Airports & Getting Around Illinois
Illinois's air-travel access is genuinely dominated by Chicago's two major airports -- O'Hare International, one of the busiest airports in the world by traffic, and Midway International -- with far more limited regional airport access across downstate Illinois.

Learn moreO'Hare International Airport is a real, major global aviation hub
O'Hare International Airport is consistently one of the busiest airports in the world by total traffic and a genuine hub for both United Airlines and American Airlines, driving substantial logistics, hospitality, and aviation-sector employment across Chicago's northwest suburbs -- a real, major economic anchor distinct from Chicago's downtown Loop economy, and a real global-connectivity advantage for anyone relocating to the Chicago area.
Midway International Airport offers a real, distinct second option
Midway International Airport, on Chicago's southwest side, offers a real, distinct alternative to O'Hare -- generally serving more domestic, lower-cost-carrier routes and closer to the city's South Side and southwest suburbs, a genuinely useful option depending on your specific Chicagoland destination.
Downstate Illinois relies on regional airports and Chicago's own hub for most air travel
Outside Chicagoland, Illinois's air-travel access is genuinely more limited -- downstate residents in the college-town corridor, Rockford, the Metro East (which has real, practical access to St. Louis Lambert International Airport given the region's genuine St. Louis orientation), and Springfield typically rely on smaller regional airports with limited route networks, or drive to Chicago's O'Hare or Midway for broader connectivity. Confirm your specific target region's nearest airport and route network directly.
The Quad Cities share air-travel access across the Iowa border
The Illinois side of the Quad Cities (Moline) shares practical air-travel access with the binational metro's own regional airport, consistent with the region's broader shared-metro identity with Davenport, Iowa.
Key takeaways
- O'Hare International Airport is a real, major global aviation hub -- one of the busiest airports in the world, and a genuine hub for United and American Airlines.
- Midway International Airport offers a real, distinct second Chicago airport option, generally serving more domestic and lower-cost-carrier routes.
- Downstate Illinois relies on smaller regional airports (or the Metro East's practical access to St. Louis Lambert) for most air travel, with more limited route networks than Chicago's hubs.
- Confirm your specific target region's nearest airport and route network directly rather than assuming one statewide Illinois air-travel picture.
