to handle a maximum of 620,000 flights per year (102 per hour, or about one flight every 36 seconds). There are 49 frontal stands at the main passenger concourse, 28 remote stands and 25 cargo stands. There are also five parking bays at the Northwest Concourse. A satellite concourse with 10 frontal stands for narrow body aircraft has been commissioned to the north of the main concourse at the end of 2009, bringing the total number of frontal stands at the airport to 59. The airport was the busiest for passenger traffic in Asia in 2010, and the world's busiest airport for cargo traffic in 2010. In terms of international traffic, the airport is the third busiest for passenger traffic and the busiest for cargo since its operation in 1998. There are over 95 international airlines providing about 900 scheduled passenger and all-cargo flights each day between Hong Kong and some 160 destinations worldwide. About 76 percent of these flights are operated with wide-body jets. There is also an average of approximately 31 non-scheduled passenger and cargo flights each week. The operation of scheduled air services to and from Hong Kong is facilitated by air services agreements between Hong Kong and other countries. Since the opening of HKIA, the Government of the Hong Kong Special Administrative Region has implemented a policy of progressive liberalisation of air services. Many low-cost airlines have started various regional routes to compete head-on with full-service carriers on trunk routes. The airport's long term expansion opportunities are subject to variables. The airport opened its third runway in July 2022 as part of a HK$141.5 billion expansion project that would increase its land footprint by 50%. On the other hand, there exists only one airway between Hong Kong and mainland China, and this single route is often and easily backed up causing delays on both sides. In addition, China requires that aircraft flying the single air route between Hong Kong and the mainland must be at an altitude of at least 15,000 feet. Talks are underway to persuade the Chinese military to relax its airspace restriction in view of worsening air traffic congestion at the airport. Other than that, Hong Kong Airport Authority is co-operating with other airports in the area to relieve air traffic and in the future, Shenzhen may act as a regional airport while Hong Kong receives all the international flights.
