The Centre on Wednesday said it plans to expand passenger handling capacity at the Indira Gandhi International Airport (IGIA) here to 109.3 million passenger per annum (mppa) in a phased manner.

"The updated master plan envisages expansion of passenger handling capacity at the IGIA from existing 62 mppa to 109.3 mppa in a phased manner by way of both airside and terminal side developments," Minister of State for Civil Aviation Jayant Sinha told the Rajya Sabha.

The Minister said the developmental works include expansion of Terminals 1 and 3, construction of Terminal 4, and construction of new runways in three phases from 2017 till 2034.

"The total area of IGI Airport demised to DIAL (Delhi International Airport) is 4,608.90 acres. The land available is sufficient for executing the expansion plan under the master plan 2016," Sinha said in a written reply.

"The design, project cost and other details etc. are finalised during the finalisation of the major development plan in compliance with the OMDA (Operation, Management and Development Agreement)."

The minister added that the development works under the updated plan are based on factors such as traffic triggers, optimum utilisation of capex and induction of new technologies and best industry practices to enhance passenger experience.
