How Many Airports in The United States of America USA? The United States is home to a vast number of airports, supporting one of the busiest aviation networks in the world. There are over 13,000 airports spread across the country, but they vary greatly in size, purpose, and accessibility. Roughly 5,000 of these are public-use airports, which include everything from major international hubs to smaller regional airports serving more localized travel. Major airports like Atlanta’s Hartsfield-Jackson, Chicago O’Hare, and Los Angeles International (LAX) handle millions of passengers each year, acting as key international gateways and hubs for domestic travel. In addition to public-use airports, there are over 8,000 private-use airports scattered across the country, primarily serving smaller, private flights and cargo operations. The vast number of airports in the U.S. reflects the country’s large land area and its high demand for air travel, making air transportation a crucial part of American infrastructure and economy.
