You must always have at least one bank account linked to your AAdvantage® Debit Card. If you want to unlink your existing account, you need to link a new one first.
To do this, log in on the AAdvantage® Debit Card app and select your Account Icon in the top left, and then “Linked accounts”. Then select the new bank you want to link. Once your new account is linked you can remove the old one.
If you already have two linked accounts, you can press “Unlink” to remove one of them.
How do I unlink a bank account from my AAdvantage® Debit Card?
