I am new to Fare Information . I was searching for AMS-NYC on a direct KL flight. According to the Fare Information the cheapest way is V class which is a round-trip for 299,- euro's. Than, when I take a look at Flight Information all KL flights during the season will never give me a V class. They all look like this:
J9 C9 S9 B9 M9 K9 H9 L9 Q9 T9

Why does V class never show up? I don't understand as Q class is the second cheapest which costs 427,- euro's instead of 299,- euro's.

Also, the K, L and T class don't show up on the Fare Information but are available in Flight Information shown above.

Could someone could explain that to me?
