As aircraft go higher the air becomes thinner reducing the energy required to push the aircraft forward
Normal planes go at 40,500 feet from ground.
If they are in the air so the answer is no, because if planes fly at high altitude and at high speed. It makes it alot difficult to get planes shot down.
Pressurization keeps the people alive.
You can't go to space in GTA SA. The planes can only go up in the air so high until you get pulled back down.
At high altitudes the atmosphere is less dense that at lower altitudes. This means that planes flying higher experience less drag (friction) than those lower down, so that means they can go faster.

So they go faster or slower.
planes are so big now so they can carry more people and more fuel so they can go farther carrying more people.
Planes fly high to get above the weather, and to avoid air traffic. For jet planes, certain altitudes, all quite high, afford more efficient flight conditions.
Planes take off so quickly because they have the ability to go at fast speed. The air flows off the leading edges and the pilots reduce drag in order to go faster.
Planes can go up to the STRATOSPHERE.
High-speed fighter planes have aerofoil-shaped wings.
