Getting cheaper Bahn fares via external services

Imagine you want to go from some random place in Germany to the capital. Maybe because it is LinuxTag. We learned that you can try to apply international fares. In the case of Berlin, the Netzplan for Berlin indicates that several candidate train stations exist: Rzepin, Kostrzyn, or Szczecin. However, we’re not going to explore that now.

Instead, we have a look at other (third party) offers. Firstly, you can always get a Veranstaltungsticket. It’s a ticket rated at 99 EUR for a return trip. The flexible ticket costs 139 EUR and allows you to take any train, instead of fixed ones. Is that a good price? Let’s check the regular price for the route Karlsruhe ←→ Berlin.

The regular price is 142 EUR. Per leg. So the return trip would cost a whopping 284 EUR. Let’s assume you have a BahnCard 50. It costs 255 EUR and before you get it, you better do the math whether it’s worth it. Anyway, if you have that card, the price halves and we have to pay 71 EUR for a leg or 142 for the return trip. That ticket is fully flexible, so any train can be taken. The equivalent Veranstaltungsticket costs 139, so a saving of 3 EUR, or 2%.

Where to get that Veranstaltungsticket you ask? Well, turns out, LinuxTag offered it, itself. You call the phone number of the Bahn and state your “code”. In the LinuxTag case it was “STATION Berlin”. It probably restricts your destination options to Berlin. More general codes are easily found on the Web. Try “Finanz Informatik”,
“TMF”, or “DOAG”.

I don’t expect you to be impressed by saving 2%. Another option is to use bus search engines, such as,, or You need to be a bit lucky though as only a few of those tickets are available. However, it’s worth a shot as they cost 29 EUR only.

That saves you 80% compared to the original 142 EUR, or 60% compared to the 71 EUR with the BC 50. That’s quite nice, already. But we can do better. There is the “Fernweh-Ticket” which is only available from LTUR. It costs 26 EUR and you need to poll their Web Interface every so often to get a chance to find a ticket. I intended to write a crawler, but I have not gotten around to do it yet…

With such a ticket you save almost 82% or 63% compared to the regular price. Sweet! Have I missed any offer that worth mentioning?

Finding (more) cheap flights with Kayak

People knowing me know about my weakness when it comes to travel itineraries. I spend hours and hours, sometimes days or even weeks with finding the optimal itinerary. As such, when I was looking for flights to GNOME.Asia Summit, I had an argument over the cheapest and most comfortable flight. When I was told that a cheaper and better flight existed that I didn’t find, I refused to accept it as I saw my pride endangered. As it turned out, there were more flights than I knew of.

Kayak seems to give you different results depending on what site you actually open. I was surprised to learn that.

Here is the evidence: (you probably have to open that with a wide monitor or scroll within the image)
Kayak per country

In the screenshot, you can see that on the left hand side found 1085 flights. It also found the cheapest one rated at 614 EUR. That flight, marked with the purple “1”, was also found by and at different, albeit similar prices. In any case, that flight has a very long layover. The next best flight returned was rated at 687 EUR. The other two Kayaks have that flight, marked with the green “3”, at around 730 EUR, almost 7% more than on the German site. The German Kayak does not have the Ethiad flight, marked with the blueish “2”, at 629 as the Irish one does! The American Kayak has that flight at 731 EUR, which is a whopping 17% of a difference. I actually haven’t checked whether the price difference persists when actually booking the flights. However, I couldn’t even have booked the Ethiad flight if I didn’t check other Kayak versions.

Lessons learnt: Checking one Kayak is not enough to find all good flights.

In addition to Kayak, I like to the the ITA Travel Matrix as it allows to greatly customise the queries. It also has a much more sane interface than Kayak. The prices are not very accurate though, as far as I could tell from my experiments. It can give you an idea of what connections are cheap, so you can use that information for, e.g. Kayak. Or, for that other Web site that I use: Skyscanner. It allows to list flights for a whole months or for a whole country instead of a specific airport.

What tools do you use to check for flights?
