History Originally known as Kenyon Field, this aerodrome began passenger services in October 1938, but officially opened in June 1939. Prior to this, the city operated aviation activities in areas now occupied by Exhibition Park and Lethbridge Collegiate Institute. From 1939 to 1948, Lethbridge operated as western Canada's primary airline hub. According to the Trans-Canada Air Lines (TCA) system timetable dated January 1, 1940, Lethbridge was a stop on Trans-Canada's transcontinental flights linking Montreal, Ottawa, Winnipeg, Regina and Vancouver with connecting service to and from Toronto via North Bay (which was one of the stops on the TCA transcontinental flights between Montreal and Vancouver) operated with Lockheed piston engine twin prop aircraft. This same timetable also lists connecting TCA service between Lethbridge and Calgary and Edmonton.

Western operated Boeing 247D twin prop aircraft with a routing of Lethbridge-Cut Bank-Great Falls-Helena-Butte-Idaho Falls-Pocatello-Salt Lake City. According to the route map in the above referenced timetable, Lethbridge was the only international destination served by Western at this time.
