With Koh Samui being situated only about one hour from Bangkok by airplane, Bangkok Airways operates flights to and from the island nearly every hour flight from 6 am to 10 pm daily. Thai Airways runs 2 flights everyday between Bangkok and Koh Samui as well. A less expensive but longer option is to fly from Bangkok to Surat Thani, a city on Thailand's south-eastern coast and a bus and ferry-ride from Koh Samui. A flight from Bangkok to Surat Thani can be booked with low cost carriers Air Asia, Nok Air and Lion Air. From the airport travellers can catch a minibus or van for the hour and half ride to Donsak Pier, east of Surat Thani. From Don Sak pier ferries depart every 30 minutes for Koh Samui.
