Nonstop flight route between Philipsburg, Sint Maarten, Kingdom of the Netherlands and Xining, Qinghai, China:

About this route:

A direct, nonstop flight between Princess Juliana International Airport (SXM), Philipsburg, Sint Maarten, Kingdom of the Netherlands and Xining Caojiabao Airport (XNN), Xining, Qinghai, China would travel a Great Circle distance of 8,544 miles (or 13,750 kilometers).

A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the large distance between Princess Juliana International Airport and Xining Caojiabao Airport, the route shown on this map most likely appears curved because of this reason.

Try it at home! Get a globe and tightly lay a string between Princess Juliana International Airport and Xining Caojiabao Airport. You'll see that it will travel the same route of the red line on this map!

• Princess Juliana International Airport (SXM) currently has only 1 runway.
• 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, terminal, capable of handling 2.5 million passengers per year, and the construction of a Runway End Safety Area of 150 metres, including a 60 metres overrun, on both ends of its runway, to comply with ICAO rules.
• Because of Princess Juliana International Airport's relatively low elevation of 14 feet, planes can take off or land at Princess Juliana International Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
