I think a lot of people are going to be surprised how many "senior" AE Pilots DON'T choose to flow through. While I question that choice long term, it IS their choice. Given that, I'm afraid that AE is going to be a rather "senior" and rather "junior" company with not much in the middle. It may still work out, but I suspect AMR has a pretty good idea how...
Every AE pilot will need to read the final contract language to make up their own minds. I hope that they take a look at it based on 1) What's good for they and their families; 2) what's good for the AE pilots who stay long term; and 3) what's good for the profession. We do have a responsibility to leave this "career" better than we found it.
