Airports in Illinois provide a network of air transportation facilities across Chicago, Peoria, Springfield, Rockford, Quad Cities and downstate communities, serving transportation infrastructure needs for passengers, cargo, business users and military operations. The state's airports are linked to national hubs such as Hartsfield–Jackson and Los Angeles International via carriers including American Airlines, United Airlines, Delta Air Lines, Southwest Airlines and cargo carriers like FedEx Express and UPS Airlines. Illinois airports feature roles in aviation history tied to figures and organizations such as Charles Lindbergh, Amelia Earhart, Wright brothers legacy institutions and the National Air and Space Museum network.

Overview

Illinois hosts a mix of large hub, medium, and small airports governed by entities like the Chicago Department of Aviation, Greater Peoria Airport Authority, airport authorities analogues, and municipal airport commissions in places such as Naperville and Bloomington. Key historic developments include the evolution of Midway after World War II air traffic shifts, the expansion of O'Hare International Airport during the Jet Age, and the role of airports in regional events such as World's Columbian Exposition legacy transport planning. Regulatory and funding influences stem from agencies like the Federal Aviation Administration and legislation comparable to the Airport and Airway Development Act era investments.

Illinois's primary major airports include O'Hare International Airport, a global hub for United Airlines and American Airlines operations; Chicago Midway International Airport, noted for Southwest Airlines service; and regional commercial centers such as Peoria International, Quad City International Airport, Bloomington–Normal, and connection via St. Louis influences for downstate travelers. Other significant commercial fields include Rockford International Airport, which hosts cargo operators and low-cost carriers, and Greater Chicago's Suburban Airports serving scheduled commuter links to hubs like Hartsfield–Jackson Atlanta International Airport and John F. Kennedy International.

A dense network of general aviation airports supports corporate aviation and flight training across Illinois: notable fields include DuPage Airport in West Chicago, DuPage County for business aviation; Chicago Executive Airport in Wheeling; Aurora Municipal Airport; Schaumburg Regional Airport; and community airports in Carbondale, Champaign–Urbana, Decatur, Kankakee and Moline. Flight training centers and maintenance facilities link to institutions such as University of Illinois Urbana–Champaign, Southern Illinois University, Purdue-area collaborations, and aeronautical businesses including GE Aviation and Rolls-Royce plc service centers. Community airports host events connected to organizations like the Experimental Aircraft Association and Civil Air Patrol activities.

Illinois contains military and joint-use airfields including Scott Air Force Base, a critical node for USTRANSCOM and Air Mobility Command; Weapons Systems Evaluation Program-linked facilities; and joint-use fields such as Greater Peoria Regional Airport with military installations nearby. Historic military airfields—formerly tied to World War II training such as fields in Champaign County, Rock Island Arsenal logistics, and the legacy of Naval Air Station Glenview—influence current site reuse, redevelopment projects with local authorities like Illinois Department of Transportation aeronautics divisions, and partnerships with federal entities such as Defense Logistics Agency.

Infrastructure across Illinois airports includes multi-runway complexes like O'Hare International Airport with parallel runways, instrument landing systems certified to FAA Part 139 standards, air traffic control towers operated under FAA oversight, cargo terminals used by FedEx Express and UPS Airlines, fixed-base operators affiliated with General Aviation Manufacturers Association members, and passenger terminals featuring amenities influenced by designs seen at John F. Kennedy International Airport and San Francisco International Airport. Ground access integrates with Interstate 90, Interstate 88, Interstate 55, Metra commuter rail links, Amtrak service at intermodal terminals like Chicago Union Station, and parking/people-mover systems modeled on projects in Hartsfield–Jackson Atlanta International Airport.

Passenger volumes at Illinois hubs—especially O'Hare International Airport and Chicago Midway International Airport—drive regional traffic statistics tracked by the Bureau of Transportation Statistics and influence economic analyses used by Illinois State Toll Highway Authority planners and metropolitan planning organizations like the Chicago Metropolitan Agency for Planning. Cargo throughput at Rockford International Airport and O'Hare supports logistics sectors tied to Amazon (company), Caterpillar Inc., Boeing Commercial Airplanes supply chains and resurgent manufacturing clusters in the Rust Belt transition. Economic impact studies conducted with universities such as Northwestern University and University of Illinois Urbana–Champaign quantify jobs, output, and tax revenue attributable to airports and inform capital projects financed through Airport Improvement Program grants and municipal bond issues overseen by local airport authorities.
