Mid-West Airlines was a Des Moines, Iowa-based local service carrier, a scheduled airline certificated by the Civil Aeronautics Board (CAB), the now-defunct Federal agency that at the time tightly regulated almost all US air transportation, to fly smaller routes in Iowa, Minnesota, Nebraska, and South Dakota.
It was briefly owned by a Purdue University affiliate before being liquidated after the CAB refused to extend the airline's initial certification.
PAC briefly operated CAB-certificated scheduled service in 1949–1950, and from 1953 onward held CAB charter flight certification, ultimately acquiring airliner-class aircraft such as Douglas DC-3s and DC-6s.
[9] However, in April 1952, less than six months after permitting PRF to buy Mid-West, the CAB voted to decline to renew the certificate of the airline, forcing it to liquidate.
A second reason was that upgraded Mid-West service would provide direct competition to United Airlines on some routes, which was held to be undesirable.
