All Seat Map requests allow you to request seat maps for any of the following:

To book a seat, you next send a Seat Book request as part of a workbench session.

To add ancillaries or seats to a multi-offer booking, send the Ancillary Shop or Seat Map request, then send one book request for each offer, in any order. Supported in the initial booking workflow only for free seats; supported for an existing booking for both ancillaries and seats. GDS

Response

The seat map response is similar for all Seat Map requests, regardless of where sent in the workflow. Exceptions:

When sent before creating the booking, TravelerIdentifierRef returns only the PTC Passenger Type Code, used to categorize travelers. The most common PTCs are adult (ADT), child (CNN), and infant (INF). You can request a maximum of 9 passengers in one Search request., as there are no traveler details at this point in the workflow.

These will be held while modifying seats until the new seat book request is confirmed at commit API call that ends a workbench session, finalizing all changes and requests in that session. Depending on the workbench transactions, the commit workbench request may create a reservation, issue a ticket or EMD, exchange tickets, or modify a reservation..

Example Response

The seat map response is nearly identical whether the request was sent after Search, after AirPrice, or in a workbench session. The only difference is that outside a workbench session, TravelerIdentifierRef returns only passengerTypeCode, as there are no traveler details at this point in the workflow. For brevity, all instances of Row after the first two rows have been edited out.

The following seat map response for NDC (CatalogOffering/Identifier/authority returns a carrier code instead of the value Travelport) returns both free seats (price of 0) and paid seats (price of 60), each in a separate instance of CatalogOffering. For brevity, all instances of Row after the first two rows have been edited out.

When Seat Map is sent for flight/s in a booking that already have seat assignments, the response inlcudes HeldAncillary to list the current SeatAssignment for each traveler on the flight/s. This supports modifying seats by holding the current seats until the new seats are successfully booked at workbench commit, ensuring those seats remain available in case of a booking failure. For brevity, the objects in Cabin/Layout and Cabin/Row have been removed from this example.

Show Example seat map response for booking with existing seat assignments

The current seat assignments are returned in HeldAncillary starting on line 328.
