A plane flys because the air flowing under the wing of the place is doing so at a greater rate of speed than the air flowing over the wing. It is called lift.

The curve in the wing makes the top of the wing longer than the bottom.Because air has to travel a longer distance in the same time to go over the wing than under it, the air flows faster over the wing. The higher speeds over the wing create a low pressure area, this is called the Bernoulli effect, and is what keeps planes in the air.

Whatelks is right. the curve on the top of the wing is greater then below it, creating a larger surface area, which causes the air to move faster over it, which makes it thinner and pushes the wing and aircraft up.

this is bcoz the airplane is made of aluminium..tht is thin nd lightweight metal...that and the airplane's winged structure makes it fly nd prevents it from falling.
