About this route:
A direct, nonstop flight between Washington Dulles International Airport (IAD), Washington, D.C. / Virginia, United States and Naha Airport (OKA), Okinawa, Japan would travel a Great Circle distance of 7,653 miles (or 12,316 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 Washington Dulles International Airport and Naha 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 Washington Dulles International Airport and Naha Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Washington Dulles International Airport (IAD):
- The main terminal was recognized by the American Institute of Architects in 1966 for its design concept.
- Because of Washington Dulles International Airport's relatively low elevation of 313 feet, planes can take off or land at Washington Dulles 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.
- The furthest airport from Washington Dulles International Airport (IAD) is Margaret River Airport (MGV), which is located 11,659 miles (18,763 kilometers) away in Margaret River, Western Australia, Australia.
- A new train system, dubbed AeroTrain and developed by Mitsubishi, began in 2010 to transport passengers between the concourses and the main terminal.
- By the 1980s, the original design, which had mobile lounges meet each plane, was no longer well-suited to Dulles' role as a hub airport.
- The closest airport to Washington Dulles International Airport (IAD) is Leesburg Executive Airport (JYO), which is located only 11 miles (17 kilometers) NNW of IAD.

- Congested Naha Airport served 14,495,054 passengers in FY2006, roughly similar numbers in 2012.
- The basic and detailed design engineering works in addition to the later construction management phase of the main passenger terminal were awarded in the 1990s in part to the Japan Branch of the American design-build engineering company, The Austin Company, which joined Japanese firms in a joint venture design consortium.
- The furthest airport from Naha Airport (OKA) is Paulo Abdala Airport (FBE), which is nearly antipodal to Naha Airport (meaning Naha Airport is almost on the exact opposite side of the Earth from Paulo Abdala Airport), and is located 12,392 miles (19,943 kilometers) away in Francisco Beltrao, Paraná, Brazil.
