Princess Juliana International Airport (IATA: SXM, ICAO: TNCM) is the main airport on the Caribbean island of Saint Martin/Sint Maarten. The airport is located on the Dutch side of the island, in the country of Sint Maarten. In 2015, the airport handled 1,829,543 passengers and around 60,000 aircraft movements. The airport serves as a hub for Windward Islands Airways and is the major gateway for the smaller Leeward Islands, including Anguilla, Saba, St. Barthélemy and St. Eustatius. It is named after Queen Juliana, who landed here while still only heir presumptive in 1944, the year after the airport opened. The airport has very low-altitude flyover landing approaches, owing to one end of its runway being extremely close to the shore and Maho Beach. There is also an airport on the French side of the island, in the French Collectivity of Saint Martin, called Aéroport de Grand Case or L'Espérance Airport.
The airport began as a US military airstrip in 1942 during World War II. The following year, first commercial flight landed on December 3, 1943. 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 program 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, 27,000 square metres (290,000 sq ft), terminal, capable of handling 2.5 million passengers per year, and the construction of a Runway End Safety Area (RESA) of 150 metres (490 ft), including a 60 metres (200 ft) 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 terminal has 4 jetways for large aircraft like 747s. If traffic develops as forecast, Phase III of the masterplan will be executed, consisting of an extension of the new terminal building and the construction of a full parallel taxiway system.
In 1994, the Kingdom of the Netherlands and France signed the Franco-Dutch Treaty on Saint Martin Border Controls, which allows for joint Franco-Dutch border controls on so-called "risk flights". After some delay, the treaty was ratified in November 2006 in the Netherlands, and subsequently entered into force on 1 August 2007.
In July 2016, KLM announced that, starting in October, it would serve the airport with direct flights from Amsterdam instead of the triangle route via Curaçao. The previous triangle route used a Boeing 747. The new direct route would use an Airbus A330. Due to this change, the airport lost its last regularly scheduled Boeing 747 service. The 747 made its last appearance at the airport on 28 October 2016. Maho Beach was almost completely covered with tourists and plane-spotters who came to witness the last landing and departure of the aircraft. In September 2017 it did make a brief return in the aftermath of Hurricane Irma, operating some relief flights. At the same time KLM announced the return of the triangle route via Curaçao, this time however operated by an Airbus A330. In September 2018, KLM officials confirmed that they hope to resume direct flights between Amsterdam and St. Maarten by November 2019.
On 6 September 2017, the airport suffered significant damage when Hurricane Irma struck the island as a Category 5 hurricane. Video from a Dutch military helicopter showed the roof had been blown off the terminal, the jetways were damaged, and there was a significant amount of sand (blown through the fences from Maho Beach) and flooding on the runway. The airport reopened on 10 October 2017 using temporary facilities while repair work commenced. Pavilions were in use during reconstruction of the main terminal. It was hoped to move the airports departure and arrival operations into the ground floor of the main terminal building by November. In December 2018, temporary arrival and departure facilities opened within the first level of the terminal building.  The entire upper floor of the terminal and the four jet-bridges remain temporarily out of commission.
The airport has a single runway numbered 10/28, measuring 7,546 ft x 148 ft (2,300 m x 45 m). It was renumbered from 09/27 in late 2008.
Arriving aircraft approach the island on the last section of the final approach for Runway 10, following a 3° glide slope flying low over the famous Maho Beach. The proximity of Maho Beach to the runway has made the airport one of the world's favorite places among planespotters despite the dangers. In 2017 a New Zealand woman died from injuries sustained by jet blast from a departing aircraft. Tourists have been often criticised for dangerous behavior on the beach.
The main apron measures 72,500 square metres (780,000 sq ft) with another 5,000 square metres (54,000 sq ft) on Eastern apron. For freight handling a dedicated apron of 7,000 square metres (75,000 sq ft) is available.
Designed to handle some 2.5 million passengers annually, the new four-story terminal building offered (at least until the arrival of Hurricane Irma) 30,500 square metres (328,000 sq ft) of floor space and was fully air-conditioned. Available facilities included 46 check-in desks, 10 transit desks and 13 boarding gates. There were 20 immigration booths for arriving passengers and five exit-control booths for departing passengers. The building also featured 40 shops and food & beverage unitssome unique to St. Maartenpromoted under the retail theme 'So Much More'.
Since official opening of the new control tower, PJIA air traffic controllers have two radar systems at their disposal with ranges of 50 nautical miles (93 km) and 250 nautical miles (460 km). PJIA controllers manage 4,000 square NM of airspace known as the Juliana TCA around the airport, roughly between 25 nautical miles (46 km) and 42 nautical miles (78 km) of the St Maarten VOR-DME. Besides providing approach, tower and ground control at PJIA, these controllers also provide approach control for Clayton J. Lloyd International Airport (Anguilla), L'Espérance Airport (French Saint Martin), Gustaf III Airport (St. Barths), F.D. Roosevelt Airport (St. Eustatius) and Juancho E. Yrausquin Airport (Saba).
