<P> AAI had been considering the modernisation of Mumbai airport in 1996 although the AAI board approved a modernisation proposal only in 2003 . By then, Mumbai and Delhi airports were handling 38% of the country's aircraft movement and generating one third of all revenues earned by AAI . At that time, Mumbai airport handled 13.3 million passengers, 60% of which were domestic travellers . The airport faced severe congestion for both aircraft and passengers as it was handling twice as many aircraft movements per day than it was originally designed for . The bidding process for its modernisation eventually began in May 2004 with the decision by the Empowered Group of Ministers (EGoM) was announced in January 2006 . </P> <P> The consortium of GVK Industries Ltd, Airports Company South Africa and Bidvest, won the bid to manage and operate CSIA . To accomplish this task, Mumbai International Airport Private Limited (MIAL), a Joint Venture between the consortium (74%) and the Airports Authority of India (26%) was formed . Since then, MIAL has made several improvements in the aesthetics, design and passenger conveniences at CSIA including the refurbishment of domestic terminals 1A & 1B, international terminals 2B & 2C and the opening of a brand new domestic terminal 1C and Terminal 2 . MIAL also undertook airside improvement projects such as the commissioning of new taxiways, aprons and the reconstruction of both runways . In February 2008, MIAL entered into an agreement with Air Transport IT specialist SITA that led to CSIA becoming the first airport in India to Implement Common - use self - service Kiosks and CUTE (Common Use Terminal Equipment) check - in systems . </P> <P> The airport consists of two passenger terminals: Terminal 1 at Santacruz for domestic flights and Terminal 2 at Sahar for both international and domestic flights . While both terminals use the same airside facilities, they are physically separated on the cityside, requiring a 15--20 - minute (landside) drive between them . MIAL operates coach shuttle services between the two terminals for the convenience of transit passengers . </P> <P> The airport has two intersecting runways . Both runways have been upgraded to Code F, which means they can accommodate larger aircraft like the Airbus A380 . Following a presentation in March 2011 by UK's air traffic service provider NATS on how the capacity of the airport can be increased, MIAL set a target of 48 aircraft movements an hour in an effort to reduce congestion at the airport . Both runways were operated simultaneously especially during peak hours to try and attain this target . MIAL scrapped simultaneous Cross-runway flight operations in mid-2013 after it found that single runway operations were more effective for increasing Aircraft movements per hour . Runway 14 / 32 is now used only when the main runway is unavailable due to maintenance or other reasons . The construction of new rapid exit taxiways helped in increasing flight handling capacity from 32 movements per hour to 44 in 2012 . </P>
