It is bordered by 55th Street, Cicero Avenue (terminal entrance), 63rd Street, and Central Avenue. The airport's northern half is within the Garfield Ridge community area, and the southern half is within the Clearing community area. The airport is managed by the Chicago Airport System, which also oversees operations at O'Hare International Airport and Gary/Chicago International Airport. The airport is named after the Battle of Midway during World War II.
