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.

What altitude do airplanes fly at over Greenland?
36,000 feet
How do airplanes change altitude?
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.
Can airplanes or satellites fly in the thermosphere?
Yes, airplanes cannot fly in the thermosphere due to the extremely low air density at that altitude. Satellites do not fly in the traditional sense but orbit within the thermosphere, taking advantage of the lack of air resistance.
What part of the atmosphere do airplanes fly?
Airplanes fly in the troposphere, which is the lowest layer of Earth's atmosphere. This layer extends from the Earth's surface up to an average altitude of about 11 kilometers (7 miles).
What layer do the airplane fly?
Airplanes Fly in the layer of the atmosphere called Troposphere
What altitude does a Boeing 737 fly at?
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.
What altitude does a Boeing 737 fly?
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.
How many feet does an airplane fly at?
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.
What elevation do airplanes fly?
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
Why do cats not fly airplanes?
Because cats do not have the capability to fly airplanes.
Why are aeroplane cabins pressurized?
Airplanes often fly at great altitudes, of 10 kilometers or more. People would have serious trouble breathing at that altitude.
Why does a person fly in airplanes?
Because people are not able to fly without a airplanes.
