Nonstop flight route between Napa, California, United States and Bangkok, Thailand:

About this route:

A direct, nonstop flight between Napa County Airport (APC), Napa, California, United States and Suvarnabhumi Airport (NBK), Bangkok, Thailand would travel a Great Circle distance of 7,898 miles (or 12,710 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 Napa County Airport and Suvarnabhumi 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 Napa County Airport and Suvarnabhumi 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.
• The closest airport to Napa County Airport (APC) is Marin County Airport (NOT), which is located only 16 miles (25 kilometers) WSW of APC.
• After World War II the property was deeded to Napa County by the War Assets Administration for civil use.

• The closest airport to Suvarnabhumi Airport (NBK) is Suvarnabhumi Airport (BKK), which is located only 0 mile (0 kilometer) N of NBK.
• Further investigations found that taxilane and taxiway rutting was caused by separation of the asphalt binder from the aggregate surface due to prolonged water infiltration into the asphalt concrete base course, a phenomenon known as "stripping." The 23-centimetre thick base course is the top-most layer of the tarmac.
• In addition to being known as "Suvarnabhumi Airport", other names for NBK include "ท่าอากาศยานสุวรรณภูมิ" and "BKK".
• Months into its opening, issues such as congestion, construction quality, signage, provision of facilities, and soil subsidence continued to plague the project, prompting calls to reopen Don Mueang to allow for repairs to be done.
• Full tests of the airport took place on 3 and 29 July 2006.
• On 27 January 2007, however, the Department of Civil Aviation declined to renew the airport's safety certificate, which expired the previous day.
• The integration of structural form into overall aesthetics is a phenomenon personally described by Helmut Jahn as "archi-neering".
• A further delay was caused by the discovery that the airport had been built over an old graveyard, and superstitious construction workers claimed to have seen ghosts there.
• Because of Suvarnabhumi Airport's relatively low elevation of 5 feet, planes can take off or land at Suvarnabhumi 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 airport is located in Racha Thewa in Bang Phli, Samut Prakan, about 25 kilometres east of downtown Bangkok.
