The International Air Transport Association, or IATA, is a trade association of airlines that represents approximately 290 airlines worldwide. Founded in 1945, IATA plays a crucial role in the aviation industry by setting global standards for airline safety, security, efficiency, and sustainability. It also provides support and training for airline operations and management. IATA is known for its role in developing the IATA Airport Code system, which assigns unique three-letter codes to airports around the world. This system simplifies travel logistics and enhances communication within the airline industry, making it easier for passengers and airlines alike to navigate air travel.
