The terminal building of the airport has a General Waiting Hall, a Departures Wing, and an Arrivals Wing. The General Waiting Hall provides ticketing desks for local transportation (coach, ferry, helicopter, hovercraft, and taxi), postal services, a travel agency office, and a restaurant; the Departures Wing contains duty free shops, lounges, and a business centre with telephone, Internet, and fax services; the Arrivals Wing has a customs hall with a money exchange window, a lost and found baggage office, and an information office. The airport grounds also contain a bank (First International Bank Ltd), an aviation security centre, a police centre, a car park, and a mosque. The government of Sierra Leone undertook a general upgrade of the terminal in 2010, in order to meet the basic standards of current international airports. The Departure Hall has been commissioned in February 2013. The Arrival Hall is still under refurbishment.
