NOTES: 2010 data are through September. Data are for all scheduled and nonscheduled (chartered) service by large certificated U.S. air carriers at all domestic airports served within the 50 states, the District of Columbia, and other U.S. areas designated by the Federal Aviation Administration (FAA). Not all scheduled service is actually performed.
Since 2007 air traffic hubs are designated as geographical areas based on the percentage of total passengers enplaned in the area. Under this designation, a hub may have more than one airport in it. (This definition of hub should not be confused with the definition used by the airlines in describing their "hub-and-spoke" route structures). Individual communities fall into four hub classifications as determined by each communitys percentage of total enplaned revenue passengers in all services and all operations of U.S. certificated route carriers within the 50 states, the District of Columbia, and other U.S. areas. For 2004-2006, hub designation is based on passenger boardings at individual airports as designated by the FAA. Classifications are based on the percentage of total enplaned revenue passengers for each year according to the following: Large = 1 percent or more, Medium = 0.25 to 0.9999 percent, Small = 0.05 to 0.249 percent, Nonhub = less than 0.05.
