According to the
FAQs (at least for AA), the 5 card limit remains in effect:
Q. How do I register additional credit/debit cards?
A. You can add or change credit and debit cards, and update any of your other personal membership information by visiting your "My Account Center" located on the Web site. You can register up to 5 credit/debit cards in total.
However, I currently have 9 cards registered with AA RN and have been getting points for recent dines. So, perhaps the limit is not generally enforced?
