Pacific Air Transport's main north-south airmail and passenger route continued in operation throughout 1927. However, Gorst did not make comfortable profits as the airmail loads were not as bulky as on some other CAM routes. He therefore sought the help of aviation entrepreneurs. Bill Boeing proved to be interested in the airline and his
Boeing Air Transport acquired control of PAT on 1 January 1928. This immediately provided a market for new aircraft as six four-passenger
Boeing 40Bs were supplied to the airline during 1928. On 17 December 1928, PAT merged into Boeing Air Transport, but continued to operate as a separate division, retaining its own identity. ==See also==
