Air Sessions

Travelport Universal API offers an array of session abilities for air booking. The session workflow is intended to be granular or incremental, allowing the user to validate or branch based on success or failure. Using this workflow, you can add air segments within a session, so that the consuming application can more easily process warnings and errors, and you can coordinate the workflow in a succinct fashion.

The table below offers an example workflow, following a sessionless shop and price.
