The total length of the line is , of which is underground and is elevated, spanning from Buddha Jayanti Park to Mahipalpur.
The line runs at a speed of providing for a 15-minute journey from New Delhi to IGI Airport. In 2023, the operational speed of the Airport Express Line was increased to from , making it the fastest metro line in the country.
Previously operated by its concessionaire Reliance Infrastructure Ltd, who built the line and invested half of the capital expenditure (the other half was borne by DMRC), it notified DMRC on 27 June 2013 of its inability to operate the line beyond 30 June 2013. Following this, DMRC took over operations of Airport Express line from 1 July 2013, with an operations and maintenance team comprising 100 officials designated to handle the line.
History
The first tenders for line construction were awarded in September 2007. On 23 January 2008, the DMRC awarded a 30-year build-operate-transfer PPP contract to the Reliance Energy-CAF consortium. However, DMRC paid for half of the construction cost and executed tunneling and civil works.
It was built at a cost of , of which Reliance Infra paid , Reliance Infra will also pay fees on a revenue-share model
The elevated section of the Airport Express Line was built over eight busy roads that sustain heavy volume of traffic, including the Ring Road, National Highway 48, Ridge Road and Sardar Patel Marg.
Originally scheduled to open by 31 August 2010, well in time for the 2010 Commonwealth Games, the line finally opened on 23 February 2011 at 2 PM after missing four previously set deadlines. The DMRC fined Reliance Infra every day from 30 September, and every day from 31 October for repeatedly missing the deadlines. The Aerocity and Dhaula Kuan stations opened on 15 August 2011.
Services were suspended on 8 July 2012 due to a series of technical and infrastructural problems, including cracks in the girders, the iron beams that support the tracks; dislocated bearings that support the train; defective tracks and water seepage in tunnels. The Urban Development Ministry subsequently disclosed that several clips in the underground section were seriously damaged and it would take at least 5 months to rectify the problem. A joint inspection conducted by a Delhi Metro and Reliance Infrastructure team revealed that 540 bearings warranted rectification and that some girders which cracked also required to be recast.
The line reopened on 23 January 2013, operating at a reduced speed of . At the reduced speed, the time travel from New Delhi station to Terminal 3 of the Delhi Airport was around 40–50 minutes. Following inspection by the DMRC and various other experts, DMRC reinstated speeds on the line in mid-2014.
At the original speed of , the journey from New Delhi metro station to Airport takes just 20 minutes.
In 2022, the DMRC decided to increase the operating speed from to by 2023, reducing travel time from the current 20 minutes to less than 15 minutes.
On 17 September 2023, the Dwarka Sector 25 metro station opened to the public, extending the Airport Express Line westwards towards the India International Convention and Expo Centre, which was inaugurated the same day. The station is located underneath the new convention center, with entrances providing a quick connection to exhibition halls as well as an indoor arena, among other attractions at the new convention center.

Rolling stock
Eight six-car trains supplied by CAF were imported from Spain. CAF holds 5% equity in DAMEPL, a holding company Spice Commerce and Trade Pvt. Ltd. holds 65% equity and Reliance Infrastructure holds the remaining 30%. The trains on this line are of a premium standard and have in-built noise reduction features for a noise-free ride with padded fabric seats. The trains are fitted with an event recorder which can withstand high levels of temperature and impact and the wheels have flange lubrication system for less noise and better riding comfort.
Based on the consultancy by MTR, the interior design of the rolling stock is highly similar to that of Hong Kong's Airport Express line, which uses very similar trains.
Tracks To ensure safety, the tracks are fitted with RHEDA-2000 signalling technology, which theoretically allows trains to travel at up to (nearly three times the actual maximum speed of current trains). The entire route is ballast-less track, which costs 40–50% more than normal train tracks, but does not take longer to lay than traditional tracks. The rails rest on rubber pads on the concrete sleepers for less noise.
The elevated section from Buddha Jayanti Park to Mahipalpur has been built with 25 m long girders for the first time in India. The 504 girders weigh 120 tons each and were cast in Mahipalpur and transported on 35 m long trailers with 64 tyres.
