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.
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
Airplanes often fly at great altitudes, of 10 kilometers or more. People would have serious trouble breathing at that altitude.
Because cats do not have the capability to fly airplanes.
Because people are not able to fly without a airplanes.
You are unable to fly airplanes, however you can fly helicopters.
airplanes can not but satellites can
If an airplanes engines fail in flight, the plane can glide for a distance ( depending on it's altitude ), but gravity will eventually bring it down.While most manned airplanes have engines,there are a variety of airplanes that are designed to fly without an engine:sailplane, hang glider, paraglider.Such aircraft can theoretically stay aloft indefinitely in several ways:* towed by a ground vehicle or a powered aircraft* tethered to the ground, with wind (like a kite)* taking advantage of updrafts and ridge lift to gain altitude
