Recently Updated | World Top Airports | US Top Airports | UK Top Airports

According to the 2011-2015 National Plan of Integrated Airport Systems (NPIAS), there are over 19,700 airports in the United States. 5,170 of these airports are open to the general public and 503 of them serve commercial flights.

A great deal of flights within the USA are domestic flights as North America is over 9,826,675 km² in total which would be a considerable amount of driving if you were to travel by car. This contributes to a large amount of air travel travellers through the popular and smaller airports.

These are the Top 30 busiest airports by passenger numbers in the US for 2019:
