How to purchase Swiss Travel Pass discounted tickets online on in SBB app?

With the Swiss Travel Pass, use the GA Travel Card option, 1st or 2nd class, same as the type of STP you have.

GA stands for General Abonnement, which is what Swiss residents may have. The Swiss Travel Pass is only for visitors from outside of Switzerland, covers exactly the same travel benefits.

If you buy directly online from Jungfraujochbahn, they do have an option for the Swiss Travel Pass. Price is exactly the same for a return ticket, 95 CHF for the "Good Morning" Ticket with the Swiss Travel Pass or GA Travelcard. I believe it is good to return to Grindelwald as the prices are identical for travel from Wengen or Grindelwald.

Oh, got it, thank you, so I just check GA Travelcard in the SBB app. And someone checks the ticket, I present the Swiss Travel Pass to see why I've purchased the ticket with the correct price.

One more question if I may. Let's say I have a 2nd class Swiss Travel Pass and for only one particular journey I want to upgrade to first class? How can I achieve this?

You can buy a class upgrade for a route. It is one of the options that you will see when you start a ticket purchase in the app.

I believe you can do this with the app. The app has your 2nd class pass on it, so then you purchase a 1st class ticket, so you will be charged the price difference between a 1st and 2nd class ticket for your journey, or journey section.

Thank you so much!

You don’t actually purchase a first class ticket, just the upgrade.

Here are the steps:

For example Luzern to Interlaken Ost

1. Enter your departure and destination locations, choose day and time of your journey
2. On the bottom of the following screen you will see a red bar and "Tickets from CHF and an amount" Click on this
3. On the next screen you have choices for what kind of ticket you want to purchase. Scroll down to see "point-to-point class upgrade"
4. This is the ticket you will purchase

In my above example of Luzern to Interlaken Ost the cost is 12.00 CHF with a Half Fare Card.

Thank you very much for all the infos.

Regarding the Swiss Travel Pass discounted tickets online on in SBB app this is very useful with the GA Travelcard.

Online on official sites of forums you only find infos like "You can purchase the discounted tickets online or directly from the ticket counter. Please present your pass to make sure you’ll get the discount.", but nothing on how to “present” the pass when purchasing tickets online or in SBB app.
