Basis of Presentation	9 Months Ended
Basis of Presentation	Sep. 30, 2016
Basis of Presentation	1. 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, 2015. 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. On December 9, 2013 (the Effective Date), AMR Merger Sub, Inc. merged with and into US Airways Group, Inc. (US Airways Group) (the Merger), with US Airways Group surviving as a wholly-owned subsidiary of AAG, a Delaware corporation (formerly known as AMR Corporation or AMR) following the Merger. On December 30, 2015, in order to simplify our internal corporate structure and as part of the integration efforts following the business combination of AAG and US Airways Group, AAG caused US Airways Group to be merged with and into AAG, with AAG as the surviving corporation, and, immediately thereafter, US Airways, Inc. (US Airways), a Delaware corporation and wholly-owned subsidiary of US Airways Group, merged with and into American, with American as the surviving corporation. As a result of the merger of US Airways and American, US Airways transferred all of its assets, liabilities and off-balance sheet commitments to American. For financial reporting purposes, this transaction constituted a transfer of assets between entities under common control and was accounted for at historical cost. 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, as well as pensions, retiree medical and other postretirement benefits. *Recent Accounting Pronouncements* In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 completes the joint effort by the FASB and International Accounting Standards Board (IASB) to improve financial reporting by creating common revenue recognition guidance for GAAP and International Financial Reporting Standards (IFRS). Subsequently, the FASB has issued several additional ASUs to clarify the implementation guidance on principal versus agent considerations, identifying performance obligations, assessing collectability, presentation of sales taxes and other similar taxes collected from customers, non-cash consideration, contract modifications and completed contracts at transition. These ASUs apply to all companies that enter into contracts with customers to transfer goods or services. These ASUs are effective for public entities for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before interim and annual reporting periods beginning after December 15, 2016. Entities have the choice to apply these ASUs either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying these standards at the date of initial application and not adjusting comparative information. We are currently evaluating the requirements of these standards and have not yet determined the impact on our condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet and aligns many of the underlying principles of the new lessor model with those in Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-02 and have not yet determined its impact on our condensed consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies the accounting for share-based payment award transactions including the financial statement presentation of excess tax benefits and deficiencies, classification of awards as either equity or liabilities, accounting for forfeitures and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We early adopted this standard during the second quarter of 2016. The adoption of this standard resulted in the recognition of $418 million of previously unrecognized excess tax benefits in deferred tax assets and an increase to retained earnings on the condensed consolidated balance sheet as of the beginning of the current year, and the recognition of $9 million of excess tax benefits to the income tax provision for the nine months ended September 30, 2016.

Basis of Presentation	1. Basis of Presentation The accompanying unaudited condensed consolidated financial statements of American Airlines, Inc. (American) should be read in conjunction with the consolidated financial statements contained in American’s Annual Report on Form 10-K for the year ended December 31, 2015. American is the principal wholly-owned subsidiary of American Airlines Group Inc. (AAG). All significant intercompany transactions have been eliminated.

As a result of the merger of US Airways and American, US Airways transferred all of its assets, liabilities and off-balance sheet commitments to American. For financial reporting purposes, this transaction constituted a transfer of assets between entities under common control and is reflected in American’s condensed consolidated financial statements as though the transaction had occurred on December 9, 2013, when a subsidiary of AMR merged with and into US Airways Group, which represents the earliest date that American and US Airways were under common control. Thus, all periods presented in Part I, Item 1B of this Quarterly Report on Form 10-Q are comprised of the condensed consolidated financial data of American and US Airways. This transaction was accounted for in a manner similar to the pooling of interests method of accounting. Under this method, the carrying amount of net assets recognized in the balance sheets of each combining entity are carried forward to the balance sheet of the combined entity and no other assets or liabilities are recognized. 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 2015 nine month period mainline operating special items totaled a net charge of $610 million, which principally included $741 million of merger integration expenses and a $38 million charge in connection with the dissolution of a joint venture. These charges were offset in part by a $75 million net credit for bankruptcy related items principally consisting of fair value adjustments for bankruptcy settlement obligations and a $66 million credit related to proceeds received from a legal settlement. For the 2015 third quarter and nine month periods, merger integration expenses included costs related to information technology, fleet restructuring, alignment of labor union contracts, professional fees, severance, relocation and training, re-branding of aircraft, airport facilities and uniforms, as well as share-based compensation.

The 2015 third quarter nonoperating special items totaled a net charge of $21 million, which was primarily due to non-cash write offs of unamortized debt discount and debt issuance costs associated with the purchase and subsequent remarketing of certain special facility revenue bonds. The 2015 nine month period nonoperating special items totaled a net charge of $2 million, which principally included $40 million in charges primarily related to non-cash write offs of unamortized debt discount and debt issuance costs associated with refinancing American’s secured term loan facilities, prepayments of certain aircraft financings and the purchase and subsequent remarketing of certain special facility revenue bonds. These charges were offset in part by a $22 million gain associated with the sale of an investment and a $17 million early debt extinguishment gain associated with the repayment of American’s AAdvantage loan with Citibank.

Share Repurchase Programs and Dividends

4. Share Repurchase Programs and Dividends

Since July 2014, our Board of Directors has approved several share repurchase programs aggregating $9.0 billion of authority of which, as of September 30, 2016, $555 million remained unused under repurchase programs that expire on December 31, 2017. Share repurchases under our share repurchase programs may be made through a variety of methods, which may include open market purchases, privately negotiated transactions, block trades or accelerated share repurchase transactions. Any such repurchases will be made from time to time subject to market and economic conditions, applicable legal requirements and other relevant factors. Our share repurchase programs do not obligate us to repurchase any specific number of shares and may be suspended at any time at our discretion.

During the three months ended September 30, 2016, we repurchased 18.2 million shares of AAG common stock for $616 million at a weighted average cost per share of $33.87. During the nine months ended September 30, 2016, we repurchased 107.7 million shares of AAG common stock for $3.9 billion at a weighted average cost per share of $35.87. Since the inception of the share repurchase programs in July 2014, we have repurchased 216.2 million shares of AAG common stock for $8.4 billion at a weighted average cost per share of $39.06.

Our Board of Directors declared the following cash dividends during the first nine months of 2016:


Period	Per share		For stockholders of record as of		Payable on		Cash paid (millions)
First Quarter	$	0.10		February 10, 2016		February 24, 2016	$	61

Third Quarter	$	0.10		August 5, 2016		August 19, 2016		53

Total							$	172

Any future dividends that may be declared and paid from time to time will be subject to market and economic conditions, applicable legal requirements and other relevant factors. We are not obligated to continue a dividend for any fixed period, and payment of dividends may be suspended at any time at our discretion.

2016 Aircraft Financing Activities

2016-1 EETCs

In January 2016, American created three pass-through trusts which issued approximately $1.1 billion aggregate face amount of Series 2016-1 Class AA, Class A and Class B EETCs (the 2016-1 EETCs) in connection with the financing of 22 aircraft owned by American (the 2016-1 EETC Aircraft).

All of the proceeds received from the sale of the 2016-1 EETCs have been used to purchase equipment notes issued by American in three series: Series AA equipment notes in the principal amount of $584 million bearing interest at 3.575% per annum, Series A equipment notes in the principal amount of $262 million bearing interest at 4.10% per annum and Series B equipment notes in the principal amount of $228 million bearing interest at 5.25% per annum. Interest and principal payments on the equipment notes are payable semi-annually in January and July of each year, beginning in July 2016. The final payments on the Series AA and Series A equipment notes are due in January 2028 and the final payment on the Series B equipment notes is due in January 2024. These equipment notes are secured by liens on the 2016-1 EETC Aircraft.

2016-2 EETCs

In May and July 2016, American created three pass-through trusts which issued approximately $1.1 billion aggregate face amount of Series 2016-2 Class AA, Class A and Class B EETCs (the 2016-2 EETCs) in connection with the financing of 22 aircraft owned by American (the 2016-2 EETC Aircraft).

All of the proceeds received from the sale of the 2016-2 EETCs have been used to purchase equipment notes issued by American in three series: Series AA equipment notes in the principal amount of $567 million bearing interest at 3.20% per annum, Series A equipment notes in the principal amount of $261 million bearing interest at 3.65% per annum and Series B equipment notes in the principal amount of $227 million bearing interest at 4.375% per annum. Interest and principal payments on the equipment notes are payable semi-annually in June and December of each year, with interest payments beginning in December 2016 and principal payments beginning in June 2017. The final payments on the Series AA and Series A equipment notes are due in June 2028 and the final payments on the Series B equipment notes are due in June 2024. These equipment notes are secured by liens on the 2016-2 EETC Aircraft.

Other Aircraft Financing Transactions

In the first nine months of 2016, American entered into loan agreements to borrow $1.4 billion in connection with the financing of certain aircraft. Debt incurred under these loan agreements matures in 2026 through 2028 and bears interest at a rate of LIBOR plus an applicable margin.

2016 Other Financing Activities

2016 Credit Facilities

On April 29, 2016, American and AAG entered into a Credit and Guaranty Agreement (the 2016 Credit Agreement), among American, as the borrower, AAG as parent and guarantor, Barclays Bank PLC, as administrative agent and collateral agent and certain lenders. The 2016 Credit Agreement provides for a $1.0 billion term loan facility (the 2016 Term Loan Facility) with a maturity date of April 28, 2023 and a revolving credit facility that may be established in the future (the 2016 Revolving Credit Facility, and together with the 2016 Term Loan Facility, the 2016 Credit Facilities). As of September 30, 2016, the aggregate outstanding principal amount under the 2016 Term Loan Facility was $1.0 billion.

The proceeds from the 2016 Term Loan Facility were used to repay approximately $588 million in remaining principal plus accrued and unpaid interest of the 2013 Citicorp Credit Facility Tranche B-2 with the remainder of the proceeds to be used for general corporate purposes.

The 2016 Term Loan Facility is repayable in annual installments in an amount equal to 1.00% of the original principal balance with any unpaid balance due on the maturity date of the 2016 Term Loan Facility. Voluntary prepayments may be made by American at any time, with a premium of 1.0% applicable to certain prepayments made prior to the date that is six months following April 29, 2016.

Loans under the 2016 Term Loan Facility bear interest at a base rate plus an applicable base rate margin or, at American’s option, LIBOR (subject to a floor of 0.75%) plus an applicable LIBOR margin. The applicable base rate margin is 1.75% and the applicable LIBOR margin is 2.75% for loans under the 2016 Term Loan Facility.

The obligations of American under the 2016 Credit Agreement are secured by liens on substantially all aircraft spare parts owned by American. American has the ability to add or release certain types of collateral, subject to certain conditions, at its discretion. The obligations of American under the 2016 Credit Facilities are guaranteed by AAG. American is required to maintain a certain minimum ratio of appraised value of the collateral to the outstanding loans under the 2016 Credit Facilities.

The 2016 Credit Facilities contain events of default customary for similar financings, including cross default to other material indebtedness. Upon the occurrence of an event of default, the outstanding obligations under the 2016 Credit Facilities may be accelerated and become due and payable immediately. In addition, if a “change of control” (as defined in the 2016 Credit Agreement) occurs with respect to AAG, American will (absent an amendment or waiver) be required to repay at par the loans outstanding under the 2016 Credit Facilities and terminate the 2016 Revolving Facility. The 2016 Credit Facilities also include covenants that, among other things, require AAG to maintain a minimum aggregate liquidity (as defined in the 2016 Credit Facilities) of not less than $2.0 billion, and limit the ability of AAG and its restricted subsidiaries to pay dividends and make certain other payments, make certain investments, incur liens on the collateral, dispose of the collateral, enter into certain affiliate transactions and engage in certain business activities, in each case subject to certain exceptions.

Obligations Associated with Special Facility Revenue Bonds

In June 2016, the New York Transportation Development Corporation (NYTDC) issued approximately $844 million of special facility revenue refunding bonds (the 2016 JFK Bonds) on behalf of American. The net proceeds from the 2016 JFK Bonds generally were used to provide a portion of the funds to refinance $1.0 billion of special facility revenue bonds (Prior JFK Bonds), the net proceeds of which partially financed the construction of a terminal used by American at John F. Kennedy International Airport (JFK) (the Terminal).

American is required to pay debt service on the 2016 JFK Bonds through payments under a loan agreement with NYTDC, and American and AAG guarantee the 2016 JFK Bonds. American’s and AAG’s obligations under these guarantees are secured by a mortgage on American’s lease of the Terminal and related property from the Port Authority of New York and New Jersey.

The 2016 JFK Bonds, in aggregate, were priced at approximately 107% of par value. The gross proceeds from the issuance of the 2016 JFK Bonds were approximately $907 million. Of this amount, approximately $895 million was used to partially fund the redemption of the Prior JFK Bonds. The 2016 JFK Bonds bear interest at 5.0% per annum and are comprised of $212 million of serial bonds, portions of which mature annually from August 1, 2017 to August 1, 2021, and $632 million of term bonds, $278 million of which matures on August 1, 2026 and $354 million of which matures on August 1, 2031. In connection with the refinancing of the Prior JFK Bonds, American recorded a special nonoperating charge of $36 million consisting of non-cash write offs of unamortized bond discounts and issuance costs as well as payments of redemption premiums and fees.

2014 Credit Facilities

On September 22, 2016, American and AAG amended the Amended and Restated Credit and Guaranty Agreement dated April 20, 2015 (which amended and restated the Credit and Guaranty Agreement dated October 10, 2014), pursuant to which it refinanced the $750 million term loan facility due October 2021 established thereunder (the 2014 Term Loan Facility and, together with the $1.025 billion revolving credit facility established under such agreement, the 2014 Credit Facilities) to reduce the LIBOR margin from 2.75% to 2.50% and the base rate margin from 1.75% to 1.50%. The $1.025 billion revolving credit facility under the 2014 Credit Facilities (the 2014 Revolving Facility) remains unchanged. As of September 30, 2016, $743 million of principal was outstanding under the 2014 Term Loan Facility and there were no borrowings or letters of credit outstanding under the 2014 Revolving Facility.

The federal NOL Carryforwards will expire beginning in 2022 if unused. We also had approximately $4.0 billion of NOL Carryforwards to reduce future state taxable income at December 31, 2015, which will expire in years 2016 through 2034 if unused. At December 31, 2015, we had an Alternative Minimum Tax credit carryforward of approximately $341 million available for federal income tax purposes, which is available for an indefinite period. In connection with the preparation of our financial statements for the fourth quarter of 2015, we determined that it was more likely than not that substantially all of our deferred tax assets, which include our NOLs, would be realized. Accordingly, we reversed $3.0 billion of the valuation allowance as of December 31, 2015. In the first nine months of 2016, we recorded income tax expense with an effective rate of approximately 38%, which is substantially non-cash as we utilized the NOLs described above. For purposes of taxation, substantially all of our income before income taxes is attributable to the United States. Following the filing of our 2015 annual tax return in the third quarter of 2016, federal NOLs, substantially all of which are expected to be available to reduce future federal taxable income in 2016 and future years, increased by $2.5 billion. The increase in the federal NOLs is attributable to the election to take bonus depreciation on eligible assets (primarily aircraft) in the 2015 federal income tax return.

Income Taxes	4. Income Taxes At December 31, 2015, American had approximately $8.8 billion of gross net operating losses (NOLs) carried over from prior taxable years (NOL Carryforwards) to reduce future federal taxable income, substantially all of which are expected to be available for use in 2016. American is a member of AAG’s consolidated federal and certain state income tax returns. The amount of federal NOL Carryforwards available in those returns is $8.0 billion, substantially all of which is expected to be available for use in 2016. The federal NOL Carryforwards will expire beginning in 2022 if unused. American also had approximately $3.7 billion of NOL Carryforwards to reduce future state taxable income at December 31, 2015, which will expire in years 2016 through 2034 if unused. At December 31, 2015, American had an Alternative Minimum Tax credit carryforward of approximately $458 million available for federal income tax purposes, which is available for an indefinite period. In connection with the preparation of American’s financial statements for the fourth quarter of 2015, management determined that it was more likely than not that substantially all of its deferred tax assets, which include its NOLs, would be realized. Accordingly, American reversed $3.5 billion of the valuation allowance as of December 31, 2015. In the first nine months of 2016, American recorded income tax expense with an effective rate of approximately 38%, which is substantially non-cash as American utilized the NOLs described above. For purposes of taxation, substantially all of American’s income before income taxes is attributable to the United States. Following the filing of AAG’s 2015 annual tax return in the third quarter of 2016, federal NOLs, substantially all of which are expected to be available to reduce future federal taxable income in 2016 and future years, increased by $2.4 billion. The increase in the federal NOLs is attributable to the election to take bonus depreciation on eligible assets (primarily aircraft) in the 2015 federal income tax return.

Fair Value Measurements

7. Fair Value Measurements

Assets Measured at Fair Value on a Recurring Basis

We utilize the market approach to measure fair value for 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 nine months ended September 30, 2016.

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


	Fair Value Measurements as of September 30, 2016

Total	$	7,009	$	1,013	$	5,996	$	—

⁽¹⁾	Unrealized gains or losses on short-term investments and restricted cash and short-term investments are recorded in accumulated other comprehensive loss at each measurement date.

⁽²⁾	All short-term investments are classified as available-for-sale and stated at fair value. Our short-term investments mature in one year or less except for $100 million of bank notes/certificates of deposit/time deposits and $230 million of corporate obligations.

There were no Level 1 to Level 2 transfers during the nine months ended September 30, 2016.

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 in the fair value hierarchy.

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


	September 30, 2016				December 31, 2015
	Carrying Value		Fair Value		Carrying Value		Fair Value
Long-term debt, including current maturities	$	23,343	$	24,486	$	20,561	$	21,111

Cash and Short-term Investments

Generally, fluctuations in foreign currencies, including devaluations, cannot be predicted by us and can significantly affect the value of our cash and short-term investments located outside the United States. These conditions, as well as any further delays, devaluations or imposition of more stringent repatriation restrictions, may materially adversely affect our business, results of operations and financial condition. See Part II, Item 1A. Risk Factors – “We operate a global business with international operations that are subject to economic and political instability and have been, and in the future may continue to be, adversely affected by numerous events, circumstances or government actions beyond our control” for additional discussion of this and other currency risks.

Legal Proceedings	9 Months Ended
Legal Proceedings	Sep. 30, 2016
Legal Proceedings	11. Legal Proceedings Chapter 11 Cases. On November 29, 2011, 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 Merger. Pursuant to rulings of the Bankruptcy Court, the Plan established 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 “Single-Dip” unsecured claims. As of September 30, 2016, there were approximately 25.2 million shares of AAG common stock remaining in the Disputed Claims Reserve. As disputed claims are resolved, the claimants will receive distributions of shares from the Disputed Claims Reserve on the same basis as if such distributions had been made on or about the Effective Date. However, we are not required to distribute additional shares above the limits contemplated by the Plan, even if the shares remaining for distribution are not sufficient to fully pay any additional allowed unsecured claims. To the extent that 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 as of the Effective Date. There is also pending in the Bankruptcy Court an adversary proceeding relating to an action brought by American to seek a determination that certain non-pension, postemployment benefits are not vested benefits and thus may be modified or terminated without liability to American. On April 18, 2014, the Bankruptcy Court granted American’s motion for summary judgment with respect to certain non-union employees, concluding that their benefits were not vested and could be terminated. The summary judgment motion was denied with respect to all other retirees. The Bankruptcy Court has not yet scheduled a trial on the merits concerning whether those retirees’ benefits are vested, and American cannot predict whether it will receive relief from obligations to provide benefits to any of those retirees. Our financial statements presently reflect these retirement programs without giving effect to any modification or termination of benefits that may ultimately be implemented based upon the outcome of this proceeding. DOJ Antitrust Civil Investigative Demand. In June 2015, we received a Civil Investigative Demand (CID) from the United States Department of Justice (DOJ) as part of an investigation into whether there have been illegal agreements or coordination of air passenger capacity. The CID seeks documents and other information from us, and other airlines have announced that they have received similar requests. We are cooperating fully with the DOJ investigation. In addition, subsequent to announcement of the delivery of CIDs by the DOJ, we, along with Delta Air Lines, Inc., Southwest Airlines Co., United Airlines, Inc. and, in the case of litigation filed in Canada, Air Canada, have been named as defendants in approximately 100 putative class action lawsuits alleging unlawful agreements with respect to air passenger capacity. The U.S. lawsuits were the subject of multiple motions to consolidate them in a single forum, and they have now been consolidated in the Federal District Court for the District of Columbia. The airline defendants have moved to dismiss all claims in the class actions. Both the DOJ investigation and these lawsuits are in their very early stages and we intend to defend the lawsuits vigorously. Private Party Antitrust Action. On July 2, 2013, a lawsuit captioned Carolyn Fjord, et al., v. US Airways Group, Inc., et al., was filed in the United States District Court for the Northern District of California. The complaint named as defendants US Airways Group and US Airways, and alleged that the effect of the Merger may be to substantially lessen competition or tend to create a monopoly in violation of Section 7 of the Clayton Antitrust Act. The relief sought in the complaint included an injunction against the Merger, or divestiture. On August 6, 2013, the plaintiffs re-filed their complaint in the Bankruptcy Court, adding AMR and American as defendants, and on October 2, 2013, dismissed the initial California action. On November 27, 2013, the Bankruptcy Court denied plaintiffs’ motion to preliminarily enjoin the Merger. On August 19, 2015, after three previous largely unsuccessful attempts to amend their complaint, plaintiffs filed a fourth motion for leave to file an amended and supplemental complaint to add a claim for damages and demand for jury trial, as well as claims similar to those in the putative class action lawsuits regarding air passenger capacity. Thereafter, plaintiffs filed a request with the Judicial Panel on Multidistrict Litigation (JPML) to consolidate the Fjord matter with the putative class action lawsuits. The JPML denied that request on October 15, 2015 and plaintiffs’ request for further relief from the JPML was denied on February 4, 2016. Accordingly, the parties will continue to litigate the matter in Bankruptcy Court; a jointly proposed schedule for the remainder of the case was submitted on September 7, 2016, which has not yet been accepted by the court. We believe this lawsuit is without merit and intend to vigorously defend against the allegations. DOJ Investigation Related to the United States Postal Service. In April 2015, the DOJ informed us of an inquiry regarding American’s 2009 and 2011 contracts with the United States Postal Service for the international transportation of mail by air. In October 2015, we received a CID from the DOJ seeking certain information relating to these contracts and the DOJ has also sought information concerning certain of the airlines that transport mail on a codeshare basis. The DOJ has indicated it is investigating potential violations of the False Claims Act or other statutes. We are cooperating fully with the DOJ investigation. 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. See Part II, Item 1A. Risk Factors – “We may be a party to litigation in the normal course of business or otherwise, which could affect our financial position and liquidity” for additional discussion.

Legal Proceedings	10. Legal Proceedings Chapter 11 Cases. On November 29, 2011, 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 Merger. Pursuant to rulings of the Bankruptcy Court, the Plan established 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 “Single-Dip” unsecured claims. As of September 30, 2016, there were approximately 25.2 million shares of AAG common stock remaining in the Disputed Claims Reserve. As disputed claims are resolved, the claimants will receive distributions of shares from the Disputed Claims Reserve on the same basis as if such distributions had been made on or about the Effective Date. However, American is not required to distribute additional shares above the limits contemplated by the Plan, even if the shares remaining for distribution are not sufficient to fully pay any additional allowed unsecured claims. To the extent that any of the reserved shares remain undistributed upon resolution of all remaining disputed claims, such shares will not be returned to AAG but rather will be distributed to former AMR stockholders as of the Effective Date. There is also pending in the Bankruptcy Court an adversary proceeding relating to an action brought by American to seek a determination that certain non-pension, postemployment benefits are not vested benefits and thus may be modified or terminated without liability to American. On April 18, 2014, the Bankruptcy Court granted American’s motion for summary judgment with respect to certain non-union employees, concluding that their benefits were not vested and could be terminated. The summary judgment motion was denied with respect to all other retirees. The Bankruptcy Court has not yet scheduled a trial on the merits concerning whether those retirees’ benefits are vested, and American cannot predict whether it will receive relief from obligations to provide benefits to any of those retirees. American’s financial statements presently reflect these retirement programs without giving effect to any modification or termination of benefits that may ultimately be implemented based upon the outcome of this proceeding. DOJ Antitrust Civil Investigative Demand. In June 2015, American received a Civil Investigative Demand (CID) from the United States Department of Justice (DOJ) as part of an investigation into whether there have been illegal agreements or coordination of air passenger capacity.

A portion of the proceeds received from the sale of the 2016-3 EETCs has been used to acquire Series AA and A equipment notes issued by American to the pass-through trusts and the balance of such proceeds is being held in escrow for the benefit of the holders of the 2016-3 EETCs until such time as American issues additional Series AA and A equipment notes to the pass-through trusts, which will purchase the notes with escrowed funds. These escrowed funds are not guaranteed by American and are not reported as debt on our condensed consolidated balance sheet because the proceeds held by the depository are not American’s assets. Series AA equipment notes bear interest at 3.00% per annum and Series A equipment notes bear interest at 3.25% per annum. Interest and principal payments on the equipment notes will be payable semi-annually in April and October of each year, with interest payments beginning in April 2017 and principal payments beginning in October 2017. The final payments on the Series AA and Series A equipment notes are due in October 2028. Dividend Declaration In October 2016, we announced that our Board of Directors had declared a $0.10 per share dividend for stockholders of record on November 7, 2016, and payable on November 21, 2016. Any future dividends that may be declared and paid from time to time will be subject to market and economic conditions, applicable legal requirements and other relevant factors. We are not obligated to continue a dividend for any fixed period, and payment of dividends may be suspended at any time at our discretion.

Basis of Presentation (Policies)	Sep. 30, 2016
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, 2015. 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. On December 9, 2013 (the Effective Date), AMR Merger Sub, Inc. merged with and into US Airways Group, Inc. (US Airways Group) (the Merger), with US Airways Group surviving as a wholly-owned subsidiary of AAG, a Delaware corporation (formerly known as AMR Corporation or AMR) following the Merger. On December 30, 2015, in order to simplify our internal corporate structure and as part of the integration efforts following the business combination of AAG and US Airways Group, AAG caused US Airways Group to be merged with and into AAG, with AAG as the surviving corporation, and, immediately thereafter, US Airways, Inc. (US Airways), a Delaware corporation and wholly-owned subsidiary of US Airways Group, merged with and into American, with American as the surviving corporation. As a result of the merger of US Airways and American, US Airways transferred all of its assets, liabilities and off-balance sheet commitments to American. For financial reporting purposes, this transaction constituted a transfer of assets between entities under common control and was accounted for at historical cost. 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, as well as pensions, retiree medical and other postretirement benefits.
Recent Accounting Pronouncements	*Recent Accounting Pronouncements* In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, “Revenue from Contracts with Customers (Topic 606).” ASU 2014-09 completes the joint effort by the FASB and International Accounting Standards Board (IASB) to improve financial reporting by creating common revenue recognition guidance for GAAP and International Financial Reporting Standards (IFRS). Subsequently, the FASB has issued several additional ASUs to clarify the implementation guidance on principal versus agent considerations, identifying performance obligations, assessing collectability, presentation of sales taxes and other similar taxes collected from customers, non-cash consideration, contract modifications and completed contracts at transition. These ASUs apply to all companies that enter into contracts with customers to transfer goods or services. These ASUs are effective for public entities for interim and annual reporting periods beginning after December 15, 2017. Early adoption is permitted, but not before interim and annual reporting periods beginning after December 15, 2016. Entities have the choice to apply these ASUs either retrospectively to each reporting period presented or by recognizing the cumulative effect of applying these standards at the date of initial application and not adjusting comparative information. We are currently evaluating the requirements of these standards and have not yet determined the impact on our condensed consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, “Leases (Topic 842).” ASU 2016-02 requires lessees to recognize a lease liability and a right-of-use asset on the balance sheet and aligns many of the underlying principles of the new lessor model with those in Accounting Standards Codification Topic 606, Revenue from Contracts with Customers. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the requirements of ASU 2016-02 and have not yet determined its impact on our condensed consolidated financial statements. In March 2016, the FASB issued ASU 2016-09, “Compensation – Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting.” ASU 2016-09 simplifies the accounting for share-based payment award transactions including the financial statement presentation of excess tax benefits and deficiencies, classification of awards as either equity or liabilities, accounting for forfeitures and classification on the statement of cash flows. ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, including interim periods within those fiscal years. Early adoption is permitted. We early adopted this standard during the second quarter of 2016. The adoption of this standard resulted in the recognition of $418 million of previously unrecognized excess tax benefits in deferred tax assets and an increase to retained earnings on the condensed consolidated balance sheet as of the beginning of the current year, and the recognition of $9 million of excess tax benefits to the income tax provision for the nine months ended September 30, 2016.

For financial reporting purposes, this transaction constituted a transfer of assets between entities under common control and is reflected in American’s condensed consolidated financial statements as though the transaction had occurred on December 9, 2013, when a subsidiary of AMR merged with and into US Airways Group, which represents the earliest date that American and US Airways were under common control. Thus, all periods presented in Part I, Item 1B of this Quarterly Report on Form 10-Q are comprised of the condensed consolidated financial data of American and US Airways. This transaction was accounted for in a manner similar to the pooling of interests method of accounting. Under this method, the carrying amount of net assets recognized in the balance sheets of each combining entity are carried forward to the balance sheet of the combined entity and no other assets or liabilities are recognized. 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.
