Gerald's passenger terminal was dedicated in February 2005 by Anne, Princess Royal and the facility was formally opened on 11 July 2005. It features a 600-metre runway, a restaurant, modern air traffic control technology, immigration facilities, and is the only airport in the Caribbean with a public tunnel under its runway. The total cost of construction was approximately US$18.5 million.
The completion of Gerald's Airport allowed for the resumption of regular commercial airline service to Montserrat for the first time since 1997, when W. H. Bramble Airport, which had been the island's only aviation gateway, was completely destroyed by an eruption of the nearby Soufrière Hillsvolcano. Between 1997 and 2005, Montserrat had been accessible only by helicopters or boats.
