Nonstop flight route between Dillon, Montana, United States and Perth, Western Australia, Australia:

About this route:

A direct, nonstop flight between Dillon Airport (DLN), Dillon, Montana, United States and Perth Airport (PER), Perth, Western Australia, Australia would travel a Great Circle distance of 9,706 miles (or 15,621 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 Dillon Airport and Perth 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 Dillon Airport and Perth Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Dillon Airport's high elevation of 5,241 feet, planes must typically fly at a faster airspeed in order to takeoff or land at DLN. Combined with a high temperature, this could make DLN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.

Facts about Perth Airport (PER):

• The Guildford Aerodrome as it was then known was at best only a basic airfield.
• Perth Airport (PER) has 2 runways.
• The closest airport to Perth Airport (PER) is Jandakot Airport (JAD), which is located only 12 miles (19 kilometers) SSW of PER.
