O’Hare International Airport (ORD) is a large, hub-centric facility where many travelers need to move between terminals for connections, rechecks, or meeting points. Walking is possible between certain terminals, notably within the domestic terminals, while other moves require the Airport Transit System or buses. This guide explains the walking routes that exist, approximate times, security checkpoints you may encounter, and practical choices for each connection type. The guidance is designed to help you plan reliable O’Hare connections using only verified, evergreen details.
Which Terminals Are Connected by Walking?
At O’Hare, the most common walking routes occur in the domestic terminal complex and within the international (B Concourse) gates. The specifics depend on whether you are landside (pre-security) or airside (post-security).
Domestic Landside Walks
Between Terminal 1 (gates B and C), Terminal 2 (gates D and E), and Terminal 5 (the international/domestic hybrid building), you can walk on the lower level from the arrivals corridor and moving sidewalks. These routes connect security checkpoints and ticketing areas and typically do not require leaving the secured zone if you remain between gates. Expect 10 to 20 minutes of walking time depending on your origin and destination.
Domestic Airside Walks
On the departure level, airside walks through jet bridges are possible between some gates in the same terminal. For example, within Terminal 1, you can move between B and C concourses via connecting bridges without rechecking bags. In Terminal 2, gates D and E often allow jet bridge or covered walkway movement. Walking time between nearby domestic gates is usually 5 to 15 minutes.
International and Cross-Complex Moves
Moving between the domestic complex and Terminal 5 international gates, or between Terminal 5 and the B Concourse (gates for international and some domestic), typically requires a secure walk through Terminal 5 combined with a possible border control step if you are changing zones. From the B Concourse, you generally must use the Airport Transit System to reach other terminals, as there is no public walking route across the airside between B and the distant domestic terminals.
O’Hare Walking Route Summary at a Glance
| Route | Walk Time (approx.) | Security Checkpoint | Vehicle or Shuttle Needed |
|---|---|---|---|
| Terminal 1 ↔ Terminal 2 (domestic landside) | 10–20 minutes | May require re-screening when changing security levels | No |
| Terminal 1 B ↔ Terminal 1 C (airside jet bridge) | 5–10 minutes | Usually none within same secure area | No |
| Terminal 2 D ↔ Terminal 2 E (airside walkway) | 5–12 minutes | Usually none within same secure area | No |
| Terminal 5 ↔ B Concourse (international) | 15–30 minutes + border control | Border control or security re-screening likely | No walking across airside |
| Any domestic terminal to any other via airside across terminals | N/A | Not available; use train/bus | Yes (train or shuttle) |
Practical Tips for Walking Between Terminals
- Follow clear signage for your terminal and concourse; colors and letters help navigate the complex.
- Check your boarding pass for terminal and concourse information before leaving your gate.
- If you must leave the secure area, factor in extra time for security lines at re-entry points.
- Use moving sidewalks and elevators to reduce walking time and fatigue.
- For distant terminals or if you have tight connection times, prefer the Airport Transit System or official shuttle services over long walks.
When Walking Is Not Enough: Alternatives
For larger moves—especially those that cross between the domestic complex and the B Concourse, or when you’re short on time—O’Hare’s Airport Transit System (people mover) and bus routes are reliable. The transit system runs frequently, offers elevators for accessibility, and bypasses landside traffic. Rideshare and taxi services are available at terminal curbs, but they are typically used for off-airport travel rather than terminal-to-terminal connections.
Border, Security, and Time Considerations
International arrivals and departures can add steps to any walk. If you are meeting an arriving passenger or connecting to another airline, be aware that you may encounter U.S. Customs and Border Protection lines in Terminal 5 and possible secondary inspection. If your path crosses security level changes, plan for re-screening. Walking routes are usually safe and straightforward, but they can become slow during peak hours or when construction alters access.
Bottom Line
Walking between O’Hare terminals is practical within the domestic complex and for certain moves into and out of Terminal 5, but it is not a universal solution. For Terminal 1, 2, and 5 domestic gates, short walks are feasible and often faster than waiting for a shuttle. When you must reach the B Concourse or are on a tight schedule, using the Airport Transit System or a scheduled bus is the dependable choice. Always build in buffer time, follow official signage, and verify your specific terminals and gates on your boarding pass to choose the safest, most efficient route.
