the US majors have decided to move in another direction (lean on the FAA until ETOPS 330 is granted) which is their choice.
The US majors are not the world airline industry (any more) so 380 sales will probably go where they are going now - airlines in Asia where they can pile high and sell cheap. SAA is by their own admission another possibility but that airline is showing ever more signs of political sabotage so doubtful an order will ever come.
The question is: if you believe the 380 is a lemon because all the airlines want is a 773ER/LR then 747 Advanced is an equally stupid idea - right?
