Most US flights reach Phnom Penh after dark, often past midnight, after a connection through Asia. Here is how to arrive at Techo International Airport (KTI) late at night and get into the city safely — the pre-booked ride, the fixed-price taxi desk, the cash you need, and the traps to skip when you are tired.
Arrange your ride before you land. The three safe options are a ride-hailing app like Grab or PassApp once your SIM or eSIM is live, the official fixed-price airport taxi desk inside the arrivals hall, or a pre-booked hotel pickup with your name on a sign. All three give you a known driver and a known price, which is what you want at 1 a.m. when you are tired and it is dark. KTI is about 20 km south of central Phnom Penh, so budget 40 minutes or more for the ride and a higher fare than the old airport. Carry small US dollar bills for the fare, since drivers will not have change for large notes late at night. Avoid anyone who approaches you offering a ride before you reach the official desk — that is the one move to skip. Clear Immigration faster by having your approved eVisa and e-Arrival QR code ready before you board.
There are no direct flights from the United States to Phnom Penh. Every American gets there on a connection — through Doha, Seoul, Singapore, Bangkok, Hong Kong, or Taipei — and the last leg into Cambodia is almost always an evening or overnight hop. The math of those long-haul schedules means a huge share of US travelers touch down at Techo International Airport (KTI) after 10 p.m., and plenty land well past midnight. If your itinerary routes you through the Gulf or East Asia, there is a good chance you will be walking out of arrivals into the dark.
A late-night arrival is not dangerous, but it is different. The arrivals hall is quieter, fewer counters are staffed, you are tired from 20-plus hours of travel, and the decisions you make at the curb — which ride, what price, how to pay — are the ones most likely to go sideways when your judgment is dulled. The single best thing you can do is take those decisions off the table before you ever board, so that when you step outside at 1 a.m. the only thing left to do is walk to a ride you already arranged.
This guide is the late-night version of the arrival: the safe transport options, the cash you need, and the traps that catch tired travelers in the dark. It assumes your visa and arrival paperwork are already done — if they are not, start there, because everything below assumes a clean, fast walk through Immigration. When you are ready you can apply for the eVisa in a few minutes, and our Cambodia visa for United States citizens pulls cost, documents, and processing into one reference.
Have your $80 tourist eVisa approved (3 business days) and your $5 e-Arrival Card filed within 7 days before arrival, both saved offline.
Choose one of three: a pre-booked hotel pickup, Grab or PassApp, or the fixed-price airport taxi desk inside arrivals.
Scan your e-Arrival QR first, then clear Immigration with your approved eVisa — both are quick when they are already on your phone.
Activate your eSIM or buy a SIM at the counter, and pull small US dollar bills from the arrivals-hall ATM before you head out.
Go to your hotel driver, your app pickup zone, or the official taxi desk — never a car from someone who approaches you.
KTI sits about 20 km south of central Phnom Penh, so budget 40 minutes or more with the fare agreed before you set off.
A late-night Immigration line is the worst place to discover a problem with your documents. You are exhausted, the desks are running a skeleton crew, and anything that needs fixing on the spot turns a 20-minute walk-through into an hour of standing around. The fix is simple: have everything approved and saved offline before you board, so every checkpoint is a scan, not a form.
The eVisa is your permission to enter Cambodia and it must be approved before you fly. The tourist eVisa is $80 USD all-in and is approved in 3 business days, delivered as a printable PDF by email. Do not leave it to the last minute, and do not assume you can sort it at the airport at midnight — you cannot. Save the PDF to your phone and print a paper backup, because a dying battery after a long-haul flight is exactly when the officer asks to see it. The eVisa is valid for 3 months from issue and gives you a 30-day, single-entry stay.
The e-Arrival Card is a separate, mandatory step for every air arrival — 14 fields you file within the 7 days before your flight. Once submitted it returns a QR code, and that QR code is the very first thing scanned at KTI, before you even reach Immigration. We file a verified e-Arrival Card for $5 USD, checked end-to-end before it reaches Cambodian Immigration, so a date-format slip does not get you pulled aside at the kiosk at 1 a.m. Screenshot the QR confirmation so it lives offline on your phone. For the full gate-to-taxi sequence in daylight terms, our Techo airport arrival walkthrough for Americans lays out all six steps in order.
The 2 a.m. battery test
Before you board your final leg, screenshot your eVisa PDF and your e-Arrival QR so both load with zero signal and a near-dead battery. Late-night arrivals are when airport Wi-Fi is flaky and your phone is at 6 percent — offline copies turn both checkpoints into two-second scans.
You have three realistic, safe options for the ride into the city, and all three share one feature: a known driver and a known price agreed before you move. That is the whole game at a late-night arrival. Pick one before you fly and you walk out of the doors with a plan instead of a negotiation. KTI is about 20 km south of central Phnom Penh, so whichever you choose, the ride is 40 minutes or more and the fare is higher than older guides quote for the old airport.
For a midnight arrival, a hotel pickup is the calmest option there is. You email your hotel or guesthouse your flight number and arrival time a day or two ahead, and a driver waits inside the arrivals hall with your name on a sign. The price is fixed and known in advance, the driver knows exactly where you are going, and there is zero negotiating at the curb when you are barely awake. It usually costs a little more than a ride-hailing fare, and for a first night in an unfamiliar city in the dark, most American travelers find it well worth it.
Grab and PassApp both work at KTI and run through the night. Once your SIM or eSIM is live, you open the app, set the pickup to the airport and the drop to your hotel, and the price is shown and locked before you confirm — no haggling, no meter surprises, and a digital record of the driver and car. The catch at a late-night arrival is that you need data first, so set up your eSIM before you fly or buy a SIM at the arrivals counter before you walk outside. KTI has a designated ride-hailing pickup zone; follow the app map and the signage to it rather than getting into a car that pulls up randomly.
Inside the arrivals hall there is an official taxi desk with fixed, posted fares into the city by zone. You pay or confirm the price at the desk, they assign you a marked car, and you go — no roadside price negotiation. This is the reliable fallback if your phone died, your eSIM will not activate, or you simply do not want to fuss with an app at 1 a.m. It costs a bit more than ride-hailing but it is fixed and legitimate. Our Techo airport to Phnom Penh transport and cost guide breaks down what each of these three options actually costs so you can budget the fare before you land.
Whatever ride you choose, two things make a late-night arrival smooth: a working phone and the right cash. Both take five minutes in the arrivals hall, and both are far easier to sort inside under the lights than outside in the dark with a driver waiting. Resist the urge to bolt straight for the exit because you are tired — the five minutes you spend here saves you the headache outside.
Cambodia runs on US dollars day to day, which makes life easy for American travelers — but only if your bills are the right size. A driver at 1 a.m. is not going to have change for a $100 bill, and handing over a fifty for a twenty-something-dollar fare is asking to be told there is no change. Before you fly, break a couple hundred dollars into fives, tens, and twenties. Bring clean, undamaged notes too, because torn or heavily marked bills are sometimes refused. The airport ATMs dispense both US dollars and Cambodian riel, with riel used mainly for change under a dollar.
You need data to run Grab or PassApp, message your hotel, or pull up a map, so get connected before you walk outside. The telecom counters in the arrivals hall sell tourist SIMs with plenty of data for a few US dollars and set them up on the spot — bring your passport, since SIMs are registered to it. The easier late-night move is an eSIM you buy online before you fly and activate the moment you land, which skips the counter entirely while it is being wound down for the night. Our guide to cash, ATMs, and currency exchange at Cambodia airports covers exactly what to withdraw and what the machines hand out.
One small thing that matters more at night: tell someone your plan. Drop your hotel a message that you have landed and are on your way, or share your ride in the Grab app with someone back home. It costs nothing, and a tired solo traveler heading into an unfamiliar city in the dark is exactly the moment a shared trip and a quick check-in message earn their keep.
Almost nothing goes wrong at a Cambodian airport at night, but the things that do go wrong are predictable and easy to avoid once you know them. Every one of them comes down to making a transport decision while exhausted, in the dark, without a plan. Here are the traps, and the simple move that skips each one.
The first and most common is taking a ride from someone who approaches you. Anyone who walks up to you inside or just outside the terminal offering a taxi, a great deal, or a free ride is not the official taxi desk and is not your hotel driver. The move is to ignore the offer, walk to the official taxi desk or your app pickup zone, and use a ride with a known price. A driver with your name on a sign or a car you booked in an app is the only ride you should get into.
The second is getting in without agreeing the price. If you use the official desk or an app, the price is fixed for you. If for any reason you are negotiating directly with a driver — which you should not need to do — settle the full fare to your exact destination before you put a bag in the trunk, never after. "We sort it later" is how a tired traveler ends up arguing about money on a dark roadside, and it is entirely avoidable.
The third is underestimating the ride. KTI is about 20 km south of the city, so a 40-minute-plus drive in the dark is normal — that is the airport being far out, not your driver taking you the long way. Have your hotel address written down in English and, ideally, the Khmer name or a map pin saved offline, so you are not relying on a tired memory of how to pronounce it. For what to expect at the desk itself in the small hours, our guide to how long immigration takes at Techo Airport covers the after-dark version of the checkpoint.
A fourth trap is purely a travel-planning one: do not assume you can cross in from Thailand by land if your flight is awkward. All seven Thailand–Cambodia land borders have been closed since June 2025, so the overland route from Bangkok is not a fallback — flying into KTI is the way in. And remember the tourist visa auto-extension ended in November 2025, so your 30-day single-entry stay has no automatic grace period at the back end. Plan your departure inside the 30 days.
