SkyWest is the largest regional airline in the U.S., operating scheduled passenger service under the United Express, Delta Connection, American Eagle, and Alaska Airlines brands. Passengers buy tickets through the major airlines and typically don't know they're flying on a SkyWest aircraft. SkyWest operates roughly 2,260 daily departures across a fleet of about 487 aircraft — primarily Embraer E175s (~270 aircraft) and Bombardier CRJs (~217 aircraft). The bulk of SkyWest's revenue comes from capacity purchase agreements (CPAs) with its four major airline partners, under which the partners pay SkyWest fixed rates per flight and per block hour, and cover fuel costs directly. SkyWest bears operating costs like labor and maintenance, but is insulated from ticket price swings and fuel volatility. The remaining revenue comes from prorate agreements, where SkyWest shares fare revenue with partners and bears fuel costs — more volatile, but with more upside in strong demand environments. SkyWest's primary earnings driver is block hours flown; given the fixed-cost structure of the business, higher utilization translates directly into operating leverage. SkyWest also runs two smaller businesses: SkyWest Leasing, which leases surplus aircraft to third parties, and SkyWest Charter, a small on-demand charter operation using CRJ200s. SkyWest's growth strategy centers on expanding its E175 fleet toward ~300 aircraft by end of 2028, deploying CRJ550s under new United agreements, and growing its prorate flying in underserved communities.
