Jai Prakash Narayan Domestic Airport (IATA: PAT, ICAO: VEPT) is located 5 kilometres (2.7 NM) southwest of Patna, the capital of state of Bihar in India. It is the 23rd busiest airport in India, and the annual passenger traffic increased by 32 per cent in the 2015-16. The Airports Authority of India (AAI) has proposed to extend the terminal over an area of 11.5 acres for sustaining air operations at least till 2035. A new terminal building would be constructed and connected to the existing building via skybridge. In addition, the AAI has planned to develop a civil enclave at Bihta Air Force Station, 20 kilometres away from Patna, to cater to larger aircraft.
