Rebooking an existing hotel PNR for price optimization

Hotel prices tend to change often based on demand and various other factors such as competitor pricing, market conditions, festival/holiday seasons, and so on. Some hotels provide the option to rebook their existing PNR if the original price of the hotel has changed.

For example, a traveler may consider rebooking an existing PNR after noticing a drop in price for the room they already booked. Some hotels provide the option to rebook a PNR (so that travelers can get better prices for their stay).

Note: The rebooking workflow will cancel the existing booking and create a new PNR with the same hotel preferences as the canceled one.

The steps below explain how to rebook an existing PNR for price optimization.
