Not much information here but this is what we found on the internet.

Exec Express Inc. operating as Exec Express Commuter Airlines later became Exec Express II Inc. and eventually operated under the d/b/a of Lone Star Airlines and Aspen Mountain Air. In order to have both names on the same ticket stock a third d/b/a was created "Aspen Mountain Air/Lone Star Airlines"
