Do commercial jet airliners fly through the ozone layer what affects my this wave?

Mostly the commercial flights fly at the altitude of 10 - 12 km.

The range is in between the upper most part of the troposphere to the lower part of the stratosphere.

Since,

At this height,

The air is dense enough to generate the sufficient lift.

Since, the lift is generated due to the difference in the pressure of air, between the top and the bottom of the wing.

As we go beyond 15 km, where the ozone layer is present, the pressure of sir reduces at this altitude,

And, the plane are not able to fly at this, as,

the lift is not generated, due to reduced air pressure.
