2 adults, 2 teens under 16.
Per recommendations here we have purchased the 1/2 fare card plus family pass.
Practically speaking my understanding is we use the 1/2 fare option when purchasing the tickets on the SBB app.
We need to have a pdf of the 1/2 fare pass available if requested.
The purchased tickets will be on the app but our passes will not be.
As for the teens, do I need to get them tickets and if so how? There is no option shown for family pass on the SBB app.
Thanks, this is our first trip to Switzerland and trying to learn BEFORE we arrive.
