Bangkok has two airports - Suvarnabhumi Airport (BKK) and Don Mueang Airport (DMK). Traveling between them can be done in several ways but the cheapest way is taking a free shuttle bus service BKK to DMK / DMK to BKK.
We would recommend you to use it because the bus is running all the way through expressway (Din Daeng Expressway & Don Mueang Tollway) which is very convenient and, of course, free of charge.
The bus is white colored and with air-conditioning. There is a storage area for luggage inside the bus so there is no problem with having a big luggage. The service is first come, first served so no pre-booking is required.
Shuttle Bus Timetable
While Scheduled times of shuttle bus departure were previously displayed in the Airport Shuttle Bus Timetable found at the bus stop, recently it was removed most probably because buses seem not to follow that timetable very strictly.
The shuttle bus runs daily. The first bus starts running from both airports at 5:00 and the last bus leaves at 24:00. The bus departs every 12 or 30 minutes depending on the time of the day. Previously displayed airport shuttle bus schedule is as follows:
- At periods 05:00-08:00, 11:00-16:00 and 19:00-24:00 the airport shuttle bus departs every 30 minutes
- At periods 08:00-11:00 and 16:00-19:00 the airport shuttle bus departs every 12 minutes
As the schedule might be not that strictly followed, depending on traffic situation, you should better check the digital board at the bus stop to see the estimated time of the next bus departure.
The journey to another airport takes approximately 50-60 minutes. However, it might take twice that time when using shuttle bus service during the rush hour or heavy rain as it may be delayed due to traffic congestion.
Shuttle Bus Route Map
At the bus stop you can find a digital board displaying the shuttle bus route map, estimated time of the next departure and current location of all the buses on the route as well as their estimated arrival time.
