Nonstop flight route between Johannesburg, South Africa and Barter Island, Alaska, United States:

About this route:

A direct, nonstop flight between Grand Central Airport (GCJ), Johannesburg, South Africa and Barter Island LRRS Airport (BTI), Barter Island, Alaska, United States would travel a Great Circle distance of 9,368 miles (or 15,077 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 Grand Central Airport and Barter Island LRRS 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 Grand Central Airport and Barter Island LRRS Airport. You'll see that it will travel the same route of the red line on this map!

• This is a small airfield that is restricted to light aircraft only.
• Because of Grand Central Airport's high elevation of 5,327 feet, planes must typically fly at a faster airspeed in order to takeoff or land at GCJ. Combined with a high temperature, this could make GCJ a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• The closest airport to Grand Central Airport (GCJ) is O. R. Tambo International Airport (JNB), which is located only 12 miles (20 kilometers) SSE of GCJ.
• The furthest airport from Grand Central Airport (GCJ) is Hana Airport (HNM), which is located 11,992 miles (19,299 kilometers) away in Hana, Hawaii, United States.
