O'Hare Airport Terminals (ORD)
Image
Navigating O’Hare Airport is a tale of contrasts. As one of the busiest hubs in the world, it can be impressively efficient—or a confusing maze that tests your patience. This guide provides a realistic perspective, based on thousands of traveler reviews, so you know what to expect at each terminal, how to move efficiently, and how to avoid the most common pitfalls.
Quick answers for your visit to O’Hare
- Which is the international terminal? Terminal 5 handles the vast majority of international arrivals and departures. Keep in mind it has the longest immigration wait times, which can make connections tight.
- How do I get between terminals? Use the Airport Transit System (ATS), a free train running 24/7 connecting terminals 1, 2, 3, and 5 to the Multi‑Modal Facility (car rental & parking). Warning: Night service is much less frequent, resulting in longer waits.
- Which terminal does United use? And American? United Airlines is based in Terminal 1 (Concourses B & C). American Airlines flies mostly from Terminal 3 (Concourses G, H, K, L).
- Is there a lot of walking? Yes, quite a bit. O’Hare is known for its long distances and limited moving walkways. Transferring between concourses can take 15–25 minutes. Wear comfortable shoes and allow extra time.
- Which terminal has the best food? Though terminals 3 and 5 offer popular options like Tortas Frontera, many restaurants close early (8–10 PM). If you have a late flight or delays, food options become very limited.
The airport comprises four terminals. A free train (ATS) connects all terminals and the Multi‑Modal Facility (MMF – car rentals & parking), Kiss ’n’ Fly lots and bus station. A free shuttle bus (TTB) links Terminal 5’s secure area with terminals 1 and 3. Terminals 1, 2 and 3 share a secure zone connected by pedestrian bridges. MORE INFO

The Real Experience: Highlights and Pitfalls of O’Hare’s Terminals
Beyond official terminal maps, real travel experiences shape how you perceive O’Hare. Based on recent reviews, here’s an honest summary of what to expect.
Actual Walking Distances & Signage
User insights: A top complaint is the need to walk long distances. The scarcity of moving walkways frustrates many, especially travelers with reduced mobility or families. Gate-to-gate transfers can be substantial. Signage, especially to the ATS or rideshare pickup zones, is often described as confusing or insufficient.
Common Operational Challenges: Delays, Gate Changes & Baggage
User insights: O’Hare faces three recurring bottlenecks:
- Runway delays: It’s common to land and wait on the tarmac for 30–90 minutes until a gate is available.
- Last-minute gate changes: Frequent. Always check your airline app and terminal screens.
- Baggage issues: Reports include delays, lost items, or carousel changes—especially on international flights.
Staff Experience: A Mixed Bag
User insights: Interactions can be hit or miss. Some travelers report unhelpful or rude encounters with airline agents and TSA. But many also praise standout employees—like TSA Officer Norris or United supervisor Trevor—for their professionalism and friendliness. Your experience can vary drastically.
Infrastructure & Cleanliness: Mixed Reviews
User insights: The term “dated” frequently appears. While some areas are modern, many parts feel old. Cleanliness is uneven—restrooms in Terminal 5 often receive harsh criticism. Faulty power outlets and lack of seating in waiting areas are also common complaints.
Terminal 1 (Concourses B, C)
This terminal has two concourses: B (gates B1–B24) and C (C1–C31), totaling 52 gates. It mainly hosts United Airlines (domestic & international), Lufthansa, and All Nippon Airways.
Concourse B houses ticket counters, baggage claim, and security. Concourse C is a satellite terminal on both sides, linked via a neon-lit underground pedestrian tunnel.
User insights:
As United’s main hub, experience here depends heavily on the airline. The neon tunnel between B and C is visually impressive, but the walk to Concourse C is substantial. Crowding during peak times, limited seating, and unreliable outlets near gates are often reported.
Upper Level: Direct access to curbs, departures, and the ATS.
Lower Level: Baggage claim and ground transport: charter buses, taxis, and limos. Bus center on level 1.

Terminal 2 (Concourses E, F)
This terminal operates many domestic flights within Concourses E (gates E1–E17) and F (F1–F28), totaling 41 gates.
User insights:
Terminal 2 is mainly known as the central rideshare pickup zone (Uber/Lyft), which makes it a high-traffic area. You’ll need to take the ATS or walk via outdoor paths from other terminals—which can be very inconvenient in bad weather. Travelers describe it as narrow and outdated, with a circular design that can be disorienting. Food lines often block walkways.
Lower Level: Baggage claim and ground transportation: taxis, charter buses, and limos. Bus & shuttle center on level 1, with access to downtown trains. The Hilton Hotel is located near the lower level and parking garage.
Upper Level: Departures and check-in counters leading to the gates.

This terminal includes four concourses with 80 gates: G (G1A–G21), H (H1–H18), K (K1–K20), and L (L1A–L12). It handles domestic flights and international departures for American Airlines.
User insights:
As the hub for American Airlines, Terminal 3 is extensive and its layout can be complex. A frequent complaint is the long walking distance between concourses, especially from H/K to L. However, it offers good service options and the Admirals Club is well-reviewed. Like other terminals, it suffers from congested boarding areas and a lack of seating.
Lower Level: Arrival and baggage claim area, with access to various ground transportation options.

Terminal 5 (Concourse M)
Terminal 5 consists of a single concourse (M), with 35 gates (M1–M40), and handles nearly all international arrivals and departures.
User insights:
This terminal receives the harshest feedback from international travelers. Most mentioned issues include:
- Long immigration lines: A top reason why many miss connecting flights. Waits of over two hours are common.
- Long walking distances: Expect a lengthy trek from your gate to the exit. Past gate M25, shops and dining options become scarce.
- Cleanliness and organization: Often cited as the dirtiest and most chaotic terminal, especially the restrooms.
- Positive notes: The Delta Sky Club here is one of the best-rated lounges at O’Hare. Terminal 5 also hosts some domestic carriers like Southwest and Frontier, so always double-check your terminal before flying.
Lower Level: Arrival area with baggage claim (carousels 10 and 11) and the ATS station linking Terminal 5 to other terminals and ground transport options.
Upper Level: Ticketing and check-in for departures.
