Between 05-00 and 00-00 there is a free shuttle bus between the 2 airports it takes approx 1 hour (depending on traffic can be less can be more). The only other realistic option would be a metered taxi.
Thank you for responding! That’s great news - I did see the free shuttle bus option in other forums but they’re from years ago so I wasn’t sure if they’re still available
Would you be able to tell me the directions to find this in the Suvarnabhumi Airport? Thanks :)
Used it last year. Good service as long as you're not in a rush.
