If you put some miles in your BA account and some miles in your AA account, you have less flexibility than when you consolidate all your miles in a single programme (and will find it harder to achieve status).
I have both because of the 100,000 miles BA credit card offer. I signed up for the card and a BA account to get the miles. Flying with miles to London & Paris in Business class! Yay!
