The original Golden West Airlines, headquartered at Van Nuys, California, was founded in 1968 and operated out of Terminal 4 at Los Angeles International Airport with a fleet of de Havilland Canada DHC-6 Twin Otter STOL capable turboprops and at least one HFB 320 Hansa Jet aircraft, serving Pomona, Riverside, Santa Ana, and Ventura.
By 1968 service had expanded to include Apple Valley, Bakersfield, El Monte, Ontario, Oceanside, Palm Springs, Palmdale, San Diego, and Santa Ana.
In 1969, it merged with Skymark Airlines (a Sacramento-based charter and commuter airline founded in February 1968 that also operated the DHC-6 Twin Otter) and Cable Commuter Airlines (an Upland general aviation concern based at Cable Airport that had entered the scheduled commuter airline business in 1968 via a hub at Los Angeles International Airport (LAX) with flights to such southern California destinations to Burbank, Colton, Inyokern, Ontario, Oxnard, Palmdale, Palm Springs, Santa Ana (Orange County Airport), Santa Barbara and Santa Maria as well as service to Lake Havasu City in Arizona with all flights operated with DHC-6 Twin Otter aircraft).
[4] Because of California's growth and tourist appeal, Golden West was able to become an interline partner with a number of domestic and international airlines.
[5] By the early 1980s, Golden West was the largest commuter airline in California operating a high frequency shuttle schedule between LAX and Santa Barbara and San Diego.
In 1981, Golden West was the only air carrier flying nonstop between Santa Barbara and LAX with up to fourteen round trip flights a day.
