I think it's the best gig going right now if you don't mind working hard and the lack an airline route schedule/structure/big airplanes/terminal food/crazy economic cycles/TSA everyday/etc... If the crew bases come into effect, I think you'll see turnover drop to virtually nothing. Luckily we're growing, so you'll still move up the ranks. Even the 50 guys that complain about everything, everyday, everywhere, don't have plans to go anywhere anytime soon.
But you gotta have the ATP.
