Nonstop flight route between Sand Point, Alaska, United States and San Juan, Puerto Rico:

About this route:

A direct, nonstop flight between Sand Point Airport (SDP), Sand Point, Alaska, United States and Fernando Luis Ribas Dominicci Airport (SIG), San Juan, Puerto Rico would travel a Great Circle distance of 5,346 miles (or 8,603 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 Sand Point Airport and Fernando Luis Ribas Dominicci 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 Sand Point Airport and Fernando Luis Ribas Dominicci Airport. You'll see that it will travel the same route of the red line on this map!
