Why do modern commercial airplanes fly at such high altitudes like 35,000 feet?
Why do passenger planes climb miles into the atmosphere instead of flying lower where the air contains more oxygen? How does it save jet fuel?

The air at 35,000 feet is extremely thin. This dramatic drop in atmospheric density significantly reduces aerodynamic drag on the airplane body, allowing it to fly faster while consuming far less fuel.
