About FlyCodes
FlyCodes is a fast, free lookup for airport and airline codes. Type a code, a city or an airline name and get the answer straight away, with no sign up.
Why we built it
Looking up an airport code should take one second. Too many existing references bury the answer under clutter or dated interfaces. FlyCodes keeps the lookup at the top of every page and puts the code, its meaning and where it is right in the first screen.
What is covered
We cover 8,803 airports and 1,108 airlines from open datasets. Every airport and airline is reachable through search and available as a JSON endpoint. The busiest airports get full reference pages first, and the coverage of full pages grows over time.
Open data, open API
Everything is built on public datasets, credited on our data page. The API needs no key and has no rate limit, and you can embed a lookup on your own site with the widget.
Who builds and maintains it
FlyCodes is built and maintained by FusionStudios, a web studio in the Netherlands run by Jamey Weber. The dataset is regenerated from the upstream sources rather than edited by hand, and the date of the current copy is printed on every page built from it (this copy: 3 July 2026). How each figure is computed, and what it deliberately does not measure, is written out on the methodology page.
Found an error?
Tell us through the contact form, with the code and what you believe is wrong. Corrections that hold up against the source datasets go into the next regeneration, and errors that come from the source are reported upstream so everyone gets the fix. Route and carrier data is a historical open snapshot, so a carrier listed on a route may no longer fly it; that is a limitation of the source, and it is labelled on the pages that use it.
Independence
FlyCodes is an independent project and is not affiliated with, endorsed by, or connected to IATA, ICAO, or any airline or airport. Always confirm safety-critical information against official sources.
