Bangkok Arrival: Suvarnabhumi, Don Mueang, and the Airport Rail Link

Suvarnabhumi is 30 kilometers east of central Bangkok. It has one terminal with two arrival levels. The Airport Rail Link runs from the basement of the terminal to Phaya Thai station in central Bangkok in 26 minutes for 45 baht. Phaya Thai connects to the BTS Skytrain, which reaches almost everywhere a first time visitor wants to go.

The Rail Link is the correct choice for any arrival not carrying more than two large suitcases per person. It runs from 05:30 to 00:00 every 10 to 15 minutes. Trains are clean, air conditioned, and rarely full.

For hotels near the river, in the old town, or in the Sathorn area, take the Rail Link to Phaya Thai and switch to BTS. For Sukhumvit hotels, get off at Makkasan and switch to MRT one stop to Sukhumvit. The math works out in the app and does not need memorising.

Suvarnabhumi has an official public taxi rank on Level 1, outside gates 4 and 7. This is a metered rank with a 50 baht airport surcharge and expressway tolls of about 70 baht payable to the driver. A ride to Sukhumvit costs around 350 to 450 baht total, 300 to 400 to Silom, 400 to 500 to the river. This is honest.

The trap is the fixed price desk inside the terminal. It advertises taxis for 800 to 1200 baht to the same destinations. Do not use it. Walk down the escalator, get in the metered queue, insist on the meter if the driver tries to negotiate, and pay the tolls in cash as they occur.

Grab, the local rideshare app, works well from Suvarnabhumi and is priced between the metered taxi and the fixed desk. It is the correct choice at 03:00 when the metered queue is long and the drivers who remain are refusing to run the meter.

Don Mueang is 25 kilometers north of central Bangkok. It has two terminals, Terminal 1 for international and Terminal 2 for domestic. It is used almost exclusively by low cost carriers.

Don Mueang is closer to central Bangkok than Suvarnabhumi in kilometers but often slower to reach because the highway approaches are more traffic prone. There is a rail station at Don Mueang served by the Red Line commuter train, opened in 2021, which reaches Bang Sue Grand Station in 20 minutes for 33 baht. From Bang Sue you connect to the MRT Blue Line into central Bangkok. Total time to Sukhumvit: about 55 to 70 minutes for 60 baht.

The metered taxi from Don Mueang to central Bangkok costs 250 to 400 baht plus tolls in light traffic. In evening rush it can double in time and modestly in fare. Grab is again a good midpoint.

If your flight is on Thai Airways, Emirates, Qatar, ANA, or any major full service carrier, you are almost certainly landing at Suvarnabhumi. If your flight is on AirAsia, Nok Air, Thai Lion, or a similar low cost carrier from within Asia, it is Don Mueang.

For a first Bangkok visit, Suvarnabhumi is easier. The airport is newer, the Rail Link is faster, the taxi rank is more organized, and the signage is better in English. Don Mueang is fine for a return visitor who knows the city and does not need to think about the transfer.

If your journey involves connecting between an international flight into Suvarnabhumi and a domestic AirAsia flight out of Don Mueang, you are in for a 90 minute inter-airport transfer, minimum. There is a free shuttle bus between the two airports for passengers with boarding passes for both flights, but the schedule is unreliable and the loading is chaotic. Allow four hours between arrival at Suvarnabhumi and departure from Don Mueang. Six hours if either flight is delayed.
