Key Takeaways:

The Chicago Convention, signed 80 years ago, established the foundational principles for commercial air transport and led to the formation of the International Civil Aviation Organization (ICAO) to coordinate global aviation norms.
It codified state sovereignty over airspace, necessitated bilateral "Air Services Agreements," and introduced the "Freedoms of the Air" that govern international flight rights.
A significant "Ownership and Control Clause" within these agreements requires airlines to be substantially owned and controlled by nationals of their home country, which has historically fragmented the market and hindered cross-national mergers.

Last week, commercial air transport celebrated an important milestone in its history. Exactly 80 years ago, on December 7, 1944, at the Stevens Hotel in Chicago, 52 states signed the Chicago Convention, the document that established the general principles regulating commercial air transport up to this day.

The convention became effective on April 4, 1947, when it was ratified by the 26th signatory country, and later that year the United Nations formed the International Civil Aviation Organization (ICAO), a specialized agency responsible for the international coordination of all norms and principles regulating air transportation across the world.
