Ground and Air
Air transportation is used in reference to traveling by airplane. The advantages of air transportation is shorter travel times and in many cases more affordable means of traveling.

The most obvious are being used every day. Air transportation includes: Airplanes, Helicopters, Hot Air Balloons, Blimps, Rockets, Kites, Parachutes and Birds.
I think that the hot air balloon was not a transportation in old times. The wright brothers invented an airplane that looked a bit like a glider, so there are chances that the glider might be used for transportation.
The study of air flow is a part of aerodynamics. It would be studied and used by engineers to improve streamlining for instance.
examples of air transportation
Air transportation is less cost effective than truck transportation especially for smaller items. But air transportation has the advantage of speed of delivery.
The purpose of a device used to remove air from water lines is to ensure proper water flow and pressure by eliminating air pockets that can disrupt the flow of water.
