My aunt has the AAdvantage Aviator Red card, but she doesn't know how to actually access her AAdvantage account on AA.com. I used the form on AA.com to retrieve her AAdvantage account number, but it appears that form created her a duplicate AAdvantage account instead of retrieving her existing AAdvantage account.

She will be coming over here on June 7, and I was wondering if there is anything I can do to help merge the two accounts. I can check if the last digits of the AAdvantage account number on file with Barclays matches the account number that I recieved from AA, but if not, is there anything I can do to help her? Also, she has a hard time remembering passwords, so hopefully she remembers her username and password with Barclays.

EDIT: Alternatively, I can see if she has any miles with the account number I recieved from AA. It appears there are security questions that I never set, so maybe it isn't a duplicate after all. She would probably know the answers. The email though that she forwarded me appears like it is for a new account creation, rather than for an existing account.
