The two story terminal occupies 70,000 square feet of area and has replaced the circa 1950-built structure. US-based architectural design firm Stantec Consulting designed the new terminal inspired by the roll of the Niagara rapids, and is based on the theme of Flow – in terms of water, air and passengers. Walter S Johnson Building Company from New York was responsible for the construction of the terminal.

The expanded premises will provide for additional charter and scheduled flights, and help boost tourism in the area. The second story of the terminal has been provided to facilitate jet bridges. Security and processing operations will take full advantage of new technologies to make the airport efficient and user-friendly for passengers.

Two-gate facility at the airport will provide for efficient, customer-friendly passenger processing, a two-level layout for jet bridge boarding, food/beverage concessions, fully functional TSA inspection facilities, in-line baggage screening, eight stationary ticket counter stations, car rental, and a multi-model Metro transit center. Other improvements include access roads, a circulatory road, walkways and parking.

The terminal will provide the operational capability to simultaneously process international and domestic flights, and fully accommodate 747-400 and 757-300 aircraft. Its split-level holdrooms feature seating for 280 people and the design provides for additional seating if needed.

The new airport will also include a 10,825 feet runway capable of handling heavier aircraft.
