DIAL is a joint venture consortium of GMR Group (54%), Airports Authority of India (26%) and Fraport & Eraman Malaysia (10% each). In January 2006, the consortium was awarded the concession to operate, manage and develop the IGI Airport following an international competitive bidding process. DIAL entered in to Operations, Management and Development Agreement (OMDA) on April 4, 2006 with the AAI. The initial term of the concession is 30 years extendable by a further 30 years.

Besides upgrading the existing terminals, DIAL has already commissioned a new runway 11-29 at IGI Airport on September 25, 2008. The commercial operations has also commenced at new Domestic Terminal from 19th April, 2009.

The modern domestic terminal (Terminal 1D) features several new facilities which will improve the travel experience of domestic departure passengers flying out of Delhi. It raises domestic departure capacity of IGIA to 10 million passengers per annum and has modern 4 level in-line baggage handling system to eliminate baggage X-ray prior to check in. The new terminal also has 72 check-in counters & 14 security channels that will ensure quick processing. It is also provided by spacious security-hold area with extensive seating, passenger amenities like Lounges, F&B and retail.

In addition, the construction work on an integrated passenger terminal (Terminal 3) is underway. The first phase of the airport is designed to handle 60 million passengers per annum (mppa). This phase will be completed and fully operational before the Commonwealth Games in 2010.

This development would form just the first phase of the airport expansion. In subsequent stages, the airport will be further developed with the increase in passenger demand and more terminals and runways would be added in a modular manner to form a U shaped complex with an ultimate design capacity of 100 million passengers per annum.

• Third runway, amongst the longest in Asia, has started operations in 2008 and is capable of handling A380 sized aircraft.
• Commercial operations commenced at new Domestic Terminal from 19th April, 2009.
• State- of- the- art integrated terminal to be ready in 2010.

Terminal 3 would be a state- of- the- art complex featuring Common Use Terminal Equipment (CUTE) and an advanced 5 level in-line baggage handling system with explosive detection technology for greater efficiency and security. The check-in area would feature more than 160 check-in counters. Passengers would greatly benefit as check-in and security clearances would be faster and less obtrusive. For international passengers more than 90 desks would facilitate immigration procedures. In addition, the terminal would also feature 48 contact stands and 75 aerobridges with 9 remote stands for aircraft.

The two tier terminal building would feature the departure complex on the upper level and the arrivals on the lower level. The roof of the building will have stylized incisions to allow daylight, but will be angled to protect the interior from direct sunlight. The effect would create a calm environment and maximize the sense of volume, space and light inside. The use of natural light would reduce the dependency on artificial light during day-time.

The arrival hall will feature both standard and wide-body baggage reclaim belts, Passengers will emerge from bag reclaim into the Internal Landside Arrivals Concourse from where transit passengers would use elevators to proceed to the Departures level. 4 piers will provide access to the aircraft from the terminal.

Access to the new terminal would be via a 6 lane approach road. The Airport would also be connected via dedicated high speed Metro line connecting to the city centre.
