The Airbus A380 dwarfs the planes at LAX; its double-decker design even makes the 747 look less jumbo. When Qantas’ flight from Melbourne and Sydney lands in L.A., special procedures are put into place and the airport grinds to a halt as roads and runways are closed so the huge aircraft can safely make its way to one of two gates that together cost $50 million to put in. Airport and Airbus officials disagree on whether larger delays will occur when more A380s are put into service.
