The advantage of a B748F be to fly longer sectors with higher payloads and cut out the ANC tech stop/crew change requirement. I dont suppose anyone would fly around at absolute max payload (133,800kgs) as most cargo these days is volumetric.
How much extra "volume" does the B748F offer?
Re Your comments on "Classic" ACMI rates falling, why is this? If the cost of maintaining and crewing them (and insurance costs +++) - all components of ACMI which are increasing, why would rates be falling?
In terms of aircraft supply/availaiblity in the market surely market ACMI rates would be on the up.
