🏢 1. The Terminal & the Carriers That Actually Fly Here

Techo opened to commercial traffic on 9 September 2025, when Air Cambodia flight K6611 from Guangzhou became the first arrival. The official inauguration followed on 20 October 2025. From that switchover date, every airline that had served the old PNH field at Pochentong moved its Phnom Penh operation here; the old airport kept the PNH code on paper but lost the planes.

The terminal is a single building designed by Foster + Partners: a central head house flanked by two long piers. There is no second terminal to get lost between, and no inter-terminal shuttle to time — a structural simplicity that works in a connecting passenger’s favour. Phase 1 is rated for around 13 million passengers a year, with later phases planned to push that toward 30 million and eventually higher. Because the airport is new, some retail and dining units were still fitting out through early 2026; treat any specific shop or counter as “verify on the day.”

KTI is run as a fully digital, common-use airport on SITA systems, which is why so many carriers were able to plug in from day one. Air Cambodia (K6), Cambodia Airways (KR) and Sky Angkor Airlines base their operations here, and Vietnam Airlines treats it as a focus city. On the international side the carrier list as of early 2026 includes AirAsia and Thai AirAsia, Bangkok Airways, Thai Airways, Malaysia Airlines, Vietnam Airlines, Singapore-region and Chinese carriers including Air China, plus longer-haul names such as Qatar Airways, Emirates, Korean Air, Cathay Pacific and EVA Air feeding the big one-stop connections. The densest links are short regional hops — Bangkok and Guangzhou run the most frequent flights. Confirm your specific carrier’s KTI operation at booking, since a few airlines published their move dates separately during the 2025 transition.

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

Cambodia runs its own entry system. Nothing about the EU, North American, or any other region’s pre-clearance scheme applies here; the rules below are the whole picture for a tourist arriving by air, verified for 2026.

You need a visa unless you hold an exempt passport. The standard tourist visa (the T-class) costs US$30 and grants a 30-day stay, extendable once for another 30 days at an immigration office inside the country. There are two ways to get it:

• e-Visa, applied for in advance at the official portal evisa.gov.kh. You upload a passport scan and photo, pay the US$30 online, and processing typically takes around three business days. Apply only through the official .gov.kh site — lookalike commercial sites charge a markup for the same document.
• Visa on Arrival at the airport, also US$30, paid in cash on the day. Bring clean US dollar notes; the counter is a cash transaction and is not the place to be hunting for an ATM.

ASEAN nationals (Thailand, Vietnam, Laos, Malaysia, Singapore, Indonesia, the Philippines and the rest of the bloc) enter visa-free, with the permitted stay running roughly 14 to 30 days depending on nationality. Check your own country’s exact allowance before flying rather than assuming the longer figure.

Separately from the visa, every air arrival must complete the Cambodia e-Arrival card. It is free, it is filed online within the seven days before you land, and it bundles the immigration, customs and health declarations into one digital submission. Do it before you reach the airport — having the QR confirmation ready speeds the desk, and Techo was built around this digital-first flow. Your passport needs at least six months’ validity beyond your entry date.

🚌 3. Getting Into the City: Express Bus, Taxi & Ride-Hailing

Techo sits roughly 20 km south of central Phnom Penh. Without traffic the drive is about 50 minutes; in the city’s rush windows (mornings, the lunch hour, and the early evening) it can stretch well past that.

Airport Express Bus — cheapest by a wide margin. A one-way ticket is 1,500 KHR (about US$0.37) as of December 2025, paid in cash into a drop-box on board. This is the one situation where you genuinely need small riel notes rather than dollars — the box does not make change and does not take cards or the local WingPay wallet. The route ends at the Kouch Cannon Roundabout bus station near the French Embassy, with stops along the way including Canadia Park and the Royal University of Law and Economics. Buses run frequently across the day, roughly from early morning to late evening; total time into the centre is around an hour and a quarter, longer in traffic. Confirm the current fare and first/last departures before you rely on it, since this is a new operation still settling its timetable.

Taxi. Metered and fixed-rate airport taxis to the city start at roughly US$25–35 depending on your exact destination and the traffic. Use the official taxi desk inside the terminal rather than accepting an offer from someone who approaches you in the hall — the unmarked-car approach in the arrivals area is the standard overcharge here, and agreeing a price before the doors close is the only protection.

Ride-hailing. Grab and the local apps PassApp, WowNow and Move all operate at KTI, with a car into town running around US$16, more in rush hours. The app price is fixed up front, which sidesteps the haggling, but you have to find the designated pickup zone — follow the airport’s ride-hail signage rather than the taxi rank.

There is no rail link to the airport and none under construction at the time of writing.

🛋️ 4. Lounges: Which Card Opens Which Door

Techo’s lounge provision is run by Plaza Premium, airside on Level 3, and the access rules differ sharply between the two rooms.

Plaza Premium Lounge is the one most travellers will use. It admits Priority Pass and DragonPass members, with a two-hour maximum stay on those memberships, and sells a walk-up day pass online or at the door. Hours run roughly 06:00 to midnight daily. The offering is the standard Plaza Premium spread — buffet, bar with standard pours, showers and quiet seating. LoungeKey acceptance is not listed among the membership programs as of early 2026; if you hold a LoungeKey-only card, plan to pay the day rate rather than counting on free entry.

Plaza Premium First is the upper-tier room and does not accept Priority Pass or DragonPass at all — it is for eligible premium-cabin and first-class passengers and paid bookings only. Don’t queue here expecting your lounge card to work.

If you hold neither membership and don’t want to pay, the terminal’s regular seating and food court are the alternative; on a new, low-density airport the gate areas are not yet the crush you’d find at an older Southeast Asian hub.

🍜 5. Eating at the Airport & First Khmer Food in Town

Because Techo is barely a year into operation, its food and retail were still filling out through early 2026, so treat any named outlet as something to confirm on the concourse rather than plan around. Expect the standard new-airport mix: a food court with Khmer and pan-Asian counters, a couple of coffee chains, and convenience units landside and airside. Prices are quoted in dollars, padded above town rates as airports everywhere do.

The Khmer dish worth saving your appetite for is kuy teav — a pork-and-rice-noodle breakfast soup, served with a plate of herbs and lime you add yourself — and amok, fish steamed in coconut and kroeung spice paste, usually in a banana-leaf cup. Neither travels well as airport food; both are better an hour later in town. If you have a long enough layover to leave (see the next section), the noodle stalls and riverside spots around the Sisowath Quay and the Central Market (Phsar Thmei) are the obvious first stop. For a fast bite inside the terminal, a bowl of noodle soup and a Cambodian iced coffee — strong, sweet, condensed-milk-heavy — is the honest order.

💡 6. Layover Reality: 20 km South and What That Buys You

Do the round-trip arithmetic before you decide to leave the airport on a connection. Central Phnom Penh is about 20 km away, roughly 50 minutes each way without traffic and meaningfully more in it. That is a 40 km, near-two-hour round trip on the road before you account for the return: you want to be back through security with margin, and on an international connection a two-hour pre-departure buffer is the sane minimum. Add it up and a city run costs you something like four hours of overhead, conservatively, before you’ve seen anything.

The practical thresholds:

• Under 6 hours: stay airside. By the time you clear immigration (you’d need a visa to leave the airport), ride 50 minutes in, see one thing, and ride 50 minutes back, you’re racing your own boarding call. The lounge or a noodle bowl is the better use of the gap.
• 6 to 8 hours: a tight single-target run is possible if you already hold a visa and traffic cooperates — the Royal Palace and Silver Pagoda complex, or the riverside at Sisowath Quay, are the closest meaningful sights. The Tuol Sleng Genocide Museum (S-21) and the Choeung Ek killing fields are reachable but are heavy, deliberate visits that don’t suit a clock-watching dash, and Choeung Ek is a further 15 km south-west of the centre — verify you have the hours before committing.
• 8 hours or more, visa in hand: a genuine half-day in the city works. Even then, build the return around traffic, not optimism.

If your layover is short and you have no visa, the question answers itself: you stay airside, and the city waits for a real trip.

🔧 Practical Notes — Connectivity, Currency, Border

Currency — the dual-money reality. This is the thing that trips up first-time visitors. The official currency is the Cambodian riel (KHR), but the US dollar is what daily life actually runs on. Taxis, hotels, restaurants, the airport’s own shops and most market stalls quote and accept dollars; the riel functions mainly as small change for amounts under a dollar. In practice you pay a US$4.50 bill with a five-dollar note and get your roughly 2,000 KHR change back in riel, because there are no US coins in circulation. The conversion locals use is round: about 4,000 riel to the dollar (the market rate sat near 4,030 KHR/USD in May 2026 — verify before travel).

Two consequences. First, carry clean, untorn US dollar bills — Cambodian vendors and the visa counter reject damaged or heavily marked notes. Second, the one fare that demands actual riel is the airport express bus, so peel off a few small riel notes when you change money or take change in town. Avoid changing large sums at the airport bureau de change, where the markup is worse than at a city exchange or a bank ATM; pull a modest amount for the bus and first taxi, then sort the rest in town.

Connectivity. Techo is built as a fully digital airport, with terminal Wi-Fi and the e-Arrival/e-Visa flow assuming you’ll arrive already processed online. A local SIM or eSIM (Cellcard, Smart, Metfone are the main networks) is cheap and worth buying for the Grab apps and maps; SIM counters are the usual airport-arrivals proposition, so compare against a city shop if you’re price-sensitive.

Border, restated plainly. Get the e-Arrival card filed within seven days before you fly, hold either an e-Visa from evisa.gov.kh or US$30 cash for Visa on Arrival, and carry a passport valid six months out. That is the entire entry checklist for a tourist arriving by air. No regional pre-clearance program, EU or otherwise, has any bearing on a Cambodia arrival.
