The credit card of an upcoming guest was compromised. His bank issued him a new card. His reservation is with his old card and he wants to know how he can change the reservation to be booked on the new card instead. According to the information I could find he is not able to change the payment method on an active reservation. What would you recommend to rectify this situation? If he added the new credit card as an additional payment method, would Airbnb autmatically process the payment on that second card if the first is declined? Or should I tell him to cancel reservation and rebook with new card?
