[6][7] Located mostly in Racha Thewa subdistrict, Bang Phli district, Samut Prakan province, it covers an area of 3,240 ha (32.4 km2; 8,000 acres), making it one of the biggest international airports in Southeast Asia and a regional hub for aviation.

In Thailand, government proclamations and national museums insist that Suvarnabhumi was somewhere on the coast of the central plains, near the ancient city of U Thong, which might be the origin of the Indianised Dvaravati culture.

Motorway 7 connects the airport, Bangkok, and the heavily industrial eastern seaboard of Thailand, where most export manufacturing takes place.

[17] The need for the new airport was recognized in 1973 when 8,000 acres (3,200 ha) of land was purchased 40 km (25 mi) east of Bangkok.

[citation needed] On 14 October 1973, student-led protests led to the overthrow of the military government of Prime Minister Thanom Kittikachorn and the project was shelved.

On 23 September 2005, the Thai airport authority held a ceremony where 99 Buddhist monks chanted to appease the spirits.

Two Thai Airways aircraft, a Boeing 747-400 and an Airbus A300-600, simultaneously departed the airport at 09:19 to Singapore and Hong Kong respectively.

[25][26] Subsequent problems included the failure of the cargo computer system, and the departure boards displaying the wrong information, resulting in confused passengers (especially as unlike Don Mueang, there were no "final calls" issued).

[27] Months after its opening, issues of 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 made.

[33] On 27 January 2007, the Department of Civil Aviation declined to renew the airport's safety certificate, which had expired the previous day.

"The constant resurfacing of the tarmac, taxiways and apron area with asphalt is an unacceptable patchwork solution.

[35] In January 2007, Thai Airways announced a plan to move some of its domestic operations back to Don Mueang International Airport due to overcrowding.

Three days later, the Ministry of Transport recommended temporarily reopening Don Mueang while repair work on the runways at Suvarnabhumi proceeded.

Thai AirAsia said it would not move unless it could shift both its international and domestic operations, prompting them to stay at Suvarnabhumi for the time being.

One-Two-GO was integrated into Orient Thai Airlines in July 2010, but continued to operate from Don Mueang Airport until liquidation in 2018.

[40] Suvarnabhumi Airport's main terminal roof is designed with structural elements and bays placed in a cantilevered, wavelike form to appear to "float" over the concourse beneath.

[41] The result of Helmut Jahn's vision is a structure with performance materials serve in their total composition and in use more than in their conventional roles.

A translucent membrane with three layers was developed to mediate between the interior and exterior climate, dealing with noise and temperature transmission, while still allowing natural flow of daylight into building along with views of greenery outside.

[49][50][51] Petty thieves and confidence men, the majority of them illegal taxi drivers or tour guides, are known to prey on tourists in the arrival hall.

They belong to politically well connected criminal groups: Kamnan Samruay, Boonruang Srisang, Sak Pakphanang, the Pattaya Mafia and Phuyai Daeng.

(The head of the Pirap gang is supposedly related to an Airports of Thailand executive, while the Phuyai Daeng has ties to influential civil servants in Samut Prakan.

[58]) On 1 October 2010, two hundred armed men occupied the airport's parking area for an hour, blocking the building's entrances and seizing ticket booths to collect fares from motorists.

Additionally, flights are able to park at remote locations on the ramp, from which airport buses transport passengers to and from the terminal.

Above the underground rail link station and in front of the passenger terminal building is a 600-room hotel operated by Accor under the Novotel brand.

Phase Two would raise the airport's capacity to 65 million passengers a year and would be undertaken in parallel with the construction of a new domestic terminal.

[66] In March 2024 Prime Minister Srettha Thavisin said the third runway would open in October 2024, with a long-term target capacity of 150 million passengers.

their hubs to DMK in October 2012 The 30 billion baht Suvarnabhumi Airport Link was opened on 23 August 2010,[256] after multiple delays.

The Airport Rail Link (ARL) is operated by SRTET, a subsidiary company of the State Railway of Thailand.

A shuttle bus service linking the airport with Hua Takhe railway station is provided by BMTA.

The Sky Lane is a controlled-access, one-direction, two-lane track built only for cycling, so the riders can be ensured that they will not be bothered by any vehicle.
