I hope I convey my point probably, but why do planes go so many thousands of feet in the air? Is it faster that way, or could they achieve similar flight times at a lower altitude?
Does it have something to do with the curvature of the earth?

True ELI5: the air is thinner higher up. That means that an airplane has to work less hard against the air to actually do the travel.
