During the 1960s the local service airlines of the United States were growing fast. Not only were they re-equipping their fleets but they were being assigned large numbers of routes by the CAB that had been discarded by the larger airlines. Meanwhile Boeing, Douglas and BAC were keen to sell as many of their new short-haul jets as possible. Boeing even managed to interest several airlines in its medium sized 727 and one of these was Frontier. Like most of the local service airlines however the 727 was still too much jet for their 1960s network.
