Hi
I had purchased my 2nd class Swiss travel pass ticket. However, ticket purchased unable to link to the SBB apps becox It was purchased via kkday. However, I would like to upgrade certain route to 1st class
Can I just go to SBB apps to upgrade? Since I already know time and date to travel, can I just go to *Supersaver Class Upgrade and purchase the upgrade to 1st class..?
When ticket check⦠Do I need to show both.. 2nd class pass and also the purchase of class upgrade..?
