I'm getting an Invalid AAdvantage number error message. I've had this number (one letter followed by 6 numbers) since the mid-1980's. It's the same number that shows when I log in at aa.com. What gives?
Edited to add: Yes, I'm a US member.
How very weird. I phoned AA and the CSR told me that he found my account with the same 6 numbers but a different first letter. When I log in and even when I use "forgot my AAdvantage number", the original correct account number is shown. Anyway I used the new incorrect first letter and the Facebook page accepted it.
