The Swiss Transfer Ticket is valid for a maximum duration of one month after the first date of travel. If you purchase the online ticket you must decide the days of travel whilst purchasing.
You must travel on the most direct route to and from your destination. You can break your journey on route but you must complete each journey within one day.
The ticket can be used to travel from an airport or border point to your destination and back. Bern, Geneva, Lausanne, Lugano and Zurich Main Station are all border points.
The Swiss Transfer Ticket is only valid with your Identity Card or Passport, which must be shown with the ticket if you are subject to an inspection.
Your age is determined on the first date of travel, regardless if you have a birthday during your trip (eg if you are aged 15 at time of departure, you can have a child’s ticket, even if you turn 16 before your return).
