If it's AA metal and AA flight numbers, then yes. The "where you bought it" part doesn't matter as long as it's both operated and marketed by AA.
Cheers.
Thanks for the info. BA numbers show on the BA.com page for all flights whether on AA metal or not. However, at the end of this process I can get the AA record locator from BA. Why not book at AA.com? Burning a BA voucher.
