Hello runo1428
Without a Swiss Half Fare Card, you are not entitled to purchase tickets that read ‘Half Fare Travel Card (½)’. You have to choose the same ticket yet full fare (1/1).
If you tell us the route you would like to take, we can come up with a real example.
Keep in mind, if you miss the train for which you purchased a Supersaver ticket, and it is your fault that you missed your train (or because the flight was late), the Supersaver ticket is no longer valid, and you must repurchase a new full fare ticket at regular cost.
Kind regards,
Roland
