As aviation leaders gather in Rio de Janeiro for the 82nd IATA Annual General Meeting (AGM) and World Air Transport Summit (WATS), they return to a city that occupies a unique place in the history of global aviation.
Rio was where, in 1999, IATA formally introduced the World Air Transport Summit, recognising that its annual gathering had evolved into something much larger than a trade association meeting. Aviation had become one of the defining industries of globalization, carrying more than 1.5 billion passengers annually and generating over $300 billion in revenues. The AGM had become the forum where airline leaders, governments, manufacturers, airports and regulators debated the future of an increasingly interconnected world.
Yet the story begins more than half a century earlier.
On 19 April 1945, representatives from 57 airlines across 31 countries met in Havana, Cuba, to establish the International Air Transport Association. Later that year, Montreal hosted the first AGM. The Second World War had not yet formally ended. Commercial aviation was fragmented, expensive and accessible to only a privileged few. Fewer than 10 million people travelled internationally by air each year. Airlines operated fleets of piston-powered aircraft carrying a few dozen passengers at a time, while industry revenues were measured in millions rather than billions of dollars.
The challenge facing IATA’s founders was deceptively simple: how do you create a truly global aviation system when every airline, airport and government operates differently? The answer would help shape the next eighty years of aviation and, in many respects, help shape the modern world itself.
Building the Rules of the Sky: 1945-1959
The first two decades of IATA’s existence were not defined by aircraft innovation, but by standardisation. Under Sir William Hildred, IATA’s first Director General, the organisation established many of the invisible systems that continue to underpin international aviation today. Common ticketing rules, interline agreements, settlement systems and operational standards allowed airlines from different countries to function as part of a single global network. Without those foundations, modern international travel would simply not exist.
The AGM locations during this period reflected the geography of aviation at the time. Meetings rotated between Montreal, London, Geneva, Paris, New York and other North American and European centres that dominated commercial aviation. Yet two meetings stand out in hindsight. New Delhi hosted in 1958 and Tokyo followed in 1959. At the time, these destinations were simply new additions to the AGM calendar. Looking back, they represented early signs of where aviation’s future growth would emerge.
The decade also coincided with the first major expansion of commercial aviation. Aircraft such as the Lockheed Constellation and Douglas DC-6 dramatically improved range and reliability, while governments increasingly recognised aviation as a strategic economic and diplomatic tool. When Hildred began his tenure, fewer than 10 million passengers travelled internationally each year. By the end of the 1950s, airlines were carrying around 100 million passengers annually worldwide and generating approximately $5 billion in revenues. Pan American World Airways, BOAC, Air France, KLM and TWA dominated the skies, while a new era was already taking shape…
