Chaparral Airlines - July, 1984

Chaparral Airlines' planes wound up eventually painted in American Eagle's livery, as per this account of the Eagle's growth at DFW:

The ‘80s marked American’s massive “Growth Plan” which added dozens of new markets and by design, new hubs. DFW was by far the largest and most logical place to start the foundation of an Eagle operation. In the summer of 1984, Senior Vice President of Marketing Thomas Plaskett, who later went on to become President of Pan Am, made the official announcement that Metroflight and Chaparral Airlines would be the “first two” of American’s Eagle network.

Chaparral joined with its Gulfstream 1Cs, CASA 212s and Beech 99s, and by year’s end, 60 daily flights were serving eight cities from DFW. The carriers adopted AA ticket stock, flight numbers, and a new AA-inspired livery.
