Just had my domestic boarding pass reprinted at PHL because the one issued back in Munich had some bar code issues and wouldn't scan. Asked the US agent to add me to the upgrade list as an AA elite and she mentioned that the comped upgrade program is being eliminated and I'll need to support my upgrades in the future. As no one else has posted anything of the sort, I'm thinking the agent may not be up on the differences between AA and US upgrades yet. Time will tell.
