Which freedom grants the privilege to carry revenue traffic between two treaty partner countries?

The Fifth Freedom of the Air specifically allows an airline to carry revenue traffic between two foreign countries while the airline is in transit between its home country and the destination country. This freedom provides the airline with the ability to pick up passengers or cargo in one foreign country and drop them off in another foreign country. The significance of this freedom lies in its ability to enhance international connectivity and expand market opportunities for airlines, allowing them to operate more financially viable routes.

In contrast, the other freedoms—First, Second, Fourth—focus on different aspects of air travel, such as the right to fly over a country without landing, the right to land only for technical stops, and the ability to carry traffic from one foreign country to the airline's home country, respectively. Understanding these distinctions is crucial for recognizing how international aviation agreements facilitate the movement of people and goods across borders.
