Browse US airports by state
All 50 states, the District of Columbia, and US territories, pick a state to see its full list of public-use airports.
How the directory is organized
AirportIQ HQ is organized first by state because that is how most travelers and planners actually think about US airports. When you ask "what airports does Montana have?" you do not really want a list of every helipad and grass strip, you want the public-use airports a traveler or charter operator could plausibly use, with their codes and classifications laid out cleanly. That is what every state page on this site delivers.
Within each state, airports are sorted by class, large_airport first, then medium, then small and regional. The class shown for each airport is the value the OurAirports CSV records in its type column.
If you would prefer to browse by FAA region rather than by state, the FAA regions index groups states the way the federal regulator does.
