Guangzhou Baiyun International Airport is the main airport of Guangzhou, the capital of the province of Guangdong, People's Republic of China. Both airport codes were inherited from the previous Guangzhou airport, and the IATA code reflects Guangzhou's former romanization Canton. The airport is the main hub of China Southern Airlines and a focus city for Shenzhen Airlines.
In 2010, Guangzhou Baiyun International Airport was China's 2nd busiest and World's 19th busiest airport in terms of passenger traffic, with 40,975,673 people handled. As for cargo traffic, the airport was the 3rd busiest in China and the 21st busiest worldwide. Guangzhou airport is also the 3rd busiest airport in terms of traffic movements in China.
The opening of the New Guangzhou Baiyun International Airport had relieved most of the controversies of the older and deteriorated airport because of the limited space, overcrowding and lack of expansions. Its opening allowed it to overcome curfews and restrictions and begin a 24 hour operation. This meant that China Southern Airlines could highly utilize their intercontinental routes by flying overnight. Other airlines have this benefit too.
