Nonstop flight route between Perth, Western Australia, Australia and Salmon, Idaho, United States:

About this route:

A direct, nonstop flight between Perth Airport (PER), Perth, Western Australia, Australia and Lemhi County Airport (SMN), Salmon, Idaho, United States would travel a Great Circle distance of 9,642 miles (or 15,517 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 Perth 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 Perth Airport and Lemhi County Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Perth Airport (PER):

• It is the fourth busiest airport in Australia and services Australian and Indian Ocean destinations, as well as Johannesburg, Auckland, Dubai, Abu Dhabi, Guangzhou and Doha.
• The airport only received international status and was renamed to Perth International Airport in 1952.
• Perth Airport handled 13,664,394 passengers last year.
• Because of Perth Airport's relatively low elevation of 67 feet, planes can take off or land at Perth 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.
• Towards the mid-1950s, airline travel was still only being used by a small percentage of the population.
• Upon completion, the terminal was able to process up to five Boeing 747 aircraft per hour and accommodated a peak passenger volume of 6,000 passengers per hour.
• The move was agreed to by the government of the day, as the larger types of aircraft of the day being operated by the two airlines could simply not be handled at Maylands, notwithstanding the small grass airfield, lack of passenger facilities, and approaches being difficult due to surrounding industrial infrastructure.
• The furthest airport from Perth Airport (PER) is L.F. Wade International Airport (BDA), which is nearly antipodal to Perth Airport (meaning Perth Airport is almost on the exact opposite side of the Earth from L.F. Wade International Airport), and is located 12,389 miles (19,938 kilometers) away in Ferry Reach (near Hamilton), Bermuda.
• In 2012, the Australian Competition and Consumer Commission released a report rating the Perth Airport as the worst in Australia, as judged by airlines.

• The closest airport to Lemhi County Airport (SMN) is Challis Airport (CHL), which is located 45 miles (72 kilometers) SSW of 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 furthest airport from Lemhi County Airport (SMN) is Tôlanaro Airport (FTU), which is located 10,686 miles (17,197 kilometers) away in Tôlanaro, Madagascar.
