Free Airport Shuttle Bus Between Bangkok Suvarnabhumi and Don Muang

A free shuttle bus for passengers links Bangkok’s two airports, Suvarnabhumi(airport code BKK) and Don Muang (airport code DMK). It can be a convenient option if you need to transit between the two, but if your flight connection times are tight you may still be best advised to take a taxi direct.

From Bangkok Suvarnabhumi airport to Don Muang

The shuttle bus departs from Bangkok Suvarnabhumi on the 2nd Floor (arrivals) outside Door 3. The shuttle bus service is clearly sign-posted from the arrivals hall. Outside Door 3 you will see a despatch desk where you should contact the staff. A sign by the desk says you need to show a boarding pass/proof of travel, but when I’ve used the service I only had flight details as a memo on my phone and was told ‘no problem’ and didn’t even need to show that. If you’re carrying luggage and are a genuine passenger transiting between the two airports you shouldn’t have any problems, but be prepared to show your flight details if requested.

From Don Muang airport to Suvarnabhumi

For passengers going from Don Muang to Suvarnabhumi airport, the shuttle bus departs from outside the passenger terminal at Don Muang and is clearly sign-posted. On arrival at Suvarnabhumi, the bus drops passengers at the departure terminal on the 4th Floor by Gate 5.

Journey times

The shuttle bus service is operated by Airports of Thailand (AOT) and their target time for the journey between Bangkok Suvarnabhumi and Don Muang is 50 minutes. The times I’ve used the service have been off-peak and in good weather and the journey has always been punctual. If you are travelling during rush hour and/or in heavy rain, then journey times may be longer.
