Just checked NW17 (JFKNRT) and 27 (SFONRT). I think a business class award ticket is booked under D, right? (Sorry, if I'm mistaken.)

For NW 17, up to Nov. 30, there was at least a seat available and for NW 27, one at least available up to Nov. 20.

None for 1DEC, 2DEC, 5DEC, 10DEC, 17DEC for both routes.

They have not just released any seats in DEC?
