Hi Ryan Chua ,
Thank you for your message.
The group fare can be combined with the half-fare reduction, so we recommend that you buy a group ticket.
Group tickets cannot be purchased on our application and in order to benefit from the preferential fare, a reservation is required.
For information, you can call our SBB Contact Center on 0848 44 66 88 (CHF 0.08/min).
Have a nice evening,
LoredanaD
