About this route:

A direct, nonstop flight between Helena Regional Airport (HLN), Helena, Montana, United States and Long Island MacArthur Airport (ISP), Islip, New York, United States would travel a Great Circle distance of 1,962 miles (or 3,158 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 relatively short distance between Helena Regional Airport and Long Island MacArthur Airport, the route shown on this map most likely still appears to be a straight line.
