Asia Pacific airports move up the ranks in 2011, with Beijing this year to overtake Atlanta

The rankings of the world's busiest airports for 2011 show key developments and lasting changes in global aviation, although the world's busiest airport by total passenger movements, Atlanta Hartsfield-Jackson International Airport, continued to hold off Beijing, the world's second busiest airport, in 2011, according to Airports Council International (ACI). It is, however, expected that Beijing, driven by exponential GDP growth, will overtake Atlanta in 2012, ending the airport's 14-year reign in the top spot.

While Beijing Capital is the dominant airport in China, it is on track to become be the world's busiest hub by the end of this decade, leaving London and even ambitious Dubai in its wake. And new developments will ensure the city of Beijing has an airport in the top spot: its new airport at Daxing, south of Beijing, could have up to nine runways and ultimate capacity to handle around 370,000 passengers per day, or a staggering 135 million passengers p/a. This would increase capacity at Beijing area airports to around 220 million p/a - almost a quarter of a billion passengers.
