According to business consultants KPMG, the Beijing government is continuing its Hub-and-Spoke network, much like the United States model to move rapidly growing tonnes of cargo and passenger numbers. Between 2011 and 2015, 50 new airports will be opened, taking the total to 230, in line with the long-term goal set in 2008 of having 244 operational airports in 2020 and it is estimated that by 2030, another 5,000 aircraft will be needed to service demand. A central piece to the aviation development plan is a new Beijing Airport to accommodate the rapid growth in both domestic and international passengers.
