The airport code quiz with a map
Three-Letter Club is a free game to learn 3-letter airport codes (IATA codes) and where each airport is. Flashcards teach you that ORD is Chicago O'Hare. Here you also find it on the map, so the code, the city and the place stick together. As far as we know, it is the only airport code quiz that trains you on a map.
Three ways to play
- Learn the codes: a city appears, pick its code among three look-alikes. 60 seconds, as many as you can.
- Learn the map: a code appears, tap its airport on the map. Three tries per airport.
- Become an expert: type each code from memory against the clock, just like a real test.
Built for
- Airline and airport staff: gate and ramp agents, flight attendants, dispatchers, ground handling and cargo teams who read station codes all day. Pick your home station and compete with your colleagues.
- Anyone with a city code test coming up: airline training, travel agent courses, aviation school. Four levels (Take-off, Cruising, Turbulence, Diabolic) go from the big hubs to the codes with a secret, each code comes with the story behind it, and Practice my mistakes replays only what you missed.
- Quiz addicts: 60-second rounds, streaks that raise the pressure (trickier answers, more points), personal records, passport stamps, a Diabolic level for twins and neighbours like MSY / MCI or SJC / SNA, monthly leaderboards and a spoiler-free score to share.
What you will learn
150+ airports: the main US airports and major hubs, Alaska's bush stations on their own Alaska map, Hawaii, Canada, Mexico and Central America, plus the big international hubs such as London Heathrow (LHR), Paris Charles de Gaulle (CDG), Tokyo Narita (NRT) and Sydney (SYD).
Questions
What is an airport code?
An airport code (IATA code) is the three-letter code printed on boarding passes and bag tags, such as LAX for Los Angeles or ANC for Anchorage. Airlines, airports and travel agents use them every day.
What is the fastest way to learn airport codes?
Short, daily rounds work best. Start with the big hubs, then the codes that follow the name, then the codes with a secret, and finally the twins that look almost identical. Placing each airport on a map gives your memory a second hook, and replaying only the codes you missed closes the gaps quickly.
Can I use it to prepare for an airline or airport job test?
Yes. Many airline, ground handling and travel jobs ask new hires to know city and airport codes. The Expert mode makes you type each code from memory, like a real test, and Practice my mistakes replays only the codes you got wrong.
Which airports are in the quiz?
More than 150 airports: the main airports of the USA (including many Alaska stations and Hawaii), the major US hubs, Canada, Mexico, Central America and the biggest international hubs in Europe, Asia, Africa, South America and Australia.
Is Three-Letter Club free?
Yes. It is free, works in any browser on phone or computer, needs no account and works offline once installed. A free player profile (nickname and PIN, no email) adds you to the monthly leaderboards.
