O'Hare International Airport ORDKORD

Chicago O'Hare (ORD) is one of the key connecting airports in the U.S. Midwest and a major hub for both United Airlines / Star Alliance and American Airlines / oneworld. It handles a dense mix of domestic trunk routes, regional feeder flights and long-haul international service, so it works well for network connections but rewards travelers who know the terminal layout. Terminals 1, 2 and 3 are the core domestic complex and are connected on the secure side; Terminal 5 is the main international terminal and also hosts several non-hub carriers. For downtown Chicago, the CTA Blue Line is usually the most predictable choice: it runs 24 hours from the airport to the Loop, with a typical ride around 40-50 minutes before walking or local transit at the city end. The main caution for transit passengers is Terminal 5: there is an airside Terminal Transfer Bus during limited daytime/evening hours for eligible connecting passengers, but outside that window you may need the ATS people mover and another TSA screening.
