Flight routes are the specific paths that airplanes take when traveling from one airport to another. These routes are carefully planned to ensure safety, efficiency, and to avoid obstacles like mountains or restricted airspace. Airlines use these routes to optimize fuel consumption and reduce travel time for passengers. Air traffic control plays a crucial role in managing flight routes. They provide pilots with instructions and updates to ensure that flights remain on course and maintain safe distances from other aircraft. Factors such as weather conditions and air traffic can also influence the chosen flight route, making flexibility important for successful travel.
