to take people were they need to go and so they wont hit houses and other things.
most commercial airplanes fly from 35,000 feet to 45,000 feet above sea level.
Oh, isn't that a lovely question! Jet airplanes usually fly at an altitude of about 10 kilometers above the ground. That's around 33,000 feet up in the sky, where they soar peacefully like birds in the clouds. Just imagine the beautiful views they must see from up there!
The layer of the atmosphere where airplanes can generally fly is the stratosphere, which extends from about 10 to 50 kilometers above the Earth's surface. Most commercial airplanes fly in the lower part of the stratosphere, around 10-15 kilometers above the ground, where the air is thinner and there is less turbulence.

Anywhere from just above ground level to 1000 feet.
All commercial aircraft can fly low. That is how they line up for a landing . However, each type has a minimums factor of which is it speed and staff. If the pilot maintains these they can fly at low levels but doing so can cause high fuel burn, potential ground strike, hazard building factors including high reach cranes and towers
up to 60 mph. they can fly as high as 1000 feet above the ground
Where air planes fly, the temperature is below freezing.
Most fly between 30,000 and 50,000 feet.
Airplanes dont fly in the stratosphere because they produce too much sound. This may cause noise pollution and stress among people who are on the ground. So they dont fly in the Troposphere.
In order to fly, airplanes use aerofoil-shaped wings. An aerofoil is a shape that forms higher pressure beneath than above, pushing the plane up. The engine helps to accelerate the aircraft to a high enough speed to overcome gravity.
The fact that jet airplanes' contrails form cirrus clouds suggests that they fly at altitudes where the temperature and humidity are conducive to contrail formation, typically above 20,000 feet. This indicates that jet airplanes generally fly at high altitudes, where the air is colder and less dense, allowing contrails to persist and spread out into cirrus clouds.
