AA booking but crediting BA
Hi all - I am losing my AA Platinum on 1/31, but I have BA EC Gold (which is OWE). I was hoping to credit the ticket I purchased through my travel agent to BA, but somehow I see my AA # in the booking.
2 questions if I may:
1. How do I change the FF# because there is no option on the AA website? In the past, I have asked at the gate, and sometimes they get credited to BA, other times it stays with AA.
2. If I change to BA#, would I still be able to get upgraded to First on domestic segments? BTW, I will retain AA Gold after 1/31 and I have plenty of 500-miles upgrades.
Appreciate your comments and assistance please. Thanks!
