*The 748 can fly about 30t more the same range as a full 77F can, 103t/4000nm vs 134t 4000nm?* |

Actually max. payload on the 777F is closer to 107t, but this discussion is not about how far the aircraft can carry their max. payload, but whether it's economical to perform ULH flights on freighters. I still don't know how the 748F compares to the 777F on sectors of 6000+

NM, but know for a fact a 777F will outperform a 744F, even an

ERF, quite considerably. To the tune of being able to carry nearly double the payload on a 14+ hour sector.

The 777F can carry its max. payload out to around 10.5 hours, which is roughly 4500NM. With 125 tons of fuel, enough for around 17 hours of flying, the 777F can still carry 70 tons. We crushed numbers of a proposed

IST-

SYD charter, and the 777F could carry around 60 tons. On the way back, direct to

LEJ, the sector would be around 21 hours, and yet the bird could still carry 25 tons of payload. You will not see those kind of numbers on a 744ERF, and I doubt the 748F can play along either.
