Sun Aire Lines

Sun Aire Lines was founded as Borrego Springs Airlines in 1968. Its operations initially focused on providing air service into Borrego Springs, California via the Borrego Valley Airport from other destinations in southern California such as San Diego and Palm Springs. The airline later moved its headquarters to Palm Springs, California. Borrego Springs Airlines operated a small fleet of Cessna 402 prop aircraft and Swearingen Metro II turboprops before changing its name to Sun Aire in 1975. Its primary destinations were Palm Springs, San Diego, Los Angeles, Borrego Springs, Phoenix, Yuma, Santa Barbara and Santa Maria. By 1984, the airline was operating a dozen Metro II propjet aircraft and was purchased by SkyWest Airlines. The airline operated its final service on September 28, 1985, at which time it was merged into SkyWest.
