Horizon Air, a regional airline based in SeaTac, Washington, serves 47 different destinations in the western United States, Canada and Mexico.
Horizon Air's inaugural destinations in 1981 were Pasco, Seattle, and Yakima, Washington which were served with two wet leased Fairchild F-27 turboprop aircraft.
[1] One year later, Horizon acquired Transwestern Airlines of Utah and then expanded into the intermountain West region of the United States.
[6] This change was brought mainly in part by the fleet transition plan, as the Bombardier Q200 plane that served Pendleton was phased out of service.
[4] Horizon Air launched its first Mexican route, flying a CRJ-700 between Loreto, Mexico and Los Angeles, California in January 2008.
