Nonstop flight route between Challis, Idaho, United States and Hilo, Hawaii, United States:

About this route:

A direct, nonstop flight between Challis Airport (CHL), Challis, Idaho, United States and Hilo International Airport (ITO), Hilo, Hawaii, United States would travel a Great Circle distance of 2,894 miles (or 4,658 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 Challis Airport and Hilo 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 Challis Airport and Hilo International Airport. You'll see that it will travel the same route of the red line on this map!

• Challis Airport (CHL) currently has only 1 runway.
• Because of Challis Airport's high elevation of 5,072 feet, planes must typically fly at a faster airspeed in order to takeoff or land at CHL. Combined with a high temperature, this could make CHL a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• The closest airport to Challis Airport (CHL) is Lemhi County Airport (SMN), which is located 45 miles (72 kilometers) NNE of CHL.
• In addition to being known as "Challis Airport", another name for CHL is "LLJ".

• Sixteen months after the dedication, scheduled inter-island service began on November 11, 1929 by Inter-Island Airways, the forerunner of Hawaiian Airlines.
• Because of Hilo International Airport's relatively low elevation of 38 feet, planes can take off or land at Hilo International Airport at a lower air speed than at airports located at a higher elevation.
