About this route:
A direct, nonstop flight between St. Mary's County Regional Airport (LTW), Leonardtown, Maryland, United States and Singapore Changi Airport (SIN), Changi, Singapore would travel a Great Circle distance of 9,695 miles (or 15,603 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 St. Mary's County Regional 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 St. Mary's County Regional Airport and Singapore Changi 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.
- St. Mary's County Regional Airport (LTW) currently has only 1 runway.
- In addition to being known as "St. Mary's County Regional Airport", other names for LTW include "Capt. Walter Francis Duke Regional Airport", "none" and "2W6".
Facts about Singapore Changi Airport (SIN):
- 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.
- 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)".
- Construction of this terminal, Terminal 3, began in 1999, at an estimated cost of about S$1.75 billion.

- 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.
- T4 will also have its own Ramp Control Tower to oversee and manage aircraft movements in the apron and taxiways around the terminal.

- 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.
- 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.
