Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying unaudited Condensed Consolidated Financial Statements include the accounts of Delta Air Lines, Inc. and our wholly-owned subsidiaries. These financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) for interim financial information. Consistent with these requirements, this Form 10-Q does not include all the information required by GAAP for complete financial statements. As a result, this Form 10-Q should be read in conjunction with the Consolidated Financial Statements and accompanying Notes in our Form 10-K. We reclassified certain prior period amounts, none of which were material individually or in total, to conform to the current period presentation. Management believes the accompanying unaudited Condensed Consolidated Financial Statements reflect all adjustments, including normal recurring items and restructuring and other items, considered necessary for a fair statement of results for the interim periods presented. Due to seasonal variations in the demand for air travel, the volatility of aircraft fuel prices, changes in global economic conditions and other factors, operating results for the three and nine months ended September 30, 2013 are not necessarily indicative of operating results for the entire year. As described in Note 13, we became the sole owner of Endeavor Air, Inc. ("Endeavor"), formerly Pinnacle Airlines, Inc., on May 1, 2013, pursuant to a confirmed plan of reorganization in the bankruptcy cases of Endeavor and its affiliates. Prior to this acquisition, Endeavor served as a Delta Connection carrier under a capacity purchase agreement where we purchased all of Endeavor's seat inventory and marketed it under the Delta tradename. Accordingly, Endeavor's passenger revenue was included in regional carriers passenger revenue in Delta's Consolidated Statements of Operations and Comprehensive Income. All of the expenses Delta incurred under this arrangement were included in contract carrier arrangements expense. Subsequent to this acquisition, we have maintained this presentation and have re-titled contract carrier arrangements expense as regional carrier expense to reflect the inclusion of a wholly-owned regional carrier. This presentation aligns with the regional revenue presentation on the Consolidated Statements of Operations and Comprehensive Income. Accounting for Refinery Related Buy/Sell Agreements To the extent that we receive jet fuel for non-jet fuel products (as defined in Note 2) exchanged under buy/sell agreements, we account for these transactions as non-monetary exchanges. We have recorded these non-monetary exchanges at the carrying amount of the non-jet fuel products transferred within aircraft fuel and related taxes on the Consolidated Statement of Operations and Comprehensive Income. Recent Accounting Standards Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income Recently issued accounting guidance revises the reporting of items reclassified out of accumulated other comprehensive income and is effective for fiscal years beginning after December 15, 2012. We adopted this guidance in the March 2013 quarter and have presented amounts reclassified out of accumulated other comprehensive income in a note to the financial statements. For more information about accumulated other comprehensive income (loss), see Note 11.
