IATA (International Air Transport Association) conducts all international flights and almost all international airlines (94%) operate under this association. The pricing structure and all other decisions associated with an international flight are made by the IATA. They don’t normally give permission to international airlines to lower their rates if other airlines are offering regular airfares.
