I don't think you will much on here that would make you want to go to gojet. I was there and I never imagined that a company would ever treat people like they did. I won't go into details because others already have. I kind of feel like the only survivor of a platoon at the end of the war and will feel guilty about it the rest of my life. If you go there after finding out about it then you are a fool, which I hope you are not. I don't think TSA is much better. I have no opinion about Mesa.
Skywest has the best training in the industry and upgrade will be about 2 years which is pretty quick for most people who need to get some experience before going into the left seat. Skywest runs a quality outfit and they get pass privileges on Delta, United, American, and Alaska. Delta is the one you want. United flights are always overbooked so their pass privileges are worthless.
