I may be wrong, so anybody else reading this please let us know. However, I believe the reasons for higher altitude flight are several fold. First there is the concern of noise. The farther the distance from the ground the less amount of sound will reach the ground. Next is basic science or physics. If one knows about air fuel mixture principles, like in automotive applications where carborators & fuel injection systems attempt to maintain a 14:1 ratio of air to fuel at ground level. Then it might stand to reason that at higher altitudes where the air is thinner(less dense), that less fuel may be required to maintain proper air fuel ratios. Then there is also the issue of wind resistance. Again, at higher levels from the ground the air is thinner, giving less friction(resistance) to the air surfaces(including wings) of the entire aircraft. This would also cause the need for less fuel and allow further distances and speeds than at closer to earth heights. Thanks for listening.
