What is the term for the right to fly over another country without landing?

The term for the right to fly over another country without landing is known as the first freedom of the air. This freedom specifically allows airlines to overfly a foreign country without the necessity to land there. It is a fundamental part of international aviation agreements, as it enables airlines to create more efficient flight routes without incurring the need for additional landing rights or regulations associated with landing in each country they fly over.

The first freedom is often considered foundational in bilateral air treaties, facilitating easier and more extensive air travel. Understanding this concept is crucial for those studying aviation management and international transport regulations, as it highlights the basic rights that countries grant to each other regarding airspace use.
