My husband and I will be in Switzerland in mid September. We already have our seat reservations on the Bernina Express. We have Swiss travel passes so are we good to go or do we still need to buy tickets? When we went online to get tickets it kept taking us to seat reservations that we already have so I’m hoping that means we just show up with our travel passes and are ready to go.
If you have booked 2nd class seats, you're good to go.
If you have booked 1st class seats but only have a 2nd class pass, you need to purchase an upgrade. If you cannot figure out how to do it online, you can do it at a station once in Switzerland: upgrades do not sell out.
If you have booked 1st class seats and have a 1st class pass, you're good to go as well.
