In 1946, Ontario Municipal Airport was renamed "Ontario International Airport" because of the transpacific cargo flights originating there. On 17 May 1946, two Army surplus steel hangars arrived at the airport, which the Ontario city council had authorized the $50,000 purchase of just the previous week. City officials were pleased to have secured a bargain. Thought to be the only pair available in the U.S., City Manager Harold J. Martin observed that even if they could be acquired at a later date, the cost would be several times that afforded by prompt action. A Pacific Overseas Airlines flight from Shanghai arrived at Ontario on 18 May 1946, "which inaugurated regular round-trip air passenger air service between the United States and the orient." In 1949 Western Airlines began scheduled flights; in 1955 Bonanza Air Lines flights started. Western and Bonanza nonstops did not reach beyond Las Vegas. In 1962 Western began nonstop flights to San Francisco (one Electra daily). In 1967 Bonanza began nonstop F27 flights to Phoenix.
