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.
Bangkok Airport Shuttle Bus COVID-19 Update
Even if the number of flights landing at both Bangkok airports is reduced significantly, we can confirm that the free shuttle bus between Suvarnabhumi Airport and Don Mueang Airport is operating during COVID-19 outbreak!
The number of bus departures might be reduced a bit (no official announcement regarding this was notices) but anyway you can easily get on the next bus as they are running almost empty.
Just like always, you need to show the ticket for departing flight from the airport you are traveling to.
The most noticeable change is the seating policy inside the bus as only every second seat can be occupied.
Shuttle Bus Timetable
Scheduled times of shuttle bus departure are displayed in the Airport Shuttle Bus Timetable below.
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. Current 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

The route takes approximately 50-60 minutes to another airport. 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.
