Hello Yuembiebos42
Are you going to France? Or why will you change trains at Geneva?
A point-to-point ticket is valid for any connection, so it does not matter which train you are going to take. Our trains are free-seating, no seat reservations are required.
If you travel on a Supersaver ticket, it is valid for the connection that you have chosen during ticket purchase. If the train is late, you can take the next train. If you are late and miss the train, you have to purchase a new ticket.
In case you will travel with children, and this will be the only journey you will do in Switzerland, you can purchase the Day Pass Children for them.

For a better advice on the tickets, you would have to tell us who is part of your family (age of the family members) and why there is a train change at Geneva needed.
Kind regards,
Roland
