Does JAL have a concept of this?
I have never tested if you can change the frequent flyer number online on an award booking. But you could call JAL for the update. If it is for check in, lounge, and boarding, you can just show your card when needed. If it is for seat selection as well, you do need to get it updated to the AA number.
