Jet aircraft generally fly above FL300 (30,000ft) to maximise efficiency. Not just fuel efficiency but also to minimise flight time.

Why do jet airplanes fly at altitudes above 30000 ft though it takes a lot of fuel to climb that high?

Why do jet airplanes fly at high altitudes?
Jet airplanes fly at high altitudes because it is more fuel efficient. Flying at higher altitudes uses less fuel than flying at lower altitudes.
What level do most airplanes fly?
Commercial, jet engined aircraft, such as the 747, fly at approximately 40 000 feet. Propeller aircraft fly at lower altitudes
Jet airplanes fly in the?
Air
What are benefits for jet airplanes?
they fly
Jet airplanes flying great distances fly in the what?
ALL aircraft fly in the Troposphere regardless of distance.
What comes out of the airplanes when they fly?
Jet exhaust, which is now mostly hot air.
Why cant airplanes fly straight out of the atmosphere?
Airplanes use air for lift and for thrust. If there's no atmosphere, they can't fly. Even a jet engine needs to burn and compress air.
At what altitudes do jet planes fly?
It really depends on what the size of the jets. The Airlines fly from 32,000 to 38,000 feet.Normal Jet Planes fly at about 30,000 feetMilitary Jet planes fly anywhere from 100 feet all the way up to 80,000 (Some do go higher but those are for special occasions)
Which is faster a jet or Concorde?
This depends on the jet. Most modern jet fighters are supersonic, however the high altitudes capable by Concorde mean it can fly generally faster due to the thinner air.
Can a people really fly?
on airplanes yes... in space sort of... if you had a jet pack... but sadly people can't fly like birds yet. =(
What can you infer about the height at which jet airplanes fly based on the fact that their contrails form cirrus clouds?
Cirrus clouds only form at high levels, so jet plaanes fly at super high levels.
