There are many airports in Illinois. However, not all Illinois airports have regularly scheduled flights. We do not list the smallest airports, since there is no way to provide you flights from those airports.
Illinois (pronounced "ill-i-NOY") is the 21st U.S. state and is located in the Midwest region of the United States of America. The state is known for its large and diverse population, its balance of rural areas, small industrial cities, vast suburbs and great metropolis, its highly diverse economic base, and its central location that has made it a transportation hub for 150 years. It is this mixture of factory and farm, of urban and rural that makes Illinois a microcosm of the nation.
The state is named for the Illinois River which was named by French explorers after the indigenous Illiniwek people, a consortium of Algonquian tribes that thrived in the area. The word Illiniwek means "tribe of superior men."
The northeastern border of Illinois is Lake Michigan. Its eastern border with Indiana is basically all of the land west of the Wabash River. Its western border with Missouri and Iowa is the Mississippi River. Its southern border with Kentucky is the Ohio River.
Though Illinois lies entirely in the Interior Plains, it has three major geographical divisions. The first is Chicagoland, including the city of Chicago, its suburbs, and the adjoining exurban area into which the metropolis is expanding. This region includes a few counties in Indiana and Wisconsin and stretches across much of northern Illinois toward the Iowa border, generally along Interstates 80 and 90. This region is cosmopolitan, densely populated, industrialized.
Southward and westward, the second major division is central Illinois, an area of mostly flat prairie. The western section forms the distinctive western bulge of state. Known as the Land of Lincoln or the Heart of Illinois, it is characterized by small towns and mid-sized cities. Agriculture, particularly corn and soybeans, as well as educational institutions and manufacturing centers, figures prominently.
The third division is southern Illinois, which can be distinguished from the other two by its warmer climate, different mix of crops (including some cotton farming in the past), more rugged topography, as well as small-scale oil deposits and coal mining. ( )
