Both are considered kind of crappy places to work. Mesa pays 1/2 time for deadhead and pays for some cancelations, but not all.

Pinnacle has issues with the NWA bankruptcy and possible loss of aircraft (NWA is creating their OWN regional to compete with PIN and Mesaba).

If you're making a decision between the two, research the NWA CH.11 situation, I believe PIN may be hiring to replace FO's who are leaving for other airlines (because they fear a furlough). Also consider geography...a little geographic advantage levels the playing field between any two regionals real quick. You are MUCH better off living in a junior domicile at a crappy regional than commuting 2000+ miles for a better regional. Arguing about quality of regionals is kind of like two hookers arguing about their relative virginity...
