The airport features a single asphalt runway bearing 09/27. It is 9,006 feet (2,745 m) in length, with turnarounds on both ends, and two exits to the main apron. A third, seldom-used exit leads to an isolated apron for use in emergencies.
A monolithic terminal serves both domestic and international flights, with a floor-area of 26,500 m². It can process 500 passengers at any given time. The terminal features 16 check-in counters with CUTE (common-user terminal equipment), 4 immigration counters that double up as emigration counters, two aero-bridges to cater to narrow-body aircraft such as Airbus A320 family and Boeing 737 family; and two baggage-claim belts. Besides an upper-level seating area for the aero-bridge gates, the terminal features a ground-level gate to reach other aircraft on the apron on foot, or via shuttle bus. The apron can simultaneously park five narrow-body aircraft. The waiting area features essential services for the passengers, besides snack stalls, a traveler's convenience store, a bookstore with a newsstand, and stores selling merchandise indigenous to Varanasi, such as Banarasi Saris; and a VIP waiting lounge.
