Hello,
I am traveling from Milan to Lausanne in March. I will be using a Swiss Travel Pass Flex. I see in the timetable that there is an EC train from Milan to Lausanne, but it requires a reservation. I can't figure out how to make a reservation online. The SBB website does not give me the option for that trip. I am curious if this is because the trip crosses an international boundary. Please advise on how to make a reservation for the journey.
Thanks!
