anything to disparage the 380
I think you misread the reaction of Boeing people to the A380 faithful. It's not disparagement, it's mild amusement tinged with pity for anyone who could be so self-deluded. Sort of like meeting a modern-day Communist.
Why not dredge out a flight plan for NYC for both types? Brace yourself for a small shock. The 380 carries an extra ten tons on that trip for which it squanders an extra 60 tons of fuel. So six tons of fuel wasted for every ton in which it outdoes the 777.
That's not just bad business and a noxiously inefficient airframe, it is a crime against common sense and the environment.
Emirates has 380s because they were essentially free and they make nice mobile billboards. As it becomes more and more important to actually operate efficient and well-designed airplanes they will gradually disappear. I am looking forward to the spin which explains that move as the existence of the bloated blighted device on our flight line is a tragedy which cries out for a little humour.
