Busiest US airports

The busiest US airports in any year since 1990, by passengers, departures, destinations or freight. Pick one to see where it flies and how its routes changed, or browse them on the map.

The table shows the top 20 for the column you sort by. Load factor is passengers as a share of seats. Destinations counts airports with at least 12 departures to them that year (for all years, in some year), each counted once. A city is a BTS city market (New York is JFK, LaGuardia and Newark): its row adds up its airports, counts each destination once, and opens to list them. Freight is in short tons (2,000 lb). Hover over a number for the exact figure. What the columns mean. On the map, routes with fewer than 12 departures a year are hidden.
