Navigating O’Hare: Your Ultimate Guide to Inter-Terminal Travel (Domestic)
Chicago O’Hare International Airport (ORD) is one of the busiest airports in the world, a major hub connecting travelers across the globe. While its international connections are significant, its domestic terminal network is equally vital. Navigating between Terminals 1, 2, 3, and even reaching Terminal 5 (for possible connecting international flights necessitating a transfer within security) can seem daunting, especially for first-timers or those with tight layovers. This comprehensive guide provides detailed, step-by-step instructions, insider tips, and helpful advice to ensure a smooth and stress-free transfer experience within O’Hare’s domestic terminals.
## Understanding O’Hare’s Domestic Terminals
Before delving into the specifics of inter-terminal travel, it’s crucial to understand the layout of O’Hare’s domestic terminals:
* **Terminal 1 (B & C Concourses):** Primarily serves United Airlines and its United Express partners. This terminal is characterized by its long concourses and numerous gates.
* **Terminal 2 (E & F Concourses):** Home to Air Canada, Delta, and some United Express flights. It’s generally smaller and less congested than Terminal 1.
* **Terminal 3 (G, H, K, & L Concourses):** Houses American Airlines and some other airlines. It’s a large terminal with a wide range of amenities and services. The ‘L’ concourse is particularly long and can involve significant walking.
While Terminal 5 is primarily for international flights, some domestic airlines might operate out of it on occasion. In such a case, transferring between a domestic terminal (1, 2, or 3) and Terminal 5 becomes relevant, and this guide will cover that scenario as well, especially focusing on maintaining security.
## Methods for Inter-Terminal Travel at O’Hare (Domestic)
There are three primary methods for traveling between the domestic terminals at O’Hare:
1. **The Airport Transit System (ATS) – ‘People Mover’:** This is a free, automated train system that connects all four terminals (1, 2, 3, and 5) as well as the remote parking lots and the Multi-Modal Facility (MMF), which houses rental car companies. It’s generally the fastest and most convenient option, *especially if you need to go to Terminal 5*.
2. **Walking (Within Security in some cases):** It’s possible to walk between Terminals 1, 2, and 3 *without* exiting security. This option is ideal for those who enjoy stretching their legs, have a longer layover, or prefer to avoid potential delays with the ATS. However, it’s important to note that the walking distances can be significant, particularly between the far ends of Terminals 1 and 3. Walking to Terminal 5 requires exiting security and using the ATS.
3. **Re-clearing Security (If you exit the secured area):** If you exit security for any reason (e.g., to visit a restaurant outside security, collect checked baggage that was misrouted, or meet someone), you’ll need to re-clear security at your connecting terminal. This is generally the least desirable option due to the time it takes to go through security checkpoints, especially during peak travel times. *This is the *only* option if you want to access areas of terminals past security after exiting.*
## Step-by-Step Instructions for Each Method
### 1. Using the Airport Transit System (ATS)
The ATS is the most efficient way to travel between all terminals, especially if your connection involves Terminal 5. Here’s how to use it:
* **Follow the Signs:** Look for signs that say “ATS” or “Airport Transit System.” These signs are prominently displayed throughout each terminal and will lead you to the ATS stations.
* **Locate the ATS Station:** Each terminal has its own ATS station, usually located on the lower level (near baggage claim). In Terminals 1, 2 and 3 follow signs for “Ground Transportation” and then “ATS.” In Terminal 5, the ATS station is located above baggage claim.
* **Board the Train:** The trains run frequently (every few minutes) and are free to use. They are fully automated, so there is no driver.
* **Check the Destination:** Before boarding, double-check the electronic display on the train platform to ensure it’s heading in the direction you need to go. The display will show the upcoming stops.
* **Ride to Your Destination:** The train will make stops at each terminal (Terminal 5, Terminal 3, Terminal 2, Terminal 1). Listen for the announcements and watch for the signs to know when to exit at your desired terminal.
* **Follow Signs to Your Connecting Flight:** Once you exit the ATS station, follow the signs to your connecting flight’s concourse and gate. If you’re staying within the secure area (important if coming *from* or going *to* Terminal 5 from domestic terminals), look for signs directing you *back* into the terminal security area.
**Specific Considerations for Terminal 5:**
* **Traveling *to* Terminal 5 from a Domestic Terminal:** If you’re transferring to an international flight from Terminal 5, and you *already* have your boarding pass, you should take the ATS. When you arrive at Terminal 5, follow signs for “Departures” and proceed to your gate. If you *don’t* have a boarding pass you may need to check in at a transfer desk or with your airline at Terminal 5.
* **Traveling *from* Terminal 5 *to* a Domestic Terminal:** Upon arrival at Terminal 5, after clearing customs and immigration (if applicable), you will typically be *outside* the secure area. Follow signs for “Ground Transportation” and then “ATS.” Take the ATS to your connecting terminal (1, 2, or 3). You *will* need to re-clear security at your connecting terminal. If you are transferring to a *domestic* flight after arriving *internationally* at Terminal 5, it’s extremely important to allow ample time (at least 2-3 hours) for customs, immigration, baggage reclaim (if needed), and re-checking your bags (if needed) *before* going through security at your connecting terminal. Baggage reclaim is *always* outside security. Re-checking bags *may* be outside security depending on the airline.
### 2. Walking Between Terminals (Within Security – Terminals 1, 2, & 3 ONLY)
Walking is a viable option *only* between Terminals 1, 2, and 3, and *only if you wish to remain within the secure area*. It’s best suited for those who have sufficient layover time and prefer to get some exercise.
* **Follow the Signs:** Look for signs indicating the direction to the other terminals (e.g., “Terminal 2 ->,” “Terminal 3 ->”). These signs are usually located near the gate areas and along the main walkways.
* **Understand the Layout:** Be aware that the walking distances can be significant, especially between Terminal 1 (Concourse C) and Terminal 3 (Concourse L). Allow ample time for your walk.
* **Terminal 1 to Terminal 2:** This is a relatively short and straightforward walk. Simply follow the signs between the B and E concourses. The pathway is well-marked and easily accessible.
* **Terminal 2 to Terminal 3:** This is another relatively easy walk, connecting the F and G concourses. Again, follow the directional signs.
* **Terminal 1 to Terminal 3 (or vice versa):** This is the longest walk within the secure area. You’ll essentially be walking through Terminal 2 to get between Terminals 1 and 3. Be prepared for a considerable distance and allow plenty of time.
* **Stay Within the Secure Area:** Make sure you *do not* accidentally exit the secure area during your walk. Pay close attention to the signs and ensure you are following the correct path. Once you exit security, you will need to re-clear it at your connecting terminal.
**Pros and Cons of Walking:**
* **Pros:** No waiting for the ATS, good exercise, can be quicker if the ATS is experiencing delays, avoids potential crowds.
* **Cons:** Long walking distances, can be tiring, may not be suitable for those with mobility issues, not an option for travel to/from Terminal 5 without exiting security.
### 3. Re-clearing Security
This option is only necessary if you have exited the secure area for any reason. It’s generally the least desirable option due to the time and hassle involved.
* **Exit the Secure Area:** Follow the signs for “Baggage Claim” or “Ground Transportation” to exit the secure area of your arrival terminal.
* **Proceed to Your Connecting Terminal:** Use the ATS to reach your connecting terminal.
* **Find the Security Checkpoint:** Locate the security checkpoint for your connecting terminal. Checkpoints are typically well-marked with signs.
* **Prepare for Security:** Have your boarding pass and ID ready. Remove shoes, belts, and any items containing metal. Place liquids in a clear, quart-sized bag and remove laptops from their cases.
* **Go Through Security:** Follow the instructions of the TSA officers and cooperate with the screening process.
* **Proceed to Your Gate:** Once you have cleared security, follow the signs to your connecting flight’s concourse and gate.
**Important Considerations for Re-clearing Security:**
* **Allow Ample Time:** Security lines at O’Hare can be long, especially during peak travel times. Allow at least 1-2 hours to re-clear security, especially if you are traveling during busy periods (e.g., holidays, weekends).
* **TSA PreCheck and Global Entry:** If you have TSA PreCheck or Global Entry, you can use the expedited security lanes, which can significantly reduce your wait time.
* **Mobile Passport Control (MPC):** Use MPC app if eligible to potentially expedite your entry into the US at Terminal 5 if arriving internationally.
## General Tips for Smooth Inter-Terminal Transfers at O’Hare
* **Check Your Flight Status:** Before your flight and upon arrival, check the status of your connecting flight for any delays or gate changes. This will help you plan your transfer accordingly.
* **Download Your Airline’s App:** Many airlines offer mobile apps that provide real-time flight information, gate changes, and other helpful travel updates. They often have interactive airport maps.
* **Use Airport Maps:** O’Hare provides airport maps online and in the terminals. These maps can help you navigate the airport and locate the ATS stations, security checkpoints, and your connecting gates.
* **Ask for Help:** If you are unsure of anything, don’t hesitate to ask airport staff for assistance. Information booths are located throughout the terminals, and staff are usually happy to help.
* **Consider a Mobile App:** Apps like Flighty can provide real-time status updates and airport navigation assistance.
* **Pack Light:** Traveling with less luggage will make your transfer easier, especially if you choose to walk between terminals.
* **Wear Comfortable Shoes:** You’ll likely be doing a lot of walking, so comfortable shoes are essential.
* **Stay Hydrated:** Air travel can be dehydrating, so drink plenty of water.
* **Charge Your Devices:** Make sure your phone, tablet, or other devices are fully charged before your flight. Power outlets are available in the terminals, but they can be crowded.
* **Plan for Meal Times:** If you have a long layover, plan for meal times. O’Hare offers a wide variety of restaurants and cafes.
* **Factor in Time for Delays:** Always allow extra time for potential delays, such as security lines or ATS disruptions.
* **Know Your Airline’s Baggage Transfer Policy:** Confirm whether your baggage will be automatically transferred to your connecting flight or if you need to collect it and re-check it. This is especially important for international connections through Terminal 5.
* **For International Transfers from Terminal 5:** Be sure to inquire with your airline about procedures for connecting flights and baggage transfer to ensure a smooth transition.
## Special Considerations for Passengers with Disabilities
O’Hare is committed to providing accessible facilities and services for passengers with disabilities. Here are some things to keep in mind:
* **Wheelchair Assistance:** If you require wheelchair assistance, contact your airline in advance to arrange for it. Wheelchair assistance is available at the gate, at baggage claim, and throughout the terminals.
* **Accessible Transportation:** The ATS is fully accessible to passengers with disabilities. Elevators and ramps are available at all stations.
* **Accessible Restrooms:** Accessible restrooms are located throughout the terminals.
* **Service Animals:** Service animals are welcome at O’Hare. Be sure to have the necessary documentation for your service animal.
* **TSA Cares:** The TSA Cares helpline can provide assistance to travelers with disabilities and medical conditions. Contact them at least 72 hours before your flight.
## Common Scenarios and Solutions
* **Tight Connection:** If you have a very tight connection (less than an hour), inform the flight attendant on your arrival flight. They may be able to arrange for assistance to help you make your connecting flight. Use the ATS to save time, and don’t hesitate to ask for help.
* **Missed Connection:** If you miss your connecting flight due to a delay, contact your airline immediately. They will rebook you on the next available flight.
* **Lost Luggage:** If your luggage is lost, file a claim with your airline at the baggage claim area. Be sure to keep a copy of your baggage claim tag.
* **Gate Change:** Gate changes can happen, so monitor the monitors and listen for announcements. Confirm your new gate before heading there.
