Hi,

I have booked AA flights, and originally input my BA frequent flyer number in as ideally I'd like to receive the miles into this account.

I have oneworld status, and therefore would like to use this to select some exit row seats, but it linked to my cathay pacific ff number.

Is there a way of temporarily changing this to the cathay number, selecting my desired seats, and then reverting to the BA ff number so that I receive the miles there?

Thanks.
