Freedoms of the air
The freedoms of the air, also called five freedoms of air transport, are a set of commercial aviation rights granting a country's airlines the privilege to enter and land in another country's airspace. They were formulated as a result of disagreements over the extent of aviation liberalisation in the Convention on International Civil Aviation of 1944, known as the Chicago Convention.[1] The United States had called for a standardized set of separate air rights to be negotiated between states, but most other countries were concerned that the size of the U.S. airlines would dominate air travel if there were not strict rules. The freedoms of the air are the fundamental building blocks of the international commercial aviation route network. The use of the terms "freedom" and "right" confers entitlement to operate international air services only within the scope of the multilateral and bilateral treaties (air services agreements) that allow them.

The first through fifth freedoms are officially enumerated by international treaties, especially the Chicago Convention. Several other freedoms have been added, and although most are not officially recognised under broadly applicable international treaties, they have been agreed to by a number of countries. The lower-numbered freedoms are relatively universal while the higher-numbered ones are rarer and more controversial. Liberal open skies agreements often represent the least restrictive form of air services agreements and may include many if not all freedoms. They are relatively rare, but examples include the recent single aviation markets established in the European Union (European Common Aviation Area), and between Australia and New Zealand.
