Indira Gandhi International Airport is the primary international airport serving New Delhi, the capital of India, and the National Capital Region (NCR). The airport, spread over an area of,[5] is situated in Palam, Delhi, 15km (09miles) southwest of the New Delhi Railway Station and 16km (10miles) from New Delhi city centre.
Named after Indira Gandhi (1917–1984), the former Prime Minister of India, it is the busiest airport of India in terms of passenger traffic since 2009.[6] It is also the busiest airport in the country in terms of cargo traffic. In the financial year of 2023-24, the airport handled 7.36 crore (73.6 million) passengers, the highest ever in the airport's history.[7] As of 2024, it is the tenth-busiest airport in the world, as per the latest rankings issued by the UK-based air consultancy firm, OAG.[8] [9] It is the second-busiest airport in the world by seating capacity,[10] [11] [12] having a seating capacity of over 36 lakh (3.6 million) seats, and the busiest airport in Asia by passenger traffic, handling over 6.55 crore (65.5 million) passengers in 2023. In fact, it is routinely one of the busiest airports in the world, according to the Airports Council International rankings.[13]
The airport was operated by the Indian Air Force before its management was transferred to the Airports Authority of India.[14] In May 2006, the management of the airport was passed over to Delhi International Airport Limited (DIAL), a consortium led by the GMR Group.[15] In September 2008, the airport inaugurated a 4430m (14,530feet) runway. With the commencement of operations at Terminal 3 in 2010, it became India's and South Asia's largest aviation hub. The Terminal 3 building has a capacity to handle 3.4 crore (34 million) passengers annually and was the world's 8th largest passenger terminal upon completion.[16] The airport inaugurated a 4400m (14,400feet) runway and the Eastern Cross Taxiways (ECT) with dual parallel taxiways in July 2023.[17] The airport uses an advanced system called Airport Collaborative Decision Making (A-CDM) to help keep takeoffs and landings timely and predictable.[18]
The other airport serving NCR is the Hindon Airport, which is much smaller in size and primarily handles regional flights out of the city under the UDAN Scheme.[19] The former airport, which used to be the primary airport of NCR, Safdarjung Airport is now used mainly by VVIP helicopters and small charter helicopters due to its short runway. To stimulate the increasing traffic, a second airport, Noida International Airport is being constructed to offset the load of Indira Gandhi International Airport.[20]
Palam Airport had a peak capacity of around 1,300 passengers per hour.[5] In 1979–80, a total of 30 lakh (3 million) domestic and international passengers flew into and out of Palam Airport.[21] Owing to an increase in air traffic in the '70s and the '80s, an additional terminal with nearly four times the area of the old Palam terminal was constructed. With the inauguration of this new international terminal, Terminal 2, on 2 May 1986, the airport was renamed as Indira Gandhi International Airport (IGIA).[5]
The old domestic airport (Palam) is known as Terminal 1 and was divided into separate buildings – 1A, 1B, and 1C. Blocks 1A and 1B were used to handle international operations while domestic operations took place in Block 1C. Block 1A and 1B later became dedicated terminals for domestic airlines and are currently closed down. It is planned that they will be demolished after the construction of newer terminals. Block 1C was also turned into a domestic arrivals terminal, and was rebuilt and opened on 24 February 2022. The newly constructed domestic departures block 1D is now used by all domestic low-cost airlines (IndiGo, and SpiceJet). There is also a separate technical area for VIP passengers. The domestic arrivals terminal 1C was demolished and rebuilt into a brand-new domestic arrivals terminal. For this expansion work, GoAir and select flights of IndiGo were moved to Terminal 2 as well as select flights of SpiceJet and IndiGo to Terminal 3.
In October 2001, Canada 3000 commenced a flight to Toronto.[22] This was the first nonstop service between India and North America.[23] Russia's decision to open its airspace after the Cold War allowed the airline to save time by flying a direct route over the Arctic.[24] Even though the 11 September attacks had precipitated a global decline in air travel, Canada 3000 was hoping that the service would help it improve its financial position.[25] Nevertheless, the company collapsed one month later.[26]
Significant growth in the Indian aviation industry led to a major increase in passenger traffic. The capacity of Terminal 1 was estimated to be 71.5 lakh (7.15 million) passengers per annum (mppa). The actual throughput for 2005/06 was an estimated 1.04 crore (10.4 million) passengers. Including the then closed down international terminal (Terminal 2), the airport had a total capacity of 1.25 crore (12.5 million) passengers per year, whereas the total passenger traffic in 2006/07 was 1.65 crore (16.5 million) passengers per year.[27] In 2008, the total passenger count at the airport reached 2.4 crore (23.97 million). To ease the traffic congestion on the existing terminals and in preparation for the 2010 Commonwealth Games,[28] a much larger Terminal 3 was constructed and inaugurated on 3 July 2010.[29] The new terminal's construction took 37 months for completion and this terminal increased the airport's total passenger capacity by 34 million.[29]
Apart from the three budget domestic airlines handled by Terminals 1 and 2, all other airlines operate their flights from Terminal 3. In June 2022, Delhi International Airport became India's first to run entirely on Hydro Power and solar energy.[30]
On 31 January 2006, the aviation minister Praful Patel announced that the empowered Group of Ministers have agreed to sell the management-rights of Delhi Airport to the DIAL consortium and the Mumbai Airport to the GVK Group.[31] On 2 May 2006, the management of Delhi and Mumbai airports were handed over to the private consortia.[32] Delhi International Airport Limited (DIAL) is a consortium of the GMR Group (54% (currently 64%)), Fraport (10%) and Malaysia Airports (10% (currently no share)),[33] and the Airports Authority of India retains a 26% stake.[34]
Nine years later, in May 2015, Malaysia Airports chose to exit from DIAL venture and sold its entire 10% stake to majority shareholder GMR Infra for $79 million. Following this GMR Group's stake at DIAL increased to 64%.[35] Earlier, GMR indicated that it was interested in buying out the 10% stake of Fraport.[36]

Delhi Airport has four near-parallel runways: runway 11R/29L, 4430mx60mm (14,530feetx200feetm), runway 11L/29R, 4400mx45mm (14,400feetx148feetm), runway 10/28, 3813mx46mm (12,510feetx151feetm), and runway 09/27, 2816mx45mm (9,239feetx148feetm). The 09/27 runway of the Delhi Airport was the airport's first-ever runway; the British constructed the 2,816 metre-long and 60 metre-wide runway in the pre-independence era and used it during World War II.[37] In addition to Chaudhary Charan Singh International Airport in Lucknow and Jaipur Airport in Jaipur, Delhi Airport is the only airport in India to have been equipped with the CAT III-B ILS, as of 2017.[38] In the winter of 2005, there were a record number of disruptions at Delhi Airport due to fog/smog. Since then some domestic airlines have trained their pilots to operate under CAT-II conditions of a minimum 350m (1,150feet) visibility. On 31 March 2006, IGI became the first Indian airport to operate two runways simultaneously following a test run involving a SpiceJet plane landing on runway 28 and a Jet Airways plane taking off from runway 27 at the same time.
The initially proposed mode involving simultaneous takeoffs in westerly flow to increase handling traffic capacity caused several near misses over the west side of the airport where the centrelines of runways 10/28 and 9/27 intersect.[39] The runway use was changed to segregate dependent mode on 25 December 2007, which was a few days after a near miss involving an Airbus A330-200 of Qatar Airways and an IndiGo A320 aircraft. The new method involved the use of runway 28 for all departures and runway 27 for all arrivals. This more streamlined model was adopted during day hours (– 2300 0600 – 2300 IST) until 24 September 2008.
On 21 August 2008, the airport inaugurated its third runway, 11R/29L, costing ₹1,000 crore[40] and 4430m (14,530feet) long. The runway has one of the world's longest paved threshold displacements of 1460m (4,790feet). This, in turn decreases the available landing length on runway 29L to 2970m (9,740feet). The reason for the long threshold displacement is due to the presence of a 263 m high Shiv statue, which is located near runway 29L.[41] [42] The runway increases the airport's capacity to handle up to 100 flights from the previous 45–60 flights per hour. The new runway was opened for commercial operations on 25 September 2008 and gradually began full round-the-clock operations by the end of October of the same year.[43]
Since 2012, all three runways are operated simultaneously to handle traffic during day hours.[44] Only runways 11R/29L and 10/28 are operated during night (2300–0600 IST) hours with single runway landing restriction during westerly traffic flow that is rotated late night (0300 IST) and reversed weekly to distribute and mitigate night time landing noise over nearby residential areas.[45]
To cater for the demand of increasing air traffic, the master plan for the construction of a fourth parallel runway next to the existing runway 11R/29L had been cleared along with the Eastern Cross Taxiways (ECT), which will have two elevated parallel taxiways linking the northern part of the airport with the southern runways. It will be elevated as it will pass over the airport approach roads. It will be long and both the taxiways will be wide, with a wide gap separating the taxiways, making it capable of handling Airbus A380 and Boeing 747 type aircraft. It will help flights reducing duration to reach the southern runways from 9–10 minutes to only two minutes, as well as reducing pollution and traffic. The fourth runway and the ECT was inaugurated on 14 July 2023.[17] [46] [47]
IGI Airport serves as a major hub or a focus destination for several Indian carriers including Air India, Alliance Air, IndiGo, SpiceJet, and Vistara. Approximately 80 airlines serve this airport. At present, there are three actively scheduled passenger terminals, as well as a cargo terminal.
Recently, Delhi Airport operator DIAL has introduced an e-boarding facility for passengers at all the three terminals of the airport, by which all boarding gates will have contactless e-boarding gates with boarding card scanners, which will allow passengers to flash their physical or e-boarding cards to verify flight details in order to proceed for security checks.[48]
Terminal 3 is an integrated terminal used for both international and domestic flights. The Indian carriers operating international flights are Air India, IndiGo, SpiceJet, and Vistara.
As far as domestic operations are concerned, Terminal 3 is used by Air India, Air India Express, Vistara, and select flights of SpiceJet and IndiGo.
Select flights of IndiGo use Terminal 2 for their domestic operations.
Terminal 1 is currently used by the low cost domestic carriers, such as SpiceJet and IndiGo. In 2022, Terminal 1D was fully expanded with an arrivals hall, with the goal of enhancing its annual passenger handling capacity from the previous 1.8 crore (18 million) to 3 crore (30 million).[49] [50]
On the morning of 28 June 2024, the canopy over the departures entrance collapsed after heavy rain in the city, killing one person and injuring 8 others. Flights from Terminal 1 have been indefinitely suspended, with 26 flights cancelled until it was decided to temporary assign them to Terminals 2 and 3 later that day.[51] [52]
Terminal 1A
Terminal 1A was built in the late 1980s to cater to Indian Airlines (now absorbed into Air India). It had to be refurbished after a fire gutted the interiors and DIAL significantly upgraded the terminal. It was used by Air India for its Airbus operations until it shifted to the new Terminal 3 on 11 November 2010.[53] This terminal is now closed and is expected to be torn down on the completion of newer terminals.
Terminal 1B
Terminal 1B was also built in the late 1980s and was used only for domestic departures. Upon the opening of the new domestic departures Terminal 1D in 2009, Terminal 1B got closed and is also expected to be torn down on the completion of newer terminals.
Terminal 1C
Terminal 1C was also built in the late 1980s and was used only for domestic arrivals. The terminal has been upgraded with a newly expanded greeting area and a larger luggage reclaim area with eight belts. Terminal 1C was shut down, torn, and rebuilt into a brand new domestic arrivals hall on 24 February 2022.
Terminal 1D
Terminal 1D is the newly built domestic departures terminal with a total floor space of 53000m2 and has a capacity to handle 1.5 crore (15 million) passengers per year.[54] Terminal 1D commenced operations on 19 April 2009.[55] It has 72 Common Use Terminal Equipment (CUTE) enabled check-in counters, 16 self check-in counters, and 16 security channels.
Terminal 2 was opened on 1 May 1986, at a cost of 95 crores[5] and was used for international flights until July 2010 when operations shifted to Terminal 3. After this, the terminal remained operational for only three months per year catering to Hajj flights.[56] In 2017, after revamping Terminal 2 at a cost of 100 crores,[56] DIAL shifted all operations of GoAir and select operations of IndiGo to that terminal in order to continue expansion work of Terminal 1.[57] [58]
Designed by HOK working in consultation with Mott MacDonald,[59] Terminal 3 is a two-tier building spread over an area of 54 lakh (5.4 million) square feet (approx 502,000 square metre) making it the world's 15th largest terminal in the world, with the lower floor being the arrivals area, and the upper floor being a departures area. This terminal has 168 check-in counters, 78 aerobridges at 48 contact stands, 54 parking bays, 95 immigration counters, 18 X-ray screening areas, shorter waiting times, duty-free shops, and other features.The international flights leave from gates 1-26 (gates 2, 4, 6 are bus gates) and the domestic flights leave from gates 27-62 (gates 42, 44 are bus gates)[60] [61] This new terminal was timed to be completed for the 2010 Commonwealth Games, which was held in Delhi and is connected to Delhi by an eight-lane Delhi–Gurgaon Expressway and the Delhi Metro through its Airport Express (Orange Line). The terminal was officially inaugurated on 3 July 2010. All international airlines shifted their operations to the new terminal in late July 2010 and all full service domestic carriers in November 2010. The arrival area is equipped with 14 baggage carousels. Terminal 3 has India's first automated parking management and guidance system in a multi-level car park, which comprises seven levels and a capacity of 4,300 cars. Terminal 3 forms the first phase of the airport expansion which tentatively includes the construction of additional passenger and cargo terminals (Terminal 4, 5, and 6).
Domestic full-service airlines Air India and Vistara operate from Terminal 3.[62] AIX Connect, although a low cost airline, also operates its domestic flights from this terminal. Some flights of SpiceJet and IndiGo were also shifted to Terminal 3 temporarily for the expansion of Terminal 1.
WorldMark is an upcoming mixed-use project in the Aerocity hospitality district near Terminal 3.
India's first general aviation terminal was commissioned in this airport in September 2020. The terminal caters to support the movement and processing of passengers flying through chartered flights or private jets from the airport.[63] [64]
The air cargo complex is located at a distance of 1km (01miles) from Terminal 3. It consists of separate brownfield and greenfield cargo terminals.[65] The cargo operations at the brownfield terminal are managed by Celebi Delhi Cargo Management India Pvt. Ltd., which is a joint venture between Delhi International Airport Private Ltd (DIAL) and the Turkish company Celebi Ground Handling (CGH).[66] CGH was awarded the contract to develop, modernise, and finance the existing cargo terminal and to operate the terminal for a period of twenty-five years by DIAL in November 2009.[67] It started its operations in June 2010.[67] In addition to the existing terminal, a new greenfield terminal is being developed in phases by Delhi Cargo Service Centre (DCSC), also a joint venture between DIAL and Cargo Service Center (CSC).[67] The greenfield cargo terminal project consists of two terminals built over a plot of 48,000 square metres and 28,500 square metres, respectively. Phase 1A of the project has been completed and is fully operational.[65] Once the entire project is completed, these two new terminals will have an annual handling capacity of 12.5 lakh (1.25 million) tonnes.[67] The cargo operations of the airport received "e-Asia 2007" award in 2007 for "Implementation of e-Commerce / Electronic Data Interchange in Air Cargo Sector".[68]
IGI complex has 4 passenger terminals, one cargo terminal and a commercial aerocity. These are the Terminal-1 in the northeast corner for the domestic flights, Aerocity commercial hub in the southeast corner, co-located Terminal-2 (for domestic budget airlines) and Terminal-3 (international flights) in the southwest corner, cargo terminal between terminal-3 and aerocity.
Under the National Capital Region Transport Plan, the following international airports are being developed as an alternate to IGI:
IGI complex has 3 metro stations. Terminal-1 in the northeast corner of IGI Complex is served by the Terminal 1-IGI Airport metro station on the Magenta Line of Delhi Metro.[72]
Terminal-2 and Terminal-3 are co-located in southwest and both are served by the same IGI Airport metro station on the Orange Line (Airport Express Line), which runs from New Delhi metro station (Connects to Yellow Line and New Delhi Railway Station) to Dwarka Sector 21 metro station (connects to Blue Line, Bijwasan railway station and Dwarka ISBT Bus Terminal) and IICC - Dwarka Sector 25 metro station (India International Convention and Expo Centre, will be further extended to Gurgaon), with trains running every 10 minutes.[73] [74] Dwarka Sector 21 metro station, west of IGI, is the metro interchange of Orange and Blue Line. Kirti Nagar to Bamnoli Metrolite, proposed light metro, will interchange at IICC - Dwarka Sector 25 metro station for the connectivity to airport.[75] Bamnoli will also be connected further south to Rapid Metro Gurgaon (at Rezang La Chowk in Palam Vihar) via existing IICC - Dwarka Sector 25 metro station (India International Convention and Expo Centre).[76] East Of IGI, the line connects to Yellow Line and New Delhi Railway Station at New Delhi Station. The line also links the Pink Line at Dhaula Kuan (Walkover Bridge between Dhaula Kuan and Durgabai Deshmukh South Campus Station)
Delhi Aerocity metro station in southeast corner of IGI, between Terminal-1 and Terminals-2 and -3 metro stations, is the metro interchange of Orange and Magenta lines. Metro Phase-IV is extending Magenta Line further east from Arocity Metro to Tuglakabad, via Vasant Kunj and Mehrauli Archaeological Park, with expected completion by 2026.[75]
Bijwasan railway station, immediately to the west of IGI on "Delhi–Jaipur line", is being upgraded to the major world-class regional multimodal transport hub, construction for ₹270.83 crore project started in 2022 and will be completed in 2024.[77]
"Hisar International Airport-IGI Airport line" (HIAIGI Line) will directly connect IGI with Hisar airport. In first phase, the missing Garhi Harsaru-Farukhnagar–Jhajjar rail link will be constructed. In the second phase, a short Hisar Airport rail line spur from the Jakhal–Hisar line to Hisar airport will be constructed.[70]
"Haryana Orbital Rail Corridor" (HORC) connects to the Delhi–Jaipur line at Patli railway station few kilometres south of Bijwasan. HORC will also provide direct rail connectivity to the Noida Airport via Palwal-Jewar rail spur.
Other smaller station near IGI on Delhi–Jaipur line is the Palam railway station, located north of Bijwasan station and northeast of IGI 4.8km (03miles) and 12km (07miles) from Terminals 1 and 3 respectively. Several suburban passenger trains run regularly between these stations.[78] [79]
The airport, which lies in south Delhi near the Delhi's border with Haryana state, is connected to Delhi in north and Gurgaon in Haryana in south by two expressways both of which have 8-lane, the older and busier 27.7 km long at-grade Delhi–Gurgaon Expressway NH 48 (part of Delhi-Jaipur National Highway) which runs through Gurgaon and newer 26.7 km long elevated Dwarka Expressway NH-248BB which passes west of Gurgaon.[80] The Dwarka Expressway begins and ends at NH-48 DELHI-Jaipur acting as a western bypass to Gurgaon, it begins immediate east of IGI airport at Shiv Murti and terminates in Haryana near Kherki Daula Toll Plaza south of Gurgaon near Western Peripheral Expressway (WPE).[81]
WPE in turn connects, listed from west to east, IGI to Delhi–Ambala–Amritsar NH 1, Delhi–Amritsar–Katra Expressway, NH9 Delhi-Hisar (Hisar Airport 150 km west of IGI), Delhi–Jaipur NH-48, Gurgaon–Sohna Elevated Expressway, Delhi–Mumbai Expressway, Faridabad–Noida–Ghaziabad Expressway (FNG), Palwal-Jewar Airport Expressway, Eastern Peripheral Expressway (EPE), etc.
Urban Extension Road-II, 75.7 km-long 6-lanes expressway, connects the IGI airport to south, southwest and western suburbs of Delhi as well as to the Delhi-Hisar NH-9.[82]
As of 2024, two Inter-State Bus Terminals (ISBT) for long-distance buses are being constructed for the IGI.
Air conditioned low-floor buses operated by Delhi Transport Corporation (DTC) regularly run between the airport and the city.
Metered taxis are also available from Terminals 1 and 3 to all areas of Delhi.[86]
In 2010, IGIA was conferred the fourth best airport award in the world in the 1.5–2.5 crore (15–25 million) category, and Most Improved Airport in the Indo-Pacific Region by Airports Council International.[87] The airport was rated as the Best Airport in the world in the 2.5–4 crore (25–40 million) passengers category in 2015, by Airports Council International.[88] [89] It was awarded The Best Airport in Central Asia and Best Airport Staff in Central Asia at the Skytrax World Airport Awards 2015.[90] It also stood first in the new rankings for 2015 Airport Service Quality (ASQ) Awards conducted by Airports Council International.[91]
The airport, along with Mumbai Airport, was adjudged as the "World's Best Airport" at the Airport Service Quality Awards 2017, in the highest category of airports handling more than 4 crore (40 million) passengers annually.[92] The airport was awarded the "best airport" in Asia-Pacific in 2020 (over 4 crore (40 million) passengers per annum) by the Airports Council International.[93] In 2023, the airport was awarded as the Cleanest Airport in the Asia-Pacific Region and also stood first again in the rankings for 2022 Airport Service Quality (ASQ) Awards in the category of over 4 crore (40 million) passengers per annum, conducted by Airports Council International.[94]
The newer domestic arrivals and departures terminals 1C and 1D, respectively, will be connected and expanded into a singular domestic terminal which will be known as simply, Terminal 1.
Terminals 4, 5, and 6 will be built at a later stages which will be triggered by growth in passenger traffic. Once completed, all international flights will move to these three new terminals. Terminal 3 will then be solely used for handling domestic air traffic. A new cargo handling building is also planned. According to Delhi International Airport Limited (DIAL), these new terminals will increase the airport's annual passenger volume capacity to 10 crore (100 million).[95]
DIAL submitted a plan in 2016 to the then aviation secretary R N Choubey regarding the expansion of the airport with a new fourth runway and Terminal 4 in a phased manner. The Master Plan of Airport in 2016 was then reviewed and updated by DIAL in consultation with the Airports Authority of India.[96] The terminal construction will start after the fourth runway is completed and Terminal 1 is expanded.
