Hello Gononi87
Except if you have children under 16, all adult people will pay the same price.
You can search the timetable on sbb.ch, select a connection and you will see the prices. Usually the first prices displayed are Half Fare prices, but you are not entitled to buy half fare tickets without a Half Fare Card.
Supersaver Tickets: You can travel only with the selected trains, not refundable
Supersaver Tickets Flex: You can travel only with the selected trains, 75% refundable before departure
Saver Day Pass: Full flexibility, not refundable
Point-to-point Tickets: valid for one journey between the two stations with every train, refundable until the day before departure. Typically, it is not necessary to buy such tickets in advance, the price is always the same.
Kind regards
Danhiel
