ajamieson, I don`t understand your point....
As kurz pointed out in another topic, KLM award inventory for Royal Wing members comes out of the B and M inventory for Economy and out of the D and C inventory for Biz.
These classes are never sold out !!!
Especially not, if you book some weeks in advance.....
I check all these booking engines very frequently and I have never ever seen a KLM flight with only J and S inventory left ( their highest booking classes and only classes above the RW award classes.....)
So availability for Royal Wings is still great, despite some new members...
