Princess Juliana International Airport is the main airport on the Caribbean island of Saint Martin. The airport is located on the Dutch side of the island, in the country of Sint Maarten, close to the shore of Simpson Bay Lagoon. In 2015, the airport handled 1,829,543 passengers and around 60,000 aircraft movements. The airport serves as a hub for Winair and is the major gateway for the smaller Leeward Islands, including Anguilla, Saba, Saint Barthélemy and Sint Eustatius. It is named after Queen Juliana of the Netherlands, who landed there while she was heir presumptive in 1944, the year after the airport opened. The airport has very low-altitude flyover landing approaches because one end of its runway is extremely close to the shore and Maho Beach. While Princess Juliana International is the primary aviation gateway to the island, there is also a smaller public-use airport on the French side, in the French Collectivity of Saint Martin, called Grand Case-Espérance Airport. History The airport began as a US military airstrip in 1942 during World War II. The following year, first commercial flight landed on 3 December 1943. The future Queen Juliana visited the island using the airport in 1944. Eventually, the airport was named after her. In 1964 the airport was remodeled and relocated, with a new terminal building and control tower. The facilities were upgraded in 1985 and 2001. Because of increased passenger traffic and the expected growth of passenger traffic in the near future, Princess Juliana International Airport is being heavily modernized following a three-phased masterplan, commissioned in 1997. Phase I was a short-term programme in order to upgrade existing facilities and improve the level of service at various points. This included widening, strengthening and renovating the runway, increasing the bearing capacity of the taxiways, construction of a new apron and an upgrade of the (old) terminal. Phase I was completed in 2001. Phase II included the construction of a radar facility and a new air traffic control tower, the construction of a new and more modern, , terminal, capable of handling 2.5 million passengers per year, and the construction of a Runway End Safety Area (RESA) of , including a overrun, on both ends of its runway, to comply with ICAO rules. The new air traffic control tower and the radar station commenced operations on 29 March 2004, while the new terminal opened in late October 2006. The
