Flying from Bangkok to Koh Samui
In short
Only one airline flies nonstop from Bangkok to Koh Samui: Bangkok Airways, which leaves from Suvarnabhumi (BKK) and also from Don Mueang (DMK). The flight covers about 467 km and takes about 1 hour.
That near-monopoly has a history. Bangkok Airways built Samui airport, opened it in April 1989 and still owns and runs it, and the 2,100 m runway only takes narrow-body jets and turboprops. Thai Airways sells seats to Samui too, but they are on Bangkok Airways aircraft under a codeshare. The result is a pleasant, small-scale airport and fares that are usually higher than flights to Surat Thani on the mainland.
Suvarnabhumi connections with bags checked through
Most Samui flights leave from Suvarnabhumi, which is the place to connect if you arrive in Thailand on a long-haul flight. Book Samui on the same ticket, or on a Thai Airways codeshare, and your bags go through. Bangkok Airways passengers can use the airline's lounges there. The airline also runs Samui flights from Don Mueang, handy if you are staying in north Bangkok. Either way, standard economy includes a checked bag.
Thatched pavilions at Bo Phut, 2 km from Chaweng
Samui International Airport is a group of thatched, open-sided pavilions in gardens at Bo Phut, on the north-east corner of the island. You may ride an open tram from the aircraft. Chaweng's northern end is only about 2 km away, 15 to 20 minutes by car to the centre. Taxis charge fixed prices by zone and do not use the meter, so agree the fare at the counter; shared minibuses sold in arrivals are cheaper and drop at hotels along the way. For Koh Phangan, Big Buddha Pier is a few minutes from the terminal, and Koh Tao ferries leave from Maenam, about 6 km away. The airport closes overnight, so a delayed evening arrival will not leave you stuck there.
Samui's wettest months fall at the end of the year
Samui's seasons do not match Phuket's. The heaviest rain falls from about October to December, with November usually the wettest month, while January to April is dry and sunny and the middle of the year is often good too. That makes Samui a sensible choice when the Andaman coast is in its monsoon.
Bangkok Airways built it and opened it in 1989
Samui International Airport is privately owned and was built by Bangkok Airways. Construction began in 1982 and the airport opened in April 1989. It now handles more than a million passengers a year, making it Thailand's seventh-busiest airport.

Frequently Asked Questions (FAQs)
Getting there
Bangkok Airways built Samui airport and still owns and runs it, so it controls most of the slots. Thai Airways sells Samui seats, but they are on Bangkok Airways aircraft under a codeshare.
About 2 km to the northern end of Chaweng. Allow 15 to 20 minutes by car to the centre, longer on a shared minibus that stops at several hotels.
No. They charge fixed prices by zone. Confirm the fare at the counter before you get in; Lamai and the south of the island cost more than Chaweng or Bophut.
Small and open-air. The terminals are thatched pavilions in gardens, you may be taken to the aircraft by open-sided tram, and the landside shopping street is called Samui Park Avenue.
Big Buddha Pier is a few minutes from the airport and has boats to Koh Phangan. A taxi to the pier is the easiest way with luggage.
No. It opens for the morning departures and closes after the evening flights, so it is not a place to wait overnight.
Yes, and it is the simplest way to reach the island from abroad. On a single ticket with Bangkok Airways or a partner, your bags are checked through to Samui.
General
Yes. Bangkok Airways flies Samui from Don Mueang as well as from Suvarnabhumi. Check which airport is on your ticket before heading out.

Timing & weather
Roughly October to December, with November usually the wettest month. January to April is the driest period, and mid-year weather is often better than on the Andaman coast.
What's included
