O'Hare International Airport (IATA: ORD) is one of the biggest and busiest airports in the world. It serves the city of Chicago and the rest of the Chicagoland area, with connecting flights to smaller cities throughout the Midwest.
This is no Changi, no Kansai; in other words, it's nobody's favorite airport. O'Hare is huge, but it's from an era before airports had much in the way of amenities, and it's been stretched beyond capacity for a while now. Although safety has never been a concern, O'Hare has one of the worst on-time records of any major airport. In the winter, snow and ice storms can cause delays, and during the summer, heavy winds can make take-off and landings dangerous. These weather conditions sometimes cause air traffic control at O'Hare to hold traffic from smaller airports from even taking off. However, most of the world's airlines fly through O'Hare, so international travellers and those making transfers aren't likely to have much of a choice. The title of the world's busiest airport oscillates between O'Hare and Altanta's Hartsfield-Jackson. Those travelling to the area can use Chicago's Midway or Milwaukee's General Mitchell International (connected to the Loop via the Amtrak Hiawatha train service). Alternatively, travellers may consider the Airport Express (dead link: January 2023) operated by Coach USA/Wisconsin Coach Lines, connecting General Mitchell International, the Milwaukee Intermodal Station and points in-between.
There are multiple TSA Pre lines in terminal 3, so travellers who have paid for this service can clear security very quickly even in high traffic conditions.
O'Hare has four passenger terminals. Terminals 1-3 handle domestic traffic and a few international departures. Terminal 5 handles all international arrivals and international departures that are not covered by Terminals 1-3. (Terminal 4 is something of a fnord, its temporary space since re-appropriated as the shuttle bus depot; the name has been set aside for potential future expansion). The O'Hare 21 plan is already changing this, however - more details below..
United Airlines has its main hub at O'Hare, since its corporate offices are located in downtown Chicago. O'Hare is also a major hub for American Airlines. As such, a rule of thumb is that Terminals 1 and 2 are dominated by United and its alliance partners; Terminal 3 is given over to American and its partners, and only Concourse L of Terminal 3 and several gates in Concourse E of Terminal 2 are for everybody else.
Here is a detailed list of terminals and airlines. The terminal color is the same here as it is on signage and maps at the airport.
Terminal 1
Concourse B: United Airlines
Concourse C: United, ANA (departures), Lufthansa (departures, except for LH 437 to Munich)

With the exception of some flights from airports with US border preclearance, such as those from major Canadian airports, all international arrivals are processed at Terminal 5 regardless of the departure terminal of the airline.
For passengers arriving on international flights, Immigration and Customs (dead link: January 2023) formalities typically take 15-30 minutes, but can take over 2 hours at peak times. The busiest times are in the afternoon, and the full statistics can be seen here.
Passengers transferring between international flights should note that there are no special transit facilities, which means that even if you have an immediate connecting flight, you have to pass through Customs and Immigration. After you clear customs, but before you exit into the public area, there are some check-in counters run by the major mainline carriers for you to check your bags that have already been checked through to the final destination, so you don't have to lug your bag to Terminals 1-3. For details of entry and visa requirements see get in section of United States page. Passengers arriving on international flights and transferring to another international or domestic flight will have to go through security again.
For passengers transferring between from domestic flights (or from international flights from airports with US border preclearance), Terminals 1-3 are connected to each other both landside and airside, so if your luggage is checked through, you do not need to clear security again. Terminal 5 is in a completely separate area and not physically connected to Terminals 1-3, so you will have to exit the restricted area and go through security again after transferring using the AirTrain.
This major renovation plan, named due to its planned full completion in 2021, is already making an impact in the airport. For example, the first new gates in two decades (the L Stinger concourse for American Eagle regional jets), the temporary closure of the ATS for renovation and extension, the new Multi-Modal facility, and the move of all Delta and Frontier flights - even domestic ones - to Terminal 5 have already happened.
The long term plan is that the Terminals 1-3 complex will become a unified Global Terminal with customs implementation as well as TSA and landside amenity improvements. This Global Terminal will make O'Hare the first North American airport to be built around the airport alliances as United and Star Alliance carriers as well as American and Oneworld airlines will move there while Delta and their SkyTeam partners will move to the current Terminal 5, which will be extended to meet the demand.
The CTA Blue Line terminates at the space-age station for O'Hare, designed by the firm of architect Helmut Jahn. Trains run 24 hours a day, as frequently as every six minutes during peak periods and as infrequently as every half-hour overnight. The trip to the Loop should take about 48 minutes, but never cut things close with the CTA. The station is located beneath the Bus/Shuttle Center, closest to Terminal 2 but easily accessible by underground passages, with moving walkways, from Terminals 1 and 3. Those arriving at or departing from Terminal 5 (international) must take the automated Airport Transit System between Terminals 2 and 5. The cost of the train from O'Hare is $5 instead of the regular $2.50 anywhere else in the city. When taking the CTA to O'Hare, it's recommended to board the train at the front in the O’Hare direction, as the entrance is at the front of the train (back of the train in the Forest Park direction). You do not need to pay the extra fare upon exiting the station.
Metra North Central Service trains stop at the "O'Hare transfer" station, located adjacent to parking lot F (with shuttle bus service connecting to the ATS at the Remote Parking stop). The train reaches Chicago's Union Station in approximately 30 minutes, but service is infrequent, operates only on weekdays and is concentrated in the peak commute direction. In the future, Metra-ATS transfers will be direct at a new consolidated rental center.
Pace routes 250 (Dempster Street for Evanston and Skokie) and 330 (Mannheim/La Grange) stop at the terminus of the Airport Transit System in parking lot E.
Several bus companies run scheduled and charter services to other communities; these usually drop passengers off at the departure-level curb and pick passengers up at the Bus/Shuttle Center.
Chicago taxis (dead link: January 2023) charge a metered rate based on time and distance. Expect to pay around $45 (plus tip) from O'Hare to the Loop. It is illegal for Chicago taxis to charge a non-metered flat rate except for special shared-ride services. Taxi drivers rarely participate in shared-ride services.
Except for a few suburbs immediately adjacent to the airport, Chicago taxis charge one and a half times the meter rate for non-Chicago destinations. Most suburban taxi companies have flat-rate taxi service to their respective suburbs. It is illegal for a suburban taxi to take you from O'Hare to a point within the City of Chicago. American Taxi, Universal Taxi and 303 Taxi are three large suburban taxi associations that have taxis stationed near the airport. But the suburban taxis cannot come to the airport unless you call them after you arrive.
Of the many shuttle/limo services, Go Airport Express vans are the most commonly seen doing the rounds of downtown hotel pick-ups. Fares to the downtown business district are $32/46/54 (plus tip) for a party of one/two/three persons, with a discount for a return ticket if bought in advance and lower fares for children under 14.
Ride app pick-up zones are on the upper level (the departure level) in Terminals 1–3 for domestic arrivals, and on the lower level of Terminal 5 for international arrivals.
The Coach USA provides transfer service to Midway Airport for $25 (plus tip), with almost hourly departures from all the terminals. Service is offered daily 4:50AM-8:50PM. Chicago taxis' metered rates for the Midway/O'Hare trip are in the vicinity of $65.
If time is not of the essence, the O'Hare to Midway trip can be made via CTA 'L' lines for $5 (and only $2.25 from Midway to O'Hare). Take the CTA Blue Line from the lower level of the domestic terminals to the Clark/Lake stop and follow the signs on the platform to go upstairs to the CTA Orange Line which goes to Midway. There is no charge for changing trains at Clark/Lake. The typical time is about an hour and a half, although extra time should be allowed for delays.
Access to O'Hare's terminals is via I-190, which originates near the interchange between I-294 (the Tri-State Tollway) and I-90 (the Northwest Tollway to the northwest and the Kennedy Expressway to the east). From downtown Chicago, follow I-90/94 northwest, continue on I-90 when I-94 splits off, then follow I-190 into the airport, which splits eventually into arrival (lower-level) and departure (upper-level) roadways serving Terminals 1, 2, and 3 in turn. For Terminal 5, exit on Bessie Coleman Drive. This exit also serves numerous rental car companies and the economy parking lots. To drop off a passenger without the harrowing experience of navigating the departures roadway, try Kiss n'Fly: follow signs for remote lot E where you can leave your friend at the terminus of the Airport Transit System, just a short ride away from the terminals.
Most major car rental companies have gigantic lots at O'Hare and offer complimentary shuttle buses to and from the passenger terminals.
O'Hare runs a parking hotline (+1-773-686-7530 ) and broadcasts parking information on 800 AM radio within two and a half miles of the airport. Parking at O'Hare is no simple affair. If you're the sort of person who likes to meet friends at baggage claim with a cordial "Come on, run with those bags!" you'll be glad to know that parking in the main garage is free for stays of under 10 minutes. For the rest of us...
If leaving a vehicle at the airport during a trip, numerous options are available.
Passengers may walk between Terminals 1, 2, and 3 both land-side (prior to clearing security) and air-side. The distance can be considerable; make sure to allow adequate time for layovers between different terminals.
United Airlines runs an air-side shuttle bus between Gate E2A in Terminal 2 and Gate C9 in Terminal 1 (convenient for people going from a United Express flight to a Star Allaince flight). There is also a bus stopping at gates G17, K20 and L24 in Terminal 3 before going to Terminal 5, allowing you to bypass the security checkpoint there. Due to immigration and customs processing, you can't take the bus back.
The ATS is undergoing renovations and only operates 10:30AM-10:30PM daily. Replacement shuttle buses go to each terminal, economy parking lot and the Metra station. Full service is expected to resume in 2022.
O'Hare has an automated, land-side, transit system cleverly called Airport Transit System or ATS. Stops are made at all four terminals as well as at remote parking lot E. This is the only way to reach the three domestic terminals and the Blue Line station from the international terminal, which means that passengers connecting to or from a Terminal 5 flight should allow abundant time for border formalities, inter-terminal transit, and a second security screening. There is no charge for the use of the ATS.
O'Hare doesn't have much in the way of amenities, but there are at least a few distractions: O'Hare in the movies
Scenic beauty it ain't, but O'Hare does have a cinematic legacy. For example, in the first two Home Alone movies, the McAllister family departed for Paris and Miami in American Airlines' Terminal 3. If you feel like playing with a TalkBoy, chasing a man in a Burberry coat, or running on to the jetway of your flight moments before you leave, here's the place.
O'Hare has plenty of places to eat, most of which won't provide you with an experience beyond keeping you alive through your upcoming flight. You'll pay more than you should for meals you won't remember anything about, save for the grease. There are a few, though, that stand out enough to be worth hunting down, namely The Berghoff and Tortas Frontera, which are good enough to make a delayed flight seem like a good opportunity.
There are a few options for booze in O'Hare. Some restaurants, including Billy Goat and The Berghoff, also have liquor licenses. As with food, options are more limited in the international terminal.
For passengers departing on international flights there are some somewhat limited duty free shopping possibilities:
COVID-19 testing for travel is available at O'Hare.
Many hotels serving O'Hare are actually located in the nearby suburbs of Schiller Park, Elk Grove Village, Mount Prospect, Des Plaines, and most of all in Rosemont. Amenities are fairly standard, with an eye toward business travelers. The area's upscale hotels are all in Rosemont, with the lone exception of the Hilton at the airport:
All hotels run shuttles to and from the airport. Some run on a schedule and do regular pick-ups, while others have to be called from the airport concierge. Shuttle stops are clearly sign-posted. Make sure the shuttle is going to your specific hotel — Marriott, for example, runs separate shuttles for each of its brands. A taxi should cost $10-15 at the most.
O'Hare is well known for weather issues that cause flights to be canceled, particularly in the winter and summer months. If you get stuck at O'Hare and need a hotel room for the night there is a service, Airport Accommodations, that provides discounted rates at full service hotels in the airport area that provide free shuttle service. Call their 24/7 customer service center at +1-800-935-5995 and they will help you find a room in the airport area. They do not charge for their services.
If you're driving to a hotel, get on I-190, the small expressway that operates to/from the airport. Most hotels are clustered on Mannheim Road or River Road, which have exits from the expressway, or off roads that connect with Mannheim going north (Higgins, Touhy) or south (Irving Park). I-190 merges with I-90/94, which heads to the center of Chicago.
Cheap hotels near O'Hare tend to be cheap for a reason — don't be shy about asking to see the room first.
If you're going to spend a lot of money on a hotel and you plan to be in town for more than one night, you'll have a much better time in downtown Chicago. That said, these hotels are big and do a lot of business.
Chicago's Far Northwest Side is the closest part of the city to O'Hare. While it does have some charms, the most popular attractions for tourists are much further on, in the Loop, Near North, and Near South.
