On 28 September 2006, Suvarnabhumi Airport (IATA: BKK; ICAO: VTBS), became Bangkok's official international airport, replacing Don Muang. Pronounced Suwannaphum (RTGS), or loosely Su-wan-na-poom, the airport is located southeast of the city center in Bang Phli district, Samut Prakan Province.

The progress of Suvarnabhumi Airport dates back to the early 1970s when a large plot of land 8,000 acres (32 km²) was bought. A student uprising in October of the same year prevented further progress with the development when the military government of Thanom Kittikachorn was subsequently overthrown. After several military coups and the Asian financial crisis of 1997, construction finally began in 2002, after five years of clearing the site. The first flights landed in September 2006, shortly after another military coup. Its two parallel runways are connected by the five concourses of the main terminal building.
