They further screwed it up at the airport putting Mom's EXP# on Jr.'s BP. When I asked them to fix it, they said that since the stickers came from the mother's account her number had to go on it. (Hogwash, of course). Next day fixing it with the EXP desk they confirmed that of course SDQ was nuts and his own number should have been there, that they would fix it, and both their records were annotated to the effect that no, the mother isn't trying to pull a fast one and collect miles from another's flying.
Additionally they confirmed that since stickers were to be used that that could only be done at the airport and not even at an AA ticket office.
Why can't that just be automated when there are no additional complications?
