Netaji Subhash Chandra Bose International Airport

Netaji Subhas Chandra Bose International Airport (IATA code: CCU, ICAO code: VECC), locally known as Kolkata Airport and Dum Dum Airport before being renamed in 1995, is an international airport serving the Kolkata Metropolitan Area and is the aviation hub for the entire eastern and northeastern India. It is located approximately 15 kilometres (9.3 miles) from the city centre.

Opened in 1924, the airport is one of the oldest airports in India. Spread over an area of 1,641 acres (664 ha), it is the largest hub for air traffic in the eastern part of the country and one of two international airports operating in West Bengal, the other being Bagdogra.

The airport's new integrated terminal T2 is spread over 233,000 square meters (2,510,000 square meters) and can handle 25 million passengers annually, compared to the previous terminals' capacity of five million. The terminal is an L-shaped structure, containing six levels. It contains 128 check-in counters that utilise CUTE (Common User Terminal Equipment) technology and has 78 immigration counters and twelve customs counters.

Kolkata's old international and domestic terminals closed permanently when the integrated terminal opened. However, the old international terminal may be used for future hajj services and is currently under renovation, and the domestic terminal may be used by regional airlines. An earlier proposal of continuing low-cost carrier operations from the existing domestic terminal has been shelved due to the need to fully utilise the new integrated terminal's capacity, making it the first airport in India to shift even its low-cost domestic airlines to the new integrated building upon completion.

The airport handled almost 20 million passengers in the financial year 2017–18, making it the fifth-busiest airport in India in terms of passenger traffic after airports at Delhi, Mumbai, Bengaluru, and Hyderabad. It is awarded as best airport by hygiene measures in Asia-Pacific in 2020 by Airports Council International.
