Scientific Explanation

The ranking of airports by size involves both physical area and operational capacity. Larger airports require more land to accommodate multiple runways, terminals, cargo facilities, and ground transportation infrastructure. The geographic location also plays a role—airports in sprawling Western states often have more available land than those in the densely populated Northeast. Operational metrics such as passenger volume, flight frequency, and connectivity further influence an airport's status as a "major" facility.
