Re: How is the Boeing 747-8 a good freighter but a bad passenger craft?

Belugas and dreamlifters are too specialized to be practical for any cargo airline to run. And if you really need it, it'd be cheaper to approach Airbus and Boeing (though I'm almost certain the dreamlifters are actually contracted) to do a short lease. Same goes for nose-loaded cargo. It's better ...

Re: How is the Boeing 747-8 a good freighter but a bad passenger craft?

This is exactly what I thought as well. The 747 is the only widely-used freighter with the ability to load oversized freight through the nose. The other possibility I can think of, is like you said, the 747-8i was not as successful as the 747-8F. I imagine some good discounts are being given to cus...

Re: Rumor: Airbus to launch A350-1000ULR

Your estimates for the A35K payload over 7600nm seem on the low end. The 316t A35K can haul 35t over 8400nm. Limiting the range to 7600nm allows to trade at least 9t of fuel for payload. The design range was increased yet again from 8400 nm to 8700 nm. https://www.airbus.com/aircraft/passenger-airc...
