Airports and flight routes by state

See every tracked airport in a state side by side, with the busiest routes they serve, which airports share them and the flight CO2 per passenger on each, using 2025 flights.

Why only these states

A state page has to add something its airport pages don't. So a state gets one only when at least 2 of its airports have their own page, and together they cover at least 4 routes beyond what the busiest one covers alone (an airport covers a route when it carries at least 5% of its passengers). Right now that's California, Florida and Texas.

Which state an airport is in comes from Wikidata, retrieved 2026-11-06. A city's airports can sit in a neighbouring state, so each airport is placed by its own location, not by the city it serves. The airport index lists every airport this site tracks.
