Members who link more than one credit or debit card to their MileagePlus DiningSM account tend to earn more miles on average.
Why? Because with more linked cards, you’re less likely to use a card not associated with your MileagePlus Dining account and miss out on the chance to earn miles.
It’s a good idea to make a habit of updating your card information in your MileagePlus Dining account center any time you receive a new 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.
