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, Toronto, Winnipeg and Vancouver. U.S. air carrier Western Air Lines served Lethbridge at this time as well with flights to Salt Lake City with connecting service to Las Vegas and Los Angeles. 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.
