Me and three friends have activated 2nd class Interrail passes and booked almost all our trains and seats. We are trying to book the Eurostar through the weblink https://www.b-europe.com/EN this website provides. As we reach the end it asks for all our names and “Pass Cover number.” No matter how many times we put in our Pass numbers given to us they say it is wrong and we can’t pay for the seats without it. It says try on the paper pass but we have mobile.
Has anyone else had this issue or a way around it to book the Eurostar? I have tried the Eurostar website too but can’t find a way to put our interrail passes in for discount?
Thanks in advance.
