Hello
I'm a tourist and I have bought a swiss half fare travel card @120CHF valid for 1 month.
While checking out, i saw under Reduction field , a drop down bar with one of the options as Half fare - travel card 1/2/3 years, but the card i hold is only 1 month?
Is this the right selection to enjoy 50% off this journey?
Do I need a separate ticket from Domodossola?
Do i buy this additional ticket either from SBB or trenitalia ?
