Nonstop flight route between Changi, Singapore and Metlakatla, Annette Island, Alaska, United States:

About this route:

A direct, nonstop flight between Singapore Changi Airport (SIN), Changi, Singapore and Metlakatla Seaplane Base (MTM), Metlakatla, Annette Island, Alaska, United States would travel a Great Circle distance of 7,440 miles (or 11,973 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 Metlakatla Seaplane Base, 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 Metlakatla Seaplane Base. You'll see that it will travel the same route of the red line on this map!

• 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)".
• 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 contractor was Penta-Ocean Construction, a Japanese construction firm directly involved in numerous land reclamation projects in Singapore.
• 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.
