Hello, I am a student from Asia, and this summer I will be in Europe for the first time in my life.
I plan to go to Switzerland for a few days, and then take the ÖBB Nightjet (seats only) to Berlin. However, I've tried several times, and it says the seat cannot be booked (see attached pictures for reference).
What confuses me is that I chose to purchase the beta pass instead of the normal ones because it stated that no additional reservation fees are required. It also did not clearly mention any limitations with the pass. The train I want to reserve is about three weeks from now, but the system says the reservation must be made in paper form.
So, do I need to give up on the Nightjet and find another way to travel to Berlin?
