Arrival at Surat Thani Airport for Flights Departing Before 11:00

A word of caution with this journey: if your flight is before 11:00, you need to travel to Surat Thani the night before and stay in a hotel. For flights from Surat Thani Airport the minimum time you must arrive before the plane is scheduled to depart is 45 minutes. Arrive after this and you may miss your flight.

Travel in Thailand is frequently subject to unforeseeable delays. This is particularly the case when boat journeys are involved. The weather in the Gulf of Thailand can change suddenly and in stormy seas the journey can take longer than expected and the ferry might not arrive on time either. To avoid missing your flight when you travel from Koh Samui, you need to leave yourself extra time – don’t count on anything being exactly on time, as generally it is not.

In you are in doubt over whether you can make in time for your flight we advise you to book a hotel in Surat Thani. The best hotels are the Diamond Plaza, Wang Tai, and 100 Islands Resort.
