As far as I'm concerned I purchased F and if AA isn't going to honor that and I have to fly Y, I'll make sure AA doesn't get a dime of the fare.
Some YUPs book into A, some into P. In irrops, there are usually weather issues so they often zero out all but F, and that's where the trouble arises. You also have problems if standing by, as I described, where more often than not in my experience you end up at the end of the upgrade queue, after all confirmed passengers have been upgraded.
