I would like to buy a supersaver ticket and a saver day pass using the reduced fare ½. I noticed that for supersaver, I can add my children to the passenger list and select children co-travelcard under the discount and have a QR code of the ticket with CHF0.00 charge. However, for Saver Day Pass, if I add my children to the passenger list, I won’t be able to select children co-travelcard under the discount (in fact, only “No discount” can be selected). May I know if I need to buy a Saver Day Pass for my children, without any discount, in this case?
