Back in 2003 when the last industry leading concessionary deal was pushed through I had discussed leaving the industry. I was asked not to by my wife as we had three kids and she asked that I wait till she finished school. She took six years but she finally did finish and she is an RN now (her starting pay was more than my maxed out pay). I was 42 years old then, looking back I'm not sure we made the right choice.
So here's the best answer I can give you at this point in time, none of that stuff really matters, this is a crappy place to work and its not going to get any better anytime soon. If there is one thing I've learned after 26 years at AA is waiting for things to get better simply does not pay off because things only get worse. Basically you are working as if you have no union, sure you pay dues but everything a Union normally provides is gone, in fact your deal is worse than what the non-union mechanics get.
Time to seriously start looking for another career. Moving to another carrier will only work if you are fortunate enough to see AA go out of businerss after you leave because how can UAL and other carriers continue to pay their guys $8/hr more than AA and compete? Even if the Wage Adjustment provision kicks in AA will still be paying at least three to four dollars an hour less when other forms of compensation, benefits and workrules are added in.
