Air corridors refer to designated routes that aircraft can safely navigate through in the airspace. The term can also be interchangeably used with other synonyms such as airways, flight paths, flight lanes, and skyways. Air passages are another commonly used term that refers to these routes. These synonyms are used by air traffic controllers and pilots to communicate with each other and ensure a smooth and safe flow of air traffic. At times, air corridors may cross international borders and become known as international airways. Regardless of the term used, air corridors play a crucial role in the aviation industry and allow for efficient air travel worldwide.
