The 1940s created the international legal and institutional architecture that still shapes air transport. The 1944 Chicago Conference led to the Convention on International Civil Aviation and the establishment of the International Civil Aviation Organization (ICAO), which set common principles for sovereignty over airspace, safety standards, and technical cooperation among states. Associated agreements on transit and traffic rights—the “freedoms of the air”—provided a framework for negotiating bilateral air services, balancing national interests with the need for international networks.
Parallel economic and industry bodies also emerged. The Civil Aeronautics Board in the United States assumed comprehensive control over domestic routes, fares, and entry, embedding a public‑utility model of airline regulation that would last for decades. Internationally, the International Air Transport Association (IATA), formed from earlier trade associations, became a forum for airlines to coordinate fares and conditions on international routes under government oversight, helping to stabilize pricing and service standards in a regulated environment. Together, ICAO, IATA, and national regulators created a rules‑based global system that prioritized safety, financial stability, and orderly growth over competition.
