Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Accounting [Policy Text Block]

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.

Refinery related buy/sell agreements [Policy Text Block]

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 below) 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.

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 10.
