We are happy to report that as of tomorrow morning, Eurostar passholder fares will be available in the All Aboard Dashboard and API.
This is a key milestone in our progress toward offering a wide set of seat reservations and passholder fares across Europe, with more operators to be supported in the coming weeks and months.
To book a passholder fare for Eurostar, sign in to the All Aboard Dashboard, and tick the "Passholder fares” check box in the regular ticket booking flow.
Seat reservations and passholder fares will be handled and defined much like regular tickets in the billing documents provided to you by us.
