As someone who has had a real headache getting flights properly credited, the safest thing by far is to follow the advice above and log in to BA as a guest, although that may mean spending some time filling in some blanks, and credit the flight to your AAdvantage account in the first instance. Once your BAEC number is in the reservation, it is difficult to remove it, and methods I've used in the past successfully (using the AY website or having the agent at the airport change it) nowadays don't seem to work. A BA reservations agent on the phone should be able to do it, but you risk a long hold listing to that horrible music.
