Nonstop flight route between Philipsburg, Sint Maarten, Kingdom of the Netherlands and Challis, Idaho, United States:

About this route:

A direct, nonstop flight between Princess Juliana International Airport (SXM), Philipsburg, Sint Maarten, Kingdom of the Netherlands and Challis Airport (CHL), Challis, Idaho, United States would travel a Great Circle distance of 3,455 miles (or 5,560 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 Challis 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 Challis Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Princess Juliana International Airport (SXM):

• 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.
• The main apron measures 72,500 square metres with another 5,000 square metres on Eastern apron.
• 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.
