Release Notes

Travelport has updated all JSON API authentication and authorization endpoints. All previous endpoints have been deprecated as of 30 Jan 2026. See Endpoint Migration for details.

Below are release notes for major versions 25.11.x of the Travelport JSON Air APIs. Incremental minor version updates (25.11.x.y) are listed only when they include customer-facing changes. See Archived Release Notes for releases 25.11.x and earlier.

  • Version numbering uses this format:
  • {year of release}.{major model # of release}.{minor version of release}
  • For example, an API release numbered as 26.11.14 means it was released in 2026 on ODM model 11, and cumulatively across all releases on that model version is the 14th release on model 11.
