I bought a SAverDay 1st class ticket for use on Sept 15th, 2025. I will be traveling from Geneva to Grindelwald with two changes in Bern and Interlaken. I want to make a seat reservation but the tab to select that is not online nor is it on the app. When does SBB.ch make reservations possible?
the sub chat was no help - only said you can make a reservation up to one day in advance. For busy routes that is not helpful! thank you if you can answer this query.
