Suvarnabhumi Airport

The need for the new airport was recognized in 1973 when 8,000 acres of land was purchased 40 kilometres east of Bangkok. The site, known as Cobra Swamp, was drained and named Suvarnabhumi, meaning "realm of gold". 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.

After a series of ups and downs, the "New Bangkok International Airport" company (NBIA) was formed in 1996. Due to political and economic instabilities, notably the Asian financial crisis of 1997, construction did not begin until six years later in January 2002 by the government of Thaksin Shinawatra.

The airport was due to open in late 2005, but a series of budget overruns, construction flaws, and allegations of corruption plagued the project.

A further delay was caused by the discovery that the airport had been built over an old graveyard. Superstitious construction workers claimed to have seen ghosts there. On 23 September 2005, the Thai airports authority held a ceremony where 99 Buddhist monks chanted to appease the spirits.[15]

Full tests of the airport took place on 3 and 29 July 2006. Six airlines—Thai Airways International, Nok Air, Thai Air Asia, Bangkok Airways, PBair, and One-Two-GO—used the airport as a base for twenty domestic flights.[16][17] The first international test flights were conducted on 1 September 2006. 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. At 15:50 the same aircraft flew back and made simultaneous touchdowns on runways 19L and 19R. These test flights demonstrated the readiness of the airport to handle traffic.

On 15 September 2006, the airport started limited daily operations with Jetstar Asia Airways operating three Singapore to Bangkok flights. Bangkok Airways moved to the airport on 21 September. AirAsia and Thai AirAsia followed on 25 September and on 26 September Nok Air moved to Suvarnabhumi Airport. During this initial phase, as well as in the previous tests, the airport used the temporary IATA code NBK.

Suvarnabhumi officially opened at 03:00 on 28 September 2006, taking over all flights from Don Mueang. The first flight to arrive was a Lufthansa Cargo flight LH8442 from Mumbai at 03:05.[18] The first commercial arrival was Japan Airlines at 03:30. The first passenger arrival was Aerosvit flight VV171 from Kiev at 04:30, and the first cargo departure was Saudi Arabian Airlines flight SV-984 to Riyadh at 05:00.[19] Aerosvit also had the first passenger departure (VV172 to Kiev) around 05:30.[20]

Difficulties were reported in the first few days of the airport's operation. On the first day alone, sluggish luggage handling was common—the first passenger arrival by Aerosvit took an hour for the luggage to start coming out, and some flights did not have their luggage coming out even after four hours. Flights were delayed (Thai Airways claimed that 17 of 19 flights were delayed that day), and there were failures with the check-in system.[21][22] 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).[23]

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.[24] Expert opinions varied widely on the extent of Suvarnabhumi's problems as well as their root cause. Most airlines stated that damage to the airport was minimal.[25][26] Then Prime Minister Surayud Chulanont reopened Don Mueang for domestic flights on a voluntary basis on 16 February 2007, with 71 weekly flights moved back initially, but no international flights.[27]

In January 2007, ruts were discovered in the runways at Suvarnabhumi.[28] The east runway was scheduled to close for repairs. Expert opinions varied as to the cause of the ruts.[25] Airport authorities and airline representatives maintained that the airport was still safe and resisted suggestions that the airport should be completely closed and all flights moved back to Don Mueang.[29]

On 27 January 2007, the Department of Civil Aviation declined to renew the airport's safety certificate, which had expired the previous day. The ICAO requires that international airports hold aerodrome safety certificates, but Suvarnabhumi continued to operate because the ICAO requirement had yet to be adopted as part of Thai law.[30]

As of early 2016, tarmac problems persisted at Suvarnabhumi. Soft spots on the tarmac, taxiways, and apron area had not been permanently fixed. Aircraft were getting stuck on the soft surfaces that are the result of sub-standard materials. "The constant resurfacing of the tarmac, taxiways and apron area with asphalt is an unacceptable patchwork solution. We literally need a "concrete" solution," said Tony Tyler, IATA's director general and CEO.[31]

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. At that time, Thai Airways said it would shift most of its domestic flights back to Don Mueang while keeping flights with high international passenger connections such as Chiang Mai and Phuket at Suvarnabhumi. On 28 March 2009, Thai Airways discontinued all domestic flights from Don Mueang. Bangkok Airways and One-Two-GO Airlines had similar plans, but Bangkok Airways remained at Suvarnabhumi. 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. Nok Air and PBair were undecided, but Nok Air later relocated all flights to Don Mueang, where they operate today.[32][33] As of January 2010, only Nok Air and One-Two-GO operated domestic flights from Don Mueang Airport. PBair have ceased operations altogether. One-Two-GO was integrated into Orient Thai Airlines in July 2010, but continues to operate from Don Mueang Airport. As of 1 October 2012 Air Asia has moved all of its Bangkok operations to Don Mueang International Airport (DMK) from Suvarnabhumi Airport (BKK).[34]

Airports of Thailand found that the cost of fixing 60 identified problems at the airport would be less than one percent of the total airline cost and the problems could be fixed in up to four to five years. Dr Narupol Chaiyut, a member of a committee overseeing service problems at the new airport, estimated that 70 percent of the problems would be fixed in 2007. Twenty of the 60 problems were successfully fixed by February 2007.[35]

By mid-2015, the airport was handling more than 800 flights per day, higher than its 600-flight capacity. It has exceeded its capacity of 45 million passengers per year.[51]

Airports of Thailand (AOT) approved an investment budget for the expansion of Suvarnabhumi Airport and construction began in late 2016 and finish in 2021 or early 2022.[52][53] The plan was to strengthen Suvarnabhumi Airport's position as a regional aviation hub. 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.[54] The new domestic terminal will be intended to accommodate more than 30 million passengers annually.[53]

The two expansion projects are part of the overall airport enlargement that would see Suvarnabhumi raise its annual passenger handling capacity to 125 million passengers, 90 million international and 35 million domestic passengers by 2024 at an estimated cost of 163 billion baht (US$5.25 billion/€3.62 billion). The expansion includes the construction of one additional runway, subsequent enlargement of domestic and international terminals, and improvements to parking bays, car parks, and other airport infrastructure.[55]

An expansion plan to increase the passenger capacity of the airport to 65 million by building an additional satellite passenger concourse linked to the current main terminal via an underground automated people mover (APM) system was set to be voted on by the AOT board during a 17 May 2012 meeting. If the plan gains endorsement by the board it will be able to proceed to appointing a project management consultant (PMC) which will bring it one step closer to commencing construction on the much needed expansion. If all goes to plan the expansion is set to be completed in 2018. The expansion also includes a plan to expand the airport parking garage as well as the expansion of the eastern end of the main passenger terminal by 135 meters along with the construction of a new airline office building. The expansion does include plans to construct a third runway of 3,700 meters. According to the Bangkok Post, the new satellite terminal will have a total of 28 gates, with eight for the Airbus A380 super jumbo jet.[56]

The new passenger terminal will be used only by Bangkok Airways and flag carrier Thai Airways (and its budget subsidiary Thai Smile). Upon completion of the satellite terminal, other Star Alliance members will be given the check-in concourse of Thai Airways.[57]

Suvarnabhumi accounted for the largest share of air traffic at Thailand's airports in 2015, handling 52.9 million passengers, up by nearly 14 percent from the previous year despite its passenger capacity of only 45 million a year. International passengers passing through Suvarnabhumi grew 15.9 percent to 44.2 million, while domestic volume edged up 4.87 percent to 8.68 million. Aircraft movements showed a 9.5 percent increase to 317,066, consisting of 247,584 international (up 11 percent) and 69,482 domestic (up 4.4 percent).[99]

Bangkok Suvarnabhumi Airport passenger totals (millions)

The 30 billion baht Suvarnabhumi Airport Link was opened on 23 August 2010,[102] after multiple delays. The Airport Rail Link (ARL) is operated by SRTET, a subsidiary company of the State Railway of Thailand. The standard gauge line is 28.6 kilometres (17.8 mi) long and is elevated for most of its length, running mostly above existing regional railway lines and parallel to Motorway 7 and Si Rat Expressway. There is a short at-grade/underground segment as the line approaches the passenger terminal building of Suvarnabhumi Airport.

The ARL hours of service are 06:00 to 24:00.[103] The ARL has two interchange stations, namely Phaya Thai (changing for BTS Green Line services) and Makkasan (linking Phetchaburi station of the MRT Blue Line). In the future, the ARL will complement the SRT Red Line commuter service, which comprises two-meter gauge, dual-track lines. The ARL may also be extended from Phaya Thai to Don Mueang via Bang Sue, given that the old Don Mueang International Airport has now been reopened for civil aviation under a dual-airport policy.

Meanwhile, SRT provides a suburban commuter train service between Lad Krabang (the nearest station to Suvarnabhumi on the East line, one station from the airport by Airport Rail Link) and the northern suburban city of Rangsit via downtown Bangkok and the old Don Mueang Airport. The train also connects with BTS and MRT at Phaya Thai and Phetchaburi stations respectively. A shuttle bus service linking the airport with Hua Takhe railway station is provided by BMTA. The train service is currently not as popular as the bus service because it requires a shuttle bus connection. The service will be stopped when the Airport Express Link is completed.

A free bus service connecting Suvarnabhumi Airport and Don Mueang Airport operates from 05.00 until midnight. Three air-conditioned city bus routes are operated by Bangkok Mass Transit Authority (BMTA) serve the airport's dedicated bus terminal. There are also direct buses between the airports operated by Airport Shuttle Bus.

The airport has five main access routes. Among these the most convenient route is via the Bangkok Chon Buri Motorway (Motorway 7). Another main airport entrance is in Samut Prakan Province via the expressway from Bang Na to Bang Pakong.

The airport has provided five entrance routes. The main route is via the motorway in the north of Bangkok, directly connecting Bangkok's downtown and Chonburi Province, the industrial and harbor city in eastern Thailand. However, another main airport entrance is in Samut Prakan Province, connecting an elevated highway in the south of Bangkok from Bang Na to Bang Pakong.
