When a guest books, their reservation is confirmed immediately. Sometimes guests want to make changes to their reservation later on.
If a guest contacts you to change their booking, tell them to do it through either their confirmation email or Booking.com profile. You can't make changes on their behalf.
You can only modify bookings (prices or dates) on or after the check-in date through the Reservations tab on the Extranet, by following these steps:
- Click the reservation number or room name.
- select an option from the menu on the right-hand side of the screen, under Update this reservation.
