How long does it take to go from Terminal 1 to Terminal 2 in Chicago?

Most tutorials teach you how to navigate OHare, but theres one critical mistake that causes travelers to miss their connections - Ill explain it in the transportation section below.

It takes about 10 to 15 minutes to walk between Terminal 1 and Terminal 2 at Chicago OHare International Airport (ORD). ^[1] Because these terminals are physically connected and share a secure zone, you do not need to exit the airport or pass through security again.

So, how exactly do you get there? Simply put, you just follow the overhead signage and walk. The entire path is indoors, climate-controlled, and relatively flat. You dont have to worry about catching a bus or braving the Chicago winter.

Navigating the Concourses

Terminal 1 houses 52 gates across Concourses B and C. Terminal 2 contains 41 gates between Concourses E and F.^[3] The walk usually takes you from the middle of Concourse B, past the security checkpoints, right into the beginning of Concourse E or F.

Lets be honest - navigating an unfamiliar airport is stressful. My first time connecting through ORD, I panicked seeing my next flight was in a different terminal. I thought Id have to ride a shuttle, re-clear TSA, and sprint. Turns out, its just a long hallway.

Walking between these terminals is very simple.

The transition is so seamless that many passengers dont even realize theyve crossed into a different terminal until they see the letter change on the gate signs. From B to E, the walk is straightforward.

The Airport Transit System (ATS)

Here is that critical mistake I mentioned earlier: leaving the secure area to take the train. Many travelers see signs for the ATS and assume its the fastest way between any two terminals. If you are connecting between T1 and T2, taking the ATS forces you to exit the secure zone and go through TSA screening all over again. Huge mistake.

However, if you havent gone through security yet, or if you need to reach Terminal 5, the train is your best option. The Airport Transit System (ATS) trains run every 3-5 minutes during peak hours. ^[4]

The modern ATS trains reach speeds up to 50 mph. Each three-car ATS train can transport 147 passengers. Taking the ATS covers the distance from Terminal 1 to the Multi-Modal Facility in about 10 minutes. ^[7]

Conventional wisdom says to always use the airport trains to save time and energy. But based on my experience, walking airside is almost always faster for domestic connections - you never risk a 30-minute TSA line ruining your layover.

The Famous Neon Tunnel

If you are starting your walk from Concourse C in Terminal 1, you will first need to pass through the underground pedestrian walkway. This isnt just any tunnel. It features The Skys the Limit - a mesmerizing neon light installation paired with a continuous synthesizer soundtrack.

It is pretty much an attraction in itself.

You step onto the moving walkway, look up at the shifting colors, and for a minute, you forget youre dragging a suitcase. (23 words) The music hums. (3 words) But dont get too distracted - you still have a connection to catch. (13 words) Keep moving toward Concourse B, take a right, and follow the signs to Terminal 2. (15 words)

Airlines and Amenities

Terminal 1 is primarily the domain of United Airlines. If you are flying domestically with United, this is usually your hub. Terminal 2 handles Air Canada, Alaska Airlines, JetBlue, and some regional United Express flights.

If you have some time to kill, both terminals offer excellent food options. You can grab a quick sandwich at Berghoff Cafe in Terminal 1, or enjoy a sit-down meal at Summer House Santa Monica in Terminal 2.

Walking vs. Airport Transit System (ATS)

Depending on where you are in the airport, you have two main ways to get from Terminal 1 to Terminal 2.

⭐ Walking (Airside)

1. You remain inside the secure zone and do not need to clear TSA again
2. Takes about 10 to 15 minutes depending on your gate location and walking pace
3. Connecting passengers with domestic layovers who are already past security

ATS Train (Landside)

1. Located outside the secure zone, requiring you to go through TSA screening upon re-entry
2. Train ride is fast, but adding security lines makes it much slower overall
3. Passengers who just arrived at the airport and haven't gone through security yet

The Chicago Connection Dash

David, a 45-year-old sales manager, landed at Concourse C (Terminal 1) on a delayed United flight with only 35 minutes until his connection to Seattle departed from Concourse F (Terminal 2). He was exhausted, his feet ached, and he assumed he had to take the airport train.

He exited the secure area, followed signs for the ATS, and arrived at the train platform. When he realized the train was landside, he panicked - he'd have to clear TSA again. The line was massive.

He quickly asked an airport employee, who redirected him back to the main terminal entrance. He had to beg the TSA agents to let him use the priority lane. He barely made it through.

David sprinted to Concourse F and caught his flight as the doors were closing. He learned the hard way that walking indoors airside is always the safer bet for domestic connections, saving the massive headache of re-clearing security.
