I think we'd have had far more uproar here on FT if any confirmed revenue F pax could simply displace any upgraded F pax during the slightest of IRROPS. As it stands, based on my understanding F pax who are IRROPS'd onto a flight that is full up front end up on the PALL list as DSR and therefore have highest priority for any F seat that becomes available.

Edit: my understanding above applies to pax who receive complimentary EXP/PRO or 500-mile upgrades, not those who have confirmed instrument upgrades, who AA treat (or should treat) as confirmed F pax for all intents and purposes.
