For the first nine years of transcontinental
airline service, 1939-1948, Lethbridge was western Canada's principal airline hub. The city was ideally situated to fulfill this function due to its location on the southerly route of the Trans-Canada Airway and the limited operational ceiling of the unpressurized Lockeed aircraft then in use.
