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

About this route:

A direct, nonstop flight between Sidney-Richland Municipal Airport (SDY), Sidney, Montana, United States and Princess Juliana International Airport (SXM), Philipsburg, Sint Maarten, Kingdom of the Netherlands would travel a Great Circle distance of 3,085 miles (or 4,965 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 Sidney-Richland Municipal Airport and Princess Juliana International 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 Sidney-Richland Municipal Airport and Princess Juliana International Airport. You'll see that it will travel the same route of the red line on this map!
