Production https://api.travelport.net/11/air/

Travelport has updated all JSON API authentication and authorization endpoints. Previous pre-production endpoints were deprecated 5 Dec 2025. Previous production endpoints are scheduled for deprecation 30 Jan 2026. API transactions using these endpoints after these dates in those environments will fail. See Endpoint Migration for details.

The Ancillary Price request confirms pricing for a selected ancillary. It can be sent either as part of the initial booking workflow, or for an existing reservation. The request uses the same endpoint and payload in each flow. See the Ancillary and EMD Guide for currently supported ancillaries in each flow.

You must first create a new or post-commit workbench and send an Ancillary Shop request. After pricing, add the selected ancillary to the workbench.

Ancillary pricing is a required step for NDC ancillaries. Not supported for GDS.
