If you are arriving internationally into Bangkok and wish to head straight onto Koh Samui, you are best advised to travel with THAI Airways. That way your luggage can be checked through from your home town direct to Koh Samui. If you book your Bangkok to Samui flight with Bangkok Airways, you will need to collect your luggage in Bangkok and then check-in again for your Bangkok Airways flight to Samui.
If you’d prefer to stay at Bangkok Airport for the night before continuing your journey onto Koh Samui, there is a four star hotel located directly within the Airport ground – the Novotel Suvarnabhumi. This hotel is accessible by a free shuttlebus or, if you have only a little luggage, a direct walkway from the airport terminal itself and has 24 hour check-in. There are also several hotels located nearby to Suvarnabhumi Airport if you want a greater choice of where to stay.
