Traveling by Airplane is the fastest and most comfortable way to get to Koh Phangan island. Now Koh Phangan airport is under construction, and Koh Samui Airport (USM) is Phangan's closest airport. On arrival at the cosy airport of Koh Samui you can ask the information desk for a taxi and boat ticket to Koh Phangan.
Alternatively you can fly to the airports of Suratthani, Nakhon Si Thammarat and Chumphon on the mainland as well, from there you travel by bus and boat to Koh Phangan.
Thai Airways flies to Surathani daily. This costs about 2000 baht one way. You then take the transfer to the ferry pier, and boat to Koh Phangan. Solar Air flies to Chumphon, while Air Asia flies to Nakon Sri Thammarat, all cheap!
