About the Swiss Transfer Ticket
As of 2019, the Swiss Transfer Ticket is no longer available. The product offered a journey by public transport, from the Swiss border or a Swiss airport to any town in Switzerland, and back. It was used by people who did not travel much once they reached their destination (e.g. for a ski holiday).
Swiss Transfer Ticket alternatives
If you need more than two trips, other rail passes might be an even better alternative.
