About this route:
A direct, nonstop flight between Benin Airport (BNI), Benin City, Nigeria and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 7,289 miles (or 11,731 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 Benin Airport and Lemhi County 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 Benin Airport and Lemhi County Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Benin Airport (BNI):
- Benin Airport handled 308,741 passengers last year.
- Because of Benin Airport's relatively low elevation of 258 feet, planes can take off or land at Benin 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 Benin Airport (BNI) is Akure Airport (AKR), which is located 67 miles (109 kilometers) NNW of BNI.
- The furthest airport from Benin Airport (BNI) is Canton Island Airport (CIS), which is nearly antipodal to Benin Airport (meaning Benin Airport is almost on the exact opposite side of the Earth from Canton Island Airport), and is located 12,129 miles (19,520 kilometers) away in Canton Island, Kiribati.
- Benin Airport (BNI) currently has only 1 runway.
Facts about Lemhi County Airport (SMN):

- Lemhi County Airport (SMN) currently has only 1 runway.
- Because of Lemhi County Airport's high elevation of 4,043 feet, planes must typically fly at a faster airspeed in order to takeoff or land at SMN. Combined with a high temperature, this could make SMN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
- The closest airport to Lemhi County Airport (SMN) is Challis Airport (CHL), which is located 45 miles (72 kilometers) SSW of SMN.
