Discontinued Operations And Disposal Groups [Abstract]
Assets Held for Sale	6. Assets Held for Sale During 2022, our management committed to a formal plan to sell certain of our CRJ-900, CRJ-200, and CRJ-700 aircraft. Accordingly, we determined the aircraft met the criteria to be classified as assets held for sale and have separately presented them in our condensed consolidated balance sheet at the lower of their current carrying value or their fair market value less costs to sell. The fair values are based upon observable and unobservable inputs, including recent purchase offers and market trends and conditions. The assumptions used to determine the fair value of our assets held for sale are subject to inherent uncertainty and could produce a wide range of outcomes which we will continue to monitor in future periods as new information becomes available. Prior to the ultimate sale of the assets, subsequent changes in our estimate of the fair value of our assets held for sale will be recorded as a gain or loss with a corresponding adjustment to the assets’ carrying value. As of March 31, 2023, the Company has 14 CRJ-900 aircraft and one (1) CRJ-200 aircraft that are classified as assets held for sale with a net book value of $40.5 million, which is reflected within assets held for sale on our condensed consolidated balance sheet. The Company closed the sale of eight (8) CRJ-700 aircraft in January 2023. The approximate net proceeds from the sale after retirement of debt was $8.0 million. The Company additionally closed the sale of four (4) CRJ-900 aircraft in March 2023. The proceeds of $12 million from the sale of the CRJ-900 aircraft were used to pay down the Company's obligations under its US Department of Treasury secured loan facility.
