Extended data:

The International Air Transport Association is a large international organization composed of airlines from all over the world, and its executive body is located in Geneva. Compared with ICAO, which supervises aviation safety and navigation rules, it is more like an international coordination organization composed of carriers (airlines), which manages ticket prices and dangerous goods transportation in civil aviation transportation. Its main function is to coordinate and communicate intergovernmental policies and solve practical problems through air transport enterprises.
