I don't think ITN shows any FF award seats; they show revenue seats only. Someone correct me if I'm wrong.

F7 Y7 B7 H7 Q7 W7 G7 V7 N7 K7 Z7 M7 shows how many seats are available at particular fare code, i.e. 7 K class tickets.

F - First class
Y - full coach
B - full (discount) coach
H,Q,W,G,V,N,K,M,Z - discount coach

There were postings regarding fare code a while ago.
