Stol Air Commuter was a United States commuter airline that began service around 1974. The air carrier was also known as STOL Air Commuter thus reflecting its use of STOL (short take-off and landing) aircraft. It served the San Francisco, California Bay Area, and northern California. The airline was based in San Rafael in Marin County north of the city of San Francisco and also had administrative offices located in Santa Rosa, CA at one point. Stol Air Commuter operated scheduled passenger air service connecting several cities in the San Francisco Bay Area as well as northern California with San Francisco International Airport (SFO). According to the airline's system timetable, in the spring of 1975 Stol Air Commuter was operating 66 daily flights serving SFO via United Airlines gate 10 at the airport.[1]
In 1979, Stol Air changed its name to WestAir Commuter Airlines.[2] WestAir subsequently became a United Express carrier operating turboprop and jet aircraft on behalf of United Airlines via a code sharing agreement.
