Why Do Airplanes Need To Fly So High?

Commercial airplanes fly at high altitudes, typically between 32,000 and 38,000 feet, to reduce air resistance and improve fuel efficiency. The thin atmosphere at these heights decreases drag, lowering fuel consumption and operating costs. Additionally, flying high provides a safety cushion, allowing pilots more time to address potential issues. High altitudes also offer more stable air, reducing turbulence and avoiding ground structures. This ensures a smoother and safer flight experience for passengers.
