Most commercial jet liners fly in the stratosphere. Some military aircrafts fly higher than that. Small planes fly lower than the jet liners.
To avoid turbulence, most commercial jets fly in the upper layer of the troposphere, which varies in height depending on latitude, typically 40,000 feet (5 km). This is on the border of the tropopause, just above the troposphere, and the lower layer of the stratosphere in some cases.
They generally fly in the troposphere at lower levels and the stratosphere while cruising, which are the first and second sections of the atmosphere. The begining of the stratosphere can start at varying levels. At the poles you can hit it as soon as 7000 meters, so often planes will fly into this second layer of our atmosphere.
A jet stream is a region of strong winds high in the atmosphere where planes fly. If she flies a plane into this region, the plane will be accelerated. This will allow her to either fly faster, or fly at the same speed using less fuel.
Planes fly better in warm weather because if it is cold then fog builds up and they want be able to see also the wind will be pushing them back so its better to fly in warm air.
Humans weigh too much and can't run fast enough to fly. But they have minds to be able to build planes that can allow them to fly.

They can fly but they have a high chance of getting damaged.
Most planes fly in one layer of the atmosphere called the troposphere. High flying aircraft can fly into the stratosphere
by using lots of fuel and by going very fast.
Airplanes fly inside the atmosphere which is made up of 4 levels. The atmosphere starts at sea or ground level and when it ends you are in outer space (no longer on earth). Majority of all planes fly in the first level of the atmosphere called the Troposphere which ends around 50K feet. Military jets and spy planes usually fly in the second atmosphere called the stratosphere.

Planes are not perfect but they are not the worst to fly in because it can be safe but it cant be sometimes most of the time it is great to fly in so most of the time planes are safe.
Itβs 45,000 ft for commercial airliners

Most passenger airplanes fly in the stratosphere. Planes like Cessna fly near the troposphere. It depends on the size and sound of the planes.
Of course, planes can fly.
