What are IATA codes primarily used for?

• A. Three-letter codes used for passenger and airline use.
• B. Four-letter codes used for flight planning.
• C. Numeric codes used for baggage handling.
• D. Used only for cargo.

Answer: (A)

IATA codes are three-letter identifiers assigned to airports that are used in everyday travel and airline operations. They appear on tickets, boarding passes, itinerary displays, and baggage tags, and are used by reservation systems and airline staff to quickly and consistently identify the right airport. This makes communication and handling smooth for passengers and airlines alike.

These codes are designed for practical, high-volume use by travelers and commercial operations. They differ from four-letter ICAO codes, which are used for technical tasks like flight planning and air traffic control. IATA codes aren’t limited to cargo; they cover the airports that serve passenger travel as well, making them the practical go-to in most Passenger-facing contexts.
