The planes fly in the Stratosphere. Ozone layer is also there.

Most passenger airplanes fly in the stratosphere. Planes like Cessna fly near the troposphere. It depends on the size and sound of the planes.
because of weather phenomena
Air planes fly in the stratosphere. Sorry, i didnt give the info of why they fly..im so dumb
Planes can fly fifty feet off the ground if they need to. Commercial airliners fly in the stratosphere for two reasons: there's very little general aviation traffic up there (and most of the GA guys with planes who can fly that high are good pilots), and the plane is more efficient at that altitude.
Most commercial jet liners fly in the stratosphere. Some military aircrafts fly higher than that. Small planes fly lower than the jet liners.
The air molecules in the stratosphere are far apart. This causes less wind resistance and allows planes to fly faster and achieve better fuel economy.
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.
