Hello, I had a discover EU ticket last year, but this year I have an interrail ticket. When I want to make seat reservations, I have to select a journey, but the only journeys that are shown to me, are the ones that are on my discover eu app. But the journey that is connected to my valid interrail pass is not shown, so when I make a reservation, how do I know if it is connected to my pass, if the journey is not connected to it?
Plus, my girlfriend has a discover EU ticket. Can we book seats that are next to each other because she can‘t add my pass to her reservation and it says we have different pass conditions, but I could connect her pass to my reserstion. Maybe this is because when I want to connect, it does not connect to my interrail pass but my discover EU pass from last year that is invalid.
Does anyone have an idea on what to do?
Or is there another option to book seats in france, like on the sncf-website?
I hope someone can understand my problem.
Thank you!
