Go there and click on the one you want to check or add a card to. If you have a card synced to Twitter for example, it will tell you the last four digits and ask if you mean to change it? If no just exit out and now you know which card is synced...unless you have multiple cards with similar numbers.

My experience so far is mixed...two successes at getting the credit and one fail so far...escalated. Travelocity can post the bill as OnlineHotelRes and not Travelocity even though you bought on Travelocity. This confused Amex.
