. Cash paid for non-proprietary improvements are included within other investing activities on American’s consolidated statements of cash flows. In addition, as of December 31, 2023, American has sold and transferred $346 million of non-proprietary improvements to LAWA, of which $170 million occurred during 2023. For non-proprietary improvements which are not yet ready for use, any cash payments received from LAWA will be reflected as a financial liability included within noncurrent other liabilities on American’s consolidated balance sheets and reflected as other financing activities on its consolidated statements of cash flows. As of December 31, 2023, $53 million of cash proceeds received for non-proprietary improvements were not yet ready for use, and therefore have not been sold and transferred back to LAWA.

(d) Off-Balance Sheet Arrangements

Pass-Through Trusts

of issuance thereof or held in escrow until financing of the applicable aircraft following its delivery) to purchase equipment notes relating to the financed aircraft or engines. The equipment notes are issued, at American’s election, in connection with a mortgage financing of the aircraft or spare engines. The equipment notes are secured by a security interest in the aircraft or engines, as applicable. The pass-through trust certificates are not direct obligations of, nor are they guaranteed by, AAG or American. However, the equipment notes issued to the trusts are direct obligations of American and, in certain instances, have been guaranteed by AAG. As of December 31, 2023, $7.7 billion associated with these mortgage financings is reflected as debt in the accompanying consolidated balance sheet.

Letters of Credit and Other

American provides financial assurance, such as letters of credit and surety bonds, primarily to support projected workers’ compensation obligations and airport commitments. As of December 31, 2023, American had $318 million of letters of credit and surety bonds securing various obligations, of which $94 million is collateralized with American’s restricted cash. The letters of credit and surety bonds that are subject to expiration will expire on various dates through 2028.

(e) Legal Proceedings

Private Party Antitrust Actions Related to the Northeast Alliance. On December 5, 2022 and December 7, 2022, two private party plaintiffs filed putative class action antitrust complaints against American and JetBlue in the U.S. District Court for the Eastern District of New York alleging that American and JetBlue violated U.S. antitrust law in connection with the previously disclosed NEA. These actions were consolidated on January 10, 2023. The private party plaintiffs filed an amended consolidated complaint on February 3, 2023. On February 2, 2023 and February 15, 2023, private party plaintiffs filed two additional putative class action antitrust complaints against American and JetBlue in the U.S. District Court for the District of Massachusetts and the U.S. District Court for the Eastern District of New York, respectively. In March 2023, American filed a motion in the U.S. District Court for the District of Massachusetts case asking to transfer the case to the U.S. District Court for the Eastern District of New York and consolidate it with the cases pending in that venue. The U.S. District Court for the District of Massachusetts granted that motion. The remaining cases were consolidated with the other actions in the Eastern District of New York. In June 2023, the private party plaintiffs filed a second amended consolidated complaint, followed by a third amended complaint filed in August 2023. In September 2023, American, together with JetBlue, filed a motion to dismiss the third amended complaint, and that motion remains pending. American believes these lawsuits are without merit and is defending against them vigorously.

General. In addition to the specifically identified legal proceedings, American and its subsidiaries are also engaged in other legal proceedings from time to time. Legal proceedings can be complex and take many months, or even years, to reach resolution, with the final outcome depending on a number of variables, some of which are not within American’s control. Therefore, although American will vigorously defend itself in each of the actions described above and such other legal proceedings, their ultimate resolution and potential financial and other impacts on American are uncertain but could be material.

(f) Guarantees and Indemnifications

American is a party to many routine contracts in which it provides general indemnities in the normal course of business to third parties for various risks. American is not able to estimate the potential amount of any liability resulting from the indemnities. These indemnities are discussed in the following paragraphs.

In its aircraft financing agreements, American generally indemnifies the financing parties, trustees acting on their behalf and other relevant parties against liabilities (including certain taxes) resulting from the financing, manufacture, design, ownership, operation and maintenance of the aircraft regardless of whether these liabilities (including certain taxes) relate to the negligence of the indemnified parties.

American’s loan agreements and certain other financing transactions may obligate American to reimburse the applicable lender for incremental costs due to a change in law that imposes (i) any reserve or special deposit requirement against assets of, deposits with or credit extended by such lender related to the loan, (ii) any tax, duty or other charge with respect to the loan (except standard income tax) or (iii) capital adequacy requirements. In addition, American’s loan agreements and other financing arrangements typically contain a withholding tax provision that requires American to pay additional amounts to the applicable lender or other financing party, generally if withholding taxes are imposed on such lender or other financing party as a result of a change in the applicable tax law.

In certain transactions, including certain aircraft financing leases and loans, the lessors, lenders and/or other parties have rights to terminate the transaction based on changes in foreign tax law, illegality or certain other events or circumstances. In such a case, American may be required to make a lump sum payment to terminate the relevant transaction.

American has general indemnity clauses in many of its airport and other real estate leases where American as lessee indemnifies the lessor (and related parties) against liabilities related to American’s use of the leased property. Generally, these indemnifications cover liabilities resulting from the negligence of the indemnified parties, but not liabilities resulting from the gross negligence or willful misconduct of the indemnified parties. In addition, American provides environmental indemnities in many of these leases for contamination related to American’s use of the leased property.

Under certain contracts with third parties, American indemnifies the third-party against legal liability arising out of an action by the third-party, or certain other parties. The terms of these contracts vary and the potential exposure under these indemnities cannot be determined. American has liability insurance protecting American from some of the obligations it has undertaken under these indemnities.

American is required to make principal and interest payments for certain special facility revenue bonds issued by municipalities primarily to build or improve airport facilities and purchase equipment, which are leased to American. The payment of principal and interest of certain special facility revenue bonds is guaranteed by American. As of December 31, 2023, the remaining lease payments through 2035 guaranteeing the principal and interest on these bonds are $520 million and the current carrying amount of the associated operating lease liability in the accompanying consolidated balance sheet is $321 million.

As of December 31, 2023, American had issued guarantees covering AAG’s $1.8 billion aggregate principal amount of the PSP1 Promissory Note due April 2030, $1.0 billion aggregate principal amount of the PSP2 Promissory Note due January 2031, $959 million aggregate principal amount of the PSP3 Promissory Note due April 2031, $1.0 billion aggregate principal amount of 6.50% convertible senior notes due July 2025 and $487 million of 3.75% senior notes due March 2025.

(g) Credit Card Processing Agreements

American has agreements with companies that process customer credit card transactions for the sale of air travel and other services. American’s agreements allow these credit card processing companies, under certain conditions, to hold an amount of its cash (referred to as a holdback) equal to all or a portion of advance ticket sales that have been processed by that company, but for which American has not yet provided the air transportation. These holdback requirements can be implemented at the discretion of the credit card processing companies upon the occurrence of specific events, including material adverse changes in American’s financial condition or the triggering of a liquidity covenant. These credit card processing companies are not currently entitled to maintain any holdbacks. The imposition of holdback requirements would reduce American’s liquidity.

(h) Labor Contracts

In May 2023, American and the Allied Pilots Association, the union representing American’s mainline pilots, reached an agreement in principle on a new collective bargaining agreement (CBA), which was ratified in August 2023. This four-year agreement provides wage rate increases, including an initial wage rate increase of 21% effective as of January 1, 2023, quality-of-life benefits and other benefit-related items. The additional compensation for the 2023 period prior to contract ratification as a result of the higher wage rates was recorded within salaries, wages and benefits in the consolidated statements of operations in the second and third quarters of 2023. The agreement also included a provision for a one-time payment upon ratification. In 2023, one-time charges resulting from the ratification of this new agreement were recorded as mainline operating special items, net in the consolidated statement of operations, including the one-time payment of $754 million as well as adjustments to other benefit-related items of $235 million. The one-time payment and the additional compensation were principally paid in 2023, with remaining payments expected to be paid in the first quarter of 2024.

As of December 31, 2023, American employed approximately 103,200 active full-time equivalent (FTE) employees. Of the total active FTE employees, 87% are covered by CBAs with various labor unions and 38% are covered by CBAs that are currently amendable or that will become amendable within one year. In January 2024, mainline passenger service employees represented by the CWA-IBT ratified a new five-year agreement. The CBA covering American’s flight attendants is now amendable.

At December 31, 2023, we had approximately $13.7 billion of gross federal net operating losses (NOLs) and $4.7 billion of other carryforwards available to reduce future federal taxable income, of which $3.4 billion will expire beginning in 2029 if unused and $15.0 billion can be carried forward indefinitely. We also had approximately $5.5 billion of NOL carryforwards to reduce future state taxable income at December 31, 2023, which will expire in taxable years 2023 through 2043 if unused.

Our ability to use our NOLs and other carryforwards depends on the amount of taxable income generated in future periods. We provide a valuation allowance for our deferred tax assets, which include our NOLs, when it is more likely than not that some portion, or all of our deferred tax assets, will not be realized. We consider all available positive and negative evidence and make certain assumptions in evaluating the realizability of our deferred tax assets. Many factors are considered that impact our assessment of future profitability, including conditions which are beyond our control, such as the health of the economy, the availability and price volatility of aircraft fuel and travel demand. We have determined that positive factors outweigh negative factors in the determination of the realizability of our deferred tax assets. There can be no assurance that an additional valuation allowance on our net deferred tax assets will not be required. Such valuation allowance could be material.

Our ability to deduct our NOL carryforwards and to utilize certain other available tax attributes can be substantially constrained under the general annual limitation rules of Section 382 where an “ownership change” has occurred. Substantially all of our remaining federal NOL carryforwards attributable to US Airways Group are subject to limitation under Section 382; however, our ability to utilize such NOL carryforwards is not anticipated to be effectively constrained as a result of such limitation. Similar limitations may apply for state income tax purposes. Our ability to utilize any new NOL carryforwards arising after the ownership changes is not affected by the annual limitation rules imposed by Section 382 unless another ownership change occurs. Under the Section 382 limitation, cumulative stock ownership changes among material stockholders exceeding 50% during a rolling three-year period can potentially limit our future use of NOLs and tax credits.

In 2023, we recorded an income tax provision of $299 million, with an effective rate of approximately 27%, which was substantially non-cash. Substantially all of our income before income taxes is attributable to the United States.

We file our tax returns as prescribed by the tax laws of the jurisdictions in which we operate. Our 2020 through 2022 tax years are still subject to examination by the Internal Revenue Service. Various state and foreign jurisdiction tax years remain open to examination, and we are under examination, in administrative appeals or engaged in tax litigation in certain jurisdictions. We believe that the effect of any assessments will not be material to our consolidated financial statements.

The amount of, and changes to, our uncertain tax positions were not material in any of the years presented. We accrue interest and penalties related to unrecognized tax benefits in interest expense and operating expense, respectively.

At December 31, 2023, American had approximately $13.7 billion of gross federal net operating losses (NOLs) and $3.6 billion of other carryforwards available to reduce future federal taxable income, of which $3.8 billion will expire beginning in 2033 if unused and $13.5 billion can be carried forward indefinitely. American is a member of AAG’s consolidated federal and certain state income tax returns. American also had approximately $5.3 billion of NOL carryforwards to reduce future state taxable income at December 31, 2023, which will expire in taxable years 2023 through 2043 if unused.

American’s ability to use its NOLs and other carryforwards depends on the amount of taxable income generated in future periods. American provides a valuation allowance for its deferred tax assets, which include the NOLs, when it is more likely than not that some portion, or all of its deferred tax assets, will not be realized. American considers all available positive and negative evidence and makes certain assumptions in evaluating the realizability of its deferred tax assets. Many factors are considered that impact American’s assessment of future profitability, including conditions which are beyond its control, such as the health of the economy, the availability and price volatility of aircraft fuel and travel demand. American has determined that positive factors outweigh negative factors in the determination of the realizability of its deferred tax assets. There can be no assurance that an additional valuation allowance on American’s net deferred tax assets will not be required. Such valuation allowance could be material.

American’s ability to deduct its NOL carryforwards and to utilize certain other available tax attributes can be substantially constrained under the general annual limitation rules of Section 382 where an “ownership change” has occurred. Substantially all of American’s remaining federal NOL carryforwards attributable to US Airways Group are subject to limitation under Section 382; however, American’s ability to utilize such NOL carryforwards is not anticipated to be effectively constrained as a result of such limitation. Similar limitations may apply for state income tax purposes. American’s ability to utilize any new NOL carryforwards arising after the ownership changes is not affected by the annual limitation rules imposed by Section 382 unless another ownership change occurs. Under the Section 382 limitation, cumulative stock ownership changes among material stockholders exceeding 50% during a rolling three-year period can potentially limit American’s future use of NOLs and tax credits.

In 2023, American recorded an income tax provision of $394 million, with an effective rate of approximately 25%, which was substantially non-cash. Substantially all of American’s income before income taxes is attributable to the United States.

American files its tax returns as prescribed by the tax laws of the jurisdictions in which it operates. American’s 2020 through 2022 tax years are still subject to examination by the Internal Revenue Service. Various state and foreign jurisdiction tax years remain open to examination, and American is under examination, in administrative appeals or engaged in tax litigation in certain jurisdictions. American believes that the effect of any assessments will not be material to its consolidated financial statements.

The amount of, and changes to, American’s uncertain tax positions were not material in any of the years presented. American accrues interest and penalties related to unrecognized tax benefits in interest expense and operating expense, respectively.

The entire disclosure for income taxes. Disclosures may include net deferred tax liability or asset recognized in an enterprise's statement of financial position, net change during the year in the total valuation allowance, approximate tax effect of each type of temporary difference and carryforward that gives rise to a significant portion of deferred tax liabilities and deferred tax assets, utilization of a tax carryback, and tax uncertainties information.

Basis of Presentation and Summary of Significant Accounting Policies

(a) Basis of Presentation

American Airlines Group Inc. (we, us, our and similar terms, or AAG), a Delaware corporation, is a holding company whose primary business activity is the operation of a major network air carrier, providing scheduled air transportation for passengers and cargo through its mainline operating subsidiary, American Airlines, Inc. (American) and its wholly-owned regional airline subsidiaries, Envoy Aviation Group Inc., PSA Airlines, Inc. (PSA) and Piedmont Airlines, Inc. (Piedmont), that operate under the brand American Eagle. All significant intercompany transactions have been eliminated.

The preparation of financial statements in accordance with accounting principles generally accepted in the United States (GAAP) requires management to make certain estimates and assumptions that affect the reported amounts of assets and liabilities, revenues and expenses, and the disclosure of contingent assets and liabilities at the date of the financial statements. Actual results could differ from those estimates. The most significant areas of judgment relate to passenger revenue recognition, the loyalty program, deferred tax assets, as well as pension and retiree medical and other postretirement benefits.

(b) Government Assistance

Payroll Support Programs

During 2020 and 2021, American, Envoy Air Inc. (Envoy), Piedmont and PSA (together with American, Envoy and Piedmont, the Subsidiaries) entered into payroll support program agreements (PSP Agreements) with the U.S. Department of Treasury (Treasury) pursuant to the payroll support program established under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) (PSP1), the payroll support program established under the Subtitle A of Title IV of Division N of the Consolidated Appropriations Act, 2021 (PSP Extension Law) (PSP2) and the payroll support program established under the American Rescue Plan Act of 2021 (ARP) (PSP3). The aggregate amount of financial assistance received was approximately $12.8 billion, and as partial compensation to the U.S. Government for the provision of financial assistance provided under each of these programs, AAG issued promissory notes and warrants to Treasury.

The table below provides a summary of the financial assistance received and the promissory notes and the warrants issued under each program (in millions, except exercise price amounts):


Program	Closing Date	PSP Financial Assistance		Promissory Notes (1)		PSP Warrants		Total		Warrants Issued (Shares) (2)	Exercise Price of Warrants
PSP1	April 20, 2020	$	4,138	$	1,757	$	63	$	5,958	14.0	$	12.51
PSP2	January 15, 2021	2,427		1,030		76		3,533		6.6	15.66
PSP3	April 23, 2021	2,290		959		46		3,295		4.4	21.75
Total		$	8,855	$	3,746	$	185	$	12,786	25.0

(1)See Note 4 for further information on the promissory notes issued.

(2)The payroll support program warrants (PSP Warrants) are subject to certain anti-dilution provisions, do not have any voting rights and are freely transferable, with registration rights. Each warrant expires on the fifth anniversary of the date of issuance, with expiration dates ranging from April 2025 to June 2026, and will be exercisable either through net share settlement or cash, at our option. The warrants were issued solely as compensation to the U.S. Government related to entry into the PSP Agreements. No separate proceeds (apart from the financial assistance described below) were received upon issuance of the warrants or will be received upon exercise thereof.

In connection with the PSP Agreements entered into with Treasury, we were required to comply with the relevant provisions of the CARES Act, the PSP Extension Law, and the ARP, which included the requirement that funds provided pursuant to these programs be used exclusively for the continuation of payment of eligible employee wages, salaries and benefits, the prohibition against involuntary furloughs and reductions in employee pay rates and benefits, the requirement that certain levels of commercial air service be maintained, provisions that prohibited the repurchase of AAG common stock and the payment of common stock dividends as well as provisions that restrict the payment of certain executive compensation. As of December 31, 2023, all of these provisions have expired.

For accounting purposes, the $12.8 billion of aggregate financial assistance received pursuant to the PSP Agreements was allocated to the promissory notes, warrants and other financial assistance (PSP Financial Assistance). The aggregate principal amount of the promissory notes was recorded as unsecured long-term debt and the total fair value of the warrants, estimated using a Black-Scholes option pricing model, was recorded in stockholders’ deficit in the consolidated balance sheets. The remaining amounts were recognized in 2020 and 2021 as a credit to special items, net in the consolidated statements of operations over the period which the continuation of payment of eligible employee wages, salaries and benefits was required.

Treasury Loan Agreement

On September 25, 2020 (the Treasury Loan Closing Date), AAG and American entered into a Loan and Guarantee Agreement (the Treasury Loan Agreement) with Treasury, which provided for a secured term loan facility (the Treasury Term Loan Facility) that permitted American to borrow up to $5.5 billion. Subsequently, on October 21, 2020, AAG and American entered into an amendment to the Treasury Loan Agreement which increased the borrowing amount up to $7.5 billion. In connection with entry into the Treasury Loan Agreement, on the Treasury Loan Closing Date, AAG also entered into a warrant agreement (the Treasury Loan Warrant Agreement) with Treasury.

In September 2020, American borrowed $550 million under the Treasury Term Loan Facility and on March 24, 2021, used a portion of the proceeds from the AAdvantage Financing to prepay in full the $550 million of outstanding loans under the Treasury Term Loan Facility and terminated the Treasury Loan Agreement. Pursuant to the Treasury Loan Agreement, AAG issued to Treasury warrants (Treasury Loan Warrants) to purchase up to an aggregate of approximately 4.4 million shares of AAG common stock (the Treasury Loan Warrant Shares), which expire in September 2025. The exercise price of the Treasury Loan Warrant Shares is $12.51 per share, subject to certain anti-dilution provisions provided for in the Treasury Loan Warrant Agreement. For accounting purposes, the fair value for the Treasury Loan Warrant Shares, estimated using a Black-Scholes option pricing model, was recorded in stockholders' deficit with an offsetting debt discount to the Treasury Term Loan Facility in the consolidated balance sheet. The provisions of the Treasury Loan Warrants are substantially similar to the PSP Warrants.

ASU 2023-07: Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures

This standard improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this update are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. We are currently evaluating how the adoption of this standard will impact our reportable segment disclosures.

ASU 2023-09: Income Taxes (Topic 740) Improvements to Income Tax Disclosures

This standard enhances transparency of income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information, as well as improvements to the effectiveness and comparability of other income tax disclosures. The amendments in this update are effective for annual periods beginning after December 15, 2024, and early adoption is permitted. We are currently evaluating how the adoption of this standard will impact our income tax disclosures.

(d) Investments

Short-term investments primarily include debt securities and are classified as available-for-sale and stated at fair value. Realized gains and losses are recorded as interest income in nonoperating expense, net on our consolidated statements of operations. Unrealized gains and losses are recorded as a component of accumulated other comprehensive loss on our consolidated balance sheets. For investments in an unrealized loss position, we determine whether a credit loss exists by considering information about the collectability of the instrument, current market conditions and reasonable and supportable forecasts of economic conditions. There have been no credit losses.

Equity investments are accounted for under the equity method if we are able to exercise significant influence over an investee. Equity investments for which we do not have significant influence are recorded at fair value or at cost, if fair value is not readily determinable, with adjustments for observable changes in price or impairments (referred to as the measurement alternative). Our share of equity method investees’ financial results and changes in fair value are recorded in nonoperating other income (expense), net on the consolidated statements of operations. See Note 8 for additional information related to our equity investments.

(e) Restricted Cash and Short-term Investments

We have restricted cash and short-term investments related primarily to collateral held to support workers’ compensation obligations and collateral associated with the AAdvantage Financing.

(f) Accounts Receivable, Net

Accounts receivable primarily consist of amounts due from credit card processing companies for tickets sold to individual passengers, amounts due from airline and non-airline business partners, including our co-branded credit card partners and cargo customers. Receivables from ticket sales are short-term, mostly settled within seven days after sale. Receivables from our business partners are typically settled within 30 days. All accounts receivable are reported net of an allowance for credit losses, which was not material as of December 31, 2023 and 2022. We consider past and future financial and qualitative factors, including aging, payment history and other credit monitoring indicators, when establishing the allowance for credit losses.

(g) Aircraft Fuel, Spare Parts and Supplies, Net

Aircraft fuel is recorded on a first-in, first-out basis. Spare parts and supplies are recorded at average costs less an allowance for obsolescence, which is recognized over the weighted average remaining useful life of the related fleet. We also provide an allowance for spare parts and supplies identified as excess or obsolete to reduce the carrying cost to the lower of cost or net realizable value. Aircraft fuel, spare parts and supplies are expensed when used.

(h) Operating Property and Equipment

Operating property and equipment is recorded at cost and depreciated or amortized to residual values over the asset’s estimated useful life or the lease term, whichever is less, using the straight-line method. Residual values for aircraft, engines and related rotable parts are generally 5% to 10% of original cost. Costs of major improvements that enhance the usefulness of the asset are capitalized and depreciated or amortized over the estimated useful life of the asset or the lease term, whichever is less. The estimated useful lives for the principal property and equipment classifications are as follows:


Principal Property and Equipment Classification			Estimated Useful Life
Aircraft, engines and related rotable parts			20 – 30 years
Buildings and improvements			5 – 30 years
Furniture, fixtures and other equipment			3 – 15 years
Capitalized software			5 – 10 years

Total mainline and regional depreciation and amortization expense was $2.3 billion for each of the years ended December 31, 2023, 2022 and 2021.

We assess impairment of operating property and equipment when events and circumstances indicate that the assets may be impaired. An impairment of an asset or group of assets exists only when the sum of the estimated undiscounted cash flows expected to be generated directly by the assets are less than the carrying value of the assets. We group assets principally by fleet-type when estimating future cash flows, which is generally the lowest level for which identifiable cash flows exist. Estimates of future cash flows are based on historical results adjusted to reflect management’s best estimate of future market and operating conditions, including our current fleet plan. If such assets are impaired, the impairment charge recognized is the amount by which the carrying value of the assets exceed their fair value. Fair value reflects management’s best estimate including inputs from published pricing guides and bids from third parties as well as contracted sales agreements when applicable.

(i) Leases

We determine if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (ROU) assets, current operating lease liabilities and noncurrent operating lease liabilities on our consolidated balance sheets. Finance leases are included in property and equipment, current maturities of long-term debt and finance leases and long-term debt and finance leases, net of current maturities, on our consolidated balance sheets.

ROU assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term.

We use our estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. We give consideration to our recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating our incremental borrowing rates.

Our lease term includes options to extend the lease when it is reasonably certain that we will exercise that option. Leases with a term of 12 months or less are not recorded on our consolidated balance sheets.

Under certain of our capacity purchase agreements with third-party regional carriers, we do not own the underlying aircraft. However, since we control the marketing, scheduling, ticketing, pricing and seat inventories of these aircraft and therefore control the asset, the aircraft is deemed to be leased for accounting purposes. For these capacity purchase agreements, we account for the lease and non-lease components separately. The lease component consists of the aircraft and the non-lease components consist of services, such as the crew and maintenance. Where applicable, we allocate the consideration in the capacity purchase agreements to the lease and non-lease components using their estimated relative standalone prices. See Note 11(b) for additional information on our capacity purchase agreements.

For real estate, we account for the lease and non-lease components as a single lease component.

(j) Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are recorded net as noncurrent deferred income taxes.

We provide a valuation allowance for our deferred tax assets when it is more likely than not that some portion, or all of our deferred tax assets, will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. We consider all available positive and negative evidence and make certain assumptions in evaluating the realizability of our deferred tax assets. Many factors are considered that impact our assessment of future profitability, including conditions which are beyond our control, such as the health of the economy, the availability and price volatility of aircraft fuel and travel demand. We have determined that positive factors outweigh negative factors in the determination of the realizability of our deferred tax assets.

(k) Goodwill

Goodwill represents the purchase price in excess of the fair value of the net assets acquired and liabilities assumed in connection with the 2013 merger with US Airways Group, Inc. (US Airways Group). We have one reporting unit. We assess goodwill for impairment annually or more frequently if events or circumstances indicate that the fair value of goodwill may be lower than the carrying value. Our annual assessment date is October 1.

Goodwill is assessed for impairment by initially performing a qualitative assessment. If we determine that it is more likely than not that our goodwill may be impaired, we use a quantitative approach to assess the asset’s fair value and the amount of the impairment, if any. Based upon our annual assessment, there was no goodwill impairment in 2023. The carrying value of our goodwill on our consolidated balance sheets was $4.1 billion as of December 31, 2023 and 2022.

(l) Other Intangibles, Net

Intangible assets consist primarily of certain domestic airport slots and gate leasehold rights, customer relationships, marketing agreements, commercial agreements, international slots and route authorities and tradenames.

Definite-Lived Intangible Assets

Definite-lived intangible assets are originally recorded at their acquired fair values, subsequently amortized over their respective estimated useful lives and are assessed for impairment whenever events and circumstances indicate that the assets may be impaired.

The following table provides information relating to our amortizable intangible assets as of December 31, 2023 and 2022 (in millions):


	December 31,
	2023		2022
Domestic airport slots	$	365	$	365
Customer relationships	300		300
Marketing agreements	105		105
Tradenames	35		35
Airport gate leasehold rights	137		137
Accumulated amortization	(834)		(827)
Total	$	108	$	115

Certain domestic airport slots and airport gate leasehold rights are amortized on a straight-line basis over 25 years. Certain marketing agreements were identified as intangible assets subject to amortization and are amortized on a straight-line basis over approximately 30 years. Customer relationships and tradenames are fully amortized.

We recorded amortization expense related to these intangible assets of $7 million for the year ended December 31, 2023 and $41 million for each of the years ended December 31, 2022 and 2021. We expect to record annual amortization expense for these intangible assets as follows (in millions):


2024	$	7
2025	7
2026	6
2027	6
2028	6
2029 and thereafter	76
Total	$	108

Indefinite-Lived Intangible Assets

Indefinite-lived intangible assets include certain domestic airport slots, international slots and route authorities and our commercial agreement with GOL Linhas Aéreas Inteligentes S.A. (GOL). We assess indefinite-lived intangible assets for impairment annually or more frequently if events or circumstances indicate that the fair values of indefinite-lived intangible assets may be lower than their carrying values. Our annual assessment date is October 1.

Indefinite-lived intangible assets are assessed for impairment by initially performing a qualitative assessment. If we determine that it is more likely than not that our indefinite-lived intangible assets may be impaired, we use a quantitative approach to assess the asset’s fair value and the amount of the impairment, if any. Based upon our annual assessment, there were no indefinite-lived intangible asset impairments in 2023. We had $1.9 billion of indefinite-lived intangible assets on our consolidated balance sheets as of December 31, 2023 and 2022.

(m) Revenue Recognition

Revenue

The following are the significant categories comprising our operating revenues (in millions):


	Year Ended December 31,
	2023		2022		2021
Passenger revenue:
Passenger travel	$	44,914	$	41,425	$	23,896
Loyalty revenue - travel (1)	3,598		3,143		2,167
Total passenger revenue	48,512		44,568		26,063
Cargo	812		1,233		1,314
Other:
Loyalty revenue - marketing services	2,929		2,657		2,166
Other revenue	535		513		339
Total other revenue	3,464		3,170		2,505
Total operating revenues	$	52,788	$	48,971	$	29,882

(1)Loyalty revenue included in passenger revenue is principally comprised of mileage credit redemptions, which were earned from travel or co-branded credit card and other partners. See “Loyalty Revenue” below for further discussion on these mileage credits.

The following is our total passenger revenue by geographic region (in millions):


	Year Ended December 31,
	2023		2022		2021
Domestic	$	34,592	$	32,911	$	21,453
Latin America	6,719		6,150		3,506
Atlantic	6,205		5,070		965
Pacific	996		437		139
Total passenger revenue	$	48,512	$	44,568	$	26,063

We attribute passenger revenue by geographic region based upon the origin and destination of each flight segment.

Passenger Revenue

We recognize all revenues generated from transportation on American and our regional flights operated under the brand name American Eagle, including associated baggage fees and other inflight services, as passenger revenue when transportation is provided. Ticket and other related sales for transportation that has not yet been provided are initially deferred and recorded as air traffic liability on our consolidated balance sheets. The air traffic liability principally represents tickets sold for future travel on American and partner airlines.

The majority of tickets sold are nonrefundable. A small percentage of tickets, some of which are partially used tickets, expire unused. The estimate for tickets expected to expire unused is generally based on an analysis of our historical data and other current applicable factors such as policy changes. We have consistently applied this accounting method to estimate and recognize revenue from unused tickets at the date of travel. This estimate is periodically evaluated based on subsequent activity to validate its accuracy. Any adjustments resulting from periodic evaluations of the estimated air traffic liability are included in passenger revenue during the period in which the evaluations are completed.

Various taxes and fees assessed on the sale of tickets to end customers are collected by us as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority.

Loyalty Revenue

We currently operate the loyalty program, AAdvantage. This program awards mileage credits to passengers who fly on American, any oneworld airline or other partner airlines, or by using the services of other program participants, such as our co-branded credit cards, and certain hotels and car rental companies. Mileage credits can be redeemed for travel on American and other participating partner airlines, as well as non-air travel awards such as hotels and rental cars. For mileage credits earned by AAdvantage program members, we apply the deferred revenue method.

Mileage credits earned through travel

For mileage credits earned through travel, we apply a relative selling price approach whereby the total amount collected from each passenger ticket sale is allocated between the air transportation and the mileage credits earned. The portion of each passenger ticket sale attributable to mileage credits earned is initially deferred and then recognized in passenger revenue when mileage credits are redeemed and transportation is provided. The estimated selling price of mileage credits is determined using an equivalent ticket value approach, which uses historical data, including award redemption patterns by geographic region and class of service, as well as similar cash fares as those used to settle award redemptions. The estimated selling price of mileage credits is adjusted for an estimate of mileage credits that will not be redeemed using a statistical model based on historical redemption patterns to develop an estimate of the likelihood of future redemption.

Mileage credits sold to co-branded credit cards and other partners

We sell mileage credits to participating airline partners and non-airline business partners, including our co-branded credit card partners, under contracts with remaining terms generally from one to six years as of December 31, 2023. Consideration received from the sale of mileage credits is variable and payment terms typically are within 30 days subsequent to the month of mileage sale. Sales of mileage credits to non-airline business partners are comprised of two components, transportation and marketing. We allocate the consideration received from these sales of mileage credits based on the relative selling price of each product or service delivered.

Our most significant mileage credit partner agreements are our co-branded credit card agreements with Citi and Barclaycard US. We identified two revenue elements in these co-branded credit card agreements: the transportation component and the marketing component.

The transportation component represents the estimated selling price of future travel awards and is determined using the same equivalent ticket value approach described above. The portion of each mileage credit sold attributable to transportation is initially deferred and then recognized in passenger revenue when mileage credits are redeemed and transportation is provided.

The marketing component includes the use of intellectual property, including the American brand and access to loyalty program member lists, which is the predominant element in these agreements, as well as advertising and other travel-related benefits. We recognize the marketing component in other revenue in the period of the mileage credit sale following the sales-based royalty method.

For the portion of our outstanding mileage credits that we estimate will not be redeemed, we recognize the associated value proportionally as the remaining mileage credits are redeemed. Our estimates use a statistical model based on historical redemption patterns to develop an estimate of the likelihood of future redemption.

Cargo Revenue

Cargo revenue is recognized when we provide the transportation.

Other Revenue

Other revenue includes revenue associated with our loyalty program, which is comprised principally of the marketing component of mileage credit sales to co-branded credit card and other partners and other marketing related payments. The accounting and recognition for the loyalty program marketing services are discussed above in “Loyalty Revenue.” The remaining amounts included within other revenue relate to airport clubs, other commission revenue, advertising and vacation-related services.

Contract Balances

Our significant contract liabilities are comprised of (1) outstanding loyalty program mileage credits that may be redeemed for future travel and non-air travel awards, reported as loyalty program liability on our consolidated balance sheets and (2) ticket sales for transportation that has not yet been provided, reported as air traffic liability on our consolidated balance sheets.


	December 31,
	2023		2022
	(In millions)
Loyalty program liability	$	9,327	$	9,145
Air traffic liability	6,200		6,745
Total	$	15,527	$	15,890

The balance of the loyalty program liability fluctuates based on seasonal patterns, which impact the volume of mileage credits issued through travel or sold to co-branded credit card and other partners (deferral of revenue) and mileage credits redeemed (recognition of revenue). Changes in loyalty program liability are as follows (in millions):


Balance at December 31, 2022	$	9,145
Deferral of revenue	3,810
Recognition of revenue (1)	(3,628)
Balance at December 31, 2023 (2)	$	9,327

(1)Principally relates to revenue recognized from the redemption of mileage credits for both air and non-air travel awards. Mileage credits are combined in one homogenous pool and are not separately identifiable. As such, the revenue is comprised of mileage credits that were part of the loyalty program deferred revenue balance at the beginning of the period, as well as mileage credits that were issued during the period.

(2)Mileage credits can be redeemed at any time and generally do not expire as long as that AAdvantage member has any type of qualifying activity at least every 24 months or if the AAdvantage member is the primary holder of a co-branded credit card. As of December 31, 2023, our current loyalty program liability was $3.5 billion and represents our current estimate of revenue expected to be recognized in the next 12 months based on historical trends, with the balance reflected in long-term loyalty program liability expected to be recognized as revenue in periods thereafter.

The air traffic liability principally represents tickets sold for future travel on American and partner airlines. The balance in our air traffic liability also fluctuates with seasonal travel patterns. The contract duration of passenger tickets is generally one year. Accordingly, any revenue associated with tickets sold for future travel will be recognized within 12 months. For 2023, $5.3 billion of revenue was recognized in passenger revenue that was included in our air traffic liability at December 31, 2022.

(n) Maintenance, Materials and Repairs

Maintenance and repair costs for owned and leased flight equipment are charged to operating expense as incurred, except costs incurred for maintenance and repair under certain power-by-the-hour maintenance agreements, which are charged to operating expense based on contractual terms when an obligation exists.

(o) Selling Expenses

Selling expenses include credit card fees, commissions, third party distribution channel fees and advertising. Selling expenses associated with passenger revenue are expensed when the transportation or service is provided. Advertising costs are expensed as incurred. Advertising expense was $114 million for the year ended December 31, 2023 and $105 million for each of the years ended December 31, 2022 and 2021.

(p) Share-based Compensation

We account for our share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The majority of our stock awards are time vested restricted stock units, and the fair value of such awards is based on the market price of the underlying shares of AAG common stock on the date of grant. See Note 14 for further discussion of share-based compensation.

(q) Foreign Currency Gains and Losses

Foreign currency gains and losses are recorded as part of other income (expense), net within total nonoperating expense, net on our consolidated statements of operations. For the years ended December 31, 2023, 2022 and 2021, respectively, foreign currency losses were $30 million, $38 million and $4 million.

(r) Other Operating Expenses

Other operating expenses includes costs associated with onboard food and catering, crew travel, ground and cargo handling, passenger accommodation, international navigation fees, aircraft cleaning, airport lounge operations and certain general and administrative expenses.

(s) Regional Expenses

Our regional carriers provide scheduled air transportation under the brand name “American Eagle.” The American Eagle carriers include our wholly-owned regional carriers as well as third-party regional carriers. Our regional carrier arrangements are in the form of capacity purchase agreements with our third-party regional partners and similar arrangements with our wholly-owned regional affiliates. Expenses associated with American Eagle operations are classified as regional expenses on the consolidated statements of operations.

Regional expenses for the years ended December 31, 2023, 2022 and 2021 include $318 million, $321 million and $316 million of depreciation and amortization, respectively, and $7 million, $5 million and $6 million of aircraft rent, respectively.

In 2023, 2022 and 2021, we recognized $636 million, $592 million and $495 million, respectively, of expense under our capacity purchase agreement with Republic Airways Inc. (Republic). We hold a 25% equity interest in Republic Airways Holdings Inc. (Republic Holdings), the parent company of Republic.

American Airlines, Inc. (American) is a Delaware corporation whose primary business activity is the operation of a major network air carrier, providing scheduled air transportation for passengers and cargo. American is the principal wholly-owned subsidiary of American Airlines Group Inc. (AAG), which owns all of American’s outstanding common stock, par value $1.00 per share. All significant intercompany transactions have been eliminated.

(b) Government Assistance

Payroll Support Programs

During 2020 and 2021, American, Envoy Air Inc. (Envoy), Piedmont Airlines, Inc. (Piedmont) and PSA Airlines, Inc. (PSA and together with American, Envoy and Piedmont, the Subsidiaries) entered into payroll support program agreements (PSP Agreements) with the U.S. Department of Treasury (Treasury) pursuant to the payroll support program established under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) (PSP1), the payroll support program established under the Subtitle A of Title IV of Division N of the Consolidated Appropriations Act, 2021 (PSP Extension Law) (PSP2) and the payroll support program established under the American Rescue Plan Act of 2021 (ARP) (PSP3). The aggregate amount of financial assistance received was approximately $12.8 billion, and as partial compensation to the U.S. Government for the provision of financial assistance provided under each of these programs, AAG issued promissory notes and warrants to Treasury.

The table below provides a summary of the financial assistance received and the promissory notes and the warrants issued under each program (in millions, except exercise price amounts):


Program	Closing Date	PSP Financial Assistance		Promissory Notes (1)		PSP Warrants		Total		Warrants Issued (Shares) (2)	Exercise Price of Warrants
PSP1	April 20, 2020	$	4,138	$	1,757	$	63	$	5,958	14.0	$	12.51
PSP2	January 15, 2021	2,427		1,030		76		3,533		6.6	15.66
PSP3	April 23, 2021	2,290		959		46		3,295		4.4	21.75
Total		$	8,855	$	3,746	$	185	$	12,786	25.0

(1)As partial compensation to the U.S. Government for the provision of financial assistance under the PSP Agreements, AAG issued promissory notes to Treasury (PSP1 Promissory Note, PSP2 Promissory Note and PSP3 Promissory Note, collectively the PSP Promissory Notes), in the aggregate principal sum of $3.7 billion which provides for the guarantee of AAG’s obligations under the PSP Promissory Notes by the Subsidiaries.

(2)The payroll support program warrants (PSP Warrants) are subject to certain anti-dilution provisions, do not have any voting rights and are freely transferable, with registration rights. Each warrant expires on the fifth anniversary of the date of issuance, with expiration dates ranging from April 2025 to June 2026, and will be exercisable either through net share settlement or cash, at AAG’s option. The warrants were issued solely as compensation to the U.S. Government related to entry into the PSP Agreements. No separate proceeds (apart from the financial assistance described below) were received upon issuance of the warrants or will be received upon exercise thereof.

In connection with the PSP Agreements entered into with Treasury, AAG and the Subsidiaries were required to comply with the relevant provisions of the CARES Act, the PSP Extension Law, and the ARP, which included the requirement that funds provided pursuant to these programs be used exclusively for the continuation of payment of eligible employee wages, salaries and benefits, the prohibition against involuntary furloughs and reductions in employee pay rates and benefits, the requirement that certain levels of commercial air service be maintained, provisions that prohibited the

repurchase of AAG common stock and the payment of common stock dividends as well as provisions that restrict the payment of certain executive compensation. As of December 31, 2023, all of these provisions have expired.

For accounting purposes, the $12.8 billion of aggregate financial assistance received pursuant to the PSP Agreements was allocated to the promissory notes, warrants and other financial assistance (PSP Financial Assistance). The aggregate principal amount of the promissory notes was recorded as unsecured long-term debt and the total fair value of the warrants, estimated using a Black-Scholes option pricing model, was recorded in stockholders’ deficit in AAG’s consolidated balance sheets. The remaining amounts were recognized in 2020 and 2021 as a credit to special items, net in the consolidated statements of operations over the period which the continuation of payment of eligible employee wages, salaries and benefits was required.

Treasury Loan Agreement

On September 25, 2020 (the Treasury Loan Closing Date), AAG and American entered into a Loan and Guarantee Agreement (the Treasury Loan Agreement) with Treasury, which provided for a secured term loan facility (the Treasury Term Loan Facility) that permitted American to borrow up to $5.5 billion. Subsequently, on October 21, 2020, AAG and American entered into an amendment to the Treasury Loan Agreement which increased the borrowing amount up to $7.5 billion. In connection with AAG’s entry into the Treasury Loan Agreement, on the Treasury Loan Closing Date, AAG also entered into a warrant agreement (the Treasury Loan Warrant Agreement) with Treasury.

In September 2020, American borrowed $550 million under the Treasury Term Loan Facility and on March 24, 2021, used a portion of the proceeds from the AAdvantage Financing to prepay in full the $550 million of outstanding loans under the Treasury Term Loan Facility and terminated the Treasury Loan Agreement. Pursuant to the Treasury Loan Agreement, AAG issued to Treasury warrants (Treasury Loan Warrants) to purchase up to an aggregate of approximately 4.4 million shares of AAG common stock (the Treasury Loan Warrant Shares), which expire in September 2025. The exercise price of the Treasury Loan Warrant Shares is $12.51 per share, subject to certain anti-dilution provisions provided for in the Treasury Loan Warrant Agreement. For accounting purposes, the fair value for the Treasury Loan Warrant Shares, estimated using a Black-Scholes option pricing model, was recorded in stockholders' deficit in AAG’s consolidated balance sheet with an offsetting debt discount to the Treasury Term Loan Facility in American’s consolidated balance sheet. The provisions of the Treasury Loan Warrants are substantially similar to the PSP Warrants.

Accounting Standards Update (ASU) 2023-07: Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures

This standard improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this update are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. American is currently evaluating how the adoption of this standard will impact its reportable segment disclosures.

ASU 2023-09: Income Taxes (Topic 740) Improvements to Income Tax Disclosures

This standard enhances transparency of income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information, as well as improvements to the effectiveness and comparability of other income tax disclosures. The amendments in this update are effective for annual periods beginning after December 15, 2024, and early adoption is permitted. American is currently evaluating how the adoption of this standard will impact its income tax disclosures.

(d) Investments

Short-term investments primarily include debt securities and are classified as available-for-sale and stated at fair value. Realized gains and losses are recorded as interest income in nonoperating expense, net on American’s consolidated statements of operations. Unrealized gains and losses are recorded as a component of accumulated other comprehensive loss on American’s consolidated balance sheets. For investments in an unrealized loss position, American determines whether a credit loss exists by considering information about the collectability of the instrument, current market conditions and reasonable and supportable forecasts of economic conditions. There have been no credit losses.

Equity investments are accounted for under the equity method if American is able to exercise significant influence over an investee. Equity investments for which American does not have significant influence are recorded at fair value or at cost, if fair value is not readily determinable, with adjustments for observable changes in price or impairments (referred to as the measurement alternative). American’s share of equity method investees’ financial results and changes in fair value are recorded in nonoperating other income (expense), net on the consolidated statements of operations. See Note 7 for additional information related to American’s equity investments.

(e) Restricted Cash and Short-term Investments

American has restricted cash and short-term investments related primarily to collateral held to support workers’ compensation obligations and collateral associated with the AAdvantage Financing.

(f) Accounts Receivable, Net

Accounts receivable primarily consist of amounts due from credit card processing companies for tickets sold to individual passengers, amounts due from airline and non-airline business partners, including American’s co-branded credit card partners and cargo customers. Receivables from ticket sales are short-term, mostly settled within seven days after sale. Receivables from American’s business partners are typically settled within 30 days. All accounts receivable are reported net of an allowance for credit losses, which was not material as of December 31, 2023 and 2022. American considers past and future financial and qualitative factors, including aging, payment history and other credit monitoring indicators, when establishing the allowance for credit losses.

(g) Aircraft Fuel, Spare Parts and Supplies, Net

Aircraft fuel is recorded on a first-in, first-out basis. Spare parts and supplies are recorded at average costs less an allowance for obsolescence, which is recognized over the weighted average remaining useful life of the related fleet. American also provides an allowance for spare parts and supplies identified as excess or obsolete to reduce the carrying cost to the lower of cost or net realizable value. Aircraft fuel, spare parts and supplies are expensed when used.

(h) Operating Property and Equipment


Principal Property and Equipment Classification			Estimated Useful Life
Aircraft, engines and related rotable parts			20 – 30 years
Buildings and improvements			5 – 30 years
Furniture, fixtures and other equipment			3 – 15 years
Capitalized software			5 – 10 years

Total mainline and regional depreciation and amortization expense was $2.2 billion for each of the years ended December 31, 2023 and 2022 and $2.3 billion for the year ended December 31, 2021.

American assesses impairment of operating property and equipment when events and circumstances indicate that the assets may be impaired. An impairment of an asset or group of assets exists only when the sum of the estimated undiscounted cash flows expected to be generated directly by the assets are less than the carrying value of the assets. American groups assets principally by fleet-type when estimating future cash flows, which is generally the lowest level for which identifiable cash flows exist. Estimates of future cash flows are based on historical results adjusted to reflect management’s best estimate of future market and operating conditions, including American’s current fleet plan. If such assets are impaired, the impairment charge recognized is the amount by which the carrying value of the assets exceed their fair value. Fair value reflects management’s best estimate including inputs from published pricing guides and bids from third parties as well as contracted sales agreements when applicable.

(i) Leases

American determines if an arrangement is a lease at inception. Operating leases are included in operating lease right-of-use (ROU) assets, current operating lease liabilities and noncurrent operating lease liabilities on American’s consolidated balance sheets. Finance leases are included in property and equipment, current maturities of long-term debt and finance leases and long-term debt and finance leases, net of current maturities, on American’s consolidated balance sheets.

ROU assets represent American’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments arising from the lease. ROU assets and liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term.

American uses its estimated incremental borrowing rate, which is derived from information available at the lease commencement date, in determining the present value of lease payments. American gives consideration to its recent debt issuances as well as publicly available data for instruments with similar characteristics when calculating its incremental borrowing rates.

American’s lease term includes options to extend the lease when it is reasonably certain that it will exercise that option. Leases with a term of 12 months or less are not recorded on its consolidated balance sheets.

Under certain of American’s capacity purchase agreements with third-party regional carriers, American does not own the underlying aircraft. However, since American controls the marketing, scheduling, ticketing, pricing and seat inventories of these aircraft and therefore control the asset, the aircraft is deemed to be leased for accounting purposes. For these capacity purchase agreements, American accounts for the lease and non-lease components separately. The lease component consists of the aircraft and the non-lease components consist of services, such as the crew and maintenance. Where applicable, American allocates the consideration in the capacity purchase agreements to the lease and non-lease components using their estimated relative standalone prices. See Note 10(b) for additional information on its capacity purchase agreements.

For real estate, American accounts for the lease and non-lease components as a single lease component.

(j) Income Taxes

American provides a valuation allowance for its deferred tax assets when it is more likely than not that some portion, or all of its deferred tax assets, will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. American considers all available positive and negative evidence and makes certain assumptions in evaluating the realizability of its deferred tax assets. Many factors are considered that impact American’s assessment of future profitability, including conditions which are beyond its control, such as the health of the economy, the availability and price volatility of aircraft fuel and travel demand. American has determined that positive factors outweigh negative factors in the determination of the realizability of its deferred tax assets.

(k) Goodwill

Goodwill represents the purchase price in excess of the fair value of the net assets acquired and liabilities assumed in connection with the 2013 merger with US Airways Group, Inc. (US Airways Group). American has one reporting unit. American assesses goodwill for impairment annually or more frequently if events or circumstances indicate that the fair value of goodwill may be lower than the carrying value. American’s annual assessment date is October 1.

Goodwill is assessed for impairment by initially performing a qualitative assessment. If American determines that it is more likely than not that its goodwill may be impaired, it uses a quantitative approach to assess the asset’s fair value and the amount of the impairment, if any. Based upon American’s annual assessment, there was no goodwill impairment in 2023. The carrying value of American’s goodwill on its consolidated balance sheets was $4.1 billion as of December 31, 2023 and 2022.

(l) Other Intangibles, Net

Definite-Lived Intangible Assets

The following table provides information relating to American’s amortizable intangible assets as of December 31, 2023 and 2022 (in millions):

Indefinite-Lived Intangible Assets

Indefinite-lived intangible assets include certain domestic airport slots, international slots and route authorities and American’s commercial agreement with GOL Linhas Aéreas Inteligentes S.A. (GOL). American assesses indefinite-lived intangible assets for impairment annually or more frequently if events or circumstances indicate that the fair values of indefinite-lived intangible assets may be lower than their carrying values. American’s annual assessment date is October 1.

Indefinite-lived intangible assets are assessed for impairment by initially performing a qualitative assessment. If American determines that it is more likely than not that its indefinite-lived intangible assets may be impaired, American uses a quantitative approach to assess the asset’s fair value and the amount of the impairment, if any. Based upon American’s annual assessment, there were no indefinite-lived intangible asset impairments in 2023. American had $1.9 billion of indefinite-lived intangible assets on its consolidated balance sheets as of December 31, 2023 and 2022.

Pacific	996		437		139
Total passenger revenue	$	48,512	$	44,568	$	26,063

American attributes passenger revenue by geographic region based upon the origin and destination of each flight segment.

Passenger Revenue

American recognizes all revenues generated from transportation on American and its regional flights operated under the brand name American Eagle, including associated baggage fees and other inflight services, as passenger revenue when transportation is provided. Ticket and other related sales for transportation that has not yet been provided are initially deferred and recorded as air traffic liability on American’s consolidated balance sheets. The air traffic liability principally represents tickets sold for future travel on American and partner airlines.

The majority of tickets sold are nonrefundable. A small percentage of tickets, some of which are partially used tickets, expire unused. The estimate for tickets expected to expire unused is generally based on an analysis of American’s historical data and other current applicable factors such as policy changes. American has consistently applied this accounting method to estimate and recognize revenue from unused tickets at the date of travel. This estimate is periodically evaluated based on subsequent activity to validate its accuracy. Any adjustments resulting from periodic evaluations of the estimated air traffic liability are included in passenger revenue during the period in which the evaluations are completed.

Various taxes and fees assessed on the sale of tickets to end customers are collected by American as an agent and remitted to taxing authorities. These taxes and fees have been presented on a net basis in the accompanying consolidated statements of operations and recorded as a liability until remitted to the appropriate taxing authority.

Loyalty Revenue

American currently operates the loyalty program, AAdvantage. This program awards mileage credits to passengers who fly on American, any oneworld airline or other partner airlines, or by using the services of other program participants, such as American’s co-branded credit cards, and certain hotels and car rental companies. Mileage credits can be redeemed for travel on American and other participating partner airlines, as well as non-air travel awards such as hotels and rental cars. For mileage credits earned by AAdvantage program members, American applies the deferred revenue method.

Mileage credits earned through travel

For mileage credits earned through travel, American applies a relative selling price approach whereby the total amount collected from each passenger ticket sale is allocated between the air transportation and the mileage credits earned. The portion of each passenger ticket sale attributable to mileage credits earned is initially deferred and then recognized in passenger revenue when mileage credits are redeemed and transportation is provided. The estimated selling price of mileage credits is determined using an equivalent ticket value approach, which uses historical data, including award redemption patterns by geographic region and class of service, as well as similar cash fares as those used to settle award redemptions. The estimated selling price of mileage credits is adjusted for an estimate of mileage credits that will not be redeemed using a statistical model based on historical redemption patterns to develop an estimate of the likelihood of future redemption.

Mileage credits sold to co-branded credit cards and other partners

American sells mileage credits to participating airline partners and non-airline business partners, including American’s co-branded credit card partners, under contracts with remaining terms generally from one to six years as of December 31, 2023. Consideration received from the sale of mileage credits is variable and payment terms typically are within 30 days subsequent to the month of mileage sale. Sales of mileage credits to non-airline business partners are comprised of two components, transportation and marketing. American allocates the consideration received from these sales of mileage credits based on the relative selling price of each product or service delivered.

American’s most significant mileage credit partner agreements are its co-branded credit card agreements with Citi and Barclaycard US. American identified two revenue elements in these co-branded credit card agreements: the transportation component and the marketing component.

The marketing component includes the use of intellectual property, including the American brand and access to loyalty program member lists, which is the predominant element in these agreements, as well as advertising and other travel-related benefits. American recognizes the marketing component in other revenue in the period of the mileage credit sale following the sales-based royalty method.

For the portion of American’s outstanding mileage credits that it estimates will not be redeemed, American recognizes the associated value proportionally as the remaining mileage credits are redeemed. American’s estimates use a statistical model based on historical redemption patterns to develop an estimate of the likelihood of future redemption.

Cargo Revenue

Cargo revenue is recognized when American provides the transportation.

Other Revenue

Other revenue includes revenue associated with American’s loyalty program, which is comprised principally of the marketing component of mileage credit sales to co-branded credit card and other partners and other marketing related payments. The accounting and recognition for the loyalty program marketing services are discussed above in “Loyalty Revenue.” The remaining amounts included within other revenue relate to airport clubs, other commission revenue, advertising and vacation-related services.

Contract Balances

American’s significant contract liabilities are comprised of (1) outstanding loyalty program mileage credits that may be redeemed for future travel and non-air travel awards, reported as loyalty program liability on American’s consolidated balance sheets and (2) ticket sales for transportation that has not yet been provided, reported as air traffic liability on American’s consolidated balance sheets.


	December 31,
	2023		2022
	(In millions)
Loyalty program liability	$	9,327	$	9,145
Air traffic liability	6,200		6,745
Total	$	15,527	$	15,890


Balance at December 31, 2022	$	9,145
Deferral of revenue	3,810
Recognition of revenue (1)	(3,628)
Balance at December 31, 2023 (2)	$	9,327

(2)Mileage credits can be redeemed at any time and generally do not expire as long as that AAdvantage member has any type of qualifying activity at least every 24 months or if the AAdvantage member is the primary holder of a co-branded credit card. As of December 31, 2023, American’s current loyalty program liability was $3.5 billion and represents American’s current estimate of revenue expected to be recognized in the next 12 months based on historical trends, with the balance reflected in long-term loyalty program liability expected to be recognized as revenue in periods thereafter.

The air traffic liability principally represents tickets sold for future travel on American and partner airlines. The balance in American’s air traffic liability also fluctuates with seasonal travel patterns. The contract duration of passenger tickets is generally one year. Accordingly, any revenue associated with tickets sold for future travel will be recognized within 12 months. For 2023, $5.3 billion of revenue was recognized in passenger revenue that was included in American’s air traffic liability at December 31, 2022.

American accounts for its share-based compensation expense based on the fair value of the stock award at the time of grant, which is recognized ratably over the vesting period of the stock award. Certain awards have performance conditions that must be achieved prior to vesting and are expensed based on the expected achievement at each reporting period. The majority of American’s stock awards are time vested restricted stock units, and the fair value of such awards is based on the market price of the underlying shares of AAG common stock on the date of grant. See Note 13 for further discussion of share-based compensation.

(q) Foreign Currency Gains and Losses

Foreign currency gains and losses are recorded as part of other income (expense), net within total nonoperating expense, net on American’s consolidated statements of operations. For the years ended December 31, 2023, 2022 and 2021, respectively, foreign currency losses were $30 million, $38 million and $4 million.

Segment Reporting Information [Line Items]
Operating Segments and Related Disclosures	Operating Segments and Related Disclosures We are managed as a single business unit that provides air transportation for passengers and cargo. This allows us to benefit from an integrated revenue pricing and route network that includes American and our wholly-owned and third-party regional carriers that fly under capacity purchase agreements operating as American Eagle. The flight equipment of all these carriers is combined to form one fleet that is deployed through a single route scheduling system. Financial information and annual operational plans and forecasts are prepared and reviewed by the chief operating decision maker at the consolidated level. When making operational decisions, the chief operating decision maker evaluates flight profitability data, which considers aircraft type and route economics, but is indifferent to the results of the individual regional carriers. The objective in making operational decisions is to maximize consolidated financial results, not the individual results of American or American Eagle. See Note 1(m) for our passenger revenue by geographic region. Our tangible assets consist primarily of flight equipment, which are mobile across geographic markets and, therefore, have not been allocated.

Employee Benefit Plans

We sponsor defined benefit and defined contribution pension plans for eligible employees. The defined benefit pension plans provide benefits for participating employees based on years of service and average compensation for a specified period of time before retirement. Effective November 1, 2012, substantially all of our defined benefit pension plans were frozen and we began providing enhanced benefits under our defined contribution pension plans for certain employee groups. We use a December 31 measurement date for all of our defined benefit pension plans. We also provide certain retiree medical and other postretirement benefits, including health care and life insurance benefits, to retired employees.

Assumptions

The following actuarial assumptions were used to determine our benefit obligations and net periodic benefit cost (income) for the periods presented:


	Pension Benefits		Retiree Medical and Other Postretirement Benefits
	2023	2022	2023	2022
Benefit obligations:
Weighted average discount rate	5.2%	5.6%	5.3%	5.7%


	Pension Benefits			Retiree Medical and Other Postretirement Benefits
	2023	2022	2021	2023	2022	2021
Net periodic benefit cost (income):
Weighted average discount rate	5.6%	3.0%	2.7%	5.7%	2.8%	2.4%
Weighted average expected rate of return on plan assets	8.0%	8.0%	8.0%	8.0%	8.0%	8.0%
Weighted average health care cost trend rate assumed for next year (1)	N/A	N/A	N/A	6.5%	5.8%	4.8%

(1)The weighted average health care cost trend rate at December 31, 2023 is assumed to decline gradually to 4.5% by 2033 and remain level thereafter.

As of December 31, 2023, our estimate of the long-term rate of return on plan assets was 8.0% based on the target asset allocation. Expected returns on long duration bonds are based on yields to maturity of the bonds held at year-end. Expected returns on other assets are based on a combination of long-term historical returns, actual returns on plan assets achieved over the last 10 years, current and expected market conditions, and expected value to be generated through active management and securities lending programs.

Minimum Contributions

We are required to make minimum contributions to our defined benefit pension plans under the minimum funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA) and various other laws for U.S. based plans as well as underfunding rules specific to countries where we maintain defined benefit pension plans. Based on current funding assumptions, we have minimum required contributions of $284 million for 2024 including contributions to defined benefit pension plans for our wholly-owned subsidiaries. Our future funding obligations will depend on the performance of our investments held in a trust by the pension plans, interest rates for determining funding targets, the amount of and timing of any supplemental contributions and our actuarial experience.

Benefit Payments

The following benefit payments, which reflect expected future service as appropriate, are expected to be paid (approximately, in millions):


	2024		2025		2026		2027		2028		2029-2033
Pension benefits	$	952	$	977	$	1,002	$	1,023	$	1,036	$	5,265
Retiree medical and other postretirement benefits	138		144		150		150		148		674

Plan Assets

The objectives of our investment policies are to: maintain sufficient income and liquidity to pay retirement benefits; produce a long-term rate of return that meets or exceeds the assumed rate of return for plan assets; limit the volatility of asset performance and funded status; and diversify assets among asset classes and investment managers.

Based on these investment objectives, a long-term strategic asset allocation has been established. This strategic allocation seeks to balance the potential benefit of improving the funded position with the potential risk that the funded position would decline. The current strategic target asset allocation with the corresponding allowed range is as follows:


Asset Class/Sub-Class	Target Allocation		Allowed Range
Equity	61	%	30% - 85%
Public:
U.S. Large	19	%	10% - 40%
U.S. Small/Mid	5	%	0% - 10%
International Large	13	%	5% - 25%
International Small/Mid	3	%	0% - 10%
Emerging Markets	6	%	0% - 15%
Private Equity	15	%	5% - 30%

Fixed Income	39	%	15% - 70%
Public U.S. Fixed Income	30	%	15% - 60%
Private Income	9	%	0% - 20%

Other	—	%	0% - 5%
Cash Equivalents	—	%	0% - 20%

Public equity investments are intended to provide a real return over a full market cycle and, therefore, to contribute to the pension plan’s long-term objective. Public fixed income investments are intended to provide income to the plan and offer the potential for long term capital appreciation. Private investments, such as private equity and private income, are used to provide higher expected returns than public markets over the long-term by assuming reduced levels of liquidity and higher levels of risk. The pension plan’s master trust participates in securities lending programs to generate additional income by loaning plan assets to borrowers on a fully collateralized basis. The pension plan’s master trust will also engage in derivative instruments to equitize residual levels of cash as well as hedge the pension plan’s exposure to interest rates. Such programs are subject to market risk and counterparty risk.

Investments in securities traded on recognized securities exchanges are valued at the last reported sales price on the last business day of the year. Securities traded in the over-the-counter market are valued at the last bid price. Investments in limited partnerships are carried at estimated net asset value (NAV) as determined by and reported by the general partners of the partnerships and represent the proportionate share of the estimated fair value of the underlying assets of the limited partnerships. Mutual funds are valued once daily through a NAV calculation provided at the end of each trade day. Common/collective trusts are valued at NAV based on the fair values of the underlying investments of the trusts as determined by the sponsor of the trusts. No changes in valuation techniques or inputs occurred during the year.

Benefit Plan Assets Measured at Fair Value on a Recurring Basis

The fair value of our pension plan assets at December 31, 2023 and 2022, by asset category, were as follows (in millions) (1):


	December 31, 2023								December 31, 2022
	Level 1		Level 2		Level 3		Total		Level 1		Level 2		Level 3		Total

Total plan assets	$	3,436	$	3,586	$	84	$	12,431	$	3,398	$	3,195	$	75	$	11,884

(1)See Note 7 for a description of the levels within the fair value hierarchy.

(2)Equity investments include domestic and international common stock, preferred stock and mutual funds invested in equity securities.

(3)Fixed income investments include corporate, government and U.S. municipal bonds, as well as mutual funds invested in fixed income securities.

(4)Other primarily includes a short-term investment fund, net receivables and payables of the master trust for dividends, interest and amounts due to or from the sale and purchase of securities and cash and cash equivalents.

(5)Includes investments that were measured at NAV per share (or its equivalent) as a practical expedient that have not been classified in the fair value hierarchy.

(6)Common collective trusts include commingled funds primarily invested in equity securities. For some trusts, requests for withdrawals must meet specific requirements with advance notice of redemption preferred.

(7)Private investments include limited partnerships that invest primarily in domestic private equity and private income opportunities. The pension plan’s master trust does not have the right to redeem its limited partnership investment at its NAV, but rather receives distributions as the underlying assets are liquidated. It is estimated that the underlying assets of these funds will be gradually liquidated over the next 10 years. As of December 31, 2023, the pension plan’s master trust has future funding commitments to these limited partnerships of approximately $1.3 billion, most of which are expected to be called over the next five years.

Changes in fair value measurements of Level 3 investments during the years ended December 31, 2023 and 2022, were as follows (in millions):


	2023		2022
Balance at beginning of year	$	75	$	58
Actual gain (loss) on plan assets:
Relating to assets still held at the reporting date	(9)		1
Purchases	20		29
Sales	(2)		(9)
Transfers out	—		(4)
Balance at end of year	$	84	$	75

Plan assets in the retiree medical and other postretirement benefits plans are primarily Level 2 mutual funds valued by quoted prices on the active market, which is fair value, and represents the NAV of the shares of such funds as of the close of business at the end of the period. NAV is based on the fair market value of the funds’ underlying assets and liabilities at the date of determination.

Defined Contribution and Multiemployer Plans

The costs associated with our defined contribution plans were $1.1 billion, $949 million and $920 million for the years ended December 31, 2023, 2022 and 2021, respectively.

We participate in the International Association of Machinists & Aerospace Workers (IAM) National Pension Fund, Employer Identification No. 51-6031295 and Plan No. 002 (the IAM Pension Fund). Our contributions to the IAM Pension Fund were $52 million, $46 million and $43 million for the years ended December 31, 2023, 2022 and 2021, respectively. The IAM Pension Fund reported $533 million in employers’ contributions for the year ended December 31, 2022, which is the most recent year for which such information is available. For 2022, our contributions represented more than 5% of total contributions to the IAM Pension Fund.

On March 29, 2019, the actuary for the IAM Pension Fund certified that the fund was in “endangered” status despite reporting a funded status of over 80%. Additionally, the IAM Pension Fund’s Board voluntarily elected to enter into “critical” status on April 17, 2019. Upon entry into critical status, the IAM Pension Fund was required by law to adopt a rehabilitation plan aimed at restoring the financial health of the pension plan and did so on April 17, 2019 (the Rehabilitation Plan). Under the Rehabilitation Plan, we were subject to an immaterial contribution surcharge, which ceased to apply June 14, 2019 upon our mandatory adoption of a contribution schedule under the Rehabilitation Plan. The contribution schedule requires 2.5% annual increases to our contribution rate. This contribution schedule will remain in effect through the earlier of December 31, 2031 or the date the IAM Pension Fund emerges from critical status.

Profit Sharing Program

We accrue a percentage of our pre-tax income excluding net special items for our profit sharing program. For the year ended December 31, 2023, we accrued $261 million for this program, which will be distributed to employees in the first quarter of 2024.

Employee Benefit Plans

American sponsors defined benefit and defined contribution pension plans for eligible employees. The defined benefit pension plans provide benefits for participating employees based on years of service and average compensation for a specified period of time before retirement. Effective November 1, 2012, substantially all of American’s defined benefit pension plans were frozen and American began providing enhanced benefits under its defined contribution pension plans for certain employee groups. American uses a December 31 measurement date for all of its defined benefit pension plans. American also provides certain retiree medical and other postretirement benefits, including health care and life insurance benefits, to retired employees.

Assumptions

The following actuarial assumptions were used to determine American’s benefit obligations and net periodic benefit cost (income) for the periods presented:


	Pension Benefits		Retiree Medical and Other Postretirement Benefits
	2023	2022	2023	2022
Benefit obligations:
Weighted average discount rate	5.2%	5.6%	5.3%	5.7%

Weighted average health care cost trend rate assumed for next year (1)	N/A	N/A	N/A	6.5%	5.8%	4.8%

(1)The weighted average health care cost trend rate at December 31, 2023 is assumed to decline gradually to 4.5% by 2033 and remain level thereafter.

As of December 31, 2023, American’s estimate of the long-term rate of return on plan assets was 8.0% based on the target asset allocation. Expected returns on long duration bonds are based on yields to maturity of the bonds held at year-end. Expected returns on other assets are based on a combination of long-term historical returns, actual returns on plan assets achieved over the last 10 years, current and expected market conditions, and expected value to be generated through active management and securities lending programs.

Minimum Contributions

American is required to make minimum contributions to its defined benefit pension plans under the minimum funding requirements of the Employee Retirement Income Security Act of 1974 (ERISA) and various other laws for U.S. based plans as well as underfunding rules specific to countries where American maintains defined benefit pension plans. Based on current funding assumptions, American has minimum required contributions of $280 million for 2024. American’s future funding obligations will depend on the performance of American’s investments held in a trust by the pension plans, interest rates for determining funding targets, the amount of and timing of any supplemental contributions and American’s actuarial experience.

Benefit Payments

The following benefit payments, which reflect expected future service as appropriate, are expected to be paid (approximately, in millions):


	2024		2025		2026		2027		2028		2029-2033

Retiree medical and other postretirement benefits	138		144		150		150		148		674

Plan Assets

The objectives of American’s investment policies are to: maintain sufficient income and liquidity to pay retirement benefits; produce a long-term rate of return that meets or exceeds the assumed rate of return for plan assets; limit the volatility of asset performance and funded status; and diversify assets among asset classes and investment managers.

Additionally, the IAM Pension Fund’s Board voluntarily elected to enter into “critical” status on April 17, 2019. Upon entry into critical status, the IAM Pension Fund was required by law to adopt a rehabilitation plan aimed at restoring the financial health of the pension plan and did so on April 17, 2019 (the Rehabilitation Plan). Under the Rehabilitation Plan, American was subject to an immaterial contribution surcharge, which ceased to apply June 14, 2019 upon American’s mandatory adoption of a contribution schedule under the Rehabilitation Plan. The contribution schedule requires 2.5% annual increases to its contribution rate. This contribution schedule will remain in effect through the earlier of December 31, 2031 or the date the IAM Pension Fund emerges from critical status.

Profit Sharing Program

American accrues a percentage of its pre-tax income excluding net special items for its profit sharing program. For the year ended December 31, 2023, American accrued $261 million for this program, which will be distributed to employees in the first quarter of 2024.

Leases

12 Months Ended

Dec. 31, 2023

We lease certain aircraft and engines, including aircraft under capacity purchase agreements. As of December 31, 2023, we operated 737 leased aircraft, including seven aircraft in temporary storage and 237 aircraft leased under capacity purchase agreements, with remaining terms ranging from less than one year to 10 years.

At each airport where we conduct flight operations, we have agreements, generally with a governmental unit or authority, for the use of passenger, operations and baggage handling space as well as runways and taxiways. These agreements, particularly in the U.S., often contain provisions for periodic adjustments to rates and charges applicable under such agreements. These rates and charges also vary with our level of operations and the operations of the airport. Because of the variable nature of these rates, these leases are not recorded on our consolidated balance sheets as a ROU asset or a lease liability. Additionally, at our hub locations and in certain other cities we serve, we lease administrative offices, catering, cargo, training, maintenance and other facilities.

Fair Value Measurements

Assets Measured at Fair Value on a Recurring Basis

Fair value is defined as the price that would be received from the sale of an asset or paid to transfer a liability (i.e., an exit price) on the measurement date in an orderly transaction between market participants in the principal or most advantageous market for the asset or liability. Accounting standards include disclosure requirements around fair values used for certain financial instruments and establish a fair value hierarchy. The hierarchy prioritizes valuation inputs into three levels based on the extent to which inputs used in measuring fair value are observable in the market. Each fair value measurement is reported in one of three levels:

•Level 1 – Observable inputs such as quoted prices in active markets;

•Level 2 – Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and

•Level 3 – Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions.

When available, we use quoted market prices to determine the fair value of our financial assets. If quoted market prices are not available, we measure fair value using valuation techniques that use, when possible, current market-based or independently-sourced market parameters, such as interest rates and currency rates.

We utilize the market approach to measure the fair value of our financial assets. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets. Our short-term investments, restricted cash and restricted short-term investments classified as Level 2 utilize significant observable inputs, other than quoted prices in active markets, for valuation of these securities. No changes in valuation techniques or inputs occurred during the year ended December 31, 2023.

Assets measured at fair value on a recurring basis are summarized below (in millions):

Fair Value of Debt

The fair value of our long-term debt was estimated using quoted market prices or discounted cash flow analyses based on our current estimated incremental borrowing rates for similar types of borrowing arrangements. If our long-term debt was measured at fair value, it would have been classified as Level 2 except for $3.7 billion as of December 31, 2023 and December 31, 2022, which would have been classified as Level 3 in the fair value hierarchy. The fair value of the Convertible Notes, which would have been classified as Level 2, was $1.1 billion as of December 31, 2023 and December 31, 2022.

The carrying value and estimated fair value of our long-term debt, including current maturities, were as follows (in millions):

In February 2023, American and AAG refinanced approximately $1.8 billion in aggregate principal amount of term loans outstanding under the 2013 Term Loan Facility (the 2013 Term Loan Facility Refinancing) through the combination of (i) the issuance of $750 million in aggregate principal amount of 7.25% senior secured notes due 2028 and (ii) the entry into the Seventh Amendment to the 2013 Credit Agreement, pursuant to which the maturity of $1.0 billion in term loans under the 2013 Term Loan Facility was extended to February 2028 from June 2025. The Seventh Amendment also amended certain other terms of the 2013 Credit Agreement, including the interest rate and amortization schedule for the 2013 Term Loan Facility, the requirements for delivery of appraisals and certain covenants relating to dispositions of collateral. Additionally, the Seventh Amendment transitioned the benchmark interest rate from the London Interbank Offered Rate (LIBOR) to the Secured Overnight Financing Rate (SOFR).

The 2014 Revolving Facility bears interest at the same base rate and applicable margin as the 2013 Revolving Facility, as noted above in “2013 Credit Facilities.” The 2014 Term Loan Facility bears interest at a base rate (subject to a floor of 1.00%) plus an applicable margin of 0.75% or, at American’s option, the SOFR rate for a tenor of one, three or six months, depending on the interest period selected by American, plus the SOFR adjustment applicable to such interest period (with such SOFR rate plus SOFR adjustment being subject to a floor of 0.00%) plus an applicable margin of 1.75%. As of December 31, 2023, the margin elected was 1.75%. Additionally, as a result of the Ninth Amendment, through October 11, 2024, the aggregate commitments under the 2014 Revolving Facility will be $1.6 billion, and thereafter through October 13, 2026, such aggregate commitments will decrease to $1.2 billion.

At December 31, 2023, the if-converted value of the Convertible Notes did not exceed the principal amount.

Each $1,000 principal amount of Convertible Notes is convertible at a rate of 61.7284 shares of our common stock, subject to adjustment as provided in the Convertible Notes Indenture.

(g) Unsecured Senior Notes

3.75% Senior Notes

In February 2020, AAG issued $500 million aggregate principal amount of 3.75% senior notes due 2025 (the 3.75% Senior Notes). The 3.75% Senior Notes bear interest at a rate of 3.75% per annum, payable semiannually in arrears in March and September of each year, which began in September 2020. The 3.75% Senior Notes mature in March 2025.

The 3.75% Senior Notes are senior unsecured obligations of AAG. These Senior Notes are fully and unconditionally guaranteed by American. The indentures for these Senior Notes contain covenants and events of default generally customary for similar financings.

Other Financing Activities

During the year ended December 31, 2023, we repurchased $552 million of secured and unsecured notes in the open market. In connection with the repurchase of these secured and unsecured notes in the open market, American recorded $57 million of cash special charges for premiums paid and $6 million of non-cash special charges to write off unamortized debt issuance costs and debt discounts.

Guarantees

Certain Covenants

Our debt agreements contain customary terms and conditions as well as various affirmative, negative and financial covenants that, among other things, may restrict the ability of us and our subsidiaries to incur additional indebtedness, pay dividends or repurchase stock. Our debt agreements also contain customary change of control provisions, which may require us to repay or redeem such indebtedness upon certain events constituting a change of control under the relevant agreement, in certain cases at a premium. Certain of our debt financing agreements (including our secured notes, term loans, revolving credit facilities and spare engine EETCs) contain loan to value (LTV), collateral coverage or peak debt service coverage ratio covenants and certain agreements require us to appraise the related collateral annually or semiannually. Pursuant to such agreements, if the applicable LTV, collateral coverage or peak debt service coverage ratio exceeds or falls below a specified threshold, as the case may be, we will be required, as applicable, to pledge additional qualifying collateral (which in some cases may include cash or investment securities), withhold additional cash in certain accounts, or pay down such financing, in whole or in part, or the interest rate for the relevant financing will be increased. Additionally, a significant portion of our debt financing agreements contain covenants requiring us to maintain an aggregate of at least $2.0 billion of unrestricted cash and cash equivalents and amounts available to be drawn under revolving credit facilities, and our AAdvantage Financing contains a peak debt service coverage ratio, pursuant to which failure to comply with a certain threshold may result in early repayment, in whole or in part, of the AAdvantage Financing.

Share-based Compensation

12 Months Ended

Dec. 31, 2023

Share-based Compensation Arrangement by Share-based Payment Award [Line Items]

In May 2023, the stockholders of AAG approved the 2023 Incentive Award Plan (the 2023 Plan). The 2023 Plan replaces and supersedes AAG’s 2013 Incentive Award Plan (the 2013 Plan). No further awards will be granted under the 2013 Plan; however, the terms and conditions of the 2013 Plan will continue to govern any outstanding awards granted thereunder. The 2023 Plan provides that an award may be in the form of a stock option, including an incentive stock option and nonqualified stock option, stock appreciation right, restricted stock, restricted stock unit, performance bonus award, performance stock unit, other stock or cash-based award and dividend equivalent to eligible individuals.

The 2023 Plan authorizes the grant of awards for the issuance of 17.2 million shares less any shares granted under the 2013 Plan after March 22, 2023, the date the Board of Directors of AAG approved the 2023 Plan. Any shares underlying awards granted under the 2023 Plan or 2013 Plan that are forfeited, terminate or are settled in cash (in whole or in part) without the delivery of shares will again be available for grant under the 2023 Plan.

For the years ended December 31, 2023, 2022 and 2021, we recorded $102 million, $78 million and $98 million, respectively, of share-based compensation costs principally in salaries, wages and benefits expense on our consolidated statements of operations.

During 2023, 2022 and 2021, we withheld approximately 1.5 million, 1.2 million and 1.0 million shares of AAG common stock, respectively, and paid approximately $23 million, $21 million and $18 million, respectively, in satisfaction of certain tax withholding obligations associated with employee equity awards.

Restricted Stock Unit Awards (RSUs)

We have granted RSUs with service conditions (time vested primarily over three years) and performance conditions. The grant-date fair value of these RSUs is equal to the market price of the underlying shares of AAG common stock on the date of grant. For time vested awards, the expense is recognized on a straight-line basis over the vesting period for the entire award. For awards with performance conditions, the expense is recognized based on the expected achievement at each reporting period. RSUs are classified as equity awards as the vesting results in the issuance of shares of AAG common stock.

RSU award activity for all plans for the years ended December 31, 2023, 2022 and 2021 is as follows:


	Number of Shares	Weighted Average Grant Date Fair Value
	(In thousands)
Outstanding at December 31, 2020	7,882	$	23.66

As of December 31, 2023, there was $127 million of unrecognized compensation cost related to RSUs. These costs are expected to be recognized over a weighted average period of one year. The total fair value of RSUs vested during the years ended December 31, 2023, 2022 and 2021 was $78 million, $70 million and $62 million, respectively.

Recent Accounting Pronouncements

Accounting Standards Update (ASU) 2023-07: Segment Reporting (Topic 280) Improvements to Reportable Segment Disclosures

This standard improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments in this update are effective for fiscal years beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024, and early adoption is permitted. American is currently evaluating how the adoption of this standard will impact its reportable segment disclosures.

ASU 2023-09: Income Taxes (Topic 740) Improvements to Income Tax Disclosures

This standard enhances transparency of income tax information through improvements to income tax disclosures primarily related to the rate reconciliation and income taxes paid information, as well as improvements to the effectiveness and comparability of other income tax disclosures. The amendments in this update are effective for annual periods beginning after December 15, 2024, and early adoption is permitted. American is currently evaluating how the adoption of this standard will impact its income tax disclosures.

Restricted Cash and Short-term Investments

Short-term investments primarily include debt securities and are classified as available-for-sale and stated at fair value. Realized gains and losses are recorded as interest income in nonoperating expense, net on American’s consolidated statements of operations. Unrealized gains and losses are recorded as a component of accumulated other comprehensive loss on American’s consolidated balance sheets. For investments in an unrealized loss position, American determines whether a credit loss exists by considering information about the collectability of the instrument, current market conditions and reasonable and supportable forecasts of economic conditions. There have been no credit losses.

American has restricted cash and short-term investments related primarily to collateral held to support workers’ compensation obligations and collateral associated with the AAdvantage Financing.

Accounts Receivable, Net

Accounts receivable primarily consist of amounts due from credit card processing companies for tickets sold to individual passengers, amounts due from airline and non-airline business partners, including American’s co-branded credit card partners and cargo customers. Receivables from ticket sales are short-term, mostly settled within seven days after sale. Receivables from American’s business partners are typically settled within 30 days. All accounts receivable are reported net of an allowance for credit losses, which was not material as of December 31, 2023 and 2022. American considers past and future financial and qualitative factors, including aging, payment history and other credit monitoring indicators, when establishing the allowance for credit losses.

Aircraft Fuel, Spare Parts and Supplies, Net

Aircraft fuel is recorded on a first-in, first-out basis. Spare parts and supplies are recorded at average costs less an allowance for obsolescence, which is recognized over the weighted average remaining useful life of the related fleet. American also provides an allowance for spare parts and supplies identified as excess or obsolete to reduce the carrying cost to the lower of cost or net realizable value. Aircraft fuel, spare parts and supplies are expensed when used.

Operating Property and Equipment


Principal Property and Equipment Classification			Estimated Useful Life
Aircraft, engines and related rotable parts			20 – 30 years
Buildings and improvements			5 – 30 years
Furniture, fixtures and other equipment			3 – 15 years
Capitalized software			5 – 10 years

Impairment

For real estate, American accounts for the lease and non-lease components as a single lease component.

Maintenance, Materials and Repairs

Goodwill

Goodwill represents the purchase price in excess of the fair value of the net assets acquired and liabilities assumed in connection with the 2013 merger with US Airways Group, Inc. (US Airways Group). American has one reporting unit. American assesses goodwill for impairment annually or more frequently if events or circumstances indicate that the fair value of goodwill may be lower than the carrying value. American’s annual assessment date is October 1.

Other Intangibles, Net

Definite-Lived Intangible Assets

Indefinite-Lived Intangible Assets

Revenue Recognition

American attributes passenger revenue by geographic region based upon the origin and destination of each flight segment.

Passenger Revenue

The majority of tickets sold are nonrefundable. A small percentage of tickets, some of which are partially used tickets, expire unused. The estimate for tickets expected to expire unused is generally based on an analysis of American’s historical data and other current applicable factors such as policy changes. American has consistently applied this accounting method to estimate and recognize revenue from unused tickets at the date of travel. This estimate is periodically evaluated based on subsequent activity to validate its accuracy. Any adjustments resulting from periodic evaluations of the estimated air traffic liability are included in passenger revenue during the period in which the evaluations are completed.

Loyalty Revenue

Mileage credits earned through travel

Mileage credits sold to co-branded credit cards and other partners

The marketing component includes the use of intellectual property, including the American brand and access to loyalty program member lists, which is the predominant element in these agreements, as well as advertising and other travel-related benefits. American recognizes the marketing component in other revenue in the period of the mileage credit sale following the sales-based royalty method.

Cargo Revenue

Cargo revenue is recognized when American provides the transportation.
