I don't know how accurate one job jump will effect your resume. Personally, I now miss my GA job.

What I did was go to Piedmont, got my 121 training, spend all of about 45 days on the line after IOE, and got hired by one of my top three (ExpressJet). I must say, I had a tough time getting an airline interview before I went to Piedmont. Once I passed my 121 training, I got three calls from other airlines.

My point is this. If you really want ot fly shiny jets, go to Mesa and only plan on staying the 12 months. Do your research, and figure out your top three or five regionals and get your apps to them AS SOON AS YOU PASS IOE. Save your money in case one of them hires you, and you can pay off your contract. Believe me, the other regionals know which airlines out there people use as stepping stones. Mesa is definitely one of them! As long as you make it clear that whom ever you are jumping to from mesa knows that you want to make a career with them, you shouldn't have any issues.

I know several guys at Express Jet that have done the same thing at other various airlines. I'm sure Mesa would not approve of my post, but you know where they can put it.
