About Airliner cruising altitude
Passenger jets usually cruise between 10 and 12 km, roughly 33,000 to 40,000 feet. Up there the air is thin and smooth enough to burn less fuel, and most weather stays below.
The outside air is far below freezing, often around -55 °C, and the air pressure is about a quarter of what it is on the ground. The cabin is pressurised to feel like a few thousand metres of altitude.
