Chicago O’Hare International Airport Terminal 2 Map (Most Up-To-Date)
Chicago O’Hare Airport Terminal 2 is a compact “Y” layout: a central Departures hall with Security Checkpoint 5 feeding two airside arms—Concourse E (east/right) and Concourse F (west/left). The west edge links airside to Terminal 1 near the E1 connector; the east edge links airside to Terminal 3 through the Rotunda near F1. Landside, Departures is Level 2 above Baggage (Level 1) and the CTA tunnel level (Level 0).

Chicago O’Hare International Airport Terminal 2 Map Strategy
- Treat Terminal 2 as a moving target: verify your airline’s terminal before you head to Door 2A–2E (Alaska now Terminal 3; United can still be Concourse E gates in Terminal 2).
- Use the correct decision-tree early: staying airside only works for Terminal 5 if you can reach the Terminal Transfer Bus at Terminal 3 Gate G17 while it’s operating; otherwise commit to going landside to ATS and re-clearing security at Terminal 5.
- For Terminal 2 → Terminal 3 airside, lock onto the “F1 → Rotunda” connector and ignore landside exit doors in the main hall; the wrong peel-off is what triggers re-screening risk.
- For Terminal 2 → ATS (Terminal 5), remember the counterintuitive move: go up to the skybridge via the “ATS / Parking” vertical core (commonly near Doors 2C–2D), not down toward CTA/tunnels.

Terminal 2 remains fully operational but functions like a transition terminal under the O’Hare 21 program: airline locations have shifted (notably Alaska moving to Terminal 3 in late 2025) and United has expanded into Concourse E (E7–E14). Expect occasional narrowed corridors and wayfinding lag, especially near the Terminal 2–Terminal 3 hinge (Rotunda area) and connector approaches.

What is the exact airside walking route from Terminal 2 Concourse E to Terminal 3 Gate G17 (Terminal Transfer Bus pickup), including every required level change?
Walking takes about 13–15 minutes and stays on the main airside departures level until the final descent to Gate G17’s lower-level bus bay. The dealbreaker is avoiding the landside exit doors in the Terminal 2 main hall—stay in the secure corridor toward the Rotunda and Terminal 3 “G” gates.
| Step | Exact move (airside) | Landmark confirmation | Level change | Typical time |
|---|---|---|---|---|
| 1 | From Concourse E, walk back toward the Terminal 2 main hall (toward CP5) | Concourse opens into the E/F junction hub | None | 5–8 min |
| 2 | At the E/F junction, turn east toward the Terminal 3 connector | Pass the Concourse F entrance; continue past the United Club near F9 | None | 2–3 min |
| 3 | Continue to the corridor by Gate F1 into the Rotunda | Corridor narrows toward the circular Rotunda space | None | 1–2 min |
| 4 | Cross the Rotunda and follow signs for Terminal 3 / Gates G | Rotunda features (e.g., Cubs Bar & Grill / USO area) before you re-enter Concourse G | None | 2 min |
| 5 | Walk the full length of Concourse G to the far end, then peel to G17 access | Near the end by the higher-number gates (around G19/G21 area), look for “G17 / Terminal Transfer Bus” signage | None | 6 min |
| 6 | Go down to the G17 bus boarding area | Stairs/elevator marked for Gate G17 / bus pickup | Down 1 level | 1 min |
What is the exact airside entry point (landmark + junction) where a Terminal 2 passenger must peel off to reach the Terminal 3 concourse spine without accidentally going landside?
The peel-off happens at the Terminal 2 main hall’s east-side junction where the Concourse F entrance begins—your target is the corridor immediately by Gate F1 that leads into the Rotunda (Terminal 2–Terminal 3 connector). If you pass the F1 corridor and drift toward sliding glass doors, you’re about to go landside.
Standing in the post-security hub where Concourse E and Concourse F split, face the tarmac windows and turn east (left from the checkpoint view) so you walk past the Concourse F entrance and continue toward Gate F1. Keep the windows on your left/forward and ignore any right-hand doors that look like exits to baggage claim. The correct airside connector is the distinct hallway beside Gate F1 that funnels you into the circular Rotunda; once you enter the Rotunda, follow overhead signs for “Terminal 3 / Gates G, H, K, L” to land directly on Terminal 3’s Concourse G spine near G1/G2.
Which specific corridor segments inside or adjacent to Terminal 2 are currently blocked or non-passable, preventing an end-to-end walk in the secure area?
No Terminal 2 secure-side corridor segment is currently documented as fully non-passable end-to-end; the main impact is localized narrowing just outside Terminal 2 at the Terminal 3 hinge. The dealbreaker is that a true end-to-end “break” only happens during a sterile-area event—otherwise the connectors stay open.
- Terminal 3 main hall near the Rotunda/K1 interface: Service Animal Relief Area (SARA) section walled off; corridor narrowed but passable when moving between the Rotunda and Concourse G.
- Terminal 1 side near Gate B1 / Concourse C18B area: construction walls that can pinch pedestrian flow approaching the Terminal 1 complex, without closing the Terminal 2 ↔ Terminal 1 airside connector (the E1 → B6 link).
- Lower-level tunnel/infrastructure work zones: occasional constraints below the concourse level tied to satellite concourse projects; not a secure-side Terminal 2 “through-walk” blocker, but can create congestion pinch points near connector approaches.
Where exactly is the Terminal 2 security checkpoint entrance relative to departures doors and escalators, and which doors or lanes feed it?
The Terminal 2 security checkpoint (Checkpoint 5) intake is centered on Level 2 (Departures) between Doors 2C and 2D, with the queue starting in the central lobby just inside those vestibules. The left flank feeds CLEAR and TSA PreCheck; the center/right flank feeds general screening.
Checkpoint 5 sits in the middle of the Departures hall so the fastest approach is to enter from Door 2C or Door 2D and walk straight toward the roped queue. The vertical core for CTA/baggage connections is nearby in the same central zone, so if you come up from Level 1 you’ll typically emerge close to the Door 2C/2D area and then angle into the checkpoint lines. When facing the screening stations, CLEAR is positioned at the extreme left edge, PreCheck immediately to its right, and the general lanes occupy the center/right side of the checkpoint array.
From the CTA Blue Line O’Hare station, what is the exact walk path to reach Terminal 2 departures and check-in, including the first correct escalator or elevator choice?
Walking takes about 10–12 minutes, and the first correct vertical move is the escalator/stairs up from the CTA platform to the station concourse, then the escalator bank labeled for Terminal 2 at the end of the “Terminals 1, 2, 3” pedestrian tunnel. The dealbreaker is not stopping on Level 1 (Baggage Claim)—check-in is one floor higher.
From the Blue Line platform, head to the west end of the platform (front of train for arrivals), go up the escalator/stairs to the station concourse, pass through the fare turnstiles, and enter the wide pedestrian tunnel signed “Terminals 1, 2, 3.” Follow the tunnel as it slopes up; at the fork, keep center/straight for Terminal 2 (left trends Terminal 1, right trends Terminal 3). Take the escalator bank marked “Terminal 2” up into Level 1 Baggage Claim, walk a short distance inward (around Door 2C area), then immediately take the next escalator/elevator up to Level 2 Departures for ticketing/check-in counters.
From the Terminal 2 curb and drop-off, what is the fastest on-foot route to the ATS station used to reach Terminal 5, including the exact level transition point?
Walking takes about 4 minutes from the curb to the ATS station lobby, and the required move is going up from Level 2 Departures to the mezzanine/bridge level via the “ATS / Parking / Bridge to Garage” vertical core. The dealbreaker is not going down toward CTA tunnels—the ATS is reached by going up and across.
Enter Terminal 2 through the nearest central vestibule (best targets are Doors 2C or 2D). Inside the lobby, do not walk toward the ticket counters; instead, locate the vertical core signed “ATS / Parking / Bridge to Garage” positioned between the vestibules and the check-in area. Take the escalator or elevator up to the mezzanine/skybridge level, then cross the enclosed pedestrian bridge over the roadway into the parking structure. The bridge deposits you directly into the ATS station entrance area; follow signs to the platform for trains “Towards Terminal 5 / MMF.”
If a traveler is mistakenly dropped at Terminal 2 but needs Terminal 5, what is the exact minimum-step route to the correct Terminal 5-bound transport from that drop-off point?
The minimum-step route is Door 2C/2D → up to the skybridge → ATS train toward Terminal 5, with no attempt to walk the roadway. The dealbreaker is that road-walking to Terminal 5 is not a viable option; commit to ATS immediately.
| Step | Exact move from T2 drop-off | Landmark confirmation | Level change |
|---|---|---|---|
| 1 | From the curb, enter Terminal 2 at the nearest central vestibule | Door 2C or Door 2D signage on the canopy/doors | None (already Level 2) |
| 2 | Inside, find the vertical core signed “ATS / Parking / Bridge to Garage” | Between vestibule area and ticket counters; overhead “ATS / Parking” signs | Up to bridge/mezzanine |
| 3 | Cross the enclosed skybridge into the parking structure | Glass/enclosed bridge spanning the roadway | None |
| 4 | Enter the ATS station and go to the “Towards Terminal 5 / MMF” platform | ATS station lobby at end of bridge | None |
| 5 | Ride ATS to Terminal 5 and follow signs into T5 Departures | Terminal 5 station exit | None |
Where is the CLEAR lane or enrollment position for the relevant Terminal 2 checkpoint, and what are the two nearest fixed landmarks that confirm you’re at the correct entrance?
The CLEAR position is at the extreme left side of Terminal 2 Security Checkpoint 5 on Level 2 (Departures), immediately before the TSA PreCheck lane. The dealbreaker is that if you’re standing in the center/right general-screening queues, you’ve already missed CLEAR—CLEAR is far left.
CLEAR sits beside two reliable anchors: the United Premier Access check-in counters directly adjacent on the landside lobby side, and the architectural partition/wall that forms the boundary toward the corridor leading to Terminal 1. Approach from Doors 2C–2D, walk toward Checkpoint 5, then keep drifting left along the checkpoint face until you hit CLEAR kiosks/branding; TSA PreCheck is immediately to the right of CLEAR, while general screening begins further right under broader “Concourses E & F” style overhead signage.
Which exact gates in Concourse E correspond to the post-relocation gate groupings, and where do those gates sit on the Terminal 2 map?
Concourse E’s post-relocation grouping is E1–E4 for Air Canada at the root near the main hall, and E7–E14 for United/United Express along the main run of the concourse; the former Alaska area around E15–E17 is no longer Alaska’s base. Concourse E is the east/right arm of the Terminal 2 “Y,” branching from the central post-security hub.
- E1–E4: Air Canada zone, closest to the Terminal 2 main hall and CP5 (root of Concourse E).
- E7–E14: United / United Express zone, mid-to-down Concourse E (main body of the arm).
- E15–E17: Former Alaska area (vacated/swing use); Alaska now operates in Terminal 3 (G2 and G7), not in Concourse E.
Where is the shortest secure-side connector from Terminal 2 toward Terminal 1 or Terminal 3, and what is the exact path to reach it from the midpoint of Concourse E?
The shortest secure-side connectors from mid–Concourse E are the Terminal 1 connector just past Gate E1 and the Terminal 3 connector at the Gate F1 corridor into the Rotunda. From around Gate E10 (midpoint), both are typically reached in about 7–10 minutes depending on congestion.
| Toward | Connector location | Exact path from mid Concourse E (around Gate E10) | Level change | Typical time to connector |
|---|---|---|---|---|
| Terminal 1 | Airside corridor just past Gate E1, emerging near Terminal 1 Concourse B (by B6) | Walk from E10 back toward the Terminal 2 main hall (toward CP5) → keep going west toward the E1 end of Concourse E → pass Gate E1 → enter the window-parallel connector corridor | None | 7–10 min |
| Terminal 3 | Gate F1 corridor leading into the Rotunda, emerging into Terminal 3 Concourse G near G1/G2 | Walk from E10 back toward the Terminal 2 main hall (toward CP5) → at the E/F junction hub, turn east and walk past the Concourse F entrance → continue to Gate F1 → take the corridor into the Rotunda | None | 7–9 min |
If pedestrian flow across Terminal 2 is halted, what is the nearest alternate reroute to reach the opposite side, mapped by the closest connector nodes?
There is no redundant airside reroute inside Terminal 2 if the secure corridor is halted by a sterile-area event; the nearest workable alternate is landside via Baggage Claim and the underground pedestrian tunnels, which forces re-screening. The dealbreaker is that you must exit security—Terminal 2 doesn’t have a second secure-side cross-connection.
Exit the secure area to Terminal 2 landside, go down to Level 1 (Baggage Claim) and then to the Level 0 tunnel system, and use the “Terminals 1, 2, 3” pedestrian tunnels to reach the opposite terminal complex. If you need the west side (Terminal 1 access), aim for the tunnel route that resurfaces near Terminal 1 and then go up to Departures to clear security there; if you need the east side (Terminal 3 access), take the tunnel route that resurfaces near Terminal 3 and then go up to Departures to clear security at Terminal 3. The closest connector nodes that are bypassed by this move are the E1 airside connector (to Terminal 1) and the F1→Rotunda airside connector (to Terminal 3), both of which become unusable during the halt.
Where are the closest restrooms to the E7–E14 gate zone, and are they located pre-security or post-security?
The closest restrooms to Gates E7–E14 are post-security, with one small set near Gates E7/E8 and a larger restroom block back at the Concourse E stem by the main hall. The dealbreaker is that pre-security restrooms are landside and require exiting the secure area to use.
- Near Gates E7/E8: smaller restroom facility on Concourse E, a short walk from the E7–E14 United gate block; post-security.
- Main hall restroom block near the Concourse E stem: larger restrooms at the E/F junction area (often described around the crossover between E5 and F9); post-security.
