Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidation	The Company consolidates financial statements of all entities in which the Company has a controlling financial interest, including the accounts of any Variable Interest Entity in which the Company has a controlling financial interest and for which it is the primary beneficiary. All material intercompany balances are eliminated in consolidation.
Basis of Accounting	The accompanying Consolidated Financial Statements have been prepared in accordance with Generally Accepted Accounting Principles in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements.
Flight equipment	Flight equipment Flight equipment under operating lease is stated at cost less accumulated depreciation. Purchases, major additions and modifications, and interest on deposits during the construction phase are capitalized. The Company generally depreciates passenger aircraft on a straight-line basis over a 25-year life from the date of manufacture to a 15% residual value. The Company generally depreciates freighter aircraft on a straight-line basis over a 35-year life from the date of manufacture to a 15% residual value. Changes in the assumption of useful lives or residual values for aircraft could have a significant impact on the Company’s results of operations and financial condition. Major aircraft improvements and modifications incurred during an off-lease period are capitalized and depreciated over the lesser of the remaining life of the flight equipment or the aircraft improvement. In addition, costs paid by us for scheduled maintenance and overhauls are capitalized and depreciated over a period to the next scheduled maintenance or overhaul event. Miscellaneous repairs are expensed when incurred. The Company’s management evaluates on a quarterly basis the need to perform an impairment test whenever facts or circumstances indicate a potential impairment has occurred. An assessment is performed whenever events or changes in circumstances indicate that the carrying amount of an aircraft may not be recoverable. Recoverability of an aircraft’s carrying amount is measured by comparing the carrying amount of the aircraft to future undiscounted net cash flows expected to be generated by the aircraft. The undiscounted cash flows consist of cash flows from currently contracted leases, future projected lease rates, and estimated residual or scrap values for each aircraft. We develop assumptions used in the recoverability analysis based on our knowledge of active lease contracts, current and future expectations of the global demand for a particular aircraft type, potential for alternative use of aircraft and historical experience in the aircraft leasing market and aviation industry, as well as information received from third-party industry sources. The factors considered in estimating the undiscounted cash flows are affected by changes in future periods due to changes in contracted lease rates, economic conditions, technology, and airline demand for a particular aircraft type. In the event that an aircraft does not meet the recoverability test and the aircraft's carrying amount falls below estimated values from third-party industry sources, the aircraft will be recorded at fair value in accordance with the Company’s Fair Value Policy, resulting in an impairment charge. Our Fair Value Policy is described below under “Fair Value Measurements”.
