New Accounting Pronouncements or Change in Accounting Principle [Line Items]
Basis of Presentation and Recent Accounting Pronouncements	Basis of Presentation and Recent Accounting Pronouncements (a) Basis of Presentation The accompanying unaudited condensed consolidated financial statements of American Airlines Group Inc. (we, us, our and similar terms, or AAG) should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2020. The accompanying unaudited condensed consolidated financial statements include the accounts of AAG and its wholly-owned subsidiaries. AAG’s principal subsidiary is American Airlines, Inc. (American). All significant intercompany transactions have been eliminated. Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited condensed consolidated financial statements for the interim periods presented. 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, impairment of goodwill, impairment of long-lived and intangible assets, the loyalty program, deferred tax assets, as well as pension and retiree medical and other postretirement benefits. Certain prior period amounts have been reclassified to conform to the current year presentation. See Note 10 for further information. (b) Impact of Coronavirus (COVID-19) COVID-19 has been declared a global health pandemic by the World Health Organization. COVID-19 has surfaced in nearly all regions of the world, which has driven the implementation of significant, government-imposed measures to prevent or reduce its spread, including travel restrictions, testing regimes, closing of borders, “stay at home” orders and business closures. As a result, we have experienced an unprecedented decline in the demand for air travel, which has resulted in a material deterioration in our revenues. While global vaccination efforts are underway and demand for air travel has begun to return, the continued impact of COVID-19, including any increases in infection rates and renewed governmental action to slow the spread of COVID-19 such as has occurred throughout Western Europe and Latin America in the first quarter of 2021, cannot be estimated. We have taken aggressive actions to mitigate the effects of the COVID-19 pandemic on our business, including deep capacity reductions, structural changes to our fleet, cost reductions, and steps to preserve cash and improve our overall liquidity position. We remain extremely focused on taking all self-help measures available to manage our business during this unprecedented time, consistent with the terms of the financial assistance we have received from the U.S. Government under the Coronavirus Aid, Relief, and Economic Security Act (CARES Act) and Subtitle A of Title IV of Division N of the Consolidated Appropriations Act, 2021 (PSP Extension Law). Capacity Reductions We have significantly reduced our capacity (as measured by available seat miles), with first quarter of 2021 flying down 39.2% year-over-year. Domestic capacity in the first quarter of 2021 was down 36.8% while international capacity was down 45.1% year-over-year. While demand for domestic and short-haul international markets has begun to return, uncertainty continues to exist. We will continue to match our forward capacity with observed booking trends for future travel and make further adjustments to our capacity as needed. Cost Reductions We have reduced our 2021 operating expenditures as a result of permanent non-volume cost reductions. These reductions include labor productivity enhancements, management salaries and benefits and other permanent cost reductions. In the first quarter of 2021, an additional 1,600 represented team members opted in to a voluntary early retirement program. Liquidity As of March 31, 2021, we had $17.3 billion in total available liquidity, consisting of $14.0 billion in unrestricted cash and short-term investments, $2.8 billion in an undrawn capacity under revolving credit facilities and a total of $454 million in undrawn short-term revolving and other facilities. During the first quarter of 2021, we completed the following financing transactions (see Note 5 for further information): •issued $3.5 billion in aggregate principal amount of 5.50% Senior Secured Notes due 2026 and $3.0 billion in aggregate principal amount of 5.75% Senior Secured Notes due 2029 and entered into a $3.5 billion senior secured term loan facility (the AAdvantage Term Loan Facility) of which the full amount of term loans was drawn at closing; •repaid in full $750 million under the 2013 Revolving Facility, $1.6 billion under the 2014 Revolving Facility and $450 million under the April 2016 Revolving Facility, all of which was borrowed in April 2020 in response to the COVID-19 pandemic; •repaid the $550 million of outstanding loans under the $7.5 billion secured term loan facility with the U.S. Department of Treasury (Treasury) (the Treasury Loan Agreement) and terminated the Treasury Loan Agreement; •issued 18.2 million shares of AAG common stock at an average price of $17.59 per share pursuant to an at-the-market offering for net proceeds of $316 million; and •raised $99 million principally from aircraft sale-leaseback transactions. In addition to the foregoing financings, we received an aggregate of approximately $3.1 billion in financial assistance through the payroll support program (PSP2) established under the PSP Extension Law, all of which was received by the end of March 2021. In connection with our receipt of this financial assistance, AAG issued a promissory note (the PSP2 Promissory Note) to Treasury for $896 million in aggregate principal amount and warrants to purchase up to an aggregate of approximately 5.7 million shares (the PSP2 Warrant Shares) of AAG common stock. See below for further discussion on PSP2. 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/or contain loan to value, collateral coverage and/or debt service coverage ratio covenants. Given the above actions and our current assumptions about the future impact of the COVID-19 pandemic on travel demand, which could be materially different due to the inherent uncertainties of the current operating environment, we expect to meet our cash obligations as well as remain in compliance with the debt covenants in our existing financing agreements for the next 12 months based on our current level of unrestricted cash and short-term investments, our anticipated access to liquidity (including via proceeds from financings and funds from government assistance to be obtained pursuant to the American Rescue Plan Act of 2021, as amended (the ARP)), and projected cash flows from operations. PSP2 On January 15, 2021 (the PSP2 Closing Date), 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 a Payroll Support Program Extension Agreement (the PSP2 Agreement) with Treasury, with respect to PSP2 provided pursuant to the PSP Extension Law. In connection with our entry into the PSP2 Agreement, on the PSP2 Closing Date, AAG also entered into a warrant agreement (the PSP2 Warrant Agreement) with Treasury and issued the PSP2 Promissory Note to Treasury, with the Subsidiaries as guarantors. PSP2 Agreement In connection with PSP2, we are required to comply with the relevant provisions of the PSP Extension Law, which are substantially similar as the restrictions contained in the Payroll Support Program Agreement entered into by the Subsidiaries with Treasury in connection with the payroll support program established under the CARES Act, but are in effect for a longer time period. These provisions include the requirement that funds provided pursuant to the PSP2 Agreement be used exclusively for the continuation of payment of eligible employee wages, salaries and benefits, the requirement against involuntary furloughs and reductions in employee pay rates and benefits through March 31, 2021, the provisions that prohibit the repurchase of AAG common stock, and the payment of common stock dividends through at least March 31, 2022, the provisions that restrict the payment of certain executive compensation until at least October 1, 2022, as well as a requirement to recall employees involuntarily terminated or furloughed after September 30, 2020. As was the case with PSP1, the PSP2 Agreement also imposes substantial reporting obligations on us. Pursuant to the PSP2 Agreement, Treasury provided us financial assistance in two installments (each prior installment and any future installment disbursement, an Installment) totaling approximately $3.1 billion in the aggregate. As partial compensation to the U.S. Government for the provision of financial assistance under PSP2, AAG issued the PSP2 Promissory Note in the aggregate principal amount of $896 million and issued warrants (each a PSP2 Warrant and, collectively, the PSP2 Warrants) to Treasury to purchase up to an aggregate of approximately 5.7 million shares of AAG common stock. For accounting purposes, the $3.1 billion of aggregate financial assistance we received pursuant to the PSP2 Agreement is allocated to the PSP2 Promissory Note, the PSP2 Warrants and the other PSP2 financial assistance (the PSP2 Financial Assistance). The aggregate principal amount of $896 million of the PSP2 Promissory Note was recorded as unsecured long-term debt, and the total fair value of the PSP2 Warrants of $65 million, estimated using a Black-Scholes option pricing model, was recorded in stockholders' deficit in the condensed consolidated balance sheet. The remaining amount of approximately $2.1 billion of PSP2 Financial Assistance was recognized as a credit to special items, net in the condensed consolidated statement of operations in the first quarter of 2021, the remaining period over which the continuation of payment of eligible employee wages, salaries and benefits was required. PSP2 Promissory Note As partial compensation to the U.S. Government for the provision of financial assistance under the PSP2 Agreement, AAG issued the PSP2 Promissory Note to Treasury, which provides for our unconditional promise to pay to Treasury the principal sum of $896 million, subject to an increase equal to 30% of the amount of any additional Installment disbursed under the PSP2 Agreement, and the guarantee of our obligations under the PSP2 Promissory Note by the Subsidiaries. The PSP2 Promissory Note bears interest on the outstanding principal amount at a rate equal to 1.00% per annum until the fifth anniversary of the PSP2 Closing Date and 2.00% plus an interest rate based on the secured overnight financing rate per annum or other benchmark replacement rate consistent with customary market conventions (but not to be less than 0.00%) thereafter until the tenth anniversary of the PSP2 Closing Date (the PSP2 Maturity Date), and interest accrued thereon will be payable in arrears on the last business day of March and September of each year, beginning on March 31, 2021. The aggregate principal amount outstanding under the PSP2 Promissory Note, together with all accrued and unpaid interest thereon and all other amounts payable under the PSP2 Promissory Note, will be due and payable on the PSP2 Maturity Date. We may, at any time and from time to time, voluntarily prepay amounts outstanding under the PSP2 Promissory Note, in whole or in part, without penalty or premium. Within 30 days of the occurrence of certain change of control triggering events, we are required to prepay the aggregate outstanding principal amount of the PSP2 Promissory Note at such time, together with any accrued interest or other amounts owing under the PSP2 Promissory Note at such time. The PSP2 Promissory Note is our senior unsecured obligation and each guarantee of the PSP2 Promissory Note is the senior unsecured obligation of each of the Subsidiaries, respectively. The PSP2 Promissory Note contains events of default, including cross-default with respect to acceleration or failure to pay at maturity other material indebtedness. Upon the occurrence of an event of default and subject to certain grace periods, the outstanding obligations under the PSP2 Promissory Note may, and in certain circumstances will automatically, be accelerated and become due and payable immediately. PSP2 Warrant Agreement and PSP2 Warrants As partial compensation to the U.S. Government for the provision of financial assistance under the PSP2 Agreement, and pursuant to the PSP2 Warrant Agreement, AAG issued the PSP2 Warrants to Treasury to purchase PSP2 Warrant Shares. The exercise price of the PSP2 Warrant Shares is $15.66 per share, subject to certain anti-dilution provisions provided for in the PSP2 Warrants. Pursuant to the PSP2 Warrant Agreement, AAG issued to Treasury PSP2 Warrants to purchase up to an aggregate of approximately 5.7 million shares of Common Stock based on the terms described herein and on the date of any increase of the principal amount of the PSP2 Promissory Note in connection with the disbursement of any additional Installment under the PSP2 Agreement, AAG will issue to Treasury an additional PSP2 Warrant for a number of shares of AAG common stock equal to 10% of such increase of the principal amount of the PSP2 Promissory Note, divided by $15.66, the exercise price of such shares. The PSP2 Warrants do not have any voting rights and are freely transferrable, with registration rights. Each PSP2 Warrant expires on the fifth anniversary of the date of issuance of such PSP2 Warrant. The PSP2 Warrants will be exercisable either through net share settlement or cash, at our option. The PSP2 Warrants were and will be issued solely as compensation to the U.S. Government related to entry into the PSP2 Agreement. No separate proceeds (apart from the financial assistance described above) were received upon issuance of the PSP2 Warrants or will be received upon exercise thereof. (c) Recent Accounting Pronouncements ASU 2020-06: Accounting for Convertible Instruments and Contracts In An Entity's Own Equity (the New Convertible Debt Standard) The New Convertible Debt Standard simplifies the accounting for certain convertible instruments by removing the separation models for convertible debt with a cash conversion feature and for convertible instruments with a beneficial conversion feature. As a result, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features. Additionally, the New Convertible Debt Standard amends the diluted earnings per share calculation for convertible instruments by requiring the use of the if-converted method. The treasury stock method is no longer available. Entities may adopt the New Convertible Debt Standard using either a full or modified retrospective approach, and it is effective for interim and annual reporting periods beginning after December 15, 2021. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2020. The New Convertible Debt Standard is applicable to our 6.50% convertible senior notes due 2025 (the Convertible Notes). We early adopted the New Convertible Debt Standard as of January 1, 2021 using the modified retrospective method to recognize our Convertible Notes as a single liability instrument. As of January 1, 2021, we recorded a $415 million ($320 million net of tax) reduction to additional paid-in capital to remove the equity component of the Convertible Notes from our balance sheet and a $19 million cumulative effect adjustment credit, net of tax, to retained deficit related to non-cash debt discount amortization recognized in periods prior to adoption resulting in a corresponding reduction of $389 million to the debt discount associated with the Convertible Notes. ASU 2019-12: Simplifying the Accounting for Income Taxes (Topic 740) This standard simplifies the accounting and disclosure requirements for income taxes by clarifying the existing guidance to improve consistency in the application of Accounting Standards Codification 740. This standard also removed the requirement to calculate income tax expense for the stand-alone financial statements of wholly-owned subsidiaries that are not subject to income tax. We adopted this standard effective January 1, 2021, and it did not have a material impact on our condensed consolidated financial statements.

Each PSP2 Warrant expires on the fifth anniversary of the date of issuance of such PSP2 Warrant. The PSP2 Warrants will be exercisable either through net share settlement or cash, at AAG’s option. The PSP2 Warrants were and will be issued solely as compensation to the U.S. Government related to entry into the PSP2 Agreement. No separate proceeds (apart from the financial assistance described above) were received upon issuance of the PSP2 Warrants or will be received upon exercise thereof. (c) Recent Accounting Pronouncement Accounting Standards Update 2019-12: Simplifying the Accounting for Income Taxes (Topic 740) This standard simplifies the accounting and disclosure requirements for income taxes by clarifying the existing guidance to improve consistency in the application of Accounting Standards Codification 740. This standard also removed the requirement to calculate income tax expense for the stand-alone financial statements of wholly-owned subsidiaries that are not subject to income tax. American adopted this standard effective January 1, 2021, and it did not have a material impact on its condensed consolidated financial statements.

Revenue

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


	Three Months Ended March 31,
	2021		2020
Passenger revenue:
Passenger travel	$	2,893	$	7,079
Loyalty revenue - travel (1)	286		602

Cargo	315		147

Other revenue	57		116
Total other revenue	514		687
Total operating revenues	$	4,008	$	8,515

(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.

(2)During the three months ended March 31, 2021 and 2020, cash payments from co-branded credit card and other partners was $1.0 billion and $1.3 billion, respectively.

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


	Three Months Ended March 31,
	2021		2020
Domestic	$	2,655	$	5,780
Latin America	482		1,180
Atlantic	22		523
Pacific	20		198
Total passenger revenue	$	3,179	$	7,681

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

Contract Balances

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


	March 31, 2021		December 31, 2020
	(In millions)
Loyalty program liability	$	9,378	$	9,195
Air traffic liability	5,598		4,757
Total	$	14,976	$	13,952

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, 2020	$	9,195
Deferral of revenue	490
Recognition of revenue (1)	(307)
Balance at March 31, 2021 (2)	$	9,378

(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 miles that were part of the loyalty program deferred revenue balance at the beginning of the period, as well as miles 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 18 months. In response to the COVID-19 pandemic, we suspended the expiration of mileage credits through June 30, 2021 and eliminated mileage reinstatement fees for canceled award tickets. As of March 31, 2021, our current loyalty program liability was $2.3 billion and represents our current estimate of revenue expected to be recognized in the next 12 months based on historical as well as projected trends, with the balance reflected in long-term loyalty program liability expected to be recognized as revenue in periods thereafter. Given the inherent uncertainty of the current operating environment due to the COVID-19 pandemic, we will continue to monitor redemption patterns and may adjust our estimates in the future.

The air traffic liability principally represents tickets sold for future travel on American and partner airlines, as well as estimated future refunds and exchanges of tickets sold for past travel. 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 the three months ended March 31, 2021, $838 million of revenue was recognized in passenger revenue that was included in our air traffic liability at December 31, 2020. In response to the COVID-19 pandemic, we extended the contract duration for certain tickets to March 31, 2022, principally those tickets which were scheduled to expire from March 1, 2020 through March 31, 2021. Additionally, we have eliminated change fees for most domestic and international tickets. As of March 31, 2021, the air traffic liability included approximately $2.1 billion of travel credits related to these unused tickets. Accordingly, any revenue associated with these tickets will be recognized within the next 12 months. Given this change in contract duration and uncertainty surrounding the future demand for air travel, our estimates of revenue that will be recognized from the air traffic liability for future flown or unused tickets as well as our estimates of refunds may be subject to variability and differ from historical experience.

American has an undrawn $400 million short-term revolving credit facility it entered into in December 2019, which was set to expire at the end of December 2020 but which has been extended through the beginning of July 2021. American has the option to extend further this short-term revolving credit facility to January 2022 and, if extended, the available amount thereunder for the period from July 2021 to January 2022 shall be increased to $500 million. American also currently has approximately $54 million of available borrowing base under a cargo receivables facility that was entered into in December 2020. The December 2016 Credit Facilities provide for a revolving credit facility that may be established thereunder in the future.

Secured financings are collateralized by assets, consisting primarily of aircraft, engines, simulators, aircraft spare parts, airport gate leasehold rights, route authorities, airport slots and certain pre-delivery payments, as well as certain intellectual property and loyalty program assets.

6.50% Convertible Senior Notes

At March 31, 2021, the if-converted value of the Convertible Notes exceeded the principal amount by $475 million. The last reported sale price per share of our common stock (as defined in the indenture governing our Convertible Notes, the Convertible Notes Indenture) exceeded 130% of the conversion price of the Convertible Notes for each of at least 20 trading days during the 30 consecutive trading days ending on March 31, 2021. Accordingly, pursuant to the terms of the Convertible Notes Indenture, the holders of the Convertible Notes may convert at their option at any time during the quarter ending June 30, 2021. 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. We may settle conversions by paying or delivering, as applicable, cash, shares of our common stock or a combination of cash and shares of our common stock, at our election.

2021 Financing Activities

2013, 2014 and April 2016 Revolving Facilities

In March 2021, American repaid in full the $750 million of revolving loans outstanding under the 2013 Revolving Facility, the $1.6 billion of revolving loans outstanding under the 2014 Revolving Facility and the $450 million of revolving loans outstanding under the April 2016 Revolving Facility. Following the March 2021 repayment, American is able to draw upon the commitments under these revolving facilities again as needed upon the terms of the underlying credit agreements or leave them undrawn, in each case, until such commitments expire, which is currently scheduled to occur in 2024 for substantially all of such commitments. As of March 31, 2021, there were no borrowings or letters of credit outstanding under the 2013 Revolving Facility, the 2014 Revolving Facility or the April 2016 Revolving Facility.

PSP2 Promissory Note

As partial compensation to the U.S. Government for the provision of financial assistance under the PSP2 Agreement, AAG issued the PSP2 Promissory Note to Treasury, which provides for our unconditional promise to pay to Treasury the principal sum of $896 million, subject to an increase equal to 30% of the amount of any additional Installment disbursed under the PSP2 Agreement, and the guarantee of our obligations under the PSP2 Promissory Note by the Subsidiaries.

The PSP2 Promissory Note bears interest on the outstanding principal amount at a rate equal to 1.00% per annum until the fifth anniversary of the PSP2 Closing Date and 2.00% plus an interest rate based on the secured overnight financing rate per annum or other benchmark replacement rate consistent with customary market conventions (but not to be less than 0.00%) thereafter until the tenth anniversary of the PSP2 Closing Date (the PSP2 Maturity Date), and interest accrued thereon will be payable in arrears on the last business day of March and September of each year, beginning on March 31, 2021. The aggregate principal amount outstanding under the PSP2 Promissory Note, together with all accrued and unpaid interest thereon and all other amounts payable under the PSP2 Promissory Note, will be due and payable on the PSP2 Maturity Date.

We may, at any time and from time to time, voluntarily prepay amounts outstanding under the PSP2 Promissory Note, in whole or in part, without penalty or premium. Within 30 days of the occurrence of certain change of control triggering events, we are required to prepay the aggregate outstanding principal amount of the PSP2 Promissory Note at such time, together with any accrued interest or other amounts owing under the PSP2 Promissory Note at such time.

The PSP2 Promissory Note is our senior unsecured obligation and each guarantee of the PSP2 Promissory Note is the senior unsecured obligation of each of the Subsidiaries, respectively.

The PSP2 Promissory Note contains events of default, including cross-default with respect to acceleration or failure to pay at maturity other material indebtedness. Upon the occurrence of an event of default and subject to certain grace periods, the outstanding obligations under the PSP2 Promissory Note may, and in certain circumstances will automatically, be accelerated and become due and payable immediately.

AAdvantage Financing

On March 24, 2021 (the AAdvantage Financing Closing Date), American and AAdvantage Loyalty IP Ltd., a newly formed Cayman Islands exempted company incorporated with limited liability and an indirect wholly owned subsidiary of American (Loyalty Issuer and, together with American, the AAdvantage Issuers), completed the offering of $3.5 billion aggregate principal amount of 5.50% Senior Secured Notes due 2026 (the 2026 Notes) and $3.0 billion aggregate principal amount of 5.75% Senior Secured Notes due 2029 (the 2029 Notes, and together with the 2026 Notes, the AAdvantage Notes). The AAdvantage Notes are fully and unconditionally guaranteed (the AAdvantage Note Guarantees) on a senior unsecured basis by AAG and fully and unconditionally guaranteed on a senior secured basis, jointly and severally, by AAdvantage Holdings 1, Ltd., a newly formed Cayman Islands exempted company incorporated with limited liability and a direct wholly owned subsidiary of American, and AAdvantage Holdings 2, Ltd., a newly formed Cayman Islands exempted company incorporated with limited liability and an indirect wholly owned subsidiary of American and the direct parent of Loyalty Issuer (HoldCo2 and, together with AAdvantage Holdings 1, Ltd., the SPV Guarantors, and the SPV Guarantors together with AAG, the AAdvantage Guarantors). The AAdvantage Notes were issued pursuant to an indenture, dated as of March 24, 2021 (the AAdvantage Indenture), by and among the AAdvantage Issuers, the AAdvantage Guarantors and Wilmington Trust, National Association, as trustee and as collateral custodian.

Concurrent with the issuance of the AAdvantage Notes, the AAdvantage Issuers, as co-borrowers, entered into a term loan credit and guaranty agreement, dated March 24, 2021, with Barclays Bank PLC, as administrative agent, Wilmington Trust, National Association, as collateral administrator, and the lenders party thereto, providing for a $3.5 billion term loan facility (the AAdvantage Term Loan Facility and collectively with the AAdvantage Notes, the AAdvantage Financing) and pursuant to which the full $3.5 billion of term loans (the AAdvantage Loans) were drawn on the AAdvantage Financing Closing Date. The AAdvantage Loans are fully and unconditionally guaranteed (together with the AAdvantage Note Guarantees, the AAdvantage Guarantees) by the AAdvantage Guarantors.

Subject to certain permitted liens and other exceptions, the AAdvantage Notes, AAdvantage Loans and AAdvantage Guarantees provided by the SPV Guarantors will be secured by a first-priority security interest in, and pledge of, various agreements with respect to the AAdvantage program (the AAdvantage Agreements) (including all payments thereunder) and rights under an intercompany agreement and certain IP Licenses (as defined below), certain rights under the AAdvantage program, certain deposit accounts that will receive cash under the AAdvantage Agreements, certain reserve accounts, the equity of each of Loyalty Issuer and the SPV Guarantors and substantially all other assets of Loyalty Issuer and the SPV Guarantors (collectively, the AAdvantage Collateral).

Payment Terms of the AAdvantage Notes and AAdvantage Loans under the AAdvantage Term Loan Facility

Interest on the AAdvantage Notes is payable in cash, quarterly in arrears on the 20th day of each January, April, July and October (each, an AAdvantage Payment Date), beginning July 20, 2021. The 2026 Notes will mature on April 20, 2026, and the 2029 Notes will mature on April 20, 2029. The outstanding principal on the 2026 Notes will be repaid in quarterly installments of approximately $292 million on each AAdvantage Payment Date, beginning on July 20, 2023. The outstanding principal on the 2029 Notes will be repaid in quarterly installments of $250 million on each AAdvantage Payment Date, beginning on July 20, 2026.

The AAdvantage Issuers may redeem the AAdvantage Notes, at their option, in whole at any time or in part from time to time, at a redemption price equal to 100% of the principal amount of the AAdvantage Notes redeemed plus a “make-whole” premium, together with accrued and unpaid interest to the date of redemption.

The scheduled maturity date of the AAdvantage Loans under the AAdvantage Term Loan Facility is April 20, 2028. The AAdvantage Loans bear interest at a variable rate equal to LIBOR (but not less than 0.75% per annum), plus a margin of 4.75% per annum, payable on each AAdvantage Payment Date. The outstanding principal on the AAdvantage Loans will be repaid in quarterly installments of $175 million, on each AAdvantage Payment Date beginning with the AAdvantage Payment Date in July 2023. These amortization payments (as well as those for the AAdvantage Notes) will be subject to the occurrence of certain early amortization events, including the failure to satisfy a minimum debt service coverage ratio at specified determination dates.

Prepayment of some or all of the AAdvantage Loans outstanding under the AAdvantage Term Loan Facility is permitted, although payment of an applicable premium is required as specified in the AAdvantage Term Loan Facility.

The AAdvantage Indenture and the AAdvantage Term Loan Facility contain mandatory prepayment provisions triggered upon (i) the issuance or incurrence by Loyalty Issuer or the SPV Guarantors of certain indebtedness or (ii) the receipt by American or its subsidiaries of net proceeds from pre-paid frequent flyer (i.e., AAdvantage) mile purchases exceeding $500 million, with prepayment required only in respect of net proceeds from such purchases exceeding $505 million in the aggregate. Each of these prepayments would also require payment of an applicable premium. Certain other events, including the occurrence of a change of control with respect to AAG and certain AAdvantage Collateral sales exceeding a specified threshold, will also trigger mandatory repurchase or mandatory prepayment provisions under the AAdvantage Indenture and the AAdvantage Term Loan Facility, respectively.

Other Terms of the AAdvantage Indenture and the AAdvantage Term Loan Facility

The AAdvantage Indenture and the AAdvantage Term Loan Facility contain certain covenants that limit the ability of Loyalty Issuer, the SPV Guarantors and, in certain circumstances, American and AAG, to among other things, (i) incur additional indebtedness and make restricted payments, (ii) incur certain liens on the AAdvantage Collateral, (iii) merge, consolidate or sell substantially all of their assets, (iv) dispose of the AAdvantage Collateral, (v) sell pre-paid frequent flyer (i.e. AAdvantage) miles in excess of $550 million in the aggregate, and (vi) terminate, amend, waive, supplement or modify the IP Licenses, or exercise rights and remedies thereunder, except under certain circumstances. American and Loyalty Issuer are also prohibited from substantially reducing the AAdvantage program business or modifying the terms of the AAdvantage program in a manner that would reasonably be expected to materially impair repayment of the AAdvantage Financing obligations (described as a Payment Material Adverse Effect in the AAdvantage Indenture and the AAdvantage Term Loan Facility), and AAG and its subsidiaries are prohibited from changing the policies and procedures of the AAdvantage program in a manner that would reasonably be expected to have a Payment Material Adverse Effect or operating a competing loyalty program. Notwithstanding these restrictions, the AAdvantage program is expected to operate as it has in the past, and the entry into the AAdvantage Financing is not expected to have any impact on the benefits offered to AAdvantage members.

In addition, subject to certain exceptions, the AAdvantage Indenture and the AAdvantage Term Loan Facility restrict the ability of American, Loyalty Issuer or any Guarantor to terminate, or modify certain terms within, the intercompany agreement governing the relationship between American and Loyalty Issuer with respect to the AAdvantage program.

The AAdvantage Indenture and the AAdvantage Term Loan Facility also require the AAdvantage Issuers to comply with certain affirmative covenants, including (i) certain reporting requirements and (ii) the use of commercially reasonable efforts to cause sufficient counterparties to AAdvantage Agreements to direct payments with respect to the AAdvantage program into a collections account, such that at least 90% of such cash receipts in a quarterly reporting period are deposited directly into this collection account, with amounts to be distributed from this collection account for the payment of fees, principal and interest on the AAdvantage Notes and the AAdvantage Loans pursuant to a payment waterfall described in the AAdvantage Indenture and the AAdvantage Term Loan Facility, respectively. In addition, the AAdvantage Indenture and the AAdvantage Term Loan Facility require AAG to maintain minimum liquidity, defined as the sum of (a) unrestricted cash and cash equivalents and (b) the aggregate principal amount committed and available to be drawn under all of AAG's revolving credit and other facilities, at the close of any business day of at least $2.0 billion.

Subject to certain materiality thresholds, qualifications, exceptions, “baskets” and grace and cure periods, the AAdvantage Indenture and the AAdvantage Term Loan Facility contain various events of default, including payment defaults, covenant defaults, cross-defaults to certain indebtedness, termination of certain agreements related to the AAdvantage program, bankruptcy events of Loyalty Issuer or any SPV Guarantor, and a change of control of Loyalty Issuer or any SPV Guarantor. A bankruptcy event of American is not itself an event of default; following an American bankruptcy, an event of default would only occur if American failed to satisfy certain enumerated bankruptcy case milestones, including an assumption of the AAdvantage Financing by a certain date. Upon the occurrence of an event of

default, the outstanding obligations under the AAdvantage Indenture and the AAdvantage Term Loan Facility may (or, with respect to the bankruptcy events noted above, shall) be accelerated and become due and payable immediately.

Terms of Certain Intercompany Agreements Related to the AAdvantage Financing

In connection with the issuance of the AAdvantage Notes and entry into the AAdvantage Term Loan Facility, American, Loyalty Issuer and the SPV Guarantors entered into a series of transactions that resulted in the transfer to Loyalty Issuer of, among other things, American’s rights to certain data and other intellectual property used in the AAdvantage program (subject to certain exceptions) (such assets, the Transferred AAdvantage IP) and certain rights of American under specified AAdvantage Agreements. Loyalty Issuer has entered into a license agreement with HoldCo2 pursuant to which Loyalty Issuer has granted to HoldCo2 an exclusive, irrevocable (subject to certain termination rights), perpetual, worldwide, royalty-bearing license to use the Transferred AAdvantage IP (the HoldCo2 License), and HoldCo2 has in turn granted to American an exclusive, irrevocable (subject to certain termination rights), perpetual, worldwide, royalty-bearing sublicense to use the Transferred AAdvantage IP (together with the HoldCo2 License, the IP Licenses). The IP Licenses would be terminated, and American’s right to use the Transferred AAdvantage IP would cease, upon specified termination events, including, but not limited to, the occurrence of an event of default under the AAdvantage Indenture or the AAdvantage Term Loan Facility. In certain circumstances, such a termination would trigger a liquidated damages payment in an amount that is greater than the initial principal amount of the AAdvantage Notes and the AAdvantage Loans.

In addition, proceeds from the AAdvantage Financing were loaned by Loyalty Issuer to American pursuant to an intercompany note that was guaranteed by AAG. The borrowings under this intercompany note are payable on demand by Loyalty Issuer or, after the occurrence and during the continuance of an event of default under the AAdvantage Financing, by the master collateral agent under the AAdvantage Financing.

Treasury Loan Agreement

On September 25, 2020, American and AAG 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, American and AAG entered into an amendment to the Treasury Loan Agreement, which increased the borrowing amount to up to $7.5 billion. American had borrowed $550 million under the Treasury Term Loan Facility in September 2020.

On March 24, 2021, American used proceeds from the AAdvantage Financing to prepay in full the $550 million outstanding under the Treasury Term Loan Facility and terminated the Treasury Loan Agreement.

Fair Value Measurements and Other Investments

Assets Measured at Fair Value on a Recurring Basis

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 classified as Level 2 primarily utilize broker quotes in a non-active market for valuation of these securities. No changes in valuation techniques or inputs occurred during the three months ended March 31, 2021.

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


	Fair Value Measurements as of March 31, 2021

(1)All short-term investments are classified as available-for-sale and stated at fair value. Unrealized gains and losses are recorded in accumulated other comprehensive loss at each reporting period. There were no credit losses.

(2)Our short-term investments mature in one year or less.

(3)Restricted cash and short-term investments primarily include money market funds to be used to finance a substantial portion of the cost of the renovation and expansion of Terminal 8 at JFK as well as collateral associated with the payment of certain fees and interest in respect of the AAdvantage Financing and collateral held to support workers' compensation obligations.

(4)Long-term investments primarily include our equity investment in China Southern Airlines, in which we presently own a 1.8% equity interest, and are classified in other assets on the condensed consolidated balance sheet.

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 $2.7 billion and $2.3 billion as of March 31, 2021 and December 31, 2020, respectively, which would have been classified as Level 3 in the fair value hierarchy. The fair value of our Convertible Notes was $1.7 billion and $1.2 billion as of March 31, 2021 and December 31, 2020, respectively.

For the three months ended March 31, 2021, American recognized a $139 million special charge for these enhanced healthcare benefits and increased its postretirement benefits obligation by $139 million as of March 31, 2021.

In January 2021, American made $241 million in contributions to its pension plans, including a contribution of $130 million for the 2020 calendar year that was permitted to be deferred to January 4, 2021 as provided under the CARES Act. On March 11, 2021, the ARP was enacted, which included certain funding relief provisions for single employer qualified retirement benefit pension plans such as those sponsored by American. Based on American's current understanding of the ARP provisions applicable to its pension plans, American will have no additional funding requirements for 2021.

Long-term Purchase Commitment [Line Items]
Legal Proceedings	Legal Proceedings Chapter 11 Cases. On November 29, 2011, AMR Corporation (AMR), American, and certain of AMR’s other direct and indirect domestic subsidiaries (the Debtors) filed voluntary petitions for relief under Chapter 11 of the United States Bankruptcy Code in the United States Bankruptcy Court for the Southern District of New York (the Bankruptcy Court). On October 21, 2013, the Bankruptcy Court entered an order approving and confirming the Debtors’ fourth amended joint plan of reorganization (as amended, the Plan). On the Effective Date, December 9, 2013, the Debtors consummated their reorganization pursuant to the Plan and completed the acquisition of US Airways Group, Inc. by AMR (the Merger). Pursuant to rulings of the Bankruptcy Court, the Plan established a disputed claims reserve (the Disputed Claims Reserve) to hold shares of AAG common stock reserved for issuance to disputed claimholders at the Effective Date that ultimately become holders of allowed claims. The shares of AAG common stock issued to the Disputed Claims Reserve were originally issued on December 13, 2013 and have at all times since been included in the number of shares issued and outstanding as reported from time to time in our quarterly and annual reports, including for calculating earnings per common share. As disputed claims are resolved, the claimants receive distributions of shares from the Disputed Claims Reserve. We are not required to distribute additional shares above the limits contemplated by the Plan, even if the shares remaining for distribution in the Disputed Claims Reserve are not sufficient to fully pay any additional allowed unsecured claims. If any of the reserved shares remain undistributed upon resolution of all remaining disputed claims, such shares will not be returned to us but rather will be distributed to former AMR stockholders and former convertible noteholders treated as stockholders under the Plan. As of March 31, 2021, the Disputed Claims Reserve held approximately 4.8 million shares of AAG common stock. Private Party Antitrust Action Related to Passenger Capacity. We, along with Delta Air Lines, Inc., Southwest Airlines Co., United Airlines, Inc. and, in the case of litigation filed in Canada, Air Canada, were named as defendants in approximately 100 putative class action lawsuits alleging unlawful agreements with respect to air passenger capacity. The U.S. lawsuits were consolidated in the Federal District Court for the District of Columbia (the DC Court). On June 15, 2018, we reached a settlement agreement with the plaintiffs in the amount of $45 million to resolve all class claims in the U.S. lawsuits. That settlement was approved by the DC Court on May 13, 2019, however three parties who objected to the settlement have appealed that decision to the United States Court of Appeals for the District of Columbia. We believe these appeals are without merit and intend to vigorously defend against them. Private Party Antitrust Action Related to the Merger. On August 6, 2013, a lawsuit captioned Carolyn Fjord, et al., v. AMR Corporation, et al., was filed in the Bankruptcy Court. The complaint named as defendants US Airways Group, Inc., US Airways, Inc., AMR and American, alleged that the effect of the Merger may be to create a monopoly in violation of Section 7 of the Clayton Antitrust Act, and sought injunctive relief and/or divestiture. On November 27, 2013, the Bankruptcy Court denied plaintiffs’ motion to preliminarily enjoin the Merger. On August 29, 2018, the Bankruptcy Court denied in part defendants' motion for summary judgment, and fully denied plaintiffs' cross-motion for summary judgment. The parties' evidentiary cases were presented before the Bankruptcy Court in a bench trial in March 2019 and the parties submitted proposed findings of fact and conclusions of law and made closing arguments in April 2019. On January 29, 2021, the Bankruptcy Court published its decision finding in our favor. The plaintiffs have appealed this ruling. We believe this lawsuit is without merit and intend to continue to vigorously defend against the allegations, including plaintiffs' appeal of the Bankruptcy Court's January 29, 2021 ruling. 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.

Basis of Presentation	Basis of Presentation The accompanying unaudited condensed consolidated financial statements of American Airlines Group Inc. (we, us, our and similar terms, or AAG) should be read in conjunction with the consolidated financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2020. The accompanying unaudited condensed consolidated financial statements include the accounts of AAG and its wholly-owned subsidiaries. AAG’s principal subsidiary is American Airlines, Inc. (American). All significant intercompany transactions have been eliminated. Management believes that all adjustments necessary for the fair presentation of results, consisting of normally recurring items, have been included in the unaudited condensed consolidated financial statements for the interim periods presented. 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, impairment of goodwill, impairment of long-lived and intangible assets, the loyalty program, deferred tax assets, as well as pension and retiree medical and other postretirement benefits. Certain prior period amounts have been reclassified to conform to the current year presentation. See Note 10 for further information.
Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU 2020-06: Accounting for Convertible Instruments and Contracts In An Entity's Own Equity (the New Convertible Debt Standard) The New Convertible Debt Standard simplifies the accounting for certain convertible instruments by removing the separation models for convertible debt with a cash conversion feature and for convertible instruments with a beneficial conversion feature. As a result, more convertible debt instruments will be reported as a single liability instrument with no separate accounting for embedded conversion features. Additionally, the New Convertible Debt Standard amends the diluted earnings per share calculation for convertible instruments by requiring the use of the if-converted method. The treasury stock method is no longer available. Entities may adopt the New Convertible Debt Standard using either a full or modified retrospective approach, and it is effective for interim and annual reporting periods beginning after December 15, 2021. Early adoption is permitted for interim and annual reporting periods beginning after December 15, 2020. The New Convertible Debt Standard is applicable to our 6.50% convertible senior notes due 2025 (the Convertible Notes). We early adopted the New Convertible Debt Standard as of January 1, 2021 using the modified retrospective method to recognize our Convertible Notes as a single liability instrument. As of January 1, 2021, we recorded a $415 million ($320 million net of tax) reduction to additional paid-in capital to remove the equity component of the Convertible Notes from our balance sheet and a $19 million cumulative effect adjustment credit, net of tax, to retained deficit related to non-cash debt discount amortization recognized in periods prior to adoption resulting in a corresponding reduction of $389 million to the debt discount associated with the Convertible Notes. ASU 2019-12: Simplifying the Accounting for Income Taxes (Topic 740) This standard simplifies the accounting and disclosure requirements for income taxes by clarifying the existing guidance to improve consistency in the application of Accounting Standards Codification 740. This standard also removed the requirement to calculate income tax expense for the stand-alone financial statements of wholly-owned subsidiaries that are not subject to income tax. We adopted this standard effective January 1, 2021, and it did not have a material impact on our condensed consolidated financial statements.

(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 18 months. In response to the COVID-19 pandemic, American suspended the expiration of mileage credits through June 30, 2021 and eliminated mileage reinstatement fees for canceled award tickets. As of March 31, 2021, American's current loyalty program liability was $2.3 billion and represents American's current estimate of revenue expected to be recognized in the next 12 months based on historical as well as projected trends, with the balance reflected in long-term loyalty program liability expected to be recognized as revenue in periods thereafter. Given the inherent uncertainty of the current operating environment due to the COVID-19 pandemic, American will continue to monitor redemption patterns and may adjust its estimates in the future.
