If you are looking to upgrade in 4+ years, work for a company that will live or die by it's own decisions, fly nice airplanes, etc...you will enjoy working for the company. I made a little over 150k last year(8 yr 717Ca) for you "lateral move" regional guys/gals.
Say what you will, this company will not invest in anything that does not get a return. They are not tied to a "mainline" anything. If you don't like to fly, look some where else. Show at the interview knowing we wear hats, push wheelchairs, pull tickets and fetch strollers, program the FMS and even -gasp- as a captain- do a walk around if it will help move things along. To base a decision soley on how contract talks are going is short sighted in my opinion. If this stuff makes you queasy you will hate it at AirTran.
Go with your gut. High cost structure airlines have always had great success. You should have no trouble finding one.
For me, I could not sign up again fast enough.
SHORT SIGHTED??? No, I've worked for two airlines where management has not cared about it's employee groups and this TA tells me that working for AirTran could be the third. And please don't make an inference that *gasp* I would have to work hard there. Working hard is all I know...
