Chicago O'Hare International Airport Terminal Map (2025-2024)

Wayfinding matters here. Chicago O’Hare International Airport (ORD) has four active passenger terminals—1, 2, 3, and 5—which are linked by the free Airport Transit System (ATS) train. That’s because O’Hare spreads its airlines across alliances and decades of design, so walking routes and signage can vary.

The Airport Transit System (ATS) offers the quickest link between all terminals, running on elevated tracks above the parking complex. It connects Terminals 1–3 with Terminal 5 in minutes, operating continuously. Walking is possible between Terminals 1, 2, and 3 via enclosed corridors, while Terminal 5 always requires the train. Look for the blue “ATS” icons on concourse signs.

United and its partners use Terminal 1; Delta and SkyTeam carriers operate from Terminal 2; American and oneworld airlines run from Terminal 3; most international flights, including all non-precleared arrivals, use Terminal 5. Charter and seasonal carriers may shift, so always confirm in your booking or airline app before heading to O’Hare.

Daily and Hourly Parking are located closest to Terminals 1–3 within the Main Garage, with clear level markings by terminal color codes. Economy Lots G and H connect to all terminals via the ATS. For Terminal 5, use the dedicated garage or nearby surface lot across Bessie Coleman Drive. A forecourt drop-off charge applies at some areas—check signs on approach.

Plan roughly 5–10 minutes to walk between Terminals 1, 2, and 3 through secure corridors. The route from these to Terminal 5 via ATS takes about 10–15 minutes including transfer waits. Some concourses, such as 1C or 3L, have long walking paths, so allow extra time during peak departures. Overhead wayfinding signs clearly mark directions by terminal number.

Food options cluster near the central halls of Terminals 1 and 3, with local Chicago favorites beside national chains. United and American both operate large lounges near their concourses, while Terminal 5 hosts several premium spaces like the British Airways and Delta Sky Clubs. Most lounges offer access by status, ticket class, or paid entry.

O’Hare’s CTA Blue Line station sits beside the Main Parking Garage, linking all terminals via pedestrian tunnels. The ATS connects that station to Terminal 5 and Economy Parking. Metra’s North Central Service also stops nearby at O’Hare Transfer. Taxis, rideshares, and regional buses load at the lower-level curbs, so follow “Ground Transport” signs on Arrivals Level 1.
