Integrated Terminal T2
Kolkata’s 230,000 m² integrated passenger building opened in 2013 and is equipped to serve 26 million passengers a year. T2 contains distinct domestic and international portions; it is one roof with two processing paths.
India’s AIP lists customs and immigration H24. The official layout identifies a separate international portion within T2 for that processing.
Jai Hind Bimanbandar station is physically connected to NSCBI Airport by subway. Official railway releases confirm Yellow Line passenger service between the airport and Noapara.
Domestic and international processing share T2 but occupy separate portions. No official connection procedure was accessible, so follow the airline’s instructions for a through journey.
