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.
These planes are becoming the most popular to cut costs of the airlines. The most common narrow bodies are the 737, A319, and A320 which average 150 to 200 seats. The most common Wide Bodies are the 747, 767, 777 and A340 which average 250 to 500 seats. The A380 will have the capacity to hold about 800, but the airlines are configuring them to hold about 550.
