...why would...
Anyways from my own experience since... lets say the past 10 months (the time I've been with my company) I have had coworkers get class dates at Republic, Mesa, Piedmont, Commutair, Expressjet, and Air Wisconsin. We are not a 121 company and the only two guys who had previous 121 experience interviewed at Commutair and Piedmont. Away from my job I've had two friends who as flight instructors, in the past year get hired at Trans States. Basically, as it appears to me at least, it doesn't matter at this point for the most part where your time comes from, it just has to meet the minimums. Yes places like Compass and Skywest will have their pick of the litter but everyone else... dunno how they have that luxury. Update your airline apps stuff and you'll be surprised who will call you at this point.
