Airport codes are unique identifiers assigned to airports around the world. These codes typically consist of three letters, known as IATA codes, which help travelers and airlines easily recognize specific airports. For example, Los Angeles International Airport is represented by the code LAX, while John F. Kennedy International Airport in New York is represented by JFK. In addition to IATA codes, airports also have ICAO codes, which are four-letter alphanumeric codes used primarily for air traffic control and flight operations. For instance, the ICAO code for LAX is KLAX. These codes streamline communication and enhance safety in the aviation industry.
