In the event that i purchase supersaver half fare tickets, but did not purchase the swiss half fare card, could i pay the difference to the conductor on board the train? ( eg. saver ticket is 40CHF, top up additional 40CHF with the conductor?)
Reason being is that i have only 4 train rides scheduled and if i were to purchase the swiss half fare card at 120CHF, it would cost more than if i had paid full fare for these 4 train tickets. So is there an option for me to convert them to full fare tickets with the conductor? Thank you for reading and assistance rendered.
