Trans-Canada Air Lines, now known as Air Canada, and Canadian Pacific Air Lines served Penticton after World War II. In 1956, the airport was granted a permanent license, replacing the temporary permit. The airport's runway was extended in 1959, and a new terminal was built in 1963. In 1968, Canadian Pacific Air Lines extended its services for the airport, scheduling two daily flights, only to be taken over by Pacific Western Airlines the following year. However, in 1988, Canadian Airlines ended this service. That was replaced by Time Air and Air BC airlines; both airlines are no longer active.
