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

Explanation:

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 .
