I am going inter-railing with my son this summer; my friend is also going inter-railing with her 2 children at the same time. We have decided to do the “first leg” together. I am trying to book Eurostar tickets, from London to Paris, for all 5 of us to ensure we have seats together. However, I seem to need to add my friends pass number and her children’s pass numbers to my trip on my mobile app in order to book seats for them. I’m aware that each pass is only allowed to be on one device, does anyone know if I add my friends pass number to ‘my trip' in order to reserve the seats does that then mean their passes are on my device? We are not travelling beyond Paris together so I don’t want to end up with them not being able to travel without my phone!
