Is there any predictability as to when open seats are moved to NF status? Looking at a flight less than 16 hours away. It's F6, A6, NF0 (as shown in expert mode through .bomb. Looking at other flights to the same destination on the same day, many of the open first class seats already show as NF. The flight is SFO-OGG. The other flights to which seats have moved to NF are another SFO-OGG flight and LAX-OGG flights. At least it's cool to be looking at the upgrade list on the mobile app.
