Get it fixed before you check in, dolfinco. Even if things are running smoothly at the airport there's no guarantee that you will be able to find an agent with the time, patience and inclination to remove your AAdvantage number and enter your BAEC number.
Called them today to do this and the girl took all the details and said it was done. Just logged on to look at my booking and its still showing the AA number?
I know its a stupid question but will i need to call back or will it always show my AA number as thats what im logged into ?
My travel partners BA number is showing though she doesnt have an AA account.
