Nonstop flight route between Changi, Singapore and Portland, Oregon, United States:

About this route:

A direct, nonstop flight between Singapore Changi Airport (SIN), Changi, Singapore and Portland International Airport (PDX), Portland, Oregon, United States would travel a Great Circle distance of 8,128 miles (or 13,081 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 Portland International 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 Portland International Airport. You'll see that it will travel the same route of the red line on this map!

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.
• 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.
• On 7 March 2012, Minister of State for Transport Josephine Teo announced in Parliament that a new multi-storey complex at the current Terminal 1 carpark will be built.

• The furthest airport from Portland International Airport (PDX) is Tôlanaro Airport (FTU), which is located 10,903 miles (17,546 kilometers) away in Tôlanaro, Madagascar.
• Because of Portland International Airport's relatively low elevation of 30 feet, planes can take off or land at Portland International 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.
• Plans made in 1968 to add a third runway by means of filling in parts of the Columbia River were met with vocal public opposition and scrapped.
