$196 x 3 tickets bought MCO-PHL in early August. The upgrade offer is...wait for it... $1527 PER PERSON. ExpertFlyer shows J7 and a wide open seat map. The up-fare to go to true F(and earn LPs) would "only" cost $750.
AA really needs to fire whoever is designing the algorithm(s) that price these offers. It can't be that hard to do a check on what I paid versus what I could upfare for before making such an out of the stratosphere offer for a 2 hour domestic flight.
