In 1927, airplane pioneer William Boeing founded his own airline, Boeing Air Transport, and began buying other airmail carriers, including Varney Air Lines. Within four years, Boeing's holdings grew to include airlines, airplane and parts manufacturing companies, and several airports. In 1929, Boeing merged his company with Pratt & Whitney to form United Aircraft and Transport Corporation (UATC). In March 1928, Boeing Air Transport, National Air Transport, Varney Airlines and Pacific Air Transport combine as United Air Lines, providing coast-to-coast passenger service and mail service. It took 27 hours to fly the route, one way.
