Planes start out in the lowest layer, the Troposphere, and may stay in this layer for Short Haul trips. For longer trips, they climb to the Stratosphere, as this is above the main weather (clouds in particular), and there is less air resistance, so they burn less fuel.
However, the higher aircraft go, the less oxygen there is in the atmosphere, so there is a limit to the height at which normal jet engines function. Concorde had special engines which accelerated the incoming airflow at high altitudes to help overcome this. The extra heat generated by the air friction at supersonic speeds and by increased cosmic radiation at higher altitudes caused difficult engineering challenges - the aircraft expanded by several centimeters when at full speed!
Pilots will try to fly at altitudes where the winds are blowing in the direction they are travelling, as this can lead to significant savings in fuel and time. They will request altitude changes if the weather changes.

Airplanes fly through troposphere.

THE SECOND LAYER ITS THE STRATOSPHERE
