Gary/Chicago International Airport (GYY) is a public airport located in Gary, Indiana, approximately 25 miles southeast of downtown Chicago. It serves as a reliever airport for the busy Chicago metropolitan area and handles a mix of general aviation, charter, and limited commercial operations. The airport sits on roughly 1,700 acres and features two runways capable of accommodating a variety of aircraft types. Historically, it has attracted interest as an underutilized asset that could absorb overflow traffic from O'Hare and Midway airports. Gary has pursued expansion and redevelopment efforts over the years to attract more commercial carriers, though scheduled passenger service has been intermittent. The facility is owned and operated by the City of Gary and continues to serve cargo, freight, and general aviation customers.
