Tips
- Type an airport name, city, country, or IATA/ICAO code into the search box — matches are filtered instantly and case-insensitively.
- Flight tickets and e-tickets usually show destinations as a 3-letter IATA code, so you can look up the airport from the code itself, not just the city name.
- Cargo and international mail slips sometimes use the 4-letter ICAO code instead, so having both codes side by side makes cross-checking easier.
- When a city has multiple airports (like Tokyo's Narita and Haneda, or Osaka's Kansai and Itami), searching by city name lets you compare all of them at once.
- Before a business trip, jot down the IATA codes of your connecting airports in advance so you can read local signage more quickly.
Frequently Asked Questions
The IATA code is a 3-letter identifier set by the International Air Transport Association, used on tickets and baggage tags. The ICAO code is a 4-letter identifier set by the International Civil Aviation Organization, used for air traffic control and flight plans. The same airport carries both, used for different purposes.
Cities like Tokyo (Narita/Haneda) or Osaka (Kansai/Itami) added a second airport over time as demand grew or to split international and domestic traffic. Always double-check the airport name, not just the city, when booking a flight.
The 3-letter IATA code is usually shown in the "Origin" and "Destination" fields of your booking confirmation email or e-ticket. You can also look it up here by searching for the city name.

Side Note — Trivia About Airport Codes
IATA codes are usually built from letters in the airport or city name, but not always in an obvious way. Chicago's O'Hare International Airport carries the code ORD because the airfield was originally called "Orchard Field" — a history that's hard to guess from the airport's current name.
ICAO codes assign a leading letter (or letters) by region, which makes the system a fun way to guess roughly where an airport is. Every airport in Japan starts with "RJ" (or "RO" for Okinawa), Europe mostly starts with "E", and North America starts with "K" or "C".
When a city ends up with multiple airports, it's usually the result of history splitting their roles. Tokyo's Narita International Airport was built to absorb growing international demand, while Haneda Airport (Tokyo International Airport) developed as the domestic hub closer to the city center. In recent years Haneda has taken on more international flights too, so the split of roles keeps shifting.
