About this route:
A direct, nonstop flight between Dillon Airport (DLN), Dillon, Montana, United States and Union Island Airport (UNI), Union Island, Saint Vincent and the Grenadines would travel a Great Circle distance of 3,740 miles (or 6,019 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 Union Island 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 Union Island Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Dillon Airport (DLN):
- Dillon Airport (DLN) has 2 runways.
- The furthest airport from Dillon Airport (DLN) is Sir Gaëtan Duval Airport (RRG), which is located 10,660 miles (17,155 kilometers) away in Rodrigues Island, Mauritius.
- The closest airport to Dillon Airport (DLN) is Bert Mooney Airport (BTM), which is located 48 miles (78 kilometers) N of DLN.
- 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 Union Island Airport (UNI):
- The furthest airport from Union Island Airport (UNI) is Umbu Mehang Kunda Airport (WGP), which is nearly antipodal to Union Island Airport (meaning Union Island Airport is almost on the exact opposite side of the Earth from Umbu Mehang Kunda Airport), and is located 12,203 miles (19,639 kilometers) away in Waingapu, Sumba, East Nusa Tenggara, Indonesia.
- Because of Union Island Airport's relatively low elevation of 14 feet, planes can take off or land at Union Island Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
- The closest airport to Union Island Airport (UNI) is Canouan Airport (CIW), which is located only 8 miles (14 kilometers) NE of UNI.
- Union Island Airport (UNI) currently has only 1 runway.
