A first timer here on using Interrail passes. I will be using a first class pass. I am going to travel from Hamburg to Venice with my family and we will use the Brenner route, traveling from Munich. I read that there was a supplement fee that you had to pay if you entered Italy from Austria. I bought my tickets through the ÖBB website, but I mistakenly booked them using the “Seat reservation only” option. I can’t get my tickets refunded, and I am worried that the ticket could be refused.
I was wondering if it was possible to pay the supplement fee by local means instead. Can you speak to a staff member in Munich or on the train if you want to pay it there? If so how do we do this?
