Commercial airplanes cruise at high altitude because thinner air reduces drag and fuel consumption.

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that commercial airplanes cruise at high altitude because thinner air reduces drag and fuel consumption?

Yes. One aviation Q&A states directly that commercial jets cruise at high altitudes because thinner air reduces drag, improving fuel efficiency; two peer-reviewed studies add only that cruise flight level affects fuel consumption, without tying the benefit to reduced drag.
