I have a 2nd class Swiss Pass Ticket and I have made Reservation for a Class 1 ticket for the Glacier Express travelling from Zermatt to St Moritz on 19 Oct 2016. It seems like the 2nd Class tickets have been fully reserved. Where can I buy the upgrade tickets to upgrade my Class 2 Swiss Pass to Class 1 for this single journey and how much is the cost?
Can I buy the upgrade tickets in advance?
