👉 Airline fluid, often referred to as "air traffic flow," is a concept that describes the movement and interaction of aircraft within the controlled airspace around airports. It encompasses the dynamic processes governing the scheduling, routing, and spacing of flights to ensure safe and efficient operations. This fluidity is achieved through a combination of air traffic controllers' precise management, advanced radar and communication systems, and adherence to international aviation regulations. By maintaining a smooth flow of air traffic, airlines can minimize delays, reduce fuel consumption, and enhance passenger experience.
