Suvarnabhumi Airport (ท่าอากาศยานสุวรรณภูมิ, , thâː.ʔāː.kàːt̚.sā.jāːn.sùʔ.wān.nā.phūːm; from Sanskrit स्वर्णभूमि (Svarṇabhūmi), literally 'golden land') , also known unofficially as Bangkok International Airport, is the main international airport serving Bangkok, Thailand. Located mostly in Racha Thewa, Bang Phli, Samut Prakan, it covers an area of , making it one of the biggest international airports in Southeast Asia and a regional hub for aviation. The airport is also a major Cargo Air Freight Hub (20th busiest in 2019), which has a designated Airport Free Zone, as well as road links to the Eastern Economic Corridor (EEC) on Motorway 7.
The name Suvarnabhumi is Sanskrit for "land of gold" (Devanagari:स्वर्णभूमि IAST: Svarṇabhūmi; Svarṇa is "gold", Bhūmi is 'land'; literally "golden land"). The name was chosen by the late King Bhumibol Adulyadej whose name includes Bhūmi, referring to the Buddhist golden kingdom, thought to have been to the east of the Ganges, possibly somewhere in Southeast Asia. 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. Although the claims have not been substantiated, the Thai government named the new Bangkok airport Suvarnabhumi Airport, in celebration of this tradition.
The airport is currently the main hub for Thai Airways International, Thai Smile and Bangkok Airways, as well as the operating base for Thai VietJet Air, Thai AirAsia and Thai AirAsia X. It also serves as regional gateway and connecting point for various foreign carriers connecting to Asia, Oceania, Europe and Africa.
Suvarnabhumi was officially opened for limited domestic flight service on 15 September 2006, and opened for most domestic and all international commercial flights on 28 September 2006.
The airport is on what had formerly been known as Nong Nguhao (Cobra Swamp) in Racha Thewa in Bang Phli, Samut Prakan province as well as the districts of Bang Kapi, Lat Krabang, Bang Na and Prawet in the eastern side of Bangkok, about from downtown.
