The IATA Airport Code is a three-letter designation used to identify airports around the world. These codes are assigned by the International Air Transport Association and help streamline air travel by providing a standardized way to refer to airports. For example, the code "JFK" represents John F. Kennedy International Airport in New York City. IATA codes are commonly used in flight itineraries, tickets, and baggage tags, making it easier for travelers and airlines to communicate about specific locations. Each code is unique to its airport, ensuring clarity and reducing confusion in the busy world of air travel.
