The first Western Air Express flight departed #onthisday in 1926 with an airmail flight from Los Angeles to Salt Lake City in a Douglas M-2 mailplane. Within a year, the young airline was responsible for delivering 40% of the volume of the nation's airmail on its Los Angeles mail service. A merger in 1930 between TAT (Transcontinental Air Transport) and Western Air Express formed TWA, Transcontinental & Western Air (later Trans World Airlines).
