Changing a reservation through Airbnb
Guests can change a reservation by going to “Your Trips” on Airbnb.com and clicking “Change Reservation” next to the reservation they want to change. You, the host, will then need to accept their request.
It's recommended that you ask your guests to send the change request. Altering it on your end may cause issues with the reservation.
Some booking information (i.e. number of guests) is locked until the reservation is accepted - even Airbnb can't update this information if the reservation is pending. Be sure that you and the guest have agreed upon the changes (documented in messages), accept the reservation, and then they can update accordingly.
