There are a few reasons why a credit or debit card you linked isn’t appearing in your MileagePlus DiningSM Account Center. These include:
- You didn’t enter the full card number of the card in question before clicking “Link card.”
- You didn’t click the check box agreeing to the MileagePlus Dining Terms and Conditions.
- Your card is one of the few not accepted by MileagePlus Dining, including Diner’s Club and internationally-issued JBL cards.
- The card number was entered incorrectly or isn’t valid.
