You should consider... Let's say only 6 seats are shown occupied on the seat map. Suppose 4 of these are for award travel. That might mean the entire inventory is gone.
For example, I took my family on a cruise in August. We had 4 F/C seats with mileage awards, and 2 F/C seats with upgraded awards. On the MD-80 we took nearly 1/2 of F/C!
