Chicago O'Hare International Airport (IATA: ORD, ICAO: KORD, FAA LID: ORD), also known as O'Hare Airport, O'Hare Field, Chicago International Airport, or simply O'Hare, is an international airport located on the Far Northwest Side of Chicago, Illinois, 17 miles (27 km) northwest of the Loop. It is the primary airport serving the Chicago area, with Midway Airport, about 10 miles (16 km) closer to the Loop, serving as a secondary airport.
O'Hare is the world's busiest airport in number of takeoffs and landings -- a title it reclaimed in 2014, beating out Hartsfield-Jackson Atlanta International Airport (which had the title from 2005-2013). Until 1998, O'Hare was the busiest airport in the world in number of passengers. Mainly due to limits imposed on the airport by the federal government to reduce flight delays. As of 2014, O'Hare is the busiest airport in the world by traffic movements, and is the third busiest airport in the United States and sixth busiest in the world by passenger traffic.
O'Hare is currently a major hub for American Airlines and United Airlines, as well as a hub for regional carrier Air Choice One and a focus city for Frontier Airlines and Spirit Airlines. It is the second largest passenger carrying hub for United after Houston's George Bush Intercontinental Airport carrying 15.3 million passengers annually, and largest by number of daily flights, operating a total of 585 flights daily. O'Hare is American's second largest hub, behind Dallas/Fort Worth International Airport, and third largest by number of daily flights, operating a total of 201 mainline flights daily.
As of September 2014, O'Hare has direct service to a total of 210 destinations, including 153 domestic destinations in the United States and 57 international destinations in South America, Asia and Europe. With 200+ destinations, O'Hare is among a select group of airports worldwide with that distinction, including Frankfurt Airport, Amsterdam Airport Schiphol, Charles de Gaulle Airport, Hartsfield–Jackson Atlanta International Airport, Dallas/Fort Worth International Airport, Munich Airport, and Dubai International Airport.
O'Hare has been voted the "Best Airport in North America" for 10 years by two separate sources: Readers of the U.S. Edition of Business Traveler Magazine (1998–2003) and Global Traveler Magazine (2004–2007). Travel and Leisure magazine's 2009 "America's Favorite Cities" ranked Chicago's Airport System (O'Hare and Midway) the second-worst for delays, New York City's airport system (JFK, Newark Liberty, and LaGuardia) being the first. O'Hare currently accounts for over a sixth of the nation's total flight cancellations.
It is operated by the City of Chicago Department of Aviation. Most of O'Hare Airport is in Cook County, but a section of the southwest part of the airport is in DuPage County. The Cook County portion is located within a section of the City of Chicago contiguously connected to the rest of the city via a narrow strip of land about 200 ft (61 m) wide, running along Foster Avenue, from the Des Plaines River to the airport. This land was annexed into the city limits in the 1950s to assure the massive tax revenues associated with the airport would go to the city. The strip is bounded on the north by Rosemont and the south by Schiller Park.

World War II
O'Hare was constructed in 1942–43 as part of a manufacturing plant for Douglas C-54s during World War II. The site was chosen for its proximity to the city and transportation. The two million square foot (180,000 m²) factory needed easy access to the workforce of the nation's then-second-largest city, as well as its extensive railroad infrastructure. Orchard Place was a small nearby farming community.
Douglas Company's contract ended in 1945 and though plans were proposed to build commercial aircraft, the company ultimately chose to concentrate production on the west coast. With the departure of Douglas, the airfield took the name of Orchard Field Airport, the source of its three-letter IATA code ORD.
In 1945, Orchard Field was chosen by the city of Chicago as the site for a facility to meet future aviation demands. Matthew Laflin Rockwell (1915–1988) was the director of planning for the U.S. Army Corps of Engineers and responsible for the site selection and design. He was the great grandson of Matthew Laflin, a founder and pioneer of Chicago.
In 1949, the airport was renamed "O'Hare International Airport" to honor Edward O'Hare, the U.S. Navy's first flying ace and Medal of Honor recipient in World War II. Its IATA code, "ORD", remained unchanged, however, resulting in O'Hare being one of the rare instances of an airport's three-letter designation bearing no connection to the airport name or metropolitan area (with other rare instances including Orlando International Airport's IATA code "MCO" or Toronto Pearson International Airport's code of "YYZ").
By the early 1950s, Midway Airport, Chicago's primary airport since 1931, had become too crowded despite multiple expansions and could not handle the planned first generation of jets. The city of Chicago and the FAA began to develop O'Hare as the main airport for Chicago's future.
In 1953, while traveling to an airshow at Naval Air Station Glenview in Chicago, Illinois, Blue Angels pilot LT Harding MacKnight experienced an engine flameout in his F7U Cutlass, forcing him to make an emergency landing at NAS Glenview. Traveling with him, LT "Whitey" Feightner was redirected to make his landing at O'Hare. The runway had just been completed and was covered with peach baskets to prevent aircraft from landing until it was opened. LT Feightner was told to ignore the baskets and land on the new runway. As a result, LT Feightner's F7U became the first aircraft to land on the new runway for O'Hare.
Commercial passenger flights started in 1955 and by the following year O'Hare was served by American, BOAC, Braniff, Capital, Delta, Eastern, North Central, Pan Am, TWA and United, along with freight airlines Riddle and Slick. O'Hare also opened a $1 million "Skymotive" terminal for corporate aircraft in 1955, the first of its kind.
Growth was slow at first. By 1957 Chicago had invested over $25 million in O'Hare, but Midway remained the world's busiest airport and airlines were reluctant to relocate all of their services to O'Hare until better highway access and other capital improvements were completed. The April 1957 Official Airline Guide shows 10 weekday departures on United, 9 on American, 6 on Capital, 3 Eastern, 3 TWA, 2 Delta, 2 North Central, and 1 Braniff. Also three weekly Pan Am and one weekly BOAC (Air France and Lufthansa were at Midway). O'Hare's first dedicated international terminal opened in August 1958. By April 1959 the airport had expanded to 7,200 acres (29 km2) with new hangars, terminals, parking and other facilities. The expressway link to downtown Chicago, then known as the Northwest Expressway, was completed in 1960.
Ground was broken for the main terminal complex (of which Terminals 2 and 3 remain today) on April 1, 1959. The complex, designed by C. F. Murphy and Associates, opened on January 1, 1962.
All fixed-wing scheduled airline service in Chicago moved from Midway to O'Hare by July 1962. President John F. Kennedy attended a dedication ceremony in 1963; after he was assassinated later that year, the section of Interstate 90 between downtown Chicago and O'Hare was renamed the Kennedy Expressway. The arrival of Midway's former traffic quickly made O'Hare the world's busiest airport, serving 10 million passengers annually. Within two years that number would double, with more people passing through O'Hare in 12 months than Ellis Island had processed in its entire existence. In late 1972, Chicago city officials reached an agreement with airlines to shift some services back to Midway in order to ease the overcrowding at O'Hare. Despite this, O'Hare remained the world's busiest airport until 1998. In the late 1960s Midway was nearly abandoned; it enjoyed a revival after startup carrier Midway Airlines began low-cost service there in 1979–80.
American Airlines, United Airlines and Trans World Airlines had many routes to the West Coast, Northeast and Midwest. TWA flew to Europe nonstop from O'Hare starting in 1958. Northwest Orient Airlines flew to the Northeast, Pacific Northwest, Florida and Hawaii, as well as service through Alaska to Japan and the Far East. Their 747 to Tokyo was O'Hare's first nonstop to Asia, in 1977. Delta Air Lines served the Southeast and Midwest.
During this era international flights used Terminal 1. United, Ozark, Braniff, Eastern, Northwest, Continental and Piedmont used Terminal 2 (concourses D, and current concourses E and F). In Terminal 3, Concourse G served TWA and Air Canada, and Concourses H and K served American, Delta and North Central (later merged into Republic Airlines).
In the 1980s, after deregulation, TWA replaced Chicago with St. Louis as its main mid-continent hub. Northwest likewise shifted to a Minneapolis and Detroit-centered network by the early 1990s following its acquisition of Republic Airlines in 1986. On January 17, 1980, the airport's weather station became the official point for Chicago's weather observations and records by the National Weather Service.
United and American both established nationwide hubs at the airport in the 1980s, which continue to operate today. United developed a new US$500 million Terminal 1 ("The Terminal of the Future" or "Terminal of Tomorrow"), which was designed by Helmut Jahn and A. Epstein and Sons, with Turner Construction as the construction manager, and Thornton Tomasetti serving as the structural engineer. It was built between 1985 and 1987 on the site of the old international terminal. Ground was broken for the new terminal complex in March 1985. The terminal opened with 13 gates on June 15, 1987. The terminal was officially dedicated on August 4, 1987 with Mayor Harold Washington in attendance at the dedication ceremony, and the ticketing and baggage claim areas, as well as 29 more gates, were opened. Concourse D of Terminal 2 was demolished in order to make way for the rest of the terminal, which was completed in December 1988. American renovated its existing facilities in Terminal 3 from 1987 to 1990. These renovations were designed by Kober/Belluschi Associates, Inc. and Welton Becket & Associates. Delta maintained a Chicago hub for some time, and opened a new Concourse L, initially known as the "Delta Flight Center", designed by Perkins and Will and Milton Pate & Associates, in Terminal 3 in 1983, but ultimately closed its Chicago hub in the 1990s.
Due to the construction of Terminal 1 for United, international flights were relocated to a temporary Terminal 4 from 1984 until 1993. Terminal 4 was located on the ground floor of the main parking garage; international passengers would check in there and be taken directly to their aircraft by bus. Ground for the new US$618 million International Terminal was broken on July 11, 1990 with airline executives and government officials, led by Mayor Richard M. Daley and U.S. Secretary of Transportation Samuel K. Skinner, in attendance. The new Terminal 5, designed by Perkins and Will in conjunction with Heard & Associates and Consoer Townsend & Associates partially opened on May 27, 1993 with its two lower levels completed to handle all international arrivals. The rest of the terminal, including the departures level, opened on September 30, 1993. Since the opening of Terminal 5, Terminal 4 has been made into the airport's facility for CTA buses, hotel shuttles, and other ground transportation; the T4 designation may be used again in the future as new terminals are developed. The CTA Blue Line was extended to the airport in 1984.
Total annual passenger volume at O'Hare reached 30 million in 1968, 40 million in 1976, 60 million in 1990 and 70 million in 1997.
A $80 million renovation of Concourse G in Terminal 3 designed by Teng & Associates, Inc. began in the spring of 1999 and finished in the spring of 2001. The concourse was enlarged into a 144,500-square-foot (13,420 m2) facility with 25 remodeled gates. Six large "sky vaults", huge skylights atop V-shaped columns that bring natural light into a previously confined space, were constructed. A new 4,138-square-foot (384.4 m2) Admirals Club was also added to the concourse.
Delta moved its operations from Terminal 3 to Terminal 2 in 2009 in order to align its operations with merger partner Northwest Airlines. Continental moved from Terminal 2 to Terminal 1 in 2010 prior to merging with United.
In 2013, the Chicago Department of Aviation appropriated a $19,500 two-year contract to use livestock, specifically goats, sheep, llamas, and burros, to assist with grounds maintenance. This plan was implemented due to difficulties in reaching certain areas on the runway property with traditional lawn mowing machines due to rocky or sloped terrain. About 25 animals were recruited chiefly to clear growing vegetation around the approximately 120-acre (49 ha) space around the runways. A secondary reason for the introduction of the animals, especially the llamas and burros, was to reduce interference from wildlife such as coyotes and birds that may come when smaller prey settle in unmaintained, grassy areas.
United States Air Force use
The original Douglas Aircraft C-54 Skymaster transport manufacturing plant on the northeast side of the airport became a United States Air Force Air National Guard and Air Force Reserve facility after World War II. It was used by the USAF from 1947 until 1999 as O'Hare Air Reserve Station, making the airport a joint civil-military airfield during this period.
The 1993 Base Realignment and Closure Commission recommended the closure of O'Hare Air Reserve Station as proposed by the municipal government of the City of Chicago and the transfer of both the Illinois Air National Guard's 126th Air Refueling Wing (126 ARW) and its KC-135 aircraft, and the Air Force Reserve Command's 928th Airlift Wing (928 AW) and its C-130 aircraft to new facilities to be constructed at Scott AFB, Illinois. The 126 ARW moved from the former O'Hare Air Reserve Station to Scott AFB, Illinois in 1999 as recommended by the Base Realignment and Closure Commission's Report to Congress in conjunction with the closure of the Air Force Reserve Command and Air National Guard facilities at O'Hare. Instead of moving to Scott AFB, subsequent BRAC action directed that the 928 AW be inactivated and its C-130 aircraft reallocated to other Air Force, Air Force Reserve and Air National Guard units.
Following the closure of the O'Hare Air Reserve Station, the former USAF facilities were redeveloped for air cargo and general aviation. Today, Signature Flight Support services private aircraft in this area.
On October 17, 2013 O'Hare opened Runway 10C-28C. The opening of this eighth runway marked the completion of the Phase II expansion project. O'Hare landings have been reconfigured to predominately use a triple arrival scheme utilizing three of the four parallel runways, with the fourth runway being used for takeoffs.
Prior to the opening of 10C-28C, the new runway, 9L/27R which opened in November 2008, O'Hare had seven runways in three roughly-parallel sets. The longest is Runway 10L–28R, 13,001 by 150 feet (3,963 m × 46 m). Runways 9L, 10C, 10L, 14L, 14R, 27L, 27R, 28C and 28R have Category III instrument landing systems (ILS), allowing trained aircrews to conduct landings with as little as 600 feet (180 m) of horizontal visibility. All other runway approaches except 4L and 32L have full Category I ILS. Runway 4L is seldom used for landings and has a localizer, the horizontal guidance component of an ILS system, but does not have a glideslope, the vertical component. Runway 32L was permanently closed to landings when the section south of the crossing with Runway 10L/28R was closed due to 10C/28C construction.
Prior to the runway reconfiguration, all of O'Hare's runways intersected each other with the exception of 4R/22L. This created problems in inclement weather, busy times, or high winds, and several near-collisions. The redevelopment, which essentially eliminates most active runway intersections, is intended to reduce collision hazards and delays.
The field started with four clustered runways; in March 1950 all were 5,500 to 5,750 feet (1,680–1,750 m) long. Runway 14 (later 14L) became 7,345 feet (2,239 m) around 1952; the 8,000-foot (2,400 m) runway 14R/32L opened in 1956 and became 11,600 feet (3,500 m) long in 1960. The 10,000-foot (3,000 m) 9R/27L (now designated 10L/28R) opened in 1968 and 14L became 10,000 feet (3,000 m) long around the same time. 4R/22L opened in 1971 and the new 9L/27R in 2008. In 2003 the fourth original runway (18/36) closed; its short length, lack of use, and placement no longer justified certification. Runway 18/36 is now taxiway M on airport charts.
The redevelopment, when completed, will remove the two northwest–southeast runways (14/32 L/R), construct four additional east–west runways (10C/28C, 10R/28L, 9L/27R, and 9C/27C), and extend the existing east–west runways (9R/27L and 10L/28R). The two existing northeast–southwest (4/22 L/R) runways will be retained. Currently, two of the four new runways have been constructed (9L/27R, 10C/28C), and one of the two extensions (10L/28R) has been completed.
In the earlier airfield layout, 32L was often used for takeoffs in a shortened configuration. Planes reached the runway at taxiway T10 (common) or taxiway N, formerly M (not common). This shortened the runway but allowed operations on runway 10L/28R to continue without restriction. The full length of the runway was available upon request, though with the extension of 10L/28R it was usually not needed. In May 2010 runway 14R/32L was permanently shortened to 9,685 feet (2,952 m) and it now starts at taxiway N.
O'Hare has a voluntary nighttime (2200–0700) noise abatement program.
The runway reconfiguration at O'Hare will also improve the airport for future Airbus A380 service. On July 5, 2007 the runway previously designated 9R/27L became runway 10/28. On May 2, 2013, that same runway (10/28) became 10L/28R. On August 30, 2007, runway 9L/27R became 9R/27L.
Runway 10C/28C was commissioned and opened for regular use on October 17, 2013. On October 17, 2013, airport diagrams published by the FAA depicted the runway as open.
Access within the airport complex can be accomplished using a 2.5 mi (4 km)-long automated people mover that operates 24 hours a day, connecting all four terminals landside and the remote parking lots. The system began operation on May 6, 1993, and will soon experience a US$240 million enhancement to add 15 new cars, upgrade the current infrastructure, and to extend the line to a new consolidated rental car facility where lot F is currently situated.
A large air cargo complex on the southwest side of the field was opened in 1984, replacing most of the old cargo area, which stood where Terminal 5 now exists. This complex sits right in the middle of the footprint for new runway 10C/28C, and is to be replaced by a new facility located on the northeastern portion of the airfield.
The new North Terminal Air Traffic Control Tower was completed in September 2008 and commissioned for use on November 20, 2008. The new tower was designed by DMJM Aviation-Holmes & Narver Aviation Partners JV (design principal Jose Luis Palacios).
The USO has a facility in Terminal 2 for the use of military personnel arriving or departing, as well as military recruits going to Recruit Training Command, which has a booth at O'Hare to coordinate transportation to Naval Station Great Lakes for Naval recruits arriving via airplane.
O'Hare has four numbered passenger terminals with nine lettered concourses and a total of 182 gates. Two or more additional terminal buildings are envisioned; there is the possibility of a large terminal complex for the west side of the field, with access from I-90 and/or the Elgin-O'Hare Expressway, if the runway reconfiguration is completed and passenger numbers require additional terminals.
All international arrivals at O'Hare (except for flights from destinations with Customs preclearance) arrive at Terminal 5, as the other terminals do not have Customs facilities. Since a number of carriers that have international flights from O'Hare, like United and American, are based in Terminal 1 or Terminal 3, those airlines will have their aircraft offloaded at Terminal 5 and then, after passengers are offloaded, the plane is towed empty back to a gate at the airline's assigned terminal for boarding. This is done, in part to make connections for passengers transferring from domestic flights to international flights easier, since while Terminals 1, 2, and 3 are connected by an airside corridor, Terminal 5 is not, requiring passengers to exit security, ride the Airport Transit System, then reclear security in either direction.
Terminal 1 is used for United Airlines mainline flights, some United Express operations, as well as flights for Star Alliance partners Lufthansa and All Nippon Airways. It has 50 gates on two concourses:
- Concourse B – 22 gates
- Concourse C – 28 gates
Concourses B and C are linear concourses located in separate buildings parallel to each other. Concourse B is adjacent to the airport roadway and houses passenger check-in, baggage claim and security screening on its landside and aircraft gates on its airside. Concourse C is a satellite terminal with gates on all sides, in the middle of the tarmac, and is connected to Concourse B via an underground pedestrian tunnel under the tarmac, which is illuminated with a neon installation titled Sky's the Limit (1987) by Canadian artist Michael Hayden, which plays an airy and very slow-tempo version of "Rhapsody in Blue".
United also runs a post-security shuttle bus service between Concourse C (at Gate C9) and Concourses E & F (at Gate E2A) in Terminal 2. There are three United Clubs in Terminal 1: one on Concourse B near gate B6 on the same level as departures, one located near gate B18, and one on Concourse C near gate C16. There is also a United First International Lounge and United Arrivals Suite in Concourse C near gate C18.
Terminal 2 houses Air Canada as well as Delta Air Lines and Delta Connection domestic flights (Delta's wintertime service between O'Hare and Paris operates from International Terminal 5 as the gates in Terminal 2 do not accommodate the Boeing 767-300ER normally assigned to that route). Terminal 2 is also used for most of the United Express operations, although check-in for these flights is conducted at Terminal 1. There is a United Club in Concourse F near gate F4, and a Delta Sky Club on Concourse E near gate E6. United Continental Holdings, United's parent company, is currently upgrading its facilities at Terminal 2, including constructing 10 new jet bridges for the regional flights, reconfiguration of the holding rooms, and a newly constructed United Club as a replacement of the current club.
US Airways previously operated flights from Terminal 2 until they began operating from Terminal 3 with its partner airline American. Check-in for US Airways remained at Terminal 2 until September 16, 2014, in which ticket counters were relocated to Terminal 3. A Concourse D previously existed and served as the concourse for AirCal, Braniff, Continental, Eastern, Northwest Orient, Piedmont and United Express until it was demolished in 1988 to make room for the current Terminal 1 concourses.
Terminal 2 has 42 gates on two concourses:
- Concourse E – 16 gates
- Concourse F – 26 gates
Terminal 3 houses all American Airlines and US Airways flights, as well as departures for select oneworld carriers including Air Berlin, Iberia, and Japan Airlines, plus unaffiliated low-cost carriers. Terminal 3 has 80 gates on four concourses:
- Concourse G – 26 gates
- Concourse H – 21 gates
- Concourse K – 22 gates
- Concourse L – 11 gates
Concourse G primarily houses American Eagle operations, while Concourses H and K house American's mainline operations. Concourse L, the previous home of Delta, also is used for some American Eagle flights, with additional gates used for mainline American operations (L8 and L10) as well as for codeshare partners Alaska Airlines and Westjet. Low-cost carriers Spirit Airlines, JetBlue, Virgin America and Air Choice One operate the odd-numbered gate side of Concourse L beginning at gate L3. Japan Airlines and Iberia operate out of gate K19 and Air Berlin operates out of gate H15. Frontier Airlines operates out of Gates L1 and L2. There are two Admirals Clubs in Terminal 3: one located in the crosswalk area between gates H6 and K6, and a smaller one in Concourse G across from gate G8. American also has a Flagship Lounge located near gate K19.
International Terminal 5
Terminal 5 has 21 gates and is designated on airport maps as Concourse M.
All of O'Hare's international arrivals (excluding flights from destinations with U.S. border preclearance (except for preclearance flights operated by Aer Lingus and Etihad Airways) are processed at Terminal 5. With the exception of select Star Alliance and Oneworld carriers that board from Terminal 1 or Terminal 3, all non-US carriers depart from Terminal 5, as do certain domestic low-cost carriers (Delta is the only major US carrier that uses Terminal 5, for its nonstop wintertime flight to Paris).
Terminal 5 has several airline lounges, including the Air France VIP Lounge, Alitalia Sala Freccia Alata, British Airways First and Terrace Lounge, Korean Air Lounge, Scandinavian Airlines Business Lounge and Swiss International Air Lines Lounge. The airport's U.S. Customs and Border Protection facility is located at the arrival (lower) level.
Terminal 5 underwent a $26 million renovation designed by A. Epstein and Sons International, Inc., which began in July 2012, which involved adding dining and retail post-security, including many Chicago-based restaurants and brands, updated design, and a re-engineered layout. The project was completed on April 4, 2014.
Airlines and destinations
Note: All international arrivals, except for arrivals from airports with U.S. customs preclearance, are serviced at Terminal 5, regardless of the listed departure terminal.
1 United's check-in and baggage claim is located at Terminal 1 but uses Concourses E and F, which are part of Terminal 2.
Future Passenger Airlines and Destinations
EVA Air will start passenger flights to Chicago-O'Hare in Summer of 2016. Philippine Airlines has also expressed interest in starting non-stop service between Manila and Chicago, sometime in 2015 or 2016. Air Serbia could add Chicago sometime in the second half of 2015.
There are two main cargo areas at O'Hare that have warehouse, build-up/tear-down and aircraft parking facilities. The Southwest Cargo Area, adjacent to Irving Park Road, accommodates over 80% of the airport's all-cargo flights, divided among 9 buildings in two tiers. The North Cargo Area, which is a modest conversion of the former military base (the 1943 Douglas plant area), also receives air freighters. It is adjacent to the northern portion of Bessie Coleman Drive.
Two satellite cargo areas have warehouse and build-up/tear down facilities, but aircraft do not park at these. Freight is trucked to/from aircraft on other ramps. The South Cargo Area is along Mannheim Road. The East Cargo Area, adjacent to Terminal 5, was formerly the airport's only cargo section but has now mostly evolved into an airport support zone.
The Southwest Cargo Area partially lies in the path of one of the new runways (10C/28C). The redevelopment of the airfield will entail moving/replacing this primary cargo hub.

Trains from the Blue Line of the Chicago Transit Authority's 'L' terminate at the airport from an underground station, accessible by pedestrian tunnels from Terminals 1, 2, and 3. The station opened on September 3, 1984. Trains run 24 hours a day, 7 days a week, providing connection via downtown Chicago to Forest Park.
Road vehicles enter and exit via I-190, which branches off I-90 (the Kennedy Expressway) leading to downtown Chicago. Cars may also access the airport locally from Mannheim Road, the airport's eastern boundary. Aside from cargo access on its south side, all airport traffic travels through the east side of the airport. Local residents sometimes refer to I-190 as "the world's busiest Cul-de-sac" as a result of the one way access.
Taxi and Limo Services also provide transportation to/from Chicago O'Hare Airport. Fares vary based on traffic, average fares from O'Hare to downtown Chicago are $30–$40.
Regional buses, taking passengers to Indiana, Iowa, and Wisconsin arrive and depart from the Bus / Shuttle Center. It is located on the ground level of the Main Parking Garage, accessible by pedestrian tunnels from Terminals 1, 2, and 3.
Cell Phone Lot
A cell phone lot can be reached via the North Mannheim Road exit off the I-190. Signs direct drivers to the Economy Parking Lot F/Cell Phone Lot. An information display provides arrival time updates.
O'Hare's high volume and crowded schedule can lead to long delays and cancellations that, due to the airport being a major hub, can have a ripple effect on air travel across North America. Official reports rank O'Hare as one of the least punctual airports in the United States based on percentage of delayed flights. In 2004, United Airlines and American Airlines agreed to modify their flight schedules to help reduce congestion caused by clustered arrivals and departures. Because of the air traffic departing, arriving, and near the airport, air traffic controllers at O'Hare and its nearby facilities are among the leaders in the world in terms of number of controlled flights handled per hour.
City management has committed to a $6 billion capital investment plan to increase the airport's capacity by 60% and decrease delays by an estimated 79 percent. This plan was approved by the FAA in October 2005 and will involve a reconfiguration of the airfield and addition of terminal space. The plan includes the addition of four runways, the lengthening of two existing runways, and the decommissioning of two existing runways in order to give the airfield six parallel runways in a configuration similar to that used at Dallas/Fort Worth International Airport, Los Angeles International Airport, and other large modern hub airports. This plan was very controversial as the added improvements, at the time they were proposed, were expected to increase the airport's air traffic capacity only slightly, given existing FAA rules. Additionally, the southernmost new runway would require the city acquire additional land, which was extremely controversial as residents did not want to move.
The Modernization Plan is now being implemented; an additional runway and Air Traffic Control Tower were commissioned on November 20, 2008. The new north runway, designated 9L/27R, initially served as a foul weather arrival runway, addressing one of O'Hare's primary causes of delays, but now serves as one of three runways that can be used simultaneously for landings. An extension of Runway 10L/28R (formerly 10/28, and prior to that 9R/27L) to 13,001 feet (3,963 m) was commissioned for use on September 25, 2008, facilitating the shortening and eventual closure of the 13,000 feet (4,000 m) Runway 14R/32L. At the same time, the FAA redesigned the departure routes for both O'Hare and Midway airports, increasing the number from three shared by both airports to five from each airport. With the new runway's opening, O'Hare's maximum aircraft arrival capacity increased from 96 planes per hour to 112 planes per hour; United Airlines's senior vice president of operations, Joseph Kolshak, told The Wall Street Journal that within a month of the runway's opening, "they were consistently hitting that."
As part of Mayor Rahm Emanuel's $7.3 billion infrastructure modernization plan, announced in March 2012, the airport would receive an additional $1.4 billion over three years to hasten the completion of the modernization effort. The plan calls for accelerated completion of the fourth and final new runway as well as resumed negotiations with the airport's major airlines in an effort to boost O'Hare's overall capacity by 300,000 passengers per year by 2015.
The modernization plan has required the acquisition of 126 acres (51 ha) of land in Des Plaines, Illinois; construction of runway 27R and the control tower cost $457 million and involved the rerouting of a creek and 14,000,000 cubic yards (11,000,000 m3) of fill to build up an embankment.." 2,800 residents had to be relocated, as well as a cemetery with 900 known graves. The program ultimately is expected to expand the airport's capacity to over 3,800 operations per day, up from the present capacity of 2,700, and will vastly increase passenger throughput. It will also improve the ability of very large aircraft such as the Airbus A380 to operate.
Flight caps in place since 2004 expired on October 31, 2008. American Airlines eliminated over 60 daily flights at O'Hare because of rising fuel prices. United announced similar cutbacks. Recent worldwide economic difficulties further complicate the forecasts for airport demand.
After initially opposing the Modernization plan, DuPage County has endorsed the plan citing the creation of jobs, commercial development, and the ability of O'Hare to regain the status as busiest airport.
Resistance and alternatives
The neighboring communities of Bensenville and Elk Grove Village have been centers of resistance to the expansion plan, due to their proximity to the airport and because some of their residents and businesses would be required to relocate. Bensenville and Elk Grove Village formed the Suburban O'Hare Commission to fight the expansion. So far, they have not had much success. The commission did receive a temporary injunction against portions of the city's expansion project; it was soon overturned, however. The Suburban O'Hare Commission has also been instrumental in pushing for a third regional airport in south suburban Peotone, which it claims would alleviate congestion at O'Hare. No airline has committed to the proposed airport, however, and planning efforts moved very slowly during 2007–08. In 2008, Elk Grove Village ended resistance. They received assurance that a proposed highway would not be built through their business park. In November 2009, Bensenville officially ended all resistance to the expansion, ceasing all legal challenges against the city of Chicago. They received a one-time $16-million payment from Chicago. The city of Chicago also faced a five-year court battle to acquire a small, historical cemetery located within the space of their planned runway expansion. A settlement was finally reached in December 2012, between St. John United Church of Christ in Bensenville and the city of Chicago. The city agreed to pay the church $1.3 million for the 5-acre (2.0 ha) parcel on the west side of the airport, which included a 2-acre (0.81 ha) burial ground established by the church in 1849. All told, 1,494 bodies were disinterred from the St. Johannes Cemetery and reburied at various cemeteries throughout the region.
In 1995, the Chicago/Gary Airport Compact was signed by the cities of Chicago and Gary, Indiana, creating a new administration for the Gary/Chicago International Airport just across the state line. While markedly smaller than the proposed Peotone site, this airport already has more land and a longer main runway than Midway Airport. Gary is also many miles closer than Peotone to downtown Chicago. In addition public transportation is already in place to the Loop via the South Shore Line. Indiana and the FAA have provided significant funding for a Gary runway expansion, currently under construction. The issue here is a large portion of the revenue that is generated would go to the state of Indiana as opposed to Chicago and the state of Illinois, the very entities the airport would mainly serve.
Chicago Rockford International Airport (RFD) in Rockford, Illinois has also marketed itself as an alternative for congestion at O'Hare. It is at least a 1-1/2-hour trip to Rockford from the Chicago Loop. Currently there is no direct transportation service from downtown Chicago or O'Hare to Rockford airport, but airline service at the airport continues to grow. Larry Morrissey, the current mayor of Rockford, has pushed for a high-speed rail connection between the two airports to make the Rockford airport a more convenient alternative to O'Hare.
General Mitchell International Airport (MKE) in Milwaukee has consistently attempted to increase its usage by Chicago and Northern Illinois customers. There is a direct Amtrak rail service connecting Chicago with Mitchell Airport. The trains operate seven round trips each day, taking under 75 minutes from the Chicago loop.
