Having not flown AA since all of the new benefits came into play, can someone please answer the following:

Would A class on AA metal earn me 100% cabin bonus if booked under the BA codeshare? (AA first gains 50% cabin bonus - BA first gains 100% cabin bonus)

I am planning a trip that involves rather a lot of AA flying and I would obviously like to maximise the mileage earned.

Cheers,
B
