AMRCostunit,
The day may come you have a shot. However, I've worked with several guys and know a few more that QUIT FDX to return to other carriers (worst story...a 2000 return to UsAir).
This is another example of paying bills on costs you did not charge. You didn't quit, but your predecessors did. I know being "guilty by association" stinks but its a fact of life here right now.
What will change this? IMHO, it will take 2 factors. First, the available pool of guys from the regionals and military who are "untainted" with line numbers at other carriers will have to be exhausted. Second, a bunch of very influential ACPs, LCAs, or company types with close relatives or friends in your situation will have to lobby to make the change.
Nobody can predict the future of "fix" the past, but there is a lesson in this. I'm as much of a "take care of #1" guy as anyone, you have to know there is a "down the road" consequence for someone when you make some decisions. This is a classic example...
