The freedoms of the air (9 rights) are a set of commercial aviation rights granting a country’s airlines the privilege to enter and land in another country’s airspace. 

• The Freedom of air was formulated in the Convention on International Civil Aviation of 1944, known as the Chicago Convention. 
• The fifth freedom of air includes the right to fly between two foreign countries on a flight originating or ending in one’s own country.  
• The sixth freedom of air includes the right to fly from a foreign country to another while stopping in one’s own country for non-technical reasons.
