Nonstop flight route between Port Heiden, Alaska, United States and Asmara, Eritrea:

About this route:

A direct, nonstop flight between Port Heiden Airport (PTH), Port Heiden, Alaska, United States and Asmara International Airport (ASM), Asmara, Eritrea would travel a Great Circle distance of 7,343 miles (or 11,818 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 Port Heiden Airport and Asmara 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 Port Heiden Airport and Asmara International Airport. You'll see that it will travel the same route of the red line on this map!

This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.

Combined with a high temperature, this could make ASM a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
