Finding train ticket prices to compare Swiss passes

It is not you. There is a problem with the site right now.
But if you want a general idea until it resolves you can also search using https://www.raileurope.com
But I would not buy a ticket using raileurope as they markup the ticket up when you checkout

Well, if you know RailEurope marks up the ticket prices and you would not recommend buying from them...then why do you recommend someone to go there to make a price comparison?

Tim I see your point. Scrap that idea

You might try downloading the SBB app for your phone and see if the prices are on there.
In the meantime, it sounds like you are going to the Jungfrau area ("lifts and trains") and if so, you can look up those local prices here:

I'll also add that I think the regular price of a train from Geneva to Lauterbrunnen is around $90, and Zurich to Lauterbrunnen is around $80. Don't forget to also check out the Berner Oberland Pass if you are going to that area.

It is working now I can see the prices

thanks folks. Glad to know it wasn't my lack of tech skills. I will do my comparisons now.

Ok, I'm on the site looking at the pricing information, but I need further help. This is what it says: One Way
from Zurich airport to Lucerne Zurich Lucerne airport
Via Zürich HB - Ebikon
2nd class
1 × ordinary tickets, Half-Fare Card 125

Open tip

Valid: Thu, 30.08.2018

to Fri, 31.08.2018 05:00

From CHF 16.00
Why does it say: "1 x ordinary tickets, Half-Faire Card 125"? I did not enter a request for half fare. And what is an "ordinary ticket", if it has "Half-Fare Card" following and what does 125 stand for?

Also, I was wanting the fare from Zurich Airport to the city of Lucerne. Why does it say Zurich Lucerne Airport --->? Oh dear. It seems like it would have been Zurich Airport Lucerne.

There is no search option for from Zurich Airport;
You have to use Zürich Flughafen (which is in German for Zurich Airport) to Luzern
Searching 30 days in advance it will cost 15 CHF with a Half Fare Card 30 CHF without for non-stop.
I took that route my first trip to Switzerland 2 years ago and the price is the same except I was able to get Super Saver for 15CHF

The SBB site always defaults to list the price with the Half Fare Card. It is very common that people living there to have the Half Fare Card.

You can either select "no discount" for each ticket search, or double the "from" price. You can also see a number of price points already researched for you at https://www.ricksteves.com/travel-tips/transportation/trains/switzerland-rail-passes and on pages 129 and 404 of the current guidebook.

Zürich Flughafen to Luzern costs CHF 15.00, 2nd class with a Half Fare Card, or CHF 30.00 2nd class full fare.
These are fixed prices, for any train, any day. Swiss Railways, unlike other countries, doesn't have different prices for different trains. Are these the prices you were getting?

There are no stations on the Swiss rail network called "Zurich airport" or "Lucerne". If you enter these names on the SBB website, it will offer alternatives for each one, including Zürich Flughafen and Luzern. But you then have to select one of the alternatives;

Prices usually stay fixed for 2-3 years. They may go up this December when the timetables change, but if they do it will only be a few percent, and the passes will probably go up the same percentage.

Thank you again everyone, especially Chris, Laura and Jazz. I think I've got it figured. This forum is SO helpful!

We are leaving the end of September and will be in Switzerland the first week of October. I read some reviews and found
[1]: https://www.goeuro.com I was able to look at train schedules and prices and found trains much cheaper than the rail pass. A deciding factor was the question of either tight specific schedule or flexibility? We knew where we wanted to go and when, making the individual ticket option best for us. It was work figuring out the schedules, train stations and connections but I don't mind that type of thing.

We will be back mid October so I can tell you what problems we encountered and if we would use a pass next time. We will also be in Luxembourg, France, Austria and Czech Republic using trains.

I would put a question mark about using sites like GoEuro.
The definitive place to get fares and times is website of the company running the trains. In the case of Switzerland that is SBB (Swiss Federal Railways): https://www.sbb.ch/en

Any other website is a reseller, and resellers have a reputation of adding a markup to the prices and/or not listing or sellng tickets to all trains. Two I know are good ( https://www.trainline.eu/ and https://loco2.com/ ), but they only cover some countries and not Switzerland. Many others I know add surcharges, and I would avoid.
I have read no evidence for or against GoEuro, but I advise "caveat Emptor".
