The 10 Busiest Airports in the United States. Hopper has compiled a list of the United States' 10 busiest airports based on passenger traffic.
Fly from Sydney to Hong Kong on a Qantas Airbus A380 and you'll find the 180-degree fully flat beds, but a Qantas Boeing 747 on the same route has angled lie-flat beds. To make things worse, both Qantas products are called Skybeds â- but only the A380's second-generation Skybed is a fully-flat seat.
The website said the seat pitch (the space between the back of one seat and the back of the seat behind it) will remain 32-34in and the width will be slightly smaller at 17.5in â half an inch less than Emirates' three-class A380s, which have fewer economy seats.
