SkyWest Airlines operates a regional carrier providing scheduled passenger flights throughout the United States, Canada, and Mexico, flying approximately 2,260 daily departures under code-share agreements with major carriers including United, Delta, American, and Alaska Airlines. The company operates a fleet of over 600 aircraft configured with 30–76 seats and generates revenue primarily through capacity purchase agreements with airline partners (who pay fixed fees per departure and flight hour while bearing fuel costs) and prorate agreements (where SkyWest shares ticket revenue and bears operating expenses). SkyWest also operates aircraft leasing and on-demand charter services, competing with other regional carriers on factors including labor availability, operating costs, on-time performance, and aircraft financing capability.
