What this guide covers
The big picture in a minute
O'Hare has four passenger terminals - 1, 2, 3, and 5 (there's no Terminal 4). Terminals 1, 2, and 3 sit together in the main core and are connected, while Terminal 5 - the international terminal - is a short ride away. Inside each, the layout is consistent: an upper level for departures and check-in and a lower level for arrivals and baggage claim. Our Chicago O'Hare limo chauffeurs pick up at every one of them.
Each terminal branches into lettered concourses (your gate will be something like "C12" or "K9"), and a free train called the ATS ties everything together, including the remote parking and rental-car hub. Once you know your terminal and concourse, getting around is genuinely simple - and the maps above show every detail.
Flying in and want to skip the navigation entirely? We meet you at the terminal door or the arrivals curb - see the terminal pickup guide and full airport guide.
The ATS train ties it together
The Airport Transit System (ATS) is O'Hare's free, automated train, and it's the key to moving around. It runs around the clock and connects all four terminals with the Multi-Modal Facility - the hub for economy parking, rental cars, and the Metra commuter station.
- 1It's free and frequent. No fare, trains every few minutes, 24/7 - just follow the "ATS / Train to Terminals" signs.
- 2Links 1, 2, 3, and 5. Hop between any terminals on one loop - essential when your arrival and connection are in different terminals.
- 3Reaches the Multi-Modal Facility. The same train serves economy parking, the rental-car center, and the Metra North Central Service to the suburbs.
- 4Allow a little time. It's quick, but a terminal change means a walk to the platform plus the ride - build in a few extra minutes, especially with a tight connection.
Connecting from an international arrival at Terminal 5 to a domestic flight? You'll typically re-check bags, take the ATS to your departure terminal, and clear security again. The airport guide walks through it.
Concourses at each terminal
A quick reference to who flies where and how each terminal is organized - then open the matching map for the full detail. Airline assignments can change, so confirm on your boarding pass. For every airline, see our full list of O'Hare airlines by terminal.

Terminal 1
United's home base, with Lufthansa and ANA. Its two concourses are joined by the landmark lighted underground walkway between B and C - one of O'Hare's most recognizable spaces.
Open Terminal 1 mapTerminal 2
United Express, Air Canada, and JetBlue, among others. Compact and central in the core, with quick access to Terminals 1 and 3 and the ATS.
Open Terminal 2 mapTerminal 3
American's hub, plus Alaska and a cluster of international carriers - British Airways, Aer Lingus, Iberia, and Japan Airlines. The largest spread of concourses, so check your gate letter.
Open Terminal 3 mapTerminal 5
The international gateway, home to Delta, Frontier, and most overseas arrivals, with U.S. Customs here. A short ATS ride from the core terminals.

Beyond the terminals themselves, here's how the rest of O'Hare's ground side fits together - and where you'll find it on the full airport map.
ATS train
The automated people-mover linking all terminals and the Multi-Modal Facility. Your go-to for any terminal change or to reach economy parking and rental cars.
Connects T1 | T2 | T3 | T5 | MMF
Multi-Modal Facility
The off-terminal hub for economy parking, every rental-car brand, and the Metra North Central Service station - all reached by the ATS in a few minutes.
Has Economy parking | rental cars | Metra
Parking garages
The terminal garage is closest and priciest; economy lots at the MMF cost less but add a train ride. Compare the real cost in our parking vs. car service guide.
Tip Or skip parking entirely
Cell Phone Lot
At 560 N. Bessie Coleman Dr., this free lot is where your chauffeur stages until you're at the curb - no circling, no early-arrival fees.
For Smooth pickups
Trains to the city
The CTA Blue Line station sits beneath the core terminals and runs to downtown - handy, but slow with luggage and not ideal pre-dawn. Door-to-door is easier.
Runs O'Hare - the Loop
Ground transportation
Taxis, shuttles, rideshare zones, and pre-arranged cars all operate from the arrivals level. We meet you at the terminal door or the arrivals curb - not the rideshare deck.
Meet us Lower arrivals level
The easiest exit: skip the maze
Maps are great for finding your gate - but the simplest way out of O'Hare is to have a chauffeur waiting where you land. No tracking down a parking shuttle, no rideshare deck, no train with your bags.
- 1We meet you on arrivals. Baggage claim with a name sign, or the lower-level curb - see the pickup guide.
- 2Flat rate, flight-tracked. One fixed price with tolls included, timed to your real landing - see flight tracking.
- 3Straight to your door. Downtown, a hotel, or any suburb - check times and rates on our service-area map.
Find your way faster
A few small things that make a big airport feel small.
- Know your terminal and concourse. Your boarding pass shows both - the gate letter (B, C, E, F, G, H, K, L, M) tells you which terminal.
- Save the maps to your phone. Open the PDFs above before you fly so you have them offline in the terminal.
- Arrivals are downstairs. When you land, head to the lower level for baggage claim and your ride.
- Follow the ATS signs for any terminal change, parking, or rental cars - it's free and frequent.
- Give extra time for terminal changes. A walk plus a train ride adds up, especially with a tight connection or customs.
- Let us handle the exit. Share your flight and we'll meet you where you land - no map required.
