This does not apply for BA flights but AA has a strict rule which doesn't allow cross-benefiting on their own flights.
Just curious... is this a BA-AA-only issue? Or [any OW carrier]-AA issue?

Also, is it ok to enter a BAEC number at booking (if the issue here is merely trying to change an AA FF# to a BAEC number after booking), whether or not one saves the reservation to his/her AAdvantage account?
