Well, TC podcast on the ice system says that with the economics of the aircraft, he does not understand why other airlines don't have more A380s. My guess was 30 more, so 50 more surprised me. All I know is every time I do London, the plane is completely full, and we go 5x a day.
I don't know much about the 777x, but for deliveries over 3years after the A350, I would say our initial batch of the Bus is still coming. And it is still up on their "planning" map.
