Chicago O'Hare's code ORD comes from its original name — Orchard Field, a former Douglas aircraft factory airstrip. This 50-question quiz challenges you to match IATA and ICAO codes to their airports, uncover the surprising origins behind codes like MSY, LAX, and YYZ, and test your knowledge of the world's busiest hubs.
Chicago O'Hare International Airport uses the code ORD because the site was originally called Orchard Field (later Orchard Place), a Douglas aircraft factory during World War II. When it became a commercial airport and was renamed after Medal of Honor recipient Edward "Butch" O'Hare, the original ORD code stuck.
IATA stands for the International Air Transport Association. Founded in 1945, it assigns the familiar three-letter codes (like JFK, LHR, SYD) used on boarding passes, luggage tags, and flight booking systems worldwide.
IATA codes are three letters used commercially (e.g., JFK, LHR). ICAO codes are four letters used by air traffic control and flight planning (e.g., KJFK, EGLL). ICAO codes include a regional prefix: K for the contiguous US, C for Canada, EG for the UK, and so on.
