Route data is updated regularly from official airline schedules. On-time performance data comes from recent airport delay snapshots.
Yes. Bangkok Airways holds a concession agreement with the Koh Samui Airport Authority that makes it the sole airline at USM. No other carrier has permission to operate scheduled service to or from Koh Samui Airport. Bangkok Airways built and owns Koh Samui Airport, and the concession arrangement is the structural reason for the monopoly. This applies to both BKK-USM and connections from other Thai cities.
Bangkok Airways operates from Terminal 1 at Suvarnabhumi, using gates in the B concourse area for domestic departures. Bangkok Airways operates its own Blue Ribbon Club lounge at Suvarnabhumi, which is open to all passengers regardless of ticket class. This is the airline's well-known policy. The lounge provides snacks, drinks, and seating at no extra cost. At Koh Samui Airport, all passengers have access to the open-air lounge facilities, also at no charge.
Bangkok Airways flies ATR 72-600 turboprop aircraft on BKK-USM. The flight takes 1 hour 15 minutes. There are no jet options for this route given USM's runway constraints. The ATR 72 holds 70 passengers and operates in a single-class configuration. Baggage is typically loaded by hand due to the aircraft's unpressurised hold design; fragile items may be better kept as carry-on.
Bangkok Suvarnabhumi to Koh Samui: Bangkok Airways' Monopoly Route
BKK-USM is one of the few scheduled airline routes in Asia with a formal single-carrier structure. Bangkok Airways built Koh Samui Airport in 1989 and holds the operating concession, making it the only airline permitted to fly scheduled service to USM. It operates 8 to 10 daily round trips using ATR 72-600 turboprops, with block time of 1 hour 15 minutes. The concession model means fares are substantially higher than comparable Thai domestic routes operated under competition. Passengers without the budget for BKK-USM often route through Surat Thani (URT) by air or overnight train, then take the ferry to Samui. That alternative adds 3 to 5 hours to the journey.
Koh Samui Airport and Bangkok Airways' Network
USM is a distinctive open-air airport with thatched-roof pavilions built by Bangkok Airways on a private concession. The design is intentionally low-capacity, limited to small turboprop aircraft. Bangkok Airways also connects Samui to Chiang Mai (CNX), Phuket (HKT), and select international points including Singapore and Hong Kong, all as extensions of the concession model. The free lounge access policy at BKK and USM is a genuine differentiator; passengers on the shortest, cheapest fare have the same lounge access as premium-class travellers. Suvarnabhumi's domestic gates for Bangkok Airways sit in the B concourse, separate from the international gates used by Thai Airways and other mainline carriers.
