Bangkok has two international airports: Suvarnabhumi Airport (BKK), pronounced "soo-wan-na-poom", and Don Muang Airport (DMK). Suvarnabhumi is the larger of the two and Thailand's busiest airport, and it sits in Racha Thewa, in the Bang Phli district of Samut Prakan. It is the primary hub for Thai Airways International and a hub and operating base for Bangkok Airways.
Some domestic flights use Suvarnabhumi and some use Don Muang, because both of Bangkok's airports handle them and which airport a flight uses depends on the airline.
Thai Airways International has its primary hub here and Bangkok Airways runs a hub and operating base here, so their domestic flights work mainly from Suvarnabhumi, while most low-cost carriers currently work from Don Muang.
The check that settles it is the airport code on your booking: BKK is Suvarnabhumi and DMK is Don Muang. Which airport an airline uses can change, so read the code rather than assuming from past trips.
Two destinations show in this site's route data as served from Suvarnabhumi and not from Don Muang, both of them Bangkok Airways destinations: Sukhothai Airport and Trat Airport.
Suvarnabhumi has one main terminal and one satellite terminal. The main terminal holds seven concourses, A to G, and domestic and international departures sit in the same building in separate sections.
SAT-1 handles international departures, so a domestic flight will not use it. It is a separate building about a kilometre from the main terminal, reached by an underground automated people mover that takes about three minutes.
SAT-1 opened partially in September 2023 and fully from early 2024. The Suvarnabhumi site of Airports of Thailand (AOT) gives the terminal's size as about 251,400 square metres over four storeys above ground and two below, with 28 contact gates.
That people mover adds an underground train ride to some international departures, which is time to allow for and which did not exist before September 2023.
The airport now has three runways. The third opened on 1 November 2024, 4,000 metres by 60 metres, parallel to the first runway on the western side, and it was inaugurated alongside SAT-1. Between them the two projects raised movement capacity from 68 to 94 aircraft an hour, and AOT's published annual passenger capacity from 45 million to 60 million.
AOT publishes where each option is in the building and when it runs. The table below is taken from its own transport page.
| How you travel | Where in the terminal | Hours the operator publishes |
|---|---|---|
| Airport Rail Link | Level B1 | 05:30 to 24:00 |
| Metered taxi | Level 1, between Gates 4 and 7, inner kerb | 24 hours |
| Airport limousine | Level 2 | 24 hours |
| Self-drive car hire | Level 2, Gate 7 | Not published |
| Buses and coaches | Public Transportation Center, and Level 1 at Gates 7 and 8 | Varies by route |
| Shuttle bus to Don Muang | Level 2, Gate 3, inner kerb | 05:00 to 24:00 |
The Airport Rail Link runs between the airport and central Bangkok, from Level B1 of the main terminal, between 05:30 and 24:00. It has eight stations over 28.6 km, and the ride from the airport to Phaya Thai takes about 27 minutes. Trains run every 10 to 11 minutes at peak and every 12 to 13 minutes off peak.
Phaya Thai is the interchange with the Sukhumvit Line, Makkasan connects to the Blue Line at Phetchaburi, and Hua Mak is the interchange with the Yellow Line. Asia Era One has operated the airport line since October 2021.
Anything you read elsewhere promising a fifteen-minute express run into the city is out of date: that service was suspended in September 2014 and has not resumed. The commuter service is the one that runs, at about 27 minutes to Phaya Thai. Phaya Thai is where the city network takes over, and getting around Bangkok covers that side of the trip.
Metered taxis leave from Level 1, between Gates 4 and 7 on the inner kerb, at any hour. Grab picks up from Level 1 at Gate 4, on the outer kerb. The airport limousine service works from Level 2, and self-drive car hire from Level 2 at Gate 7.
A fixed airport surcharge is added to what the meter shows on a taxi.
Three expressways serve the airport: the Bangkok-Chonburi Motorway, the Burapha Withi Expressway and the Suvarnabhumi Airport Link.
Public buses, intercity coaches and public vans work from the Public Transportation Center. Public buses also stop at Level 1, Gate 7, and intercity coaches at Level 1, Gate 8.
AOT also lists an internal circulator shuttle, from Level 2 at Gates 3 and 4 and from Level 1 at Gates 3 and 7.
The shuttle bus to Don Muang leaves from Level 2, Gate 3, on the inner kerb, between 05:00 and 24:00. To board it you need a connecting boarding pass or ticket, plus a passport or identity card.
The shuttle is for connecting passengers, so a separately booked pair of flights may not qualify. Have another way between the two airports in mind in case it does not, and see transfers between Suvarnabhumi and Don Muang for that journey in full.
Departures are on Level 4 of the main terminal and arrivals on Level 2.
AOT's own facilities pages list the Miracle Transit Hotel, which operates airside, open 24 hours, with rooms let for periods of six to twelve hours.
Suvarnabhumi opened for domestic flights on 15 September 2006 and reached full commercial operation on 28 September 2006. It was designed by Helmut Jahn of Murphy/Jahn Architects, and the site covers about 3,520 hectares. Traffic through the airport was more than 62 million passengers in the 2024 calendar year.
The airport operates 24 hours a day, and its name means "the golden land". The Bangkok destination guide covers the city the airport serves.
This site's route data covers domestic flights from Bangkok to destinations including Chiang Mai Airport, Phuket Airport, Krabi Airport and Koh Samui Airport. Each route has its own page, such as Bangkok to Chiang Mai and Bangkok to Koh Samui, carrying the schedule the site holds for it.
