We are working hard everyday to improve FAIRTIQ and to add new features. While FAIRTIQ has originally been thought to be an individual solution, we are aware of your need to be able to purchase several tickets with our system.
For now, it is therefore not possible to purchase several tickets on FAIRTIQ. We would like to offer this feature, it is however a big change in our app and our system that requires careful thinking and coding. We therefore cannot promise anything, nor give you a specific timeline.
Thanks for your understanding.
Note (for Switzerland): With the Junior Travelcard for CHF 30, children from the age of 6 up to their 16th birthday can travel for free on public transport for a whole year, accompanied by a parent with a valid ticket.
