Curbside check-in: International only
Check-in times
In most locations, you must be checked in:
At least 45 minutes before scheduled departure, for flights within the United States
At least 60 minutes before scheduled departure, for flights to or from airports outside of the United States
Peculiarities:
ORD can be affected by winter storms or very heavy air traffic; ground holds even at incoming flights' departures airports, are not uncommon at these times. Knock-on effects during lengthy IROPS can manifest themselves systemwide.
NOTE: AA has 66 gates at Terminal 3, and has added five more at Concourse.Alaska, Iberia, and Japan Airlines all depart AA T-3. Alaska has moved to Terminal 2. All international arrivals are at Terminal 5, many international departures as well. AB, BA, CX, EY, QR, RJ depart T-5.
International arrivals from Canada airports without USCBP pre-clearance are sometimes listed as arriving at "IAB" - International Arrivals Building. These aircraft's passengers will not arrive at T-3 as domestic passengers; by Federal law, they must be cleared by USCBP, and that facility is at T-5.
There is no airside connection T-3 <--> T-5; one must go landside and use the free "ATS" airport train. Flyers connecting to BA departing T-5 may use the airside shuttle bus departing near gates G17 and K20. Every half hour 11 am - 9 pm. Sign with orange dot. TTB SERVICE HAS BEEN TEMPORARILY SUSPENDED - TTB service takes travelers from the domestic terminals (1, 2, & 3) to Terminal 5 without having to exit security or be rescreened in Terminal 5 at the TSA checkpoint. [Still suspended as of 4/30/2022] Airside connection has been restored March 1, 2023 - SEE BELOW
Operating terminals and gates
Terminal 1 is used by All Nippon Airlines (Departures), Ethiopian (Departures), Lufthansa (Departures), and United.
Terminal 2 is used by Air Canada, Alaska,Delta, and previously US Airways, jetBlue, along with many United Express flights.
Terminal 3 is used byAlaska Airlines, American Airlines and for departures only by Iberia and Japan Airlines (exception: arriving international flights that have been USCBP cleared, e.g. originating in Canada or DUB, arrive at Terminal 3 as domestic flights). Other airlines flying domestically and not mentioned above are also handled in Terminal 3.
Concourse G is used mostly for American Eagle flights
Concourse H and K are used for mainline flights
Concourse K gates 12-20 are typically used for international flights
Concourse L is used mostly for American Eagle flights (as well as non-oneworld carriers)
Terminal 5 is now both an international and domestic terminal. Among the international flights, the following oneworld carriers depart and arrive here: British Airways, Cathay Pacific, Etihad Airways, Finnair, Qatar Airways, and Royal Jordanian; arriving international American Airlines, Iberia and Japan Airlines flights all arrive here as well. In fact, all arriving international passengers from places without pre-clearance will arrive at Terminal 5.
Domestic carriers now using Terminal 5 are: Delta and Delta Shuttle, Frontier, Southwest, and Sun Country.
Getting from terminal to terminal
Landside transfers are normally done by using the Airport Transit System train, which also connects to the airport car parks.The ATS is currently out of service with substitute buses operating at present. April 18, 2022: ATS service has been fully restored and is operating 24/7 daily.
Terminals are connected by frequent landside buses, and AA T3 - International T5 are connected by an airside Terminal Transit Bus (TTB). If you have a boarding pass for your connection (or a printed itinerary of flight confirmation), you can use this bus, boarding at G17 or K20 and arriving airside at T5 Gate M1. The TTB runs 7 days a week, 1100 / 11 am to 2100 / 9 pm while the ATS is shut down, but seasonally and with shorter hours when it is. At other times you must exit landside and use the landside bus.
If you arrive at O'Hare on an international flight you will arrive at Terminal 5. If you have a connecting domestic flight from T1-2-3. You must use the landside bus to T3 after you process Immigration and exit Customs. You will be required to pass through security at T3. Landside busses are frequent. May 1, 2022: Shuttle buses ended.
Airside:
walking corridors connect Terminals 1, 2 and 3 between terminals. (ATS landslide train must be used to connect to or from Terminal 5 outside of shuttle bus operating times.)
For those holding boarding passes on same day flights out of Terminal 5 (International Terminal), a shuttle bus will operate from T-3 (From Gates G17 and K20) to T-5 (Gate M13) between 11:30 am and 9:30 pm.[Still suspended as of 4/30/2022] March 1, 2023: Service restored. Connecting Traveler Information
Walking between terminals
Walking airside between terminals airside is possible (other than Terminal 5). There are no shortcuts and it can take significant time.
Arrival at the airport:
Within the U.S. as well as flights to Hawaii, Puerto Rico, and the U.S. Virgin Islands, check in:
At least 30 minutes prior to departure (if not checking bags)
At least 45 minutes prior to departure when checking bags
For flights to international destinations check in:
At least two hours prior to departure to complete all necessary international requirements
Minimum time for checking in and arriving at the gate
To better ensure an on-time departure, our goal is to close the jetbridge door 10 minutes before departure time. This allows all customers to board and stow their belongings. (AA may release your seat if you show up at your gates less than 15 minutes prior to scheduled departure.)
To retain your pre-reserved seat on a confirmed flight, make sure to follow the minimum check in and gate arrival times.*
Time to baggage delivery:
minimum 20 minutes
Security at ORD
May 2016: security queues have been quite lengthy at times, requiring up to an hour to pass through security, even at PreCheck queues. Options include:
If you have Flagship Check-In privileges, they will place you at the head of the security queue next to that check-in area.
You may choose to process security at Terminal 2 and walk airside to the AA gates (UA is only slightly better than AA). If you have CLEAR, you might want to consider clearing security here.
The mid-terminal Pre-Check line tends to be better than the one at priority security.
Note: coming out from International Terminal Arrivals immigration and customs, you are landside and may find yourself with two options: leave the building land side, or take the escalators or lifts to the ATS train platform to proceed to the other terminals or remote parking lot. To access the other terminals, you will have to process through TSA security.
What is the domestic to domestic or to international Minimum Connection Time (MCT)?
The minimum connect time at ORD, domestic to domestic or international, is 0:40 minutes. Domestic to international is easy if your international flight departs the AA terminal, but domestic to International terminal is comfortably done in 2:00 (not the official MCT, 1:15), because of the lack of connectedness between terminals. International arrival at Terminal 5 with flight departing Terminal 3, Global Entry is likely to allow 2:00 or even less, but non-U.S. or Canadian passport holders with checked baggage might use 3:00 as a better guideline.
If I am making an international to international connection, what is the process?
There is no international transit process in nearly all airports in the USA (MIA has a baggage exception for international to international). Arriving internationally, unless you have been pre-cleared, you must proceed through U. S. immigration (there are kiosks and a fast channel for Global Entry approved passengers), recover your baggage from the baggage carousel and proceed through U. S. Customs. There is a "green line" shortcut for passengers traveling only with carry-on baggage (no checked luggage) which is called "1 Stop" and there are Global Entry kiosks and there have fairly recently been dedicated Global Entry customs lines added, which ORD lacked for a very long time. Global Entry kiosks are located both in the central part of the main immigration hall area, as well as in the hall next to the 1-Stop exit.
Upon exiting Customs there is a bag drop facility; drop your checked baggage, exit to the landside arrivals area. Proceed to the the AA terminal on the ATS train, to counters or kiosks to get boarding passes for your ongoing travel, then proceed through TSA security to airside.

I walk pretty fast but I would think 5 minutes would be doable. Exit your gate, go right, Go right again to head into K gates. There are many signs.

At an average pace, it will be closer to 10 minutes, definitely doable in 5 though if you slalom through the slower moving passengers.

From G11 - exit the jetbridge, take the escalator up to the main level, walk to the base of G, walk over to the base of H/K, and then up to K13, I'd say 10-15 minutes myself. Be aware that gates can and do change.

Having gone between G11 and the H-K food court very recently, I would say K13 to/from G11 is comfortably possible within 10 minutes with a reasonably brisk walk without breaking a sweat. Wouldn’t advise people to count on it being done in 5 minutes, especially if coming into G11 and having valet tagged bags to claim at G11.

I'm going to be flying this weekend from a "G" gate. In the past flying through ORD, I've always used the H/K club which is pretty nice, but I see there is a "G" club. How is the "G" club (besides probably being smaller)?

Con: Often fewer food chocies but not the end of the world. The avocado toast/Guac station isn't there consistantly but when it is, no wait for that.

I find the estimated time in the app if you look at directions for ORD connections is generous. About right on at a stead walk but if you walk fast, you can cut that time off by a couple of minutes, maybe even 5 minutes on the longer walks

The valet bag retrieval from those regional flights can take 5-10 minutes which may be the biggest issue in time.

I've tried the app a few times just to see if it was accurate adn I'm an info junkie. I'm not a slow walker and generally beat the estimate but I'm passing a lot of people. If I have to wait for a bag at all on the regionals, I can occasionally be longer than the estimate. If I am coming through on a regional with a very tight connection, I check my bag.

obviously smaller (quite small) but I actually like the G lounge. Pros: generally less crowded and relaxing (H/K can be a zoo), if you like a quiet room, the one in G is completely closed off with a door and mostly empty (can be cold), no line at the bar if traveling later in the day. Great staff at the desk and generally no lines there either if you need anything.
Con: Often fewer food chocies but not the end of the world. The avocado toast/Guac station isn't there consistantly but when it is, no wait for that.

Note that both the L club and G club have shorter hours. They both close I believe at 7:00 p.m. or 7:15 pm.

So I have the this stupid reverse connection, flying to T5 domestic with DL connecting to IB international at T3, lol, I know, I had this expiring DL credit I needed to use...
I assume I take the airside bus T5 to T3 and no need to reclear security at T3, correct? I am flying HBO. I have at least a 3.5 hour layover.
