West Coast Airlines was a United States local service carrier, a scheduled airline certificated by the federal Civil Aeronautics Board (CAB), linking small cities in the Pacific Northwest with larger cities in Washington, Oregon, Idaho, Utah, Montana, California and north to Alberta in Canada.

[3][4][5][6] The company was based at Boeing Field in Seattle and began scheduled passenger service in 1946 with a fleet of Douglas DC-3s, marketed as Scenicliners.

In June 1968 West Coast was the first airline to order Fairchild 228 twin jets with the acquisition of three planned, but the F-228, a smaller variant of the Dutch manufactured Fokker F28 Fellowship, never made it to production.

San Francisco, Oakland, and Sacramento in northern California were added in 1959 with Salt Lake City being served later.

[12] A Canadian commuter airline with a similar name, West Coast Air, flew floatplanes between Vancouver and Victoria, British Columbia.
