Bangkok has two major airports, roughly 40 km apart by road. Suvarnabhumi (BKK), east of the city, is the main international hub used by Thai Airways and most full-service and long-haul airlines. Don Mueang (DMK), on the northern edge, is the budget hub for Thai AirAsia, Nok Air and Thai Lion Air — so your airline, not you, usually decides.
The catch: many booking sites label both simply as “Bangkok”, and the AirAsia group now splits some flights between the two. From our 24-hour counters inside both airports — B Floor at Suvarnabhumi, Terminal 2 Gate 9 at Don Mueang — we meet travelers every week who discovered the difference the night before a flight. Below: who flies where, how to reach the city from each, how to move between them, and how each terminal is laid out.
What’s the difference between BKK and DMK?
Suvarnabhumi opened in 2006 as Bangkok’s primary gateway and, as of 2025, is served by more airlines than any other airport in the world. Don Mueang is its opposite in almost every way: first opened in 1914, it is one of the world’s oldest operating airports and has become the de facto base for Southeast Asian budget air travel.
| Suvarnabhumi (BKK) | Don Mueang (DMK) | |
|---|---|---|
| Role | Main international hub | Low-cost carrier base |
| Opened | 2006 | 1914 (among the world’s oldest) |
| Location | About 25 km east of downtown, in Samut Prakan | Don Mueang district, northern edge of Bangkok |
| Home airlines | Thai Airways, Bangkok Airways, Thai Vietjet, most long-haul carriers | Thai AirAsia, Thai AirAsia X, Nok Air, Thai Lion Air |
| Terminals | One main terminal + SAT-1 satellite, linked by driverless train | Terminal 1 (international) + Terminal 2 (domestic), linked by walkway |
| Rail into town | Airport Rail Link: ~30 min to Phaya Thai, ฿45 | SRT Red Line: ~17 min to Krung Thep Aphiwat, ฿33 |
| Capacity | ~60 million passengers/year | ~30 million passengers/year |
| 24h luggage storage | AIRPORTELs, B Floor (Airport Rail Link zone) | AIRPORTELs, Terminal 2, 1st Floor, Gate 9 |
Which airlines fly from which Bangkok airport?
As a rule of thumb: full-service and long-haul flights use Suvarnabhumi; short-haul budget flights use Don Mueang. Specifically, as of July 2026:
- Suvarnabhumi (BKK): Thai Airways (its home hub), Bangkok Airways, and virtually every foreign full-service carrier — plus, less obviously, the low-cost airline Thai Vietjet, which is based at BKK, not DMK.
- Don Mueang (DMK): the primary operating base of Thai AirAsia, Thai AirAsia X, Nok Air and Thai Lion Air.
The picture has blurred in recent years — the AirAsia group also operates some flights from Suvarnabhumi — so treat the three-letter code on your ticket as the only reliable answer. The most expensive mistake we see at our counters: travelers who ride to BKK for a flight that leaves from DMK.
How do I get into central Bangkok from each airport?
From Suvarnabhumi (BKK)
The Airport Rail Link City Line leaves from the B Floor (the same level as our storage counter) and reaches Phaya Thai, where you can change to the BTS Skytrain, in about 30 minutes for ฿45. Trains run from roughly 05:30 to midnight, every 10–15 minutes. Metered taxis wait on Level 1; expect 40 minutes to well over an hour to central Bangkok depending on traffic, plus expressway tolls and a small airport surcharge.
From Don Mueang (DMK)
The SRT Dark Red Line runs from Don Mueang station — reached by a covered walkway from the Terminal 2 end of the airport — to Krung Thep Aphiwat Central Terminal in about 17 minutes for ฿33, with an MRT connection onward. The A1 bus to Mo Chit BTS/MRT (฿30, roughly 06:00–midnight) and the A2 to Victory Monument (฿30) are the classic budget options, and metered taxis queue outside the arrivals level. If your hotel is near Chatuchak or northern Sukhumvit, DMK is often the faster airport door-to-door.
How do I transfer between Suvarnabhumi and Don Mueang?
There is no direct rail link between the two airports, but there are three workable options, as of July 2026:
- Free AOT shuttle bus — free for passengers with a boarding pass or ticket for an onward flight from the other airport (show it with your passport). Runs about 05:00 to midnight: from Suvarnabhumi at Level 2 (Arrivals) outside Gate 3; from Don Mueang at Terminal 1, 1st Floor, Gate 6. First-come, first-served.
- Taxi or ride-hailing — typically ฿400–500 on the meter plus tolls. The drive takes about 45 minutes with clear roads and up to two hours in rush hour.
- Rail with transfers — Airport Rail Link to Phaya Thai, BTS/MRT across town, then Red Line to Don Mueang. Cheap, traffic-proof, and honestly miserable with two suitcases in tow.
Whichever you choose, we recommend at least four hours between separately booked flights at different airports — the road between them is one of Bangkok’s least predictable.
How are the terminals laid out at each airport?
Suvarnabhumi: one giant terminal plus a satellite
BKK is a single massive building: departures and check-in on Level 4, arrivals on Level 2, buses and taxis on Level 1, and the Airport Rail Link on the B Floor underground. Since September 2023, the SAT-1 satellite concourse (28 extra gates) handles some departures via a short driverless people-mover ride; if your gate number starts with S, budget extra time. A third runway entered full operation in November 2024, lifting the airport from 68 to 94 flights per hour.
Don Mueang: two terminals, one walkway
DMK splits cleanly: Terminal 1 for international flights, Terminal 2 for domestic, connected by an enclosed elevated walkway. It is an older, simpler airport: shorter walks to gates, but fewer lounges, shops and late-night food options than BKK. Both our 24-hour counter (Gate 9) and the Red Line walkway sit at the Terminal 2 end of the building.
Which Bangkok airport is better for your trip?
Honestly, you rarely get to choose — the airline decides. When fares are similar, here is how we would call it:
- Long-haul or connecting internationally: BKK, no contest — it is where the network carriers live.
- Cheapest fares to regional and domestic destinations: usually DMK, where the low-cost carriers are based.
- Staying near Sukhumvit or Siam: BKK’s one-seat Airport Rail Link ride is easier with luggage.
- Staying in northern Bangkok, or connecting by train elsewhere in Thailand: DMK, with its 17-minute Red Line hop to Krung Thep Aphiwat, Bangkok’s main rail terminal.
- Quick domestic hops: DMK’s compact terminals mean shorter curb-to-gate times than BKK’s long concourses.
Where can I store or send luggage at either airport?
This is the part we know first-hand: AIRPORTELs runs staffed, 24-hour luggage counters inside both airports — on Suvarnabhumi’s B Floor in the Airport Rail Link zone, and at Don Mueang’s Terminal 2, 1st Floor, Gate 9. Storage is ฿100 per bag per day at any size, with every bag x-ray screened, tagged, photo-logged and insured up to ฿50,000 per booking; same-day luggage delivery across Bangkok starts at ฿299 for bags up to 25 kg (as of July 2026). That combination is the clean fix for the two-airport transfer: store bags on landing, or send them to your hotel and ride the free shuttle empty-handed. Full pricing is on our Suvarnabhumi storage page and Don Mueang storage page; every operator at both airports — competitors included — is compared honestly in our Bangkok airport luggage storage comparison.
What else do travelers ask about Bangkok’s two airports?
Are BKK and DMK the same airport?
No. Suvarnabhumi (BKK) and Don Mueang (DMK) are separate airports roughly 40 km apart by road, on opposite sides of Bangkok. Always check the three-letter code on your booking, because some airlines and booking sites label both simply as Bangkok.
How long does it take to travel between BKK and DMK?
Allow at least an hour on the road, and up to two hours in heavy traffic. A free AOT shuttle links the two airports for passengers holding a boarding pass or ticket for an onward flight, and a taxi typically costs around 400-500 baht plus tolls, as of July 2026.
Which Bangkok airport is closer to the city centre?
Neither is clearly closer, because they sit on opposite sides of the city. Suvarnabhumi is about 25 km east of downtown, a roughly 30-minute Airport Rail Link ride to Phaya Thai. Don Mueang sits on the northern edge, about 17 minutes from Krung Thep Aphiwat station on the SRT Red Line.
Can I store luggage at both Bangkok airports?
Yes. AIRPORTELs runs 24-hour staffed counters at both airports: on the B Floor of Suvarnabhumi in the Airport Rail Link zone, and at Don Mueang Terminal 2, 1st Floor, Gate 9. Storage costs 100 baht per bag per day at any size, insured up to 50,000 baht per booking, as of July 2026.
Whichever airport your ticket says, the goal is the same: moving through Thailand hands-free, with your luggage handled by someone whose whole job is exactly that.
