The BLS day ticket will no longer be available following the timetable change on 10 December 2017.
It will be sold for the last time on 7 December 2017 and the final date on which it is valid will be 9 December 2017. Instead, you can buy the new Saver Day Pass, which is valid for the whole of Switzerland. The earlier you book online, the lower the price. Early bookers holding a Half-Fare travelcard could therefore use the Saver Day Pass to travel second class on all lines within the GA area for only CHF 29.00.
