Third, IATA avoids duplication of codes to prevent confusion among airlines and passengers. The codes must also be simple for travelers to recognize and remember.
Fourth, once IATA approves the request, they assign the code. Subsequently, the code becomes part of the airport’s identity and is used in ticketing, scheduling, and baggage handling.
