Horizon Air's first route was from Yakima to Seattle, and one week later, Pasco to Seattle.[9] The general offices of Horizon Air were operated out of an old house behind Sea-Tac airport. Horizon acquired Air Oregon on June 17, 1982, after both airlines were losing hundreds of thousands of dollars monthly, in order to consolidate and reduce their operating deficit.[10] Horizon agreed to purchase Transwestern Airlines of Utah in September 1983, once again to try to reduce operating deficit of the airline.[11] A single Fokker F28 was the first jet owned by Horizon Air, purchased from a carrier in Africa, in July 1984, however their first jet was a wet leased Douglas DC-9.[12][13]
