Flyover country, flyover states, and Flyoverland are American phrases describing the parts of the United States between the East and the West Coasts. The terms, which are often used pejoratively, refer to the interior regions of the country passed over during transcontinental flights, particularly flights between the nation's two most populous urban agglomerations, the Northeastern Megalopolis and Southern California. "Flyover country" thus refers to the part of the country that some Americans only view by air and never actually see in person at ground level.
