I just TTU'ed about NW808 aboard N809NW on the 2nd. AVOD and the seats themselves all worked fine, but plugging anything into 6C/6E made the green light go off immediately, and no power was available. Even just the transformer to charge a mobile phone, without the phone connected. And there were only 1-2 laptops being used on the whole plane.

(Followup: 10K + thanks for being specific about exactly which seats on which aircraft, and they'll forward that to the maintenance folks. If 10K seems low, remember that this was technically a domestic F flight that just happened to be in a WBC seat.)
