Its been awhile since My Mesa Days!
I would drop in a Resume at everyone else first. If you have no call backs within 2-3 weeks, try your luck at Mesa. I did my time there and made the best of it. That was 10 years ago. My buddy is still there after 15 years and seems to be doing fine and is in the top 5% of the pilot group. Whats funny is that we make the same amount of income. He is checkairman in the EMB145/CRJ. and has a OK schedule. I on the other hand, I drive my Airbus and take major paycuts after 10yrs. Mesa has changed since I've been there but try your luck at some of the other ones first. Caution, do not expect much of a raise though. Good luck in your search.
