Chicago O'Hare International Airport ( IATA : ORD, ICAO : KORD, FAA LID : ORD ), also known as O'Hare Airport, Chicago O'Hare, or simply O'Hare ( / oʊ ˈhɛər / ), 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 metropolitan area, with Midway International Airport, which is about 10 miles ( 16 km ) closer to the Loop and serves as a secondary airport. It is operated by the City of Chicago Department of Aviation. O'Hare was the busiest airport in the world by the number of takeoffs and landings in 2014, ahead of Hartsfield -- Jackson Atlanta International Airport, which held the title from 2005 to 2013 ; however, it lost that title back to Atlanta a year later. Until 1998, O'Hare was also the world 's busiest airport by the number of passengers ; it was surpassed mainly due to limits the federal government imposed on the airport to reduce flight delays. As of 2016, O'Hare is the sixth - busiest airport in the world by passenger traffic, the third - busiest in the United States, and the busiest in the Midwest. O'Hare also has eight runways, more than any other major international airport. ORD covers 7,627 acres ( 3,087 ha ) of land. As of January 2017, O'Hare has direct service to 208 destinations, including 153 domestic destinations in the United States and 55 international ones in North America, South America, Asia, and Europe, making it an international gateway to much of the American midwest. It is among a select group of airports worldwide with the distinction of serving more than 200 destinations, along with Heathrow, Frankfurt, Atatürk, Amsterdam, Charles de Gaulle, Atlanta, Dallas / Fort Worth, Munich, and Dubai. O'Hare serves a major hub for United Airlines and American Airlines, as well as a hub for regional carrier Air Choice One, and a focus city for Frontier Airlines and Spirit Airlines. It is United Airlines ' largest hub in both passengers carried annually ( 16.6 million in 2016 ) and daily flights ( 585 on average ). It is also American 's third - largest hub, behind Dallas / Fort Worth International Airport and Charlotte Douglas International Airport, and third - largest by number of daily flights, operating 527 daily flights to 120 destinations, including 201 mainline flights daily. O'Hare was voted as 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 ). In contrast, Travel and Leisure magazine 's list of `` America 's Favorite Cities '' ( 2009 ) ranked Chicago 's Airport System ( O'Hare and Midway ) the second - worst for delays, behind the New York City airport system ( JFK, Newark Liberty, and LaGuardia ). O'Hare accounts for nearly 20 % of the nation 's flight cancellations and delays.

The city government investigated various potential airport sites during the 1930s, but made little progress until the 1940s. World War II See also : Illinois World War II Army Airfields O'Hare was constructed in 1942 -- 43 as part of a manufacturing plant for Douglas C - 54s during World War II. The site, at Orchard Place 18 miles northwest of downtown, 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. The airfield, known informally as Douglas Airport, initially had four 5,500 ft runways. 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, Chicago mayor Martin Kennelly established a formal board to choose the site of a new facility to meet future aviation demands. After considering various proposals, the board decided upon the Orchard Field site, and acquired most of the site from the federal government in March 1946. The military retained a small parcel of property on the site, and the rights to use 25 % of the airfield 's operating capacity for free. Ralph Burke, an engineer previously responsible for designing Meigs Field, designed an airport master plan based on a central complex of `` split finger '' terminals surrounded by ten runways. Burke 's final plan in 1947 called for the runways to be arranged tangentially at different headings so that no runway would cross another. This aspect of the plan was changed during the 1950s, as jet aircraft required longer runways, and the airport ultimately adopted a combination of overlapping parallel runways in different orientations. Financing of the airport was a major concern. Chicago did not have sufficient funding for the project and encountered difficulty in obtaining financial support from airlines and the federal government. 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's IATA code bearing no connection to the airport 's current name or metropolitan area. The United States Air Force used O'Hare extensively during the Korean War, at which time there was still no scheduled commercial service at the airport. In the early 1950s, debate raged in Chicago as to whether the Air Force should be removed from the site, or whether Chicago should sell the site back to the Air Force for use as a base. The Air Force eventually agreed to vacate O'Hare and relocate to a new base in the Chicago area.

Traveling with him, LT `` Whitey '' Feightner was redirected to land 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, and his F7U became the first aircraft to land there. Scheduled passenger flights started in 1955 and at the end of 1956 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 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 move all of their services to O'Hare until better highway access and other 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 km ) 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. In July 1962 the last fixed - wing scheduled airline flight in Chicago moved from Midway to O'Hare. President John F. Kennedy attended a dedication ceremony in 1963. After Kennedy was assassinated later that year, the section of Interstate 90 between downtown Chicago and O'Hare was renamed in his honor. The arrival of Midway 's 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. By 1967, Midway was nearly abandoned, with barely 4,400 airline operations, but Chicago city officials reached an agreement with airlines, in late 1972, to shift some services back to Midway to ease the crowding at O'Hare. ( Midway enjoyed another revival after startup carrier Midway Airlines began low - cost service there in 1979 -- 80. ) O'Hare remained the world 's busiest airport ( by airline operations ) until 1998. Pre-deregulation service 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, and via 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 ( other than Canada ) used Concourses B and C in Terminal 1. Braniff, Eastern, Northwest, Continental and Piedmont used Concourse D in Terminal 2. United was the main tenant in Concourses E and F of Terminal 2, with Ozark also using gates in Concourse 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 ). Concourse A was, at one time, a satellite terminal for commuter airlines at the west end of the terminal complex. Post-deregulation developments In the 1980s, after deregulation, TWA replaced Chicago with St. Louis as its main mid-continent hub. Although TWA had one of the largest Chicago operations during the late 1970s, its operation was losing $25 million a year under intense competition from United and American. TWA attempted to compete with an all - coach service to the West Coast at the lowest prices in the market, but American and United eventually matched TWA 's fares during the recession of 1979 -- 81, and TWA ended the service. In 1982, TWA swapped three of its Chicago gates for five of American 's St. Louis gates, setting the stage for TWA 's transition to St. Louis. 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. The nationwide hubs established at O'Hare in the 1980s by United and American 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, which included ticketing and baggage claim areas, as well as 29 additional gates, was officially dedicated on August 4, 1987, with Mayor Harold Washington in attendance. 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. 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 m ) 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 m ) Admirals Club was also added to the concourse. Delta moved from Terminal 3 to Terminal 2 in 2009 to align its operations with merger partner Northwest. Continental moved from Terminal 2 to Terminal 1 in 2010 before 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, for grounds maintenance. This plan resulted from difficulties in reaching certain areas around the runways 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.

( August 2016 ) See : O'Hare Air Reserve Station 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 United States Air Force 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 ( `` 1993 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 Greater Rockford Airport, `` 55 miles northwest of O'Hare International Airport. '' The 1993 Commission stated that the city of Chicago would be required to bear the costs of moving these units. The 1995 Base Realignment and Closure Commission ( `` 1995 Commission '' ) modified the recommendation by stating that the units should instead be moved to 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 1995 Commission 's report 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 United States Air Force facilities were redeveloped for air cargo and general aviation. This was partly necessitated by the abrupt closure of Meigs Field in 2003, which diverted general aviation in Chicago to O'Hare and Midway. Today, Signature Flight Support services private aircraft in this area. Infrastructure Location Most of O'Hare Airport is in Cook County, but a section of the southwest part is in DuPage County. The airport is within a section of the City of Chicago contiguously connected to the rest of the city by 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. Runways Runway layout at ORD 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 using three of the four parallel runways, with the fourth runway being used for takeoffs. Before 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, 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 33 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 glide slope, the vertical component. Runway 33 ( former 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 opened 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 15 / 33 ( former 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. On August 19, 2015, Runway 14L / 32R was closed. The redevelopment, when completed, will remove the two northwest -- southeast runways ( former 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, three of the four new runways have been constructed ( 9L / 27R, 10C / 28C, and 10R / 28L ), and one of the two extensions ( 10L / 28R ) is complete. In the earlier airfield layout, the former 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 15 / 33 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. On September 25, 2008, a 2,857 - foot ( 871 m ) extension to 10L / 28R opened. On May 2, 2013, airport diagrams published by the FAA depicted the runway previously designated 10 / 28 as 10L / 28R. 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. On October 15, 2015, Runway 10R / 28L was commissioned. The new 7,500 - foot runway will be used almost exclusively for landings toward the east up until 10 p.m. daily. The runway will increase arrival and departure rates at O'Hare by about 25 percent in good weather, all while handling only 5 percent of all daytime flights annually over the next five years. However, the runway sits on the southernmost part of the airfield which aligns roughly with Irving Park Road in Bensenville. Since the runway is several miles from the passenger terminals, the average taxi time is estimated at about 20 minutes. The cost of the runway and a taxiway was $516 million, and they are being controlled by a new air - traffic control tower that cost $41 million to build, according to the FAA and the Chicago Department of Aviation. Intra-airport Transportation Main article : Airport Transit System Airport Transit System with Hilton Hotel in Background Passengers within the airport complex can travel via 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 beginning in summer 2015, underwent a US $240 million enhancement adding 15 new cars, upgrading the previous infrastructure, and extending the line to a new consolidated rental car facility where lot F is situated. Other facilities Nippon Cargo Airlines has its Americas regional office on the O'Hare property. A large air cargo complex on the southwest side of the field opened in 1984, replacing most of the old cargo area, which stood on the site now occupied by e Terminal 5. This complex sits right in the path for new runway 10C / 28C, and will 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 Terminals 2 and 3 for the use of traveling military personnel, 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. Along with several other airports around the world, O'Hare has used portions of some of its land to allow urban bee keeping. Intended to raise the environmental profile of airports -- with 75 hives, O'Hare is the world 's largest airport bee keeper, as of 2015. Airport hotel In the vicinity of Terminals 1 - 3 and the parking lots A-C, there is an on - site airport hotel operated by Hilton Hotels & Resorts. Terminals A terminal map of O'Hare Airport Passengers stranded overnight are provided a secure area with dimmed lights, cots, pillows, blankets, and toiletries. 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. With the exception of flights from destinations with U.S. Customs and Border Protection preclearance, all inbound international flights arrive at Terminal 5, as the other terminals do not have screening facilities. Several carriers, such as American, Iberia, Lufthansa and United, with outbound international flights depart from Terminals 1 and 3. This arrangement requires that passengers disembark at Terminal 5 and then, crews tow the empty plane to another 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 allow airside connections, Terminal 5 is separated from the other terminals by a set of taxiways that cross over the airport 's access road, requiring passengers to exit security, ride the Airport Transit System, then reclear security in either direction. Terminal 1 United Airlines Terminal 1, Concourse B An underground pedestrian walkway connects Concourse B to Concourse C, illuminated by a neon light show United Airlines Terminal 1, Concourse C Terminal 1 is used for United Airlines flights, including all mainline flights and some United Express operations, as well as flights for Star Alliance partners Lufthansa and All Nippon Airways. Terminal 1 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 - ins, baggage claims, and security screenings 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 ramp, and is connected to Concourse B via an underground pedestrian tunnel under the ramp. The tunnel originates between gates B8 and B9 in Concourse B, and ends on Concourse C between gates C17 and C19. The tunnel 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 ) in Terminal 1 and Concourses E & F ( at gate E4 ) in Terminal 2. It operates three United Clubs in Terminal 1 : one on Concourse B near gate B6, one located near gate B16, 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. Concourse B features an extension at its northern end ( gates B18 - B22 ) commonly called the `` banana gates '' due to the extension 's narrow curved shape. The final gate, B22, branches off into three separate jetways for three regional jet parking positions. Terminal 1 houses All Nippon Airways 's Chicago office. Terminal 2 Terminal 2 houses Air Canada, Delta Air Lines and Delta Connection domestic flights, and most United Express operations ( Check - in for all United flights is done in Terminal 1 ). Terminal 2 has 43 gates on two concourses. Concourse E -- 17 gates Concourse F -- 26 gates There is a United Club in Concourse F near gate F8, and a Delta Sky Club in 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, reconfiguring the holding rooms, and constructing a United Club to replace the current lounge. US Airways operated out of Terminal 2 until it moved operations to Terminal 3 in July 2014, to be co-located with its merger partner American Airlines. Check - in for US Airways remained at Terminal 2 until September 16, 2014, when ticket counters relocated to Terminal 3. Terminal 3 American Airlines Terminal 3 Main Hall American Airlines Terminal 3, Concourse H Terminal 3 houses all American Airlines flights, as well as departures for select Oneworld carriers including Iberia and Japan Airlines, plus unaffiliated low - cost carriers. Terminal 3 has 75 gates ( 5 to be added ) on four concourses : Concourse G -- 25 gates Concourse H -- 17 gates Concourse K -- 16 gates Concourse L -- 17 gates ( 5 to be added ) Concourses G and L house most American Eagle operations, while Concourses H and K house American 's mainline operations. American 's Oneworld partners Japan Airlines, and Iberia depart from K19 and non-affiliated Alaska Airlines operates from H4. Concourse L is used also for flights operated by Frontier Airlines, Spirit Airlines, JetBlue, Virgin America, and Air Choice One. The City of Chicago and American Airlines have agreed to an extension of the L Concourse to add five new gates. The gates are expected to be used primarily for American Eagle 's Embraer E-175 fleet. American has agreed to pay roughly $55 to $75 million and the gates are expected to be completed by 2018. The airline operates three Admirals Clubs in Terminal 3 : one located in the crosswalk area between gates H6 and K6, one after security before Gate L1, and one in Concourse G across from gate G8. American also has a Flagship Lounge ( currently branded as International First Class Lounge ) located near gate K19. The Flagship Lounge is scheduled to move underdeath the Admirals Club located in the crosswalk area between gates H6 and K6 in late 2017. Terminal 5 ( International ) Terminal 5, with flags of countries around the world Aircraft lined up at Terminal 5 Terminal 5 houses all of O'Hare's international arrivals ( excluding flights from American Airlines and United Airlines from destinations with U.S. border preclearance. ) Other destinations with U.S. border preclearance, including flights operated by Aer Lingus and Etihad Airways, arrive at Terminal 5, but are treated as domestic arrivals. With the exception of select Star Alliance and Oneworld carriers that board from Terminal 1 or Terminal 3 respectively, all non-U.S. carriers except Air Canada depart from Terminal 5. Terminal 5 has 21 gates ( 9 to be added ) on one concourse : Concourse M -- 21 gates ( 9 to be added ) Terminal 5 has several airline lounges, including the Air France - KLM Lounge, British Airways First Class Galleries and Business Class Terraces Lounges, Korean Air Lounge, Scandinavian Airlines Lounge, Swissport Lounge, and Swiss International Air Lines First Class Lounge and Business Class 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. Terminal 5 is run by Westfield Management. O'Hare recently developed a gate capable of accommodating the world 's largest passenger aircraft, the Airbus A380. On February 10, 2016, the Chicago Department of Aviation approved the construction to build out a gate that could handle the Airbus aircraft. The new gate, M11a is the only gate capable of handling the Airbus A380 and, like other gates in Terminal 5, is designated as `` common use, '' meaning no specific airline has exclusive control over it. Emirates and British Airways expressed interest in using their A380s on routes involving O'Hare. The gate became operational on July 19, 2016, with Emirates being the first airline to use it. British Airways announced on August 8, 2017 that the A380 would fly to O'Hare on one of its two daily flights starting May 8, 2018. Previous Terminal and concourses Old Terminal 1 Terminal 1 was the first international terminal. It opened in 1955, it became the international terminal in 1963 and was demolished in 1984 to make way for the current Terminal 1. It was replaced by a temporary Terminal 4 built in 1984. The terminal was connected to Terminal 2 by a glass - enclosed hallway. It had a Y shaped concourse similar to Concourses H / K in Terminal 3. Concourse a ( Terminal 1 ) Old Terminal 1 also had a satellite Concourse A that served commuter airlines. Among the airlines that used to operate from this terminal were Air France, El Al, Icelandair, Mexicana de Aviación, Pan Am and Sabena. Concourse D ( Terminal 2 ) A Concourse D in Terminal 2 previously existed and served as the concourse for AirCal, Air Wisconsin, Braniff, Continental, Eastern, Frontier Airlines, Northwest Orient, People Express, Piedmont and United Express until it was demolished in 1988 to make room for the current Terminal 1 concourses. It consisted of 12 gates. Terminal 4 Terminal 2 Check - in Due to the construction of Terminal 1 for United, all international arrivals and some international departures were relocated to a temporary Terminal 4 from 1984 until 1993. Terminal 4 was located on the ground floor of the main parking garage ; departing and arriving passengers were transported by bus to and from their aircraft. The terminal served many international carriers during this time, but was inadequate both in terms of operating area and bus loading / unloading capacity. Ground for the new $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. The `` Terminal 5 '' name was used for this new terminal in order to avoid confusion with the old Terminal 4. Since the opening of Terminal 5, Terminal 4 has been converted into the airport 's facility for regional transit buses, hotel shuttles, and other ground transportation. The CTA Blue Line was extended to the airport in 1984. However, the terminals are still numbered as if Terminal 4 had been kept as one of the airport 's terminals.

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.

Rail Chicago ' L ' The Blue Line provides ' L ' service between O'Hare and Forest Park, departing from an underground station accessible by pedestrian tunnels from Terminals 1, 2, and 3, and the ATS from Terminal 5. 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. Metra Commuter trains from the Metra North Central Service stop at the O'Hare Transfer station, which is connected to the Airport Transit System via a shuttle bus. Trains run only on weekdays. Airport express The City of Chicago is looking into a plan for an express train that would take tourists, locals, and other travelers from downtown Chicago to O'Hare International Airport in about 20 minutes, which is half the time it takes on the City 's Blue Line. If an express train does get built, one - time tickets would likely cost around $30 to $35. Less expensive monthly passes and family discounts might also become available. The City will look for a private company to cover construction costs and operate the system, but it 's likely public money would go into building stations at the airport and downtown if the project moves ahead. The city says an engineering firm will spend the next 10 months evaluating potential routes, drafting designs and coming up with a construction timeline and cost estimate, then put it out for bid in 2017. In the early 1990s, the idea of a 20 - minute O'Hare express train service has been proposed. Some plans included bypass tracks on the CTA Blue Line that run down the middle of the Kennedy Expressway as well as use of a Union Pacific Railroad right - of - way near the Kennedy. However no plans were ever materialized. Car 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 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. Bus 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. Cellphone lot A cellphone lot can be reached via the Car Rental return / Bessie Coleman Drive exit off the I - 190. Signs direct drivers to the new cellphone lot. The lot is on the west side of Bessie Coleman Drive, across from car rentals, one half mile north of the exit. An information display provides aircraft arrival time updates. Car rental O'Hare International Airport offers a variety of options for vehicle rentals. Each rental car company offers free, 24 hour shuttle service. The shuttles pick up at the Arrivals curb front located on the lower level outside of Baggage Claim. Each terminal has designated areas on the outermost curb front where shuttles board. Modernization plan 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 acquiring 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 15 / 33 ( former 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 m ) 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. existing runway new runway removed runway Phase 1 ( Complete, runway 18 / 36 was closed before ) Phase 2 ( Complete ) Phase 3 ( In August 2015 14L / 32R was closed. Runway 10R / 28L opened 10 / 15 / 15 ) Final runway configuration Resistance and alternatives See also : Proposed Chicago south suburban airport 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, especially with the opening of an Amtrak station directly west of Mitchell providing service from Chicago Union Station via the Hiawatha Service seven times per day ; O'Hare and Mitchell have no direct rail link. Accidents and incidents The following is a list of crashes that happened on planes en route to / from O'Hare.

On May 25, 1979, American Airlines Flight 191, a McDonnell Douglas DC - 10 to Los Angeles International Airport lost its left wing engine while taking off from Runway 32R, then stalled and crashed into a field on the opposite side of Touhy Avenue from present - day Runway 9L / 27R, killing all 271 people on board and two people on the ground. The crash remains the deadliest single - aircraft crash in United States history, and the deadliest aviation disaster in U.S. history before the September 11, 2001 attacks. On March 19, 1982, a United States Air Force KC - 135 Stratotanker crashed upon approach to O'Hare 40 miles ( 64 km ) northwest of the city ( near Woodstock ), killing 27 people on board. On August 10, 1986, American Trans Air Flight 131 caught fire on the ramp, destroying the plane. Nobody was killed. On October 31, 1994, American Eagle Flight 4184 from Indianapolis International Airport was circling over northwestern Indiana while waiting for a landing slot at O'Hare to open up when its wings iced up, causing the plane to dive nose - first into a cornfield, killing all 68 people on board. On February 9, 1998, American Airlines Flight 1340 crashed upon landing from Kansas City, injuring 22 passengers. On April 1, 1999, an Air China Boeing 747, Flight 9018, taxied onto an active runway at O'Hare during the takeoff of Korean Air Flight 36, another Boeing 747. Flight 36 averted a collision by taking off early and missing the Air China aircraft by 75 feet. There were 8 people on the Air China cargo plane and 379 on the Korean Air flight. On March 24, 2014, a Blue Line train derailed in the airport 's ' L ' station when it overran a bumper block. 32 people were injured, as the train rolled into the airport subway station onto a platform and crashed into an escalator. On October 28, 2016 at approximately 2 : 35 p.m. local time, American Airlines Flight 383, a Boeing 767 - 300, aborted takeoff after what was said to be a blown tire followed by a problem with its right engine. The aircraft was evacuated on the runway via emergency slides as a large fire engulfed the right engine and wing. Nine people were injured, 2 seriously. http://www.ntsb.gov/news/press-releases/Pages/pr20161104.aspx See also Golden Corridor, for the region of commerce and industry surrounding O'Hare and extending west, along the Jane Addams Memorial Tollway Proposed Chicago south suburban airport United States Air Force portal World War II portal Chicago portal Aviation portal References This article incorporates public domain material from the Air Force Historical Research Agency website http://www.afhra.af.mil/.
