A quick view of Surat Thani Airport in Southern Thailand.
This small airport is a cheap way to fly to Bangkok or anywhere else around Thailand.
It is a cheap way to fly to other areas from Koh Samui, as flying out of Koh Samui can be expensive because Bangkok Air owns the airport, so they charge high prices to fly in and out.
If you catch the ferry from Koh Samui to Surat Thani then it is an inexpensive way to get to your other destination.
You can also fly to other Asian countries from the Surat Thani airport.
