How do I get the cheapest tariffs?
Seats on board of our aircraft are, depending on the flight, separated into different tariff classes.
The first tickets for a specific flight are sold in the lowest tariff class. As soon as this class is sold out the next class then opens. Prices increase gradually.
Generally you can say:
The earlier you book, the cheaper the prices.
As soon as you find an interesting price you should book right away as this flight could get more expensive the next time you look. Very often it is also worth to compare prices with alternative flights some days earlier or later.
