>>1086756Well, this figure is only the range of those planes at their given payload, and is not the whole story.
As I said, 77L and 359ULR can make it from Asia to South America, but the amount of passenger those plane can carry for the trip would be limited.
With 77X, it have more nominal range, but at the same time it also mean that for a certain stage length it would be able to carry more passengers on the plane to reach destination. That and the new aircraft's improved economic could make it work.
And also, I forgot that Bogota and Caracas are actually part of South America. Their distance from Tokyo/Seoul/Beijing is actually less than DOH-AKL the current world longest 77L route, although the 77L being used to flown DOH-AKL only have ~260 seats either.
