Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Consolidation and Presentation of Financial Statements Disclosure and Significant Accounting Policies [Text Block]	NOTE 1. 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. 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 six months ended June 30, 2012 are not necessarily indicative of operating results for the entire year. Recent Accounting Standards In June 2011, the Financial Accounting Standards Board issued "Presentation of Comprehensive Income." The standard revises the presentation and prominence of the items reported in other comprehensive income and is effective retrospectively for fiscal years beginning after December 15, 2011. We adopted this standard in the March 2012 quarter and have presented comprehensive income (loss) on our Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).
