Samui Airport (USM) - key facts

Summary

Koh Samui Airport (USM) is a small, mostly open-air airport in the island's north-east, privately owned and operated by Bangkok Airways since 1989. Most flights connect through Bangkok; fares are higher than typical Thai domestic routes because competition is limited.

Details

Ownership

USM was built by Bangkok Airways in 1989 and remains privately owned and operated by the airline. Bangkok Airways runs most flights; a few other carriers (e.g. Scoot, Thai AirAsia on some routes per 2026 sources) also serve it, but route choice and pricing are limited compared with Thailand's public airports. No direct flights from Europe - international travelers connect via Bangkok or Singapore.

Location

North-east Koh Samui near Bo Phut/Big Buddha, about 2-5 km from Chaweng (10-15 min by road) and about 23 km from Nathon Pier.

Character

Famous for its open-air tropical design - no air-conditioning between gate and baggage claim. Bangkok Airways fares include checked baggage and a meal, which partly offsets the higher headline price.

Alternatives

Budget alternative: fly to Surat Thani (URT) or Nakhon Si Thammarat (NST) on the mainland, then combined bus+ferry to Samui (about 4-5 hours total, roughly $25-30 per 2026 sources).

Local tips

• Book Bangkok-USM flights early in high season; fares rise steeply close to departure.
• The airport is minutes from Bang Rak and Big Buddha piers - convenient for same-day ferry connections to Koh Phangan.
• Arrive with time to spare in peak season; the small terminal gets crowded around midday banks of flights.
• Consider the Surat Thani + ferry route if fares to USM are high.

Bangkok Airways - it built the airport in 1989 and still owns and operates it privately, which is why routes and prices are less competitive than at public Thai airports.

No. Connect via Bangkok (BKK/DMK) or Singapore to USM, or fly to Surat Thani and take a ferry.

How far is Koh Samui airport from Chaweng?

About 2-5 km, roughly 10-15 minutes by car.

Is there a cheaper way to fly to Koh Samui?

Yes: fly to Surat Thani or Nakhon Si Thammarat on the mainland, then take a combined bus+ferry ticket to Samui - longer (about 4-5 hours) but much cheaper.
