Segment Reporting |
Segment Reporting | (2) Segment Reporting GAAP requires disclosures related to components of a company for which separate financial information is available to, and regularly evaluated by, the Company’s chief operating decision maker when deciding how to allocate resources and in assessing performance. The Company’s two reportable segments consist of (1) the operations of SkyWest Airlines and SWC and (2) SkyWest Leasing activities. The Company’s chief operating decision maker analyzes the profitability of operating new aircraft financed through the issuance of debt, including the Company’s E175 fleet, separately from the profitability of the Company’s capital deployed for ownership and financing of such aircraft. The SkyWest Airlines and SWC segment includes revenue earned under the applicable capacity purchase agreements attributed to operating such aircraft and the respective operating costs, and revenue and operating expenses attributed to other flying or airport services agreements. The SkyWest Leasing segment includes applicable revenue earned under the applicable capacity purchase agreements attributed to the ownership of new aircraft acquired through the issuance of debt and the respective depreciation and interest expense of such aircraft. The SkyWest Leasing segment also includes the activity of leasing regional jet aircraft and spare engines to third parties and other activities. The SkyWest Leasing segment’s total assets and capital expenditures include new aircraft acquired through the issuance of debt and assets leased to third parties. Additionally, aircraft removed from SkyWest Airlines’ operations and held for sale are included in the SkyWest Leasing segment. The following represents the Company’s segment data for the years ended December 31, 2023, 2022, and 2021 (in thousands).
