Members who keep more than one credit and/or debit card linked and up-to-date in their AAdvantage DiningSM Account center tend to earn more American Airlines AAdvantage® miles.
Why? Because then you won’t mistakenly use a card not linked with AAdvantage DiningSM when dining out and miss out on rewards.
Make a practice of updating your card information in your AAdvantage DiningSM Account center any time a card issuer sends you a newly numbered credit or debit card.
If the card number remains the same, but the expiration date or security code changes, that’s no problem. We never ask our members to provide this information
