# Seat Map The Seat Map request returns seat availability for both free and paid seats. It is a reference payload that sends identifiers from a previous transaction or a booking. You can send the Seat Map request at several places in the TripServices workflow - after searching, after pricing, during booking, and after booking. The Seat Map request uses the same endpoint but a different message payload depending on where in the workflow it is sent. See the supported workflow options in the [Seats Guide](https://developer.travelport.com/docs/flights/guides/seats-and-ancillaries/seats-guide). All Seat Map requests allow you to request seat maps for any of the following: All flights within an offer (all flights on the itinerary). All flights within a product (all flights on one leg of an itinerary). One or more individual flights. Standalone Seat Map sends flight criteria including a booking code to return a view-only seat map. Unlike the Seat Map request, Standalone Seat Map does not send any identifiers from a previously searched or priced flight. It is instead a full payload request and can be sent entirely on its own, either within or outside of a workbench session. Endpoint: POST /air/search/seat/catalogofferingsancillaries/seatavailabilities Version: 11.35.2 Security: bearerAuth ## Header parameters: - `TraceId` (string) Identifier used to correlate Air API invocations across a multi-call business flows. - `XAUTH_TRAVELPORT_ACCESSGROUP` (string) Identifies the Travelport access group with which the caller is associated - `travelportPlusSessionIdentifier` (string) travelportPlusSessionIdentifier used to maintain an established agency session - `TVP-PCC-Core` (string) Allows user to pass PCC instead of Access Group ID ## Request fields (application/json): - `@type` (string, required) Discriminator class CatalogOfferingsQuerySeatAvailability only Example: CatalogOfferingsQuerySeatAvailability - `SeatAvailabilityOfferings` (object, required) - `SeatAvailabilityOfferings.@type` (string, required) Discriminator classes SeatAvailabilityOfferingsBuildFromCatalogOfferings, SeatAvailabilityOfferingsBuildFromCatalogProductOfferings, SeatAvailabilityOfferingsBuildFromOffer, SeatAvailabilityOfferingsBuildFromOfferList, SeatAvailabilityOfferingsBuildFromProducts, and SeatAvailabilityOfferingsBuildFromReservationWorkbench Example: SeatAvailabilityOfferings - `SeatAvailabilityOfferings.CustomerLoyalty` (array) Including a loyalty number causes the seat map service to recalculate availability, pricing, and eligibility using the traveler’s elite tier and benefits. The returned seat map reflects what that specific customer can select, not just what exists on the aircraft. - `SeatAvailabilityOfferings.CustomerLoyalty.value` (string, required) Number on loyalty card. Example: 132456 - `SeatAvailabilityOfferings.CustomerLoyalty.id` (string) Optional Customer Loyalty Id. Not saved Example: Loyalty_1 - `SeatAvailabilityOfferings.CustomerLoyalty.priority` (integer) Optional Numeric Priority Code Example: 2 - `SeatAvailabilityOfferings.CustomerLoyalty.programId` (string) Specifies an identifier to indicate the company owner of the loyalty program. Typically two characters. For frequent guest number, the hotel supplier or brand code. For frequent flyer number, the air supplier code of the loyalty program. Example: HY - `SeatAvailabilityOfferings.CustomerLoyalty.programName` (string) Supplier's loyalty program name. Example: Frontier-EarlyReturns - `SeatAvailabilityOfferings.CustomerLoyalty.supplierType` (string) The type of supplier of a loyalty program. Uses 'hotel' for frequent guest number or 'air' for frequent flyer number. Example: Hotel - `SeatAvailabilityOfferings.CustomerLoyalty.supplier` (string) Supplier of a loyalty program (typically 2 characters representing the hotel, brand, or airline). Example: UA - `SeatAvailabilityOfferings.CustomerLoyalty.tier` (string) Customer Loyalty tier Example: Silver - `SeatAvailabilityOfferings.CustomerLoyalty.shareWithSupplier` (array) The list of suppliers that the CustomerLoyalty number is shared. Used for cross accrual programs. If valid carrier codes are not sent, the response returns the message NO CROSS ACCRUAL AGREEMENT EXISTS. - `SeatAvailabilityOfferings.CustomerLoyalty.cardHolderName` (string) Customer loyalty member name; up to 128 characters are supported. In Air Search, for discounted offers to be returned, the name must be sent as LAST FIRST; e.g., if SMITH is the last name and JORDAN the first name, send as SMITH JORDAN Example: John Smith - `SeatAvailabilityOfferings.CustomerLoyalty.validatedInd` (boolean) Customer loyalty number has been validated by the supplier Example: true - `SeatAvailabilityOfferings.CustomerLoyalty.prefix` (string) The cardholder name prefix title like Mr, Mrs, Dr Example: Dr - `SeatAvailabilityOfferings.CustomerLoyalty.given` (string) The First Name of the Cardholder Example: John - `SeatAvailabilityOfferings.CustomerLoyalty.middle` (string) Middle Name of the Cardholder Example: Wilkinson - `SeatAvailabilityOfferings.CustomerLoyalty.surname` (string) Last Name of the Cardholder Example: Smith ## Response 200 fields (application/json): - `CatalogOfferingsAncillaryListResponse` (object) The response of a Catalog Offerings Ancillary list endpoint request. For Seats, 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. 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. The Standalone Seat map response is the same as the reference payload seat map response, with the exception that a Result/Warning/Message is returned with the message 'The seatMap is view only'. - `CatalogOfferingsAncillaryListResponse.@type` (string) Example: response - `CatalogOfferingsAncillaryListResponse.transactionId` (string) A unique system-generated (128 bit GUID format) transaction/tracking id for a single request and response (i.e. for a single transaction) used for internal tracking and troubleshooting.

When used for reference flight calls, the CatalogProductOfferingsIdentifier will be the transaction identifier from the Search, Next Leg Search, or Flight Specific Search response in CatalogProductOfferings/Identifier/value. If you choose to pull the CatalogProductOfferingsIdentifier from the Price response instead (OfferListResponse/Identifier/value), either full or reference payload, please note for subsequent Add Offer requests you must remove the _PC appended to the end of the value in the AirPrice response (e.g., change value: '93d2091d-3d04-48ab-8091-6ae1525f02ea_PC' to value: '93d2091d-3d04-48ab-8091-6ae1525f02ea').

When returned from Air Exchange Eligibility, value is the ticket number sent with the eligibility request. When used specifically for form of payment, the value will begin with the characters 'FOP'. Similarly, the OfferIdentifier associated will begin with the character 'O'. For Hotel Create Reservation (Reference Payload), send the value from the Availability response in CatalogOffering/id or the value from SearchComplete returned in propertyItems/lowestPublicAvailableRate/rateKey/value. Results from Hotel Availability and Hotel SearchComplete are stored in the cache for 30 minutes. If the offers expire before booking, you must send a new request. Example: A0656EFF-FAF4-456F-B061-0161008D7C4E - `CatalogOfferingsAncillaryListResponse.Identifier.authority` (string) Name of the supplier system that created this identifier - the source of information.
