Looking at buying an interrail pass for a long journey. The eurostar 1st class is all sold out and the rest of the journey will be sleeper, so there’s only part of the journey (Zurich to Wörgl) that I would to take business class.
Can I purchase 2nd clas reservations and then buy an upgrade? From 2nd to 1st, then pay the 15 euro supplement for business.
The difference in interrail pass classes (£180) is cheaper than buying this ticket separately (£310) so cheaper for me to get the 1st class pass than buying it separately, but if I could have 2nd class and an upgrade, that would be better.
