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, 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. In accordance with the New Lease Standard, 2018 periods have been recast to reflect the effects of this adoption. As a result of the adoption of the New Lease Standard, our first quarter of 2018 net income decreased by $27 million . (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 of stranded tax effects principally related to our pension plans from accumulated other comprehensive loss to retained earnings.

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 three months ended March 31, 2019 , we repurchased 16.7 million shares of AAG common stock 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 March 31, 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 .

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 received preliminary approval from the DC Court on June 18, 2018. 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 United States Bankruptcy Court for the Southern District of New York. 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 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 on April 15, 2019 and closing arguments are scheduled to be heard on April 26, 2019. 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. 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.

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, 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.
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. As a result of the adoption, we reclassified $622 million of stranded tax effects principally related to our pension plans from accumulated other comprehensive loss to retained earnings.
