Nonstop flight route between Butte, Montana, United States and Hilo, Hawaii, United States:

About this route:

A direct, nonstop flight between Bert Mooney Airport (BTM), Butte, Montana, United States and Hilo International Airport (ITO), Hilo, Hawaii, United States would travel a Great Circle distance of 3,010 miles (or 4,844 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 Bert Mooney 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 Bert Mooney Airport and Hilo International Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Bert Mooney Airport's high elevation of 5,550 feet, planes must typically fly at a faster airspeed in order to takeoff or land at BTM. Combined with a high temperature, this could make BTM a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• The airport name was changed in 1972 to honor Bert Mooney, an aviator from Butte who was the first to fly mail into Yellowstone National Park in 1935.
