Key Takeaways:

The Chicago Convention, signed 80 years ago in 1944, established the foundational principles for international commercial air transport and led to the creation of the International Civil Aviation Organization (ICAO).
It affirmed state sovereignty over airspace and introduced bilateral "Air Services Agreements," which define the "Freedoms of the Air" governing international flight rights (e.g., rights to overfly, refuel, or transport passengers).
A significant and lasting outcome is the "substantial ownership and effective control" clause, requiring airlines to be predominantly owned and controlled by nationals of their home country, which has fragmented the industry by hindering cross-border 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.
