1st Class Upgrade Questions

[BUYEOL]

I've already bought a second-class Swiss pass.
I'd like to know how to buy a first class upgrade ticket for 1 day.
. Can I get a discount if I make a purchase after 9 a.m.? (If yes, how much is it?)
. Can I buy it only at the station?
. Can I buy it from a clerk on the train?

Thank you.

Hello @BUYEOL

With the Swiss Travel Pass and Swiss Travel Pass Flex, you have the option of a half price class upgrade for a specific route or a daily class upgrade.

More information about the upgrades you will find here: https://www.sbb.ch/en/travelcards-and-tickets/tickets-for-switzerland/class-upgrade.html
