Members who keep more than one credit and/or debit card linked and up to date in their SkyMiles® Dining Account Center tend on average to earn more miles.
Why? Because then you won’t mistakenly use a card not linked with SkyMiles Dining when dining out and miss out on miles.
Make a practice of updating your card information in your SkyMiles Dining Account Center any time a card issuer sends you a newly numbered 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.)
