What is the difference between IATA and ICAO airport codes?

• A. IATA codes are three letters used for ticketing and baggage, while ICAO codes are four letters used for air traffic control and flight operations.
• B. IATA codes are four letters used for ATC; ICAO codes are three letters used for tickets.
• C. IATA codes are two letters used for passenger manifests; ICAO codes are five letters used for weather.
• D. IATA codes are three letters used for navigation; ICAO codes are six letters used for flight crew.

Answer: (A)

Two coding systems exist to serve different parts of aviation: passenger-facing information and operational navigation. IATA codes are three-letter designations that airlines and airports use for tickets, baggage tags, and public timetables. They’re designed to be memorable and easy for travelers, so you’ll see LAX for Los Angeles, JFK for New York, CDG for Paris, and so on. ICAO codes are four-letter identifiers used by professionals for air traffic control, flight planning, and official data exchange. They’re globally standardized and embed regional information, with a typical structure that includes a regional prefix (in the United States, for example, the codes start with K, so Los Angeles is KLAX and New York is KJFK; Paris would be LFPG). So, the three-letter IATA codes cater to ticketing and baggage, while the four-letter ICAO codes support ATC and flight operations.
