Developer Advisories for Upcoming Features

Travelport has released developer advisories (DAs) for the following upcoming features. DAs are issued for changes that may significantly change code and/or functionality in the JSON APIs. You must sign into My Travelport to see the full DA. Contact your Travelport representative if you have questions about how an upcoming release may affect you. After a feature has been deployed, it moves into the release notes area of this page and is no longer listed in this section.

General Functionality

Most deployments for both GDS and NDC content are included in an API-specific releases. Cross-API and more general updates are listed in this section.

NDC Bundled Offers

In the Search request, adds the custom modifier includeBundledAncillariesInd to request NDC offers that include an ancillary service bundled with the cost of the air fare. This could be a discounted paid seat, or any other ancillary service offered by the carrier. In the Search and AirPrice reference payload responses, for bundled offers, PriceBreakdown returns an instance with the new @type PriceBreakdownAncillaryAir to define the included ancillary and pricing.

NDC bundled offers are supported in the Ancillary Shop and Price requests as for any other offer. In the Ancillary Shop and Ancillary Price responses, the indicator bundledInd=true is returned in only the first instance of ProductAncillary for any NDC bundled offer.

Bundled offers can be booked with the Add Offer reference payload request as for any other offer.

NDC only, not supported for GDS.

Credential Access Manager

Travelport has launched a credential access manager to support creating and managing your JSON API credentials:

• Primary Identities (previously Primary Runtime Users) allows you to create a primary identity to connect with the JSON APIs, rotate primary identities, disable suspected compromised primary identities, and view all PCC Pseudo city code. A travel provider's identification code for the APIs, provisioned from Travelport. Used to determine access and other settings in the APIs for your company./access group content.

• Managed Identities (previously Managed Runtime Users) allows you to create credentials for integration with third-party applications developed using the JSON APIs, share access to the JSON APIs with your own collaborators and development teams, and access client credentials (client_id and client_secret headers) to allow applications to authenticate and connect with the APIs.

See the Knowledge Base article Credential Access Manager in MyTravelport for full details. See Knowledge Base Resources if you need login assistance.

NDC Disruption Handling

Introduces standard flows for handling NDC flight disruptions. In the Reservation Retrieve response, adds the Offer @type OfferModify with scheduleChangeInd set to true, and an additional instance of Product @type ProductAir to support returning both the disrupted and new flight segment details for each journey or leg. Customers can then choose to either accept the change, rebook the itinerary, or cancel for a refund per the carrier rules for the disruption. See NDC Flight Disruption Handling in the Booking Guide for details.

Air Offer

Air Offer 26.11.17W: Unique identifier for split ticketing in AirPrice response | 22 Apr 2026

Adds the following new functionality and objects:

• Premium Flex Search point of sale (POS): In the Search request, send PricingModifiersAir/MultiPricingAgency with up to three PCCs to search in addition to the provisioned PCC. PCCs must be a branch agency provisioned with access for the requested PCC.

• Premium Flex Search dates: In the Search request, send SearchCriteriaFlight/daysBeforeDeparture and/or /daysAfterDeparture with the value/s 1, 2, or 3 to search up to that number of days before and/or after the departure date.

The Accept header setting controls whether the response is aggregated (all offers are combined into a single CatalogProductOfferingsResponse objects) or streamed (multiple CatalogProductOfferingsResponse objects are returned consecutively).

When sending flex search requests, append /premiumflex to the existing endpoint for all APIs in the search flow: Search, Next Leg Search, and/or Flight Specific Search reference payload.
