Sihanouk International Airport (KOS) Guide: Preah Sihanouk, Cambodia

Sihanouk International Airport is the air gateway to Sihanoukville, Koh Rong, Koh Rong Sanloem, and Cambodia’s southern coast. KOS is useful when flights operate, but island travelers should plan the airport-to-pier transfer and ferry timing before buying the ticket.

This guide is written for travelers who want the useful details first: the real airport name, where it sits, how much to budget for transport, what to expect in the terminal, where to search for flights, and which services to arrange before landing. Prices and routes are updated for June 2026 and should be treated as practical planning ranges rather than fixed promises.

Transport tips

🧾 Confirm the fare before loading luggage, especially when there is no visible meter or posted rate.
📍 Save the exact hotel pin offline; airport drivers may know districts better than street names.
💵 Carry small local cash for the first transfer, baggage carts, snacks, or phone calls.
🌐 Install an eSIM before departure so you can message your driver immediately after landing.

Public transport and metro

Sihanoukville has no metro and no airport rail link.

Where public transport exists, it is usually best for daylight arrivals with light luggage. For late flights, family travel, heavy bags, or first-time visits, a taxi, hotel transfer, or pre-booked private driver is usually worth the extra cost.

Taxi prices and transfer strategy

Taxi prices around airports are rarely as neat as an official table. Time of day, luggage, driver availability, fuel prices, and whether the destination is inside or outside the central city all matter. The ranges above are realistic planning budgets, but the best practice is simple: agree the fare before moving, keep your phone map open, and avoid changing money with random drivers.

For smoother arrival logistics:

🚕 Use official taxi ranks or a hotel-arranged driver where available.
🧳 Pre-book a transfer if you land late, carry equipment, or travel with children.
🚗 Compare rental cars before arrival with DiscoverCars if you need regional freedom.
🏨 Use Expedia to check hotels near the airport and in the city before choosing a transfer.

Airport facilities, shops, and restaurants

Terminal with check-in, baggage, cafes/snacks, shops, taxi/hotel shuttle pickup, parking, and basic passenger services.
Flight volume can vary with regional tourism demand.
Sihanoukville road traffic and construction can affect transfer times.
Island transfers should be booked with a buffer for delays.

The smart rule at KOS is to treat the terminal as a transfer point rather than as a shopping destination. Eat before arriving when possible, keep a refillable bottle where security rules allow, and bring a small power bank. If you have a long delay, an airport-area hotel or city hotel is usually more comfortable than waiting in the terminal.

Airlines and where the airport flies

KOS route options change with tourism demand. Search Phnom Penh, Siem Reap, Dara Sakor, Kuala Lumpur, Bangkok, Ho Chi Minh City, and China leisure routes where scheduled.

Air Cambodia, Cambodia Angkor Air-style domestic services, Chinese leisure carriers, and regional Southeast Asian airlines are the first names to check.

Cheap routes to check first

Sihanoukville to Phnom Penh: compare flight versus road time.
Sihanoukville to Siem Reap: useful Cambodia triangle route.
Sihanoukville to China/regional hubs: check seasonal availability carefully.

Cheap airport strategy is different from simply sorting by lowest fare. Always compare the final cost after checked baggage, seat selection, payment fees, transfer costs, and missed-connection risk. A slightly more expensive flight into the correct airport can be cheaper than a low base fare that forces a long taxi ride or overnight hotel.

Where to buy flights and hotels

Start with broad searches, then verify the exact airport code before paying. This is especially important in cities with more than one airport or with airport transitions.

eSIM, internet, insurance, and car rental

🌐 Internet: install Yesim eSIM before the flight. Airport Wi-Fi can be slow, blocked by SMS verification, or unavailable exactly when you need maps.
🛡️ Insurance: compare policy wording with SafetyWing. Read exclusions for the destination, adventure activities, medical evacuation, political/security events, and pre-existing conditions.

🎟️ Tours: use Viator for airport transfers, city tours, day trips, and guided experiences when independent transport is inconvenient.

Practical arrival checklist

Before you fly	Why it matters
Check the IATA code on the ticket	Prevents booking a hotel or transfer for the wrong airport.
Save airline, hotel, and driver contacts offline	Messaging apps may not work until data is active.
Carry local cash	Useful for taxis, snacks, and small airport expenses.
Recheck live departures	Regional schedules can change more quickly than major-hub schedules.
Keep insurance documents accessible	Helps at medical facilities and during airline disruption.

Safety and travel notes

Use known taxis or hotel transfers, avoid late unofficial pier rides, and keep insurance active for boat/island travel.

The most reliable traveler is the boringly prepared traveler: documents printed, data working, transport confirmed, hotel address saved, and enough time between every moving part of the itinerary.

Short airport excursion idea

If you have a long layover or an overnight stop, choose one simple plan rather than trying to see everything. Stay close to the city center or a known hotel district, keep the return transfer booked, and avoid cutting the return to the airport too close. In smaller airports, a missed flight may mean waiting a day or more for the next practical departure.
