I am trying to book train seats from Strasbourg to Champagne-Ardenne. On the Interrail website, it wants to charge me 44 Euro (2 passengers). On the travel.b-europe website it wants 24 Euro. Excellent. Unfortunately, travel.b-europe won’t let me proceed unless I enter our Interrail pass numbers and it will only accept paper passes whereas ours are digital, so it tells me the pass numbers are invalid.
I also tried booking on the SNCF website but there seems to be no option to only book seat reservations.
Any ideas? Thanks.
