Not every airline out there is AA or United there are countless number of shady startups that have failed, while some have succeeded like WN for example and along with them are pilots who were associated with these airlines. The fact is that not everyone can go from 0 to hero, you need to get experience. No one cares how you get to the top. For someone it's Colgan, for another it's EAgle, for another it's Mesa, and another it's GJ. As long as you have never crossed a line and kept your nose clean there is no reason care about how you're getting your flying. And after all this there are still people out there who think GJ is a "scab" airline then you're either dumb or have no idea, or both.
