Koh Samui Airport (USM) in Thailand

Koh Samui Airport (USM) is often the first thing you see of the island — and because it looks so different from an ordinary airport, it tends to stick in travellers' memories. Here's the 2026 overview: what makes it unusual, which airlines fly there directly, why fares tend to run higher, how to get onward to your hotel, and how far it is to the main beaches.

A private airport with open-air terminals

Koh Samui Airport opened on 25 April 1989 and is still owned by Bangkok Airways — making it Thailand's only privately operated airport. Instead of enclosed halls, you're greeted by open terminal areas set among tropical planting; only a handful of spaces, such as offices, restrooms and the lounge, are air-conditioned. Rather than a bus, an open-sided tram takes you to your aircraft — a detail that puts many arriving passengers straight in holiday mood.

In 2026, Bangkok Airways announced a major expansion: roughly 600 to 700 million THB earmarked for new gates (up from 7 to 11), more check-in counters and larger retail space, with construction starting in the second quarter of 2026 and completion planned by 2030. The goal is a capacity of 6 million passengers a year. During construction, expect the odd diversion within the terminal — allow a little extra time on busy days.

The airport has only been able to handle international traffic since 1996, when its own customs and immigration facilities opened, including visa-on-arrival for nationalities that need it. Before that, every international trip involved a connection on the mainland.

Facilities: shops, a lounge and a few extras

The "Samui Park Avenue" retail and dining area includes a branch of the silk brand Jim Thompson, the skincare brand Harnn, and several cafés and restaurants for the wait before boarding. If you'd rather wait somewhere quieter, the "Blue Ribbon Club" lounge charges a walk-in fee of around 950 THB, or you can use a Priority Pass membership. A few small extras that surprise many travellers: comfortable seating rather than the usual metal benches, and photo spots overlooking the runway.

Some passengers also pay for a fast-track service through immigration (also around 950 THB) — though with normal passenger volumes this is rarely necessary, since arrivals and baggage claim tend to move quickly according to most traveller reports.

Which airlines fly directly to Koh Samui?

Because Bangkok Airways owns the airport, it also dominates the route network. Domestically, there are direct flights to Bangkok (both Suvarnabhumi and Don Mueang), Chiang Mai, Krabi and Phuket. Internationally, Bangkok Airways connects Koh Samui with Hong Kong and Singapore; Scoot also flies the Singapore route, and Berjaya Air links the island with Kuala Lumpur-Subang. There is no direct flight from Europe, North America, Australia or other overseas regions — you land in Bangkok first and take a connecting flight from there.

Why are flights to Koh Samui more expensive?

Because Bangkok Airways owns and runs the airport, it also sets the landing fees other carriers must pay for slots on the route. That limits competition and is the main reason fares to Koh Samui tend to run higher than comparable domestic Thai routes to AOT-run airports such as Phuket or Chiang Mai. The standard airport or passenger service charge is normally already included in the ticket price; unlike Thailand's state-run AOT airports, which raised their international passenger charge in 2026, we could not verify a single, consistently published extra fee specific to Koh Samui itself, so no figure is given here.

Transfer from the airport

In the arrivals area you'll find several options:

• Shuttle bus: the cheapest option for short hops such as Chaweng or Bophut, at a fixed rate lower than a taxi — though with stops along the way rather than door-to-door service.
• Taxi/minivan at a flat rate: most operators use fixed price lists rather than the meter. Short routes such as Chaweng, Bophut or Bang Rak start from around 400 THB, while longer routes such as Thong Krut or Taling Ngam run to 900 THB or more — see our article on getting around Koh Samui for every option on the island.
• Pre-booked private transfer: a driver meets you at the exit holding a name sign — no haggling, no waiting for other passengers.
• Hotel transfer: many hotels and resorts offer their own pick-up, usually bookable for an extra charge.
• Grab: the app works on Koh Samui, though with limited availability. You can't book a Grab car for pick-up right at the terminal — collection happens from a designated area outside. Grab is most reliable around Chaweng, Bophut and the airport itself.

The most relaxed option is a private transfer booked in advance, especially after a long flight:

Distances to Chaweng, Lamai and Bophut

The airport sits in the north-east of the island, close to Bophut. Approximate travel times to the main resort areas:

The further south or west your hotel is (Taling Ngam or Thong Krut, for example), the longer the drive and the higher the flat rate for a taxi or minivan.

Tips for arrival and departure

• Arrive in good time: 1.5 to 2 hours before departure is usually enough for domestic flights, and around 3 hours for international ones — especially during high season and while terminal construction is under way.
• Wi-Fi and SIM cards: you can log straight into the free airport Wi-Fi on arrival, or buy a Thai SIM card from DTAC, AIS or TRUE.
• Keep some cash handy: useful for a taxi, minivan or a quick snack at the counter, even as card payment becomes more common.
• Planning onward travel: heading straight on from Koh Samui, say to a neighbouring island? See our article on how to get to Koh Samui for every ferry and boat connection.

Frequently asked questions

Which airport serves Koh Samui?
