my buddy flies the atr out of san juan and he is happy there. upgrade at its shortest is going to be 3-4 yrs down the road and its currently in the ballpark of 7. they are desperate for pilots like almost every regional right now. you would make more at another regional with a shorter upgrade to captain. you also do have the potential for American to spread the regional feed to other carriers in the future kind of what continental did or is doing to expressjet. Nothing definitive yet or in the next couple months. I think American was "reviewing their regional contracts" or some BS like that. seems to be a sweet deal with the predetermined bases.
