Chicago O’Hare International Airport (ORD) was the busiest U.S. airport in 2018 in terms of aircraft movements, serving over 900,000 flights. It’s a major airport for connections all over the U.S., operating as the main hub for United Airlines and the third-largest hub for American Airlines.

Flight connections are easy between the 3 domestic terminals, all connected by airside pedestrian walkways. However, Terminal 5 is a bit more of a journey for international flight connections.

That’s set to change in the future with a huge expansion project planned to commence in 2021. This will redevelop Terminal 2 to accommodate both domestic and international flights under the same roof.

In the meantime, here’s what you need to know to get around O’Hare.

ORD Airport Terminals

The road system that runs inside ORD is a hexagonal shape, with Terminals 1, 2, and 3 situated along the outside of the bottom 3 sides, and the parking lots, Multi Modal Facility (car rental), and I-190 located in the top half.

Terminals 1-3 are referred to as the domestic terminals, and these 3 terminals are connected to each each via pedestrian walkways.

Terminal 5, the last terminal to be built, is located a short distance from the other terminals, connected by shuttle services and the Airport Transit System (ATS.) Although it is referred to as the international terminal, some international flights do depart from other terminals — but they only arrive into Terminal 5.

Terminal 1

Terminal 1 (T1) consists of concourses B and C, with concourse B attached to the main terminal, and concourse C as a satellite terminal, connected by an underground pedestrian walkway.

Overall, the terminal has 54 gates, numbered B1-B12, B14, B16, B16A, B17, B17A, and B18-B24 in concourse B, and C1-C10, C10A, C11, C15, C16, C16A, C17, C18, C18A, C19-C23, and C25-C31 in concourse C.

Both concourses have shops and restaurants and a United Club Lounge. Concourse C also has a United Polaris Lounge, as T1 is the primary terminal for United Airlines for both domestic and international flights.

Terminal 2

Terminal 2 has a total of 41 gates across 2 concourses. Concourse E has gates numbered E1-E17, and concourse F has gates numbered F1, F3-F7, F9-F12, F14-F17, and F19-F28.

The lower numbered gates are situated in the main terminal, with E gates on the right and F gates on the left, until the terminal forks into the individual concourses.

There are shops and restaurants across both concourses, a Delta Sky Club Lounge in concourse E, and a United Club Lounge in concourse F.

Terminal 3

Terminal 3 is a large terminal, consisting of 4 concourses and 76 gates numbered as follows:

• Concourse G: G1A, G1B, G2A, G2B, G3-G5, G6B, G7-G14, G14A, G16-G19, G19A, G20, and G21
• Concourse H: H1-H6, H8-H10, H11A, H11B, H12, and H14-H18
• Concourse K: K1-K6, K8-K10, K12, K13, K15, K16, and K18-K20
• Concourse L: L1, L1B, L2A, L2C, L3-L5, L6A, L6B, L7-L9, L10A, L10B, L10C, L11, L11A, and L11B

If passing through the central security checkpoints, concourse G is to the far right, concourses H and K are down the main central walkway, with concourse H to the right where it forks and concourse K to the left. Concourse L is to the far left of the terminal.

Concourse G has an Admirals Club Lounge, and concourse H has an American Airlines Flagship Lounge.

Terminal 5

Terminal 5 is ORD’s main international terminal, as it’s where the most international airline ticket desks are based. T5 also serves some domestic flights, and the other terminals serve some international flights.

In T5, flights depart from concourse M, where there are 21 gates numbered M1-M21. Passing through the security checkpoint, gates M12-M21 are to the left, M8-M11 are straight ahead, and gates M1-M7 are to the right.

Inter-Terminal Transport

Connecting between Terminals 1-3 and Terminal 5 is usually straightforward via the Airport Transit System (ATS) that runs between terminals. However, the ATS is currently closed for modernization, and replacement transfer buses are in place for passengers.

The ATS is due to re-open in early 2020 (no date disclosed) and will have double the passenger capacity. The train service is also being extende3d to connect passengers to the new Multi-Modal Facility for the car rental center and off-site parking.

Airside Transport Post-Security

Terminal Transfer Bus (TTB)

The terminal transfer bus transports domestic arrival passengers between Terminals 1-3 and Terminal 5 for connecting flights, without the need to re-clear security again on arrival at T5.

This service is for passengers who are not required to collect their luggage in between connections, and it’s not available for international passengers arriving into T5 with connections in Terminals 1-3.

Buses operate daily from 11 a.m. to 9 p.m. and depart from the following locations in Terminal 3:

• Gate G17
• Gate K20
• Gate L24

Walking

Terminals 1-3 are connected by airside walkways, which are useful for passengers arriving on a domestic flight and connecting to another domestic flight.

To walk from Terminal 1 to Terminal 2, the walkway is located on the departures level, opposite Gates B5 and B6. The walkway arrives near gate E1 in Terminal 2.

To reach Terminal 3 from Terminal 2, the walkway is located near Gate F1 and arrives into the Rotunda of Terminal 3.

Walking time will depend entirely on which concourse and gate you’re walking to and from. The furthest points (Terminal 1, concourse C to Terminal 3, concourse L) are just over a mile apart from each other, so at an average speed, the maximum walking time would be around 20 minutes.

Landside Transport Pre-Security

Airport Transit System (ATS)

The ATS is a light rail service that stops at all terminals. It’s located outside of the secure area, so you do need to re-clear security again at your connecting terminal.

Each terminal has an ATS station located landside and is well signposted with “ATS” signs. Trains depart frequently and run in both directions, so you can choose the route that will get you to your connecting terminal quickest.

ORD Airport Hotels – Sorted by Distance from ORD

Top 3 Hotel Stays Using Points

The Hyatt Regency O’Hare is both the largest hotel outside the city and the largest convention center near the airport. The hotel offers great dining, a free airport shuttle, access to the “L” train, and Regency club access to Globalist members or those who purchase an eligible room. This hotel is a real steal for World of Hyatt members that can book this hotel at just 8,000 Hyatt points per night.

The Westin O’Hare provides close proximity to not only O’Hare International airport, but also the Allstate Arena and Fashion Outlets of Chicago. Travelers receive a complimentary shuttle service, access to the “L” train, a fitness center, indoor pool, and Starbucks coffee. Marriott Bonvoy rewards members can book a room for just 20,000 points on off-peak nights, 25,000 points on standard nights, and 30,000 points on peak nights.

Guests at the DoubleTree by Hilton Chicago O’Hare can enjoy the property’s fitness center, pool, and business center, along with popular dining options like Gibsons Steakhouse and BC Bistro. DoubleTree is a member of the Hilton Hotels portfolio, so Hilton Honors members can book a room for 40,000 Hilton points per night, and guests with Hilton Gold status or higher receiver a complimentary breakfast each morning.

Hot Tip: Looking to have hotel status but don’t meet the stay requirements? There are lots of credit cards that award you complimentary hotel status simply for having the card. 

O’Hare 21 Expansion Plan

Chicago recently announced the winning architectural firm for the O’Hare 21 expansion plan for a new Global Terminal. With an estimated completion of 2028, you’ll be waiting a while. But the $8.5 billion expansion project will replace the existing T2 with a modernized terminal and 25 additional gates.

The winning design by lead architects Studio Gang aims to bring the outdoors in, with lots of trees, sunlight, and open space. T2’s additional capacity will enable both domestic and international flights to depart from the new terminal.

Final Thoughts

Getting around ORD hasn’t been as seamless as usual lately with the closure of the Airport Transit System for renovations.

When the ATS re-opens in the fall, train service will be extended to the Multi-Modal Facility, meaning passengers can travel between the terminals, car rental center, economy car parking lots, and Metra train station with ease.

And it’s not just the new Global Terminal that’s currently in the pipeline — Terminal 5 is due to receive significant improvements over the next few years. 2021 will see its capacity increased by 25% with an extra 350,000 square feet, and 2022 will unleash roadway enhancements and expanded curbside pick-up and drop-off areas.
