Do you know of a site where we can check availability in the W and D booking classes?
</font>
The only way I know is : log in as BW or SW at the FD section of the KL website and check availability of a specific flight. The system will look for class W (economy) or D (business). Should you log in as RW member at the FD, the system will look
also for class B & M (economy) or C (business).

Are you sure S class is Business?</font>
Booking class S is full fare economy, a crazy expensive amount for a seat in coach. It can be combined with segments in C and goes first in operational upgrades to business in case of an overbooked flight. I presume by KL it is often treated as C.
