GDS Exchanges

Exchange Eligibility

The Eligibility API is the first step in the GDS exchange workflow. It is an optional step.
Eligibility returns information about whether a ticket may have value in an exchange or refund scenario, and the range of potential exchange and refund fees. This information relates only to fees and not any fare or tax difference for the itinerary.
Send either Ticket or Locator as a query parameter. Ticket returns eligibility details for only the one traveler on the ticket, while Locator returns details for all travelers on that reservation.
A request by reservation locator for a reservation that has multiple open tickets for one passenger will return eligibility information only for the last ticket listed in the reservation. In this scenario you should instead send the request by ticket number.
