I have a global mobile pass and I have booked the first train from Utrecht (Netherlands) to Milan in the Rail Planner app. Do I make a seat reservation on the ÖBB website/app? And I'm travelling together with someone else. Can I book the seat reservation for them too? Do I just fill in our names, buy the reservation and show it together with our Interrail Ticket of do I need to link them somehow?
I hope someone knows the answer :) Thankyou!
