FAA sets the rules.
They're designed to reduce collisions.
East flies at odd-000 feet
and West flies at even-000 feet up to 29,000, then they alternate every 2,000 feet. With better radar, better computers, and onboard collision avoidance equipment, controllers are able to reduce the vertical separation and accommodate more aircraft They fly at a specific altitude because the airlines save money on fuel if they fly between 33-42,000 feet. The air is thinner here and the plane uses less fuel to fly from one distance to another.
36,000 feet
One of the main reasons is to conserve fuel. Airplanes can fly at any altitude and speed. However, airplanes generally tend to fly at high altitude to conserve fuel. This makes the plane more efficient and keeps the operating cost down. Of course, an airplane can not always fly at max altitude at every flight. It may have too much weight or the distance it travels may be too short. So there is always a trade-off as to how they will fly the route.
A Boeing 737 Maximum Altitude ranges from 35,000 feet (-100 and -200 series) to 41,000 feet (-600, -700, -800, -900ER). Airplanes do not usually fly at their maximum capable altitude, they tend to fly a couple of thousand feet below that, low 30's.

At cruising altitude most airplanes are at between 35,000 and 41,000 feet. However, to get there it has to pass all of the intervening feet between that and the altitude of the airport.
Most prop planes fly any where from 1,000-5,000 ft. Airliners usually fly from 10,000-20,000 ft. Military jets fly at pretty much any altitude
Because cats do not have the capability to fly airplanes.
Airplanes often fly at great altitudes, of 10 kilometers or more. People would have serious trouble breathing at that altitude.
Because people are not able to fly without a airplanes.
You are unable to fly airplanes, however you can fly helicopters.
They usually fly in the stratosphere. That is from 25,000 feet to 40,000 feet. This may differ from palne to plane. A plane like Cessna flies very close to the ground at about 9000 feet.
airplanes can not but satellites can
