When you think sketchy, under the table 135, think GTA.
Plenty of 135 gigs in Dallas, or even just in Addison if that's what you want. Martinaire will take you with 135 mins. Ameristar or Cherry Air (though at least as sketchy as GTA) would probably stick you in the right seat of a Falcon with low time.
Over in Denton you have Alliance (Shorts and Falcons I think).
All pay more than GTA and won't have the stigma. Plenty of options.
