Koh Samui Airport Microbus services started to run this service just beginning of the year 2019
The bus will will run in the circle around the island and come back to the airport again.
From Koh Samui arrival terminal, the microbus will leave 2 buses at the same time but will separate the route later when they arrive at the main road neaby Tesco Lotus. One will turn to Lamai, one will turn to Bophut to Maenam. But all of them will run in the circle coming around Koh Samui and come back to the airport again. Right now they have 8 microbuses available. And will have more in the future.
When you are at the Meeting Point building of Koh Samui airport, you will see the airport microbus just waiting opposite side.

They driver of the microbus will ask you which is your hotel and they will tell you which bus you should get in because they will run Lamai way (south) and Bophut , Maenam way (north) However, it is run in the circle but you will not wasting time if you take the correct way at first.

However, right now Koh Samui Airport Microbus is only available for the people who stay in Lamai area and the hotels that located on the main road of Koh Samui.
The airport microbus will not run pass Choengmon, Bangrak or in Chaweng center. And it is still not really comfortable in case that you are in hurry or if your hotel is not on the main road. Because you still have to walk to the hotel from the main road.
