LIft is what causes an airplane to fly. If you look at the wings on a plane the top is curved and the bottom is flat. When the plane moves thru the air it causes in imbalance of air pressure between the top and bottom of the wing
the air moving over the curved top has to move faster than the air moving across the flat bottom ( curved+ longer , flat + shorter) This creates a lower air pressure on the top of the wing and a higher pressure on the bottom. THe pressure actually pushes the plane up from the bottom of the wings.

It's all about the wings and engines. When the plane moves forward, the engine beats so fast, it goes about 400 to 500 mph. When you want the airplane to stop, here's how you do it. Ever seen those folding kinda things on a wing of a plane (don't know what it's called)? It goes up and down, you know what I mean? When it pushes down, the plane tries to go to a stop since the air is being pushed back.
The tail is also very important. At the edge of the largest tail it also has those turning things. When it pushes to the left, the plane moves to the right, when it pushes to the right, it turns left. Get what I'm saying?
And to make the plane lift also has something to do with the tail, yet I'm not sure what. Try looking it up online.
Oh and ever get the feeling that for about a second the plane feels like it's falling? Well up in mid air, there's air pushing under the wings, and some parts of the sky has air holes, which causes the plane to drop about 20 to 50 feet down until air rushes back under the wings.

The wings produce lift by the air flowing over them at different speeds. The air flowing over the top of the wing moves faster than the air flowing under them. The faster moving air creates a low pressure area on the top of the wing and the slower moving air creates a high pressure area under the wing. The higher pressure under the wing lifts it into the air.

Thrust and lift. The engines push the plane forward (thrust) and the angle of the wings forces air down. Thanks to action/reaction, this provides lift and the plane flies.
Read the link "Iwannalapdance" provided below, about why the wing shape argument is actually a common myth.
A wing is a reaction engine first and foremost. Bernoulli's effect is an important secondary effect. Newton's third law is the reason a wing can fly.

The shape of the wing. The engines just cause thrust and move the plane forward. The forward motion makes air move around the wing. When the air flows around the wing, the shape of it causes lift by altering the air pressure around the wing making it lower on the top of the wing and higher underneath it. The higher air pressure underneath the wing pushes it up.
