Anyone can get hired anywhere at any time it doesn't matter what your qualifications are. Apply, study, work hard and get to know people. Let the airline make the decision about you don't do their job for them.

And to answer the question of the original poster if you are flying lears and challengers why even consider the regionals? Spirt is hiring like crazy and Jet Blue sounds like they are in bad shape. Save yourself the pain and heartache and skip the regionals.

Unless you are out of a job then that is a different story. In such a case I would say Skywest or Compass are the least likely to give you a stroke.
