Sort of, but back when I started flight school a lot of regionals required you to pay up front to play. I believe Comair required you to show up to class with a check for 10k at one point? (correct me if I'm wrong) I just heard of this while doing my PPL then, and Comair was the considered to be the "best" regional. Chautauqua (my current employer) required you to show up to training with a check also, then they switched to docking 200 bucks per pay check for like 6 years til it went away completely. Heck, even FLX was pay to play to fly a 210 at one point. Ill admit that was all before time as a Comm pilot. Gulfstream/Silver was the last to go away AFAIK.
Now guys are pissed because the bonus's aren't big enough. Just sayin'
