Pressure below the wing is higher, causing air to rush upwards, trying to get above the wing, causing lift.

How do planes stay up?
Lift pushes the airplane up. The way air moves around the wings gives the airplane lift. The shape of the wings helps with lift, too.
What makes an airplane lift up into the air?
The air under the plane's wings exerts pressure.
Can an airplane stay in the sky?
I am going to assume that aeroplane=airplane when I answer this. An airplane stays in the air by generating lift on its wings. As long as an airplane can generate sufficent lift it can stay in the air. However once the lift being generated falls below what is required for the plane to stay up... uh oh.
What holds an airplane up?
lift
How are lifts and thrusts used on an airplane?
Lift and thrust is what enables an airplane to maintain flight. Lift is generated by the wings, and thrust is generated by the engine or propeller. Combined they enable the aircraft to fly. Air currents and up-drafts, on an aircraft that does not have an engine (like a glider), also help generate lift and thrust to keep such an aircraft in the air. However, gliders get into the air by being towed by an airplane, or by a sort of sling-shot.
What keeps an airplane up in the sky?
Bernoulli's Principlethe statement that an increase in the speed of a fluid produces a decrease in pressure and a decrease in the speed produces an increase in pressureWind has nothing to do with how an airplane stays in the air. In actuality, an airplane flies better on calm days than on windy ones! It is the act of lift, weight, thrust and Bernoulli's principle (though this principle isn't all that true, since airplanes are able to fly upside down and a model airplane with non-airfoil shaped wings can stay in the air just fine) that determines how an airplane is able to stay in the air.an airplane stays up in the air by the pressure above and below the wings...There is actually more than one force that enables an airplane to stay in the air: that is lift, weight and thrust. Weight has to be less than the force of lift and thrust combined to both get the airplane into the air and keep it in the air.
Can a tornado lift up a airplane?
Yes, it can.
What force pushes an airplane wing up?
Lift
What does lift do to the airplane?
Lift acts against the force of gravity, pushing the aircraft up.
How does an airplane get lift during take off?
As the airplane speeds up the air flowing around the control surfaces speeds up as well. When this happens the horizontal stabilizer is deflected into the wind causing the nose of the aircraft to rise. As the nose rises the angle of the wings also increases and create lift by 'air deflection' and 'bernoullis principle'. Many other factors are involved to create lift, these are just the main principles.
How is the airplane flies?
High air pressure builds up under the wings, and low air pressure goes over the wing, and that makes lift. Thrust from engine pushes it forward.
Why do airplanes stand up?
The quick answer is that the engines on the airplane is design to push air straight backwards this makes the airplane accelerate straight forward. When the airplane wants to lift whe have to get a force that pushes it upwards(or else it would not lift). The upwards force comes from two major sources, by the air pushed down by the wings(which also are pointing upwards and therefor pushes down the air that passes under them) and by the engine that is pointing downwards.
