Generally yes. There is less drag at higher altitudes, and thus better fuel economy, right up until the airplane can't get enough air to burn with with fuel to get the power needed to go faster and higher. Of course it takes extra fuel to get up there, so only long distance travel is done at high altitudes.
faster in higher altitiudes
The airplane may succumb to the power of gravity as lift decreases at higher altitudes.

The density of air decreases at higher altitudes.
because there is low pressure at higher altitudes
Hot Air Ballons Travel at Low Altiudes Because If it goes any Higher it could pop.
Of course airplane heights are safer than mountain heights. Mountain heights are extremely dangerous and really scary but airplane heights are more higher altitudes. Airplane heights are not that scary also it is much safer than mountain heights.
Yes.
Mountain passes gave traveling settlers a way to travel through the mountains. Without the passes, the settlers would have to travel to higher and more dangerous altitudes.
They have cooler temperatures than places at lower altitudes.
