NR wants the 777Fs, but I am not sure how much what he wants factors into a major aircraft purchase like this.
The freighter fleet will be getting pretty lean once 9 BCFs leave for ACC and AHK. Those departures essentially turn the 10 -8s into a capacity increase only, not fleet growth. Funny, that's exactly what the ERFs were - a one to one replacement for the classics.
Wonder where they would fly 777Fs? ULH to NAM if they follow the passenger model, but I think they would probably just put the right-size freighter on the demand for the day. Can you say Roster Disruption? 16.3?
