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. Unless otherwise noted, all amounts disclosed are stated before consideration of income taxes. 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, 2014 and September 30, 2013 are not necessarily indicative of operating results for the entire year. Recent Accounting Standards Revenue from Contracts with Customers In May 2014, the Financial Accounting Standards Board issued Accounting Standards Update No. 2014-09, "Revenue from Contracts with Customers." While the standard supersedes existing revenue recognition guidance, it closely aligns with current GAAP. Under the new standard, revenue is recognized at the time a good or service is transferred to a customer for the amount of consideration received for that specific good or service. It is effective for annual reporting periods beginning after December 15, 2016, including interim reporting periods, and early adoption is not permitted. Entities may use a full retrospective approach or report the cumulative effect as of the date of adoption. We are currently evaluating the impact, if any, the adoption of this standard will have on our Consolidated Financial Statements.
