The travel guide to every US airport, including the regional ones the big sites skip.

What is AirportIQ?

AirportIQ is a structured travel reference for the United States aviation system, with a deliberate emphasis on the regional and secondary airports that the big-name travel sites tend to skip. Every page on this site is built from public records, primarily the Federal Aviation Administration's NASR Airport Master Record (Form 5010), ICAO identifiers, and the OpenFlights global airports release, so the facts you read about a runway length or an IATA code match the official sources used by pilots, dispatchers and travel desks.

If you have ever tried to confirm whether a small regional field has scheduled passenger service, or whether a city has a single airport or several, you know how scattered the answers usually are. We collapse that into a consistent template: each airport gets the same fact table, the same contact and code panel, the same parking and ground-transport block, and the same set of likely connecting carriers, so you can move from one entry to the next without relearning the layout.

What's different about AirportIQ? We index every public-use airport, not just the 30 names you can already book on a fare-comparison site. That means you'll find small regional fields here that are the actual closest commercial airport to many travelers but never get a page anywhere else.

Who AirportIQ is for

This site is built for three kinds of readers. The first is the everyday traveler who just needs to know whether their flight leaves from a large hub, a medium-size regional airport, or a small commuter strip, and what airlines they should expect to see at the gate. The second is the planner: corporate travel managers, charter coordinators, and small-business owners who want to compare airports inside the same metropolitan area or state at a glance. The third is the aviation enthusiast, student pilots, ATC trainees, and writers who simply want a clean reference that does not bury the codes behind ten interstitial ads.

How to use the directory

Start with the search bar in the header and try anything: an IATA code like SEA or BOI, a city name like Bozeman, an airline like Frontier, or even a partial airport name. You can also drill in geographically with the browse-by-state grid above, by FAA region, or sort airports by class on the all airports index. Every link on this site leads to a fully built reference page, there are no dead ends and no placeholder templates.
