Post Booking services allow users to shop and price Optional Services (or Ancillaries) such as Seats, Baggage and Meals for their bookings. This service allows customers to shop for free standard seats and paid seats. Paid Seats and other Optional Services are returned in the response if they are supported by the carrier in the submitted itinerary. The price of the Optional Service is also returned in the response.. Optional Services can be purchased post-booking, when available, for any carriers that are not Low Cost Carriers (LCCs).

In this section, you will learn about checking the availability of services, such as baggage or meals, and getting a seat list for selection. The endpoints involved in this process are:
