Nonstop flight route between Osaka, Japan and Seattle, Washington, United States:

About this route:

A direct, nonstop flight between Osaka International Airport (OSA), Osaka, Japan and King County International Airport (BFI), Seattle, Washington, United States would travel a Great Circle distance of 4,999 miles (or 8,046 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 Osaka International Airport and King County 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 Osaka International Airport and King County International Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Osaka International Airport (OSA):

• Construction began in July 1936 on a 53 ha site.
• In addition to being known as "Osaka International Airport", other names for OSA include "Itami International Airport", "大阪国際空港", "Ōsaka Kokusai Kūkō", "ITM" and "RJOO".

• The government proposed changing Itami's status from first-class airport to second-class airport, which would saddle local governments with one-third of its operating costs.
• By the mid-1970s, the airport was subject to extensive slot restrictions, with operations limited to 200 jets and 170 propeller aircraft per day, and no takeoffs or landings allowed after 9 PM.
• Because of Osaka International Airport's relatively low elevation of 39 feet, planes can take off or land at Osaka 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.
• On the other hand, the Japanese government has historically supported Kansai at Itami's expense, and current Osaka City mayor and former Osaka Prefecture governor Toru Hashimoto has been a particularly vocal critic of the airport, arguing that the Chuo Shinkansen maglev line will make much of its domestic role irrelevant, and that its domestic functions should be transferred to Kansai in conjunction with upgraded high-speed access to Kansai from central Osaka.
• In February 1974, the Osaka District Court issued a qualified ruling in favor of the plaintiffs which limited the scope of their damages.
• Itami was renamed Osaka Airport following its return to Japanese control in March 1959.
