Spread over 2640 acres at Dumdum in Kolkata, the largest in eastern India, the newly modernised Netaji Subhas Chandra Bose International Airport is the fifth busiest international airport in India in respect of aircraft movement (after Delhi, Mumbai, Bangalore and Chennai). It has two asphalt runways, the primary one extended by 700 meters (3627×50m) and upgraded to CATIIIB, and the secondary one (2790×46m) upgraded to CATII ILS standards. Its terminal is a new and sprawling L-shaped six-level integrated terminal of over 2,510,000 sq ft inaugurated in 2013, able to handle 25 million passengers per annum. It includes check-in counters that use CUTE (Common User Terminal Equipment) technology, 78 immigration counters, 12 customs counters, passenger lounges provided by Air India and Jet Airways, 18 aerobridges, 57 remote parking bays, 2 underground two-leveled carparks and car parking facilities in landscaped area capable of handling 5000 cars.
