On 1 August 2022, Deutsche Bahn (DB) will become the first intermodal partner of the Star Alliance, the world’s largest global airline alliance. The collaboration will allow DB and Star Alliance passengers to book integrated international plane and train journeys through one platform. Customers will then receive a combined ticket for flights and train journeys, including a seat reservation.
At Frankfurt Airport, passengers will also benefit from accelerated baggage handling and other services in the AiRail check-in area. In addition, business and first class customers of Star Alliance member airlines will have access to the DB lounges.
Is this really new and unique? I’m fairly sure that certain BR stations have appeared in airline GDS systems in the past with airport codes (beginning Q I think) and you could book through tickets in the same way you could book any airline multi leg journey.
