I made a seatreservation from Basel to Chiasso. This train, the EC151, goes to Milan. That's the city where We have to go. But a reservation from Chiasso to Milan is impossible when ik look at the trainorganisations ÖBB, DB and NS international. How do I solve this problem? It's the same train so We can stay in the train. Or what can We do?
The day of travelling is 27th of July.
