Sales-Leaseback [Abstract]
Sale Leaseback Transactions [Text Block]	Sale-Leaseback Transaction In June 2020, the Company entered into a sale-leaseback transaction on four aircraft. The transaction qualified as a sale, and generated $48.0 million of proceeds. The aircraft were removed from the Company's balance sheet within property and equipment, resulting in a $30.2 million loss on sale. The loss is reflected within operating special charges on the statement of income since the Company would not likely have transacted absent cash conservation efforts as a result of COVID. The leased aircraft were subsequently recorded within operating lease right-of-use assets, with the related lease liabilities recorded within accrued liabilities and other noncurrent liabilities on the balance sheet. This transaction is treated as an cash inflow from investing activities on the statement of cash flows.
