Do you guys really feel this airline is doomed? I'm not a UA FF, but I'm fine with the OVERALL product now, I know I'm paying less, so I kinda know I won't get a TV etc, things like that. But while this "transition" is taking too long, I think the base is there to have a profitable and prosperous airline. They've got a bit of an aging fleet (just eyeballing it, don't know the exact figures), but they've got strong routes and a loyal customer following (which may be dwindling from the sounds of things).
I think they're perhaps behind the other majors right now, but not that far off from getting back to where they should be.
Though from everything I'm seeing, a leadership change is essential, I think the stock kinda rode the coat tails of the sector, but if it breaks away from the trend a bit and slips, you can bet the shareholders will demand a change and that's more powerful than any pilots/customers signing a petition or sending a strongly worded letter.
My 2 cents...
