Yes, this is possible provided
- it is not the 4-days promotion pass which has been on offer in fall 2022
- it was bought with SBB and not with an agency or third-party supplier
- and, for the e-ticket version, the first day of validity is still in the future
If all conditions are met, please seek assistance with any SBB ticket desk.
