Nonstop flight route between Cahokia, Illinois (near St. Louis), United States and Bangkok, Thailand:

About this route:

A direct, nonstop flight between St. Louis Downtown Airport (CPS), Cahokia, Illinois (near St. Louis), United States and Suvarnabhumi Airport (NBK), Bangkok, Thailand would travel a Great Circle distance of 8,758 miles (or 14,094 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. Louis Downtown 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 St. Louis Downtown Airport and Suvarnabhumi Airport. You'll see that it will travel the same route of the red line on this map!

• The closest airport to St. Louis Downtown Airport (CPS) is Lambert–St. Louis International Airport (STL), which is located only 16 miles (27 kilometers) NW of CPS.
• Historic Hangar #2 houses the Greater Saint Louis Air & Space Museum and the airport is still home to the nation's oldest flight school, Parks College of Engineering and Aviation's Center for Aerospace Sciences, which holds CAA Flight School Certificate #1.
• The furthest airport from St. Louis Downtown Airport (CPS) is Margaret River Airport (MGV), which is located 10,998 miles (17,700 kilometers) away in Margaret River, Western Australia, Australia.
• Because of St. Louis Downtown Airport's relatively low elevation of 413 feet, planes can take off or land at St. Louis Downtown 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 closed in 1959 and reopened six years later as Bi-State Parks Airport.
• The two survivors out of the airport's original four hangars, Hangar 1 and Hangar 2, are listed on the National Register of Historic Places.

Facts about Suvarnabhumi Airport (NBK):

• The furthest airport from Suvarnabhumi Airport (NBK) is Jorge Chávez International Airport (LIM), which is nearly antipodal to Suvarnabhumi Airport (meaning Suvarnabhumi Airport is almost on the exact opposite side of the Earth from Jorge Chávez International Airport), and is located 12,252 miles (19,718 kilometers) away in Callao (near Lima), Peru.
• Fifty percent of the airport's construction cost was covered by Airports of Thailand, while the another 50% was from a friendly agreement of AOT and the Japan Bank for International Cooperation.
• 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.
• 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 January 2007, ruts were discovered in the runways at Suvarnabhumi.
• The closest airport to Suvarnabhumi Airport (NBK) is Suvarnabhumi Airport (BKK), which is located only 0 mile (0 kilometer) N of NBK.
• Planning of a second international airport for Bangkok started in the early 1960s.
• 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.
• In addition to being known as "Suvarnabhumi Airport", other names for NBK include "ท่าอากาศยานสุวรรณภูมิ" and "BKK".
• In January 2007, Thai Airways announced a plan to move some of its domestic operations back to Don Muang International Airport due to overcrowding.
• The Engineering Institute of Thailand sent a formal warning to the AoT in November 2006 about the urgent need to drain water from beneath the tarmac, and the need for immediate action.
• Suvarnabhumi Airport (NBK) has 2 runways.
