Hi. I am planning to travel from Zermatt to Milano Centrale. However when i attempt to buy the ticket on SBB mobile app it shows that the message "Ticket purchase not possible".
1, Should i be buying a ticket from Zermatt to Visp using the SBB app and Visp to Milan using the Trenitalia separately?
2. Am i right to say that the half fare travel card will only be applicable from Zermatt to Visp?
3. Do i need to make seat reservations, if so can i do on the app or in person at the train station?
4. What is difference between supersaver ticket($9.40) and supersaver class upgrade ($7.20) with half-fare card? Why would a class upgrade be cheaper?
5. Is it true that tickets are no longer required to be validated before travel? Does that apply to tickets bought on the SBB app?
Thank you very much
