What are the advantages of airplanes flying so high?

If it’s because of wind tunnels that helps push the planes faster, how much slower would they be if they weren’t in those wind tunnels?
If the average flight from NY to London is 7H and 10M what would the flight time be?

No, it’s not the wind tunnels (or jet stream). Because those things, if you happened to catch one, will only help you in one direction. Like maybe flying from NY to London it pushes you along faster, but flying back from London to NY and it slows you down.

It’s because the air is less dense up high, meaning there is less wind resistance, less drag, meaning you can fly your plane faster and be using less fuel than if you were flying lower in the thicker air.

Imagine it like this: flying up high is like running on land just moving through the air. Pretty easy. Flying low is like running through a pool, that thicker, denser, water makes it much harder for you to move.
