🏢 The Terminal & the Carrier Picture

SAI opened on 16 October 2023 and took over from the old Siem Reap International Airport (REP), which sat roughly 8 km from the town centre and could not be expanded any further without encroaching on the Angkor Archaeological Park’s protected airspace and sightlines. The replacement was built far to the east instead — a deliberate choice that kept jet traffic away from the temples but moved the airport about 50 km from the place most people are flying in to see.

It is a single passenger terminal handling both domestic and international flights, designed for around 7 million passengers a year in its first phase. Expansion to roughly 12 million is planned for the end of the decade, with longer-horizon figures pushing higher; treat any capacity number beyond the first phase as a projection rather than a built fact.

The carrier list is regional with a few long-haul exceptions. As of this writing, airlines serving SAI include Air Cambodia (the national carrier, to Ho Chi Minh City, Da Nang, Shenzhen and domestic Phnom Penh), Bangkok Airways (Bangkok), Thai Airways (Bangkok), AirAsia Cambodia and Thai AirAsia (Kuala Lumpur, Phnom Penh, Phu Quoc), Vietnam Airlines and VietJet (Hanoi, Ho Chi Minh City, Luang Prabang), Singapore Airlines (Singapore), China Eastern, Lao Airlines, IndiGo (Kolkata) and Emirates, which runs a Dubai service routed via Bangkok. Most traffic is short-haul into the Bangkok, Singapore and Vietnam hubs; if you are coming from Europe or the Americas, you are almost certainly connecting through one of those.

🛂 Cambodia’s Border Rules at SAI: e-Visa, Visa on Arrival & the e-Arrival Card

Most visitors need a visa for Cambodia, and there are two clean ways to get a tourist one.

e-Visa. Apply in advance at the official site, evisa.gov.kh. The tourist (T-class) e-Visa runs US$30 plus a small processing fee, valid for a 30-day stay. Apply only through the .gov.kh domain — a crowd of third-party sites front the same form and quote US$36–US$70 for the same visa, pocketing the difference as a “service fee.” There is no faster government channel they are buying you; the markup is the product.

Visa on arrival. You can also buy the same 30-day tourist visa at the immigration counter on landing at SAI for US$30. Air arrivals at Siem Reap, Phnom Penh and Sihanoukville can now pay by card or cash, which removes the old need to carry exact US dollars and a passport photo. Bring a passport with at least six months’ validity. The on-arrival queue is the trade-off — at peak banks of inbound flights it is slower than walking up with an e-Visa already approved.

ASEAN nationals travel visa-free, but the allowance is set by bilateral treaty and is not uniform: most get 14 or 30 days depending on nationality (the Philippines, for instance, is shorter than its neighbours). If you hold an ASEAN passport, check your specific allowance rather than assuming 30 days.

The e-Arrival card is separate and mandatory. Every air passenger must complete the free Cambodia e-Arrival (CeA) declaration within seven days before landing, at arrival.gov.kh or via the official app. It folds immigration, health and customs into one digital form. It is free — any site charging for it is not the government. Do it on the plane or at the gate if you forgot; you cannot clear immigration without it.

Cambodia runs its own visa and arrival system, full stop — there is no third-country pre-clearance or regional waiver scheme to factor in.

🚌 Getting from SAI to Siem Reap: Shuttle, Taxi, Minivan & Tuk-Tuk

This is the part that catches people out. The airport is about 50 km east of town and a similar distance from Angkor Wat. The drive is 55 minutes to about 90 minutes depending on traffic. The old REP airport was a 15-minute tuk-tuk from your guesthouse; SAI is a committed road journey. Budget for it in both time and money.

Official airport shuttle bus. The cheapest fixed-price option is the airport shuttle at US$9 one-way (about US$15 if you buy a round trip on arrival for a later departure). It runs roughly nine times a day into town, with departures spread across the afternoon and evening to meet inbound banks (the published timetable shifts, so confirm the current schedule on arrival). It drops at a central point in town rather than your door — fine if you are travelling light, less so with a stack of luggage and an out-of-centre hotel.

Taxi / private transfer. A pre-booked car or airport taxi runs about US$25–35 for one to three passengers, door to door. This is the default for most visitors and the only sane choice late at night. Arrange it through your hotel or a booking platform before you land so a name-board is waiting; that sidesteps the unmarked-car touts in the arrivals hall who quote a “special price” and then renegotiate at the kerb.

Shared minivan. Shared minivans run roughly 49,000 KHR (about US$12) per seat and take around an hour, leaving when full. Cheaper than a private car, slower than the shuttle if it sits waiting for passengers.

Tuk-tuk. Tuk-tuks do make the airport run, typically 60,000–100,000 KHR (about US$15–25) for up to four people, but 50 km in an open three-wheeler is a long, dusty, hot ride and not faster than a car. Fine for the adventure; not for arriving fresh.

Ride-hailing. The Grab and PassApp apps work in Siem Reap and price the trip from around 100,000 KHR (about US$25) for four. The app price is metered and visible before you confirm, which is its main advantage over haggling at the rank.

There is no rail link to the airport and none is planned.

🛋️ The Angkor Lounge: One Lounge, Two Networks

SAI has one independent pay-or-membership lounge worth naming: the Angkor Lounge, airside in International Departures on Level 3, near gates 1–3 past the duty-free run. It is on both the Priority Pass and DragonPass networks, so a card from either gets you in; pay-per-use entry is also available if you hold neither. Published hours are 06:00–21:00 daily, with a four-hour maximum stay per visit. It offers the standard kit — seating, air conditioning, hot and cold food, alcoholic and soft drinks, wifi and flight-information screens.

A note on stale listings: some lounge directories still show a Plaza Premium entry under the old REP code. That was the downtown airport, now closed to commercial flights. Treat any Plaza Premium reference for Siem Reap with suspicion and confirm at the airport before relying on it; the lounge this guide can verify at SAI today is the Angkor Lounge.

🍚 Eating at SAI & the Food Waiting in Town

The terminal has the usual airside cafés and a duty-free zone; expect coffee, noodle and rice dishes, sandwiches and packaged snacks, priced in US dollars and at airport rather than street rates. It is functional rather than a reason to arrive early. If you have a long wait, the Angkor Lounge food is the better value once you are inside.

The food worth planning for is in town, an hour away. Siem Reap’s Khmer kitchen is its own thing, not a milder Thai. Fish amok — a coconut-and-lemongrass fish curry steamed soft in a banana-leaf cup, thickened with kroeung spice paste — is the dish to try first. Lok lak, stir-fried beef over rice with a lime-and-Kampot-pepper dip, is the everyday plate locals actually order. Kampot pepper itself, grown on Cambodia’s south coast, is a genuine regional product and turns up in better kitchens. The night-market and Pub Street area near the Old Market (Psar Chas) is where most visitors eat; for less of a tourist mark-up, the local restaurants a few streets back from the river charge in riel and in dollars and cost a fraction of the Pub Street boards.

💡 Layover Reality: A 50 km Airport and Whether Angkor Is Reachable

Be honest with yourself about the geography. SAI is roughly 50 km from town and 51 km from Angkor Wat. A round trip to the temples is two to three hours of driving alone, before you add the international return-check-in and security buffer — plan on being back airside at least 90 minutes to two hours before your onward flight, more at peak. That is the math that governs everything below.

Under 6 hours: stay airside. By the time you cleared immigration, found a car, drove an hour, and turned straight around, you would be racing back. The Angkor Lounge or the terminal cafés are the realistic use of the time.

6–8 hours: still tight. You could reach town for a meal and turn around, but Angkor Wat itself is not a sensible target. The Angkor Archaeological Park needs a ticket and a full circuit; an hour at the temple is not what you flew for, and the transfer eats the rest.

12 hours or more, daytime: now a quick temple touch becomes possible with a private car arranged in advance. Even then, you must buy an Angkor pass — the 1-day pass is US$37 (2026 rate), sold by Angkor Enterprise online, at its main office on Road 60, or at self-service kiosks. One useful rule: a pass bought after about 5pm is valid for the same evening’s sunset and the following day, so an evening-arrival layover can catch sunset at a temple like Phnom Bakheng and still have the pass live the next morning. For a genuine first visit to Angkor Wat — the moat, the causeway, the central towers, the bas-reliefs — give it a full day and an overnight in Siem Reap. A layover is not the way to see it properly.

In short: SAI is not a casual layover airport for Angkor Wat. The temples are the reason to fly here, but they reward a stay, not a connection.

🔧 Practical Notes — Connectivity, Currency, Border

Currency — the dual-currency reality. Cambodia is effectively dollarised. The US dollar is the everyday currency: hotels, taxis, tours, restaurants, the airport shuttle and your visa are all quoted and paid in USD. The Cambodian riel (KHR) functions mainly as small change — at roughly 4,000 KHR to US$1, anything under a dollar comes back to you in riel. Pay for a US$4.50 coffee with a US$5 note and you will get about 2,000 riel in change. Carry clean, unmarked, untorn US dollar notes; vendors and even banks routinely refuse damaged bills, and a torn US$20 can be hard to spend. ATMs dispense both currencies and usually default to dollars. The airport bureau de change exists but applies a tourist-rate markup — change only what you need to leave the terminal, and draw the rest from an ATM in town.

Connectivity. Buy a local SIM or eSIM for data; the main Cambodian operators sell tourist SIMs cheaply and coverage in Siem Reap is solid. Terminal wifi is available but, as everywhere, an eSIM bought before you land is the smoother option.

Border, restated plainly. Cambodia uses its own entry system: an e-Visa or visa on arrival (US$30 tourist), plus the free, mandatory e-Arrival card filed within seven days of travel. No other regional entry scheme applies. Sort the e-Arrival card before you fly so it is not the thing standing between you and the immigration desk.
