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

About this route:

A direct, nonstop flight between Lewistown Municipal Airport (LWT), Lewistown, Montana, United States and Singapore Changi Airport (SIN), Changi, Singapore 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 Lewistown Municipal Airport and Singapore Changi 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 Lewistown Municipal Airport and Singapore Changi Airport. You'll see that it will travel the same route of the red line on this map!

• Because of Lewistown Municipal Airport's high elevation of 4,170 feet, planes must typically fly at a faster airspeed in order to takeoff or land at LWT. 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.
• The furthest airport from Lewistown Municipal Airport (LWT) is Sir Gaëtan Duval Airport (RRG), which is located 10,508 miles (16,911 kilometers) away in Rodrigues Island, Mauritius.

Facts about Singapore Changi Airport (SIN):

• 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.
• The furthest airport from Singapore Changi Airport (SIN) is Francisco de Orellana Airport (OCC), which is nearly antipodal to Singapore Changi Airport (meaning Singapore Changi Airport is almost on the exact opposite side of the Earth from Francisco de Orellana Airport), and is located 12,345 miles (19,868 kilometers) away in Coca, Ecuador.

• Concerned that the existing airport was located in an area with potential for urban growth, which would physically hem it in on all sides, the government subsequently decided in 1975 to build a new airport at the eastern tip of the main island at Changi, at the existing site of Changi Air Base, where the new airport would be easily expandable through land reclamation.
• The airport has a development policy of always building capacity ahead of demand to avoid congestion problems common in major airports and to maintain high service standards.
• The contractor was Penta-Ocean Construction, a Japanese construction firm directly involved in numerous land reclamation projects in Singapore.
• To prepare for the arrival of the Airbus A380, the airport put into place modifications works costing S$60 million, which it has planned for since the late 1990s.
• The closest airport to Singapore Changi Airport (SIN) is Paya Lebar Air Base (PLAB) (QPG), which is located only 6 miles (9 kilometers) W of SIN.
• Construction of this terminal, Terminal 3, began in 1999, at an estimated cost of about S$1.75 billion.
• The airport was one of the largest single development projects in Singapore's history.
• Singapore Changi Airport (SIN) has 3 runways.
