An airport is a building that operates as a hub for the movement of people, cargo, and airplanes. It generally consists of runways for planes to take off and land, a terminal building for passengers to check in and wait for their flights, and a control tower to correspond to the movement of airplanes on the ground and in the air.

Some of the biggest airports in the world are located in major cities and serve as crucial hubs for global travel. Airports can also be found in smaller towns and as regional carrier centers. In addition to providing a means of travel, airports can also be significant economic drivers for the areas in which they are located.
