I think the maximum flight level for commercial passenger airliners is 41,000 feet.
That's 12.5 kilometers above sea level.
The altitude above the ground depends on how high the ground is.
The highest ground on earth is the peak of Mt. Everest, about 8.9 km above sea level.
So the maximum flight level for a passenger jet is about 3.6 km higher than the highest
point on the ground.
because it is the layer where airplanes fly
1 kilometer = 100,000 centimeters So if it flies 80 kilometers every hour, it would fly 8,000,000 centimeters in an hour.
36 minutes. But, no bird on earth can fly at 500 km per hour.

Spacecraft and high-altitude aircraft, like spy planes or research aircraft, can fly in the thermosphere. These vehicles are specially designed to withstand the extreme temperatures and low air density in this layer of the atmosphere. Commercial airplanes do not fly in the thermosphere as they operate in the lower layers of the atmosphere.
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.
2,000 airplanes fly in the air each day.
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).
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.
Airplanes typically fly in the troposphere, which is the lowest layer of Earth's atmosphere. This layer extends from the surface up to around 12 kilometers (7 miles) in altitude.
a lot!
Because cats do not have the capability to fly airplanes.
It depends on the fuel capacity. Some airplanes can refuel during flight so conceivably, they can fly until the engines need maintenance. Current aircraft can fly up to 8,000 miles or about 14-15,000 kilometers.
Because people are not able to fly without a airplanes.
Small airplanes like Cessna can fly close to ground. This is because they dont cause much noise. But big airplanes like Boeing and other passenger planes are allowed to fly only in the stratosphere. They cause much noise.
You are unable to fly airplanes, however you can fly helicopters.
