Singapore to Koh Samui — Direct Flights 2026
The best way to travel from Singapore to Koh Samui is the direct flight. Two airlines operate the nonstop Singapore to Koh Samui route in 2026, both flying from Singapore Changi Airport (Terminal 1) directly to Samui Airport (USM):
| Airline | Type | Flight Time | Frequency | From (one way) |
|---|---|---|---|---|
| Scoot | Direct nonstop | ~1h55 | ~4 daily | ~$140 |
| Bangkok Airways | Direct nonstop | ~1h55 | ~2 daily | ~$160 |
Between them, Bangkok Airways and Scoot operate around 45 nonstop flights per week on the Singapore to Koh Samui route — so you have plenty of departure times to choose from, from an early 06:30 departure through to a late 20:15 flight. Both airlines use the same efficient Embraer E190/E2 aircraft on this route.
Scoot is the budget option — cheaper base fares (from ~$140), but you pay extra for baggage, seat selection and food. Best for light packers watching the budget. Bangkok Airways is the full-service choice — checked baggage, a snack and even lounge access included on most fares, plus a more generous schedule for connections. Worth the extra ~$20 if you're bringing luggage or want a smoother experience. For most beach holidays, compare both on the same dates — the price gap narrows once you add Scoot's baggage fees.

Singapore to Koh Samui Flight Time
The Singapore to Koh Samui flight time is approximately 1 hour 55 minutes nonstop — one of the quickest international island hops from Singapore. The distance is around 1,000 km (626 miles), flown directly across the Gulf of Thailand. The return leg (Koh Samui to Singapore) takes marginally longer at around 2h10 due to prevailing winds.
There is a 1-hour time difference between Singapore and Koh Samui — Thailand is 1 hour behind Singapore. A flight departing Singapore at 07:00 arrives in Koh Samui at around 07:55 local time, giving you a full day on the island on arrival day.
Singapore to Koh Samui — Prices & When to Book
Flight prices on the Singapore to Koh Samui route vary significantly by season and how far ahead you book:
| Period | Typical One-Way Fare | Round Trip | Notes |
|---|---|---|---|
| Low season (Sep–Oct) | $130–160 | $270–320 | Cheapest — but Samui's rainy season |
| Shoulder (May–Jun) | $150–180 | $300–360 | Good value, decent weather |
| High season (Dec–Feb) | $200–280 | $400–550 | Peak — book 6+ weeks ahead |
| Peak holidays (NYE, CNY) | $280–400 | $550–800 | Book 2–3 months ahead |
The sweet spot for booking is around 6 weeks (40 days) in advance for the best fares. Tuesday, Wednesday and Saturday departures are typically cheapest, and Scoot usually has the lowest base fares. Set a price alert and book when you see a fare in the low range for your season — prices on this route move quickly, especially into high season.
The Cheaper Alternative — Fly to Bangkok, Then Ferry
If the direct Singapore to Koh Samui fare is high for your dates, there's a budget alternative: fly Singapore → Bangkok (often very cheap on Scoot, AirAsia or Jetstar), then continue to Koh Samui by domestic flight or the bus-and-ferry combination. This can save money in peak season, at the cost of extra travel time.
| Route Option | Total Time | Typical Cost | Best For |
|---|---|---|---|
| Direct SIN → USM | ~2h | $140–280 | Speed & convenience (recommended) |
| SIN → Bangkok → USM (fly) | ~5–7h | $120–220 | Sometimes cheaper in peak season |
| SIN → Bangkok → bus+ferry | ~12–15h | $100–160 | Tightest budgets · Backpackers |
If you fly into Bangkok first, the onward domestic flight (Bangkok Airways) or the bus-and-ferry combination to Koh Samui is easy to book in one place — compare flights, buses and ferries with live prices and instant e-tickets.
Arriving at Koh Samui Airport (USM)
