International Air Services Transit Agreement Members: An Overview

The International Air Services Transit Agreement (IASTA), also known as the Two Freedoms agreement, is a treaty between countries that enables airlines from one country to fly over or stop in another country without the need for prior permission. The IASTA was signed in 1944 as part of the Chicago Convention on International Civil Aviation and has since been ratified by numerous countries across the world.

As of 2021, there are 136 IASTA member countries. These countries have agreed to grant the following two freedoms to each other’s airlines:

1. First Freedom: The right to fly over another country without landing.

2. Second Freedom: The right to make a non-commercial stop in another country for refueling or maintenance purposes.

In addition to these two freedoms, the IASTA also grants the following additional freedoms:

3. Third Freedom: The right to fly from one`s home country to another country.

4. Fourth Freedom: The right to fly from another country to one`s home country.

5. Fifth Freedom: The right to fly between two foreign countries while stopping in one`s own home country.

6. Sixth Freedom: The right to fly between two foreign countries while stopping in another foreign country.

While IASTA member countries have agreed to grant the above freedoms to each other’s airlines, there are still restrictions and regulations in place. For example, countries may limit the number of flights or routes that foreign airlines can operate within their territory, or they may require airlines to obtain specific permits or licenses.

Nevertheless, the IASTA has contributed significantly to the growth of international air travel and has facilitated the global connectivity of economies, cultures, and people. It has also enabled airlines to expand their networks and offer more options to passengers.

In conclusion, the International Air Services Transit Agreement (IASTA) is a crucial treaty that allows airlines to operate across borders without unnecessary bureaucracy. As of 2021, there are 136 IASTA member countries, all of which have agreed to grant certain freedoms to each other`s airlines. While there are still regulations in place, the IASTA has undoubtedly contributed to the growth and facilitation of international air travel.
