Members who keep more than one credit or debit card registered and up-to-date in their MileagePlus DiningSM Account Center tend on average to earn more MileagePlus® award miles.
Why? Because then you won’t mistakenly use a card not registered with MileagePlus Dining when dining out and miss out on rewards.
Make a practice of updating your card information in your MileagePlus Dining 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.)
