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 traveling during rush-hour and/or in heavy rain, then journey times may be longer.
There are regular departures from 05.00 am in both directions.
