According to Advantage rules you will not earn miles for BA transatlantic flights. I have no experience with this so cant tell you if in pratice that is the case. You can earn miles for all other BA flights. From the AA website:
"Transatlantic flights do not accrue AAdvantage miles."
Here is the link which seems to be chopped in two so you will have to cut and paste unless someone can tell me how to fix it:
