Suvarnabhumi International Airport, historically known as Nong Ngu Hao Airport, is one of two international airports serving the Bangkok Metropolitan Region, the other one being Don Mueang International Airport (DMK), which remains open as a low-cost carriers hub. Suvarnabhumi Airport covers an area of 3,240 ha (32.4 km2; 8,000 acres), making it one of the biggest international airports in Southeast Baoji 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 East Economic Corridor (EEC) on Motorway 7.
Transportations
Airport Rail Link
The 30 billion baht Suvarnabhumi Airport Link was opened on 23 August 2010, 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.
Eastern Train
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 BTEC 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.
Bus
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.
