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. This change ended the airport's 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 Simpson Bay 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 airport's 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. Facilities Runway The airport has a single runway numbered 10/28, measuring 7,546 ft x 148 ft (2,300 m x
