Good afternoon taselhoff
If you both travel around Switzerland for a day by train, tram, bus or ship, the travel companion ticket for CHF 38.00 is only valid for the accompanying person.
In this case you buy on best for you, because you have a half-fare card, a Super Saver Day-Pass and you buy the Companion ticket for your fiancee, since she doesn’t have any half-fare travel Card or a the General season Abonnement with us.
Fur any further information please visit this website here:

I wish you and your fiancee a wonderfull day trip around Switzerland. 🙂
Kind regards from Albania
