Airlines are well known for making a living out of price discrimination. As the Ryanair boss put it once, there will always be some who want the whole service and pay for the business class. (Did Ryanair actually start to offer transatlantic flights now?)
Anyways, I received recently one of these email commercials from KLM letting me know that they have great offers from Germany to Mexico City. I receive these offers because 10 years ago (when still having my main residency in Germany) I thought that I will be flying a lot in the future. So I subscribed to their Miles and More program: I never made it to get even a single flight for free. Clearly, I blame this on the fact that I always got better tariffs with the cheap airlines.
Anyways, so I followed the link and indeed for roughly 500 Euros they would bring me in March to Mexico City so I can have some cold tequilas....Since, I always thought about going and visit a friend there, the commercial actually caught me. So, I got somewhat more serious about this and checked what a flight from Switzerland (same airline and distance, via Amsterdam) would cost. The answer was shocking: The identical flight cost me roughly the double 1500 SFR and both are the "best price offers"!
Now, I knew for a while that it nearly always pays to travel to Germany (by train or low cost carrier) and then fly form there to your vacation destination. But 500 Euros difference is enormous for potentially 2 hours difference in a anyways long traveling time of close to 20 hours (i.e. you could just take an Easy Jet plane to Amsterdam and fly directly from there spending some more time due to a worse connection).
I believe that the reason why it pays still to price discriminate so much is that people are too lazy and in particular the Germans are known by "Geiz ist geil" while the Swiss are rather known for quality and high standards potentially looking less towards the price. Or in plain economics: Compared to Germans, Swiss put on average a higher value on time.
The question remains whether this is a cultural thing or (what my guess would be) a matter of who actually takes these flights, i.e. the share of business motivated travels to vacation travels are lower when traveling from Zürich or Geneva to Mexico City than from Stuttgart or Frankfurt to Mexico. Clearly a UN dummy might also do a good job ....
