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, 2018 . 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, as well as pension and retiree medical and other postretirement benefits. In the fourth quarter of 2018, we adopted ASU 2016-02: Leases (Topic 842) (the New Lease Standard) as of January 1, 2018. The New Lease Standard did not require the recast of prior periods; however, since we elected to early adopt the New Lease Standard in the fourth quarter of 2018, the three and six months ended June 30, 2018 have been recast to reflect the effects of adoption. As a result of the adoption of the New Lease Standard, our three and six months ended June 30, 2018 net income decreased by $10 million and $37 million , respectively. (b) Recent Accounting Pronouncements ASU 2018-02: Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income This ASU provides the option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings due to the U.S. federal corporate income tax rate change as a result of H.R. 1, the 2017 Tax Cuts and Jobs Act (the 2017 Tax Act). The amount of the reclassification is the difference between the amount initially charged or credited directly to other comprehensive income at the previous U.S. federal corporate income tax rate that remains in accumulated other comprehensive income and the amount that would have been charged or credited directly to other comprehensive income using the newly enacted U.S. federal corporate income tax rate, excluding the effect of any valuation allowance previously charged to income from continuing operations. This standard is effective for interim and annual reporting periods beginning after December 15, 2018. In the first quarter of 2019, we adopted this standard retrospectively as of December 22, 2017, the date the 2017 Tax Act was enacted, which resulted in the recast of prior reporting periods. As a result of the adoption, we reclassified $622 million

Equity [Abstract]
Share Repurchase Programs and Dividends	Share Repurchase Programs and Dividends In April 2018, we announced that our Board of Directors authorized a $2.0 billion share repurchase program that will expire on December 31, 2020. Since July 2014, our Board of Directors has approved seven share repurchase programs aggregating $13.0 billion of authority. As of June 30, 2019 , there was $1.1 billion of remaining authority to repurchase shares under our current $2.0 billion share repurchase program. Share repurchases under our 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 that may be made from time to time will be subject to market and economic conditions, applicable legal requirements and other relevant factors. We are not obligated to repurchase any specific number of shares and our repurchase of AAG common stock may be limited, suspended or discontinued at any time at our discretion and without prior notice. During the six months ended June 30, 2019 , we repurchased 16.7 million shares of AAG common stock (all of which we purchased during the first quarter of 2019) for $600 million at a weighted average cost per share of $36.02 . Since the inception of our share repurchase programs in July 2014 through June 30, 2019 , we repurchased 295.6 million shares of AAG common stock for $11.9 billion at a weighted average cost per share of $40.43 . In April 2019 , our Board of Directors declared a cash dividend of $0.10 per share for stockholders of record as of May 8, 2019 and paid on May 22, 2019 , totaling $44 million . For the first six months of 2019 , we paid total quarterly cash dividends of $90 million .

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 one year . Accordingly, any revenue associated with tickets sold for future travel will be recognized within twelve months. For the six months ended June 30, 2019 , $3.1 billion of revenue was recognized in passenger revenue that was included in our air traffic liability at December 31, 2018 .

All of the proceeds received by such pass-through trusts from the sale of the 2019-1 Engine EETCs have been used to acquire equipment notes issued by American to the pass-through trusts. The pass-through trust certificates represent the right to payment under the equipment notes that are full-recourse obligations of American and such equipment notes are secured by spare aircraft engines currently owned and operated by American. Equipment Notes Issued in 2019 In the first six months of 2019 , American entered into agreements under which it borrowed $1.1 billion in connection with the financing or refinancing, as the case may be, of certain aircraft, of which $464 million was used to repay existing indebtedness. Debt incurred under these agreements matures in 2024 through 2031 and bears interest at variable rates (comprised of LIBOR plus an applicable margin) averaging 3.86 % at June 30, 2019 . 5.000% Senior Notes In May 2019, AAG issued $750 million aggregate principal amount of 5.000% senior notes due 2022 (the 5.000% senior notes). These notes bear interest at a rate of 5.000% per annum, payable semi-annually in arrears on June 1 and December 1 of each year, beginning on December 1, 2019. The 5.000% senior notes are senior unsecured obligations of AAG. The 5.000% senior notes mature on June 1, 2022 and are fully and unconditionally guaranteed by American. The indenture for the 5.000% senior notes contains covenants and events of default generally customary for similar financings. In addition, if AAG experiences a specified change of control, AAG must offer to repurchase the 5.000% senior notes in whole or in part at a repurchase price of 101% of the aggregate principal amount plus accrued and unpaid interest, if any, to (but not including) the repurchase date. Upon the occurrence of certain events of default, the 5.000% senior notes may be accelerated and become due and payable immediately.

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 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 purposes of calculating earnings per common share. As disputed claims are resolved, the claimants will receive distributions of shares from the Disputed Claims Reserve. However, 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. 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 and former convertible noteholders treated as stockholders under the Plan. On February 12, 2019, in accordance with the approval granted by the Bankruptcy Court on December 6, 2018, an aggregate of approximately 17.3 million shares of AAG common stock were distributed from the Disputed Claims Reserve to former AMR shareholders and convertible noteholders. After giving effect to this distribution, the Disputed Claims Reserve holds approximately 7 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, 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 have been consolidated in the Federal District Court for the District of Columbia (the DC Court). On June 15, 2018, we reached a preliminary settlement agreement with the plaintiffs in the amount of $45 million that, once approved, will resolve all class claims in the U.S. lawsuits. That settlement was approved by the DC Court on May 13, 2019. 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. The parties submitted proposed findings of fact and conclusions of law and made closing arguments in April 2019, and we are awaiting the Bankruptcy Court's decision. 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 Department of Justice (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 Civil Investigative Demand 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 with regard to its 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.

Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU 2018-02: Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income This ASU provides the option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings due to the U.S. federal corporate income tax rate change as a result of H.R. 1, the 2017 Tax Cuts and Jobs Act (the 2017 Tax Act). The amount of the reclassification is the difference between the amount initially charged or credited directly to other comprehensive income at the previous U.S. federal corporate income tax rate that remains in accumulated other comprehensive income and the amount that would have been charged or credited directly to other comprehensive income using the newly enacted U.S. federal corporate income tax rate, excluding the effect of any valuation allowance previously charged to income from continuing operations. This standard is effective for interim and annual reporting periods beginning after December 15, 2018. In the first quarter of 2019, we adopted this standard retrospectively as of December 22, 2017, the date the 2017 Tax Act was enacted, which resulted in the recast of prior reporting periods.

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 pension and retiree medical and other postretirement benefits.
Recent Accounting Pronouncements	Recent Accounting Pronouncements ASU 2018-02: Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income This ASU provides the option to reclassify stranded tax effects within accumulated other comprehensive income to retained earnings due to the U.S. federal corporate income tax rate change as a result of H.R. 1, the 2017 Tax Cuts and Jobs Act (the 2017 Tax Act). The amount of the reclassification is the difference between the amount initially charged or credited directly to other comprehensive income at the previous U.S. federal corporate income tax rate that remains in accumulated other comprehensive income and the amount that would have been charged or credited directly to other comprehensive income using the newly enacted U.S. federal corporate income tax rate, excluding the effect of any valuation allowance previously charged to income from continuing operations. This standard is effective for interim and annual reporting periods beginning after December 15, 2018. In the first quarter of 2019, American adopted this standard retrospectively as of December 22, 2017, the date the 2017 Tax Act was enacted, which resulted in the recast of prior reporting periods. As a result of the adoption, American reclassified $622 million
