And don't forget that you (in all likelihood) get that bonus on partners. In general, the partner earnings with AA stink. The other major downer is the lack of earning/redemptions on BA TATL. AA is a great program, don't get me wrong, but for all its faults, I think that SM is better for earning across the alliance (at least for now).
