Nonstop flight route between Changi, Singapore and Lewistown, Montana, United States:

About this route:

A direct, nonstop flight between Singapore Changi Airport (SIN), Changi, Singapore and Lewistown Municipal Airport (LWT), Lewistown, Montana, United States would travel a Great Circle distance of 8,528 miles (or 13,725 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 Singapore Changi Airport and Lewistown Municipal 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 Singapore Changi Airport and Lewistown Municipal Airport. You'll see that it will travel the same route of the red line on this map!

• A new parallel runway 02R/20L was built 1.8 km to the east of 02C/20C, currently used only by Republic of Singapore Air Force aircraft as part of Changi Airbase.
• Because of Singapore Changi Airport's relatively low elevation of 22 feet, planes can take off or land at Singapore Changi 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.
• Singapore Changi Airport (SIN) has 3 runways.
• Recently Changi Airport has also announced plans to reduce consumption of electricity and use recycled water at its terminal buildings over the next three years, as part of its contribution towards environmental sustainability.
• Singapore's International Airport at Paya Lebar, Singapore's third main civilian airport after Seletar Airport and Kallang Airport opened in 1955 with a single runway and a small passenger terminal.
• The airport was one of the largest single development projects in Singapore's history.
• In addition to being known as "Singapore Changi Airport", other names for SIN include "Lapangan Terbang Antarabangsa Changi Singapura", "新加坡樟宜机场(Xīnjiāpō Zhāngyí Jīchǎng)" and "சிங்கப்பூர் சாங்கி விமானநிலையம் (Ciṅkappūr Cāṅki Vimana Nilaiyam)".

Combined with a high temperature, this could make LWT a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
