An IATA Code is a three-letter designation used to identify airports and airlines around the world. Created by the International Air Transport Association, these codes help streamline communication and operations in the aviation industry. For example, the IATA code for Los Angeles International Airport is LAX, while American Airlines is represented by the code AA. IATA codes are essential for ticketing, baggage handling, and flight scheduling. They simplify travel logistics by providing a standardized way to refer to specific locations and carriers. This system enhances efficiency and reduces confusion for passengers and airline staff alike.
