When watching a commercial aircraft traverse the sky from the ground below, they can often look so tiny with how high they are in the atmosphere. On average, aircraft traverse at an altitude of 36,000 feet, placing themselves at a height that requires pressurized cabins to keep passengers safe and comfortable. With the extreme atmospheric temperatures, high pressure differences, and lack of breathable air at the altitude at which commercial airplanes fly, one may wonder why this is the standard. Despite all of this, flying at a height between 33,000 and 42,000 feet is actually highly beneficial, promoting fuel efficiency, hazard prevention, safety, and much more.
