Dear Sir or Madam
Hello,
I am planning to visit Switzerland for my honeymoon from October 8 to October 14, and I have already purchased train tickets in advance.
However, I mistakenly selected the “Half Fare Card” option when booking. I would like to change the tickets to the “No travelcard” option and pay the full fare instead.
Could you please advise if it is possible to modify my existing tickets, or guide me on how to proceed with this change?
Thank you very much for your assistance.
