Getting from Techo Airport (KTI) to Phnom Penh: Bus, Grab, and Taxi Costs for Americans

Why the ride into Phnom Penh costs more than you expect

If your mental picture of the Phnom Penh airport ride comes from an older guide or a previous trip, reset it. The old airport sat close to the city, a short and cheap hop in. Techo International Airport, code KTI, opened on 9 September 2025 and sits roughly 20 km south of central Phnom Penh. That distance changes everything about the ride in — it is longer, it costs more, and the option you pick matters more than it used to. A few extra dollars and twenty extra minutes is the new baseline, not a rip-off.

The good news is that KTI is a brand-new airport with an organized arrivals hall, so the transport options are clearly laid out rather than a scrum of touts. You can walk the few steps from baggage claim to a SIM counter, an ATM, and a fixed-price taxi desk without leaving the building. The three real choices — express bus, ride-hail app, and fixed-price taxi — each suit a different kind of arrival, and once you know the USD cost and travel time for each, the decision is quick.

This guide breaks down all three options with real USD costs and travel times, then covers how to pay and the mistakes that cost Americans money at the curb. None of it matters, though, if your entry is not sorted, so do that first — 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. Everything at KTI assumes your visa is already approved.

1. 1
   Connect your phone first

   Buy a tourist SIM for a few US dollars at an arrivals-hall telecom counter, or activate an eSIM, so Grab and PassApp work before you walk out.

2. 2
   Grab some cash

   Hit an arrivals-hall ATM and break a few twenties into smaller, clean USD notes — drivers and the taxi desk rarely have change for a large bill.

3. 3
   Pick your channel

   Compare a Grab or PassApp quote ($10–$18 door to door) against the fixed-price taxi desk ($15–$25) or the express bus (a few dollars).

4. 4
   Skip the freelance drivers

   Walk past anyone calling out near the doors and use only the app pickup zone or the marked taxi desk, where the fare is fixed and there is a receipt.

5. 5
   Confirm and ride into the city

   Match the license plate to the app or pay the desk, then settle in for the 35 to 60 minute trip across the roughly 20 km from KTI to central Phnom Penh.

The three ways into Phnom Penh from KTI, compared

There are three realistic ways to cover the 20 km from KTI into central Phnom Penh: the airport express bus, a ride-hail app like Grab or PassApp, and the official fixed-price taxi desk. Each one trades cost against convenience, and the right pick depends on how much luggage you have, whether your phone is connected, what time you land, and how much haggling energy you have left after the flight. Here is what each actually costs in US dollars and how long it takes.

The airport express bus — cheapest

The KTI express bus is the budget option, costing only a few US dollars per person for the run into the city. It follows a set route to central Phnom Penh stops rather than dropping you at your exact door, so it works best if you travel light and your accommodation is near a main stop. The trade-off is time and flexibility: you wait for a departure, you share the ride, and you finish with a short walk or a cheap tuk-tuk to your final address. For a solo traveler with a single carry-on and no rush, it is the best value at the airport.

Grab or PassApp ride-hail — best value for most

A ride-hail car booked through Grab or PassApp is the sweet spot for most American travelers. Expect roughly $10 to $18 USD for a standard car door to door into the city center, with the exact fare shown in the app before you confirm — no negotiation, no surprise at the end. The catch is that you need a live SIM or eSIM and a working data connection to book it, so set that up in the arrivals hall first. The app fare is usually lower than the taxi desk and the car comes to you, which is why it is the default choice once your phone is online.

Fixed-price taxi desk — simplest

The official taxi desk inside the arrivals hall sells a fixed-price ride into Phnom Penh for roughly $15 to $25 USD depending on the part of the city and the vehicle size. You pay a set fare at the counter, get a receipt, and a driver takes you straight to your address with no app, no data, and no haggling. It costs a few dollars more than a Grab, but it is the simplest option when you land late, your phone is dead, or you just want to hand over cash and be driven without thinking. Avoid the freelance drivers calling out near the doors — use the marked desk.

Using Grab and PassApp from KTI: the setup that saves money

Ride-hailing is the cheapest door-to-door option and the one most Americans default to, but it only works if you do one thing first: get your phone connected before you leave the arrivals hall. A booked Grab or PassApp ride shows the fare up front, routes by GPS so the driver cannot pad the trip, and brings the car to a designated airport pickup point. Without data, none of that is available and you are back to negotiating cash with whoever is at the curb.

Buy a tourist SIM at one of the telecom counters in the arrivals hall — a few US dollars for plenty of data, set up on the spot with your passport — or activate an eSIM you bought online before you flew. Either way, get online before you step outside. Our Techo Airport arrival walkthrough for Americans covers the SIM, ATM, and arrivals-hall layout in the order you hit them, so you can plan the connection step before you land.

Grab is the bigger international app and the one most American travelers already have installed; PassApp is the local favorite and often has more cars and slightly lower fares within Phnom Penh. Install both before you fly and compare the quoted fare on each when you land — it takes ten seconds and can save a few dollars. Both show the price in the app and let you pay by card or cash; for arrivals, paying the driver in clean USD cash is the most reliable, since a foreign card occasionally fails to attach on a fresh account.

At KTI, ride-hail cars use a designated pickup zone rather than the main taxi curb, so follow the app map and the airport signage to the right spot — the driver will message you the bay or column number. Watch the fare in the app: $10 to $18 USD to the city center is normal, and a quote far above that usually means surge pricing during a busy arrival bank, in which case waiting fifteen minutes often drops it back down. Confirm the license plate matches the app before you get in, the same as you would at home.

The express bus, the taxi desk, and hotel pickup

If ride-hailing is not your pick — no data, lots of luggage, a group splitting a fare, or you just want it handled — the other three routes into the city each have a clear use case. Here is when each one wins and what to watch for.

The express bus, in practice

The express bus is genuinely cheap and genuinely fine if your situation fits it: light luggage, no tight schedule, and accommodation near a central stop. You buy a ticket at the bus counter or from the driver, load your bag, and ride a set route into the city. The downside is the last mile — the bus drops you at a fixed stop, not your hotel, so you finish with a short tuk-tuk or walk. For solo budget travelers it is the best value leaving KTI; for a jet-lagged family with three suitcases at 1 a.m., it is the wrong tool.

The fixed-price taxi desk, in practice

The marked taxi desk in the arrivals hall is the no-thinking option. You tell the staff your destination, pay a set fare of roughly $15 to $25 USD, and a driver takes you straight there. There is no metering, no haggling, and no app needed, which makes it the right call when you land late, your phone is dead, or you are too tired to fiddle with ride-hailing. If you are touching down after midnight, our guide to a late-night arrival at Techo for Americans walks through which desks stay open and how to get into the city safely. Pay at the desk, not in the car, and keep the receipt. The only thing to avoid is the freelance drivers who approach you before the desk — they quote higher and there is no recourse if something goes wrong.

Pre-arranged hotel pickup

Many Phnom Penh hotels offer an airport pickup, usually in the $15 to $28 USD range, arranged when you book. A driver waits in the arrivals hall with your name on a sign, which is the lowest-stress option of all — no app, no desk, no cash negotiation while jet-lagged. It costs a little more than a Grab, but for a late-night arrival or a first trip to a new city, that premium buys real peace of mind. Confirm the pickup the day before and ask whether the fare reflects the longer run from KTI rather than the old airport, since some listings have not updated.

Paying in USD, and the mistakes that cost Americans money

Cambodia runs on US dollars in daily life, which makes the transport-payment side easy for Americans — you can pay nearly every fare directly in USD bills and skip the currency math. The catch is in the details: which bills are accepted, where the riel fits, and the handful of curb mistakes that quietly cost travelers an extra ten or twenty dollars on the very first ride.

Bring clean, undamaged USD notes — drivers and the taxi desk routinely refuse torn, marked, or pre-2013 bills, and a rejected note at the curb is an awkward way to start the trip. The ATMs in the arrivals hall dispense both US dollars and Cambodian riel; the riel is mainly for small change under a dollar, so you rarely need much. Break a few twenties into smaller notes before you ride, since drivers seldom have change for a large bill. Our guide to airport cash, ATMs, and currency exchange for Americans covers exactly how the dollar-and-riel system works on arrival.

The most expensive mistake is taking a ride from a freelance driver who approaches you in the hall or at the doors before you reach the marked desk or the ride-hail pickup zone. Their opening quote is usually double the real fare, there is no fixed price and no receipt, and a few have a reputation for renegotiating mid-trip. Walk past them to the official taxi desk or to your booked Grab. The marked, fixed-price channels exist precisely so you do not have to argue.

The second trap is assuming the old airport fare still applies. Because KTI is about 20 km out versus the old airport sitting near the city, a price that sounds high may simply be correct for the distance. If you are still oriented around the old terminal, our explainer on why Phnom Penh airport moved to KTI lays out what changed and why every ride now costs more. Knowing the real ranges — a few dollars for the bus, $10 to $18 for a Grab, $15 to $25 for the taxi desk — means you can tell a fair fare from a padded one. Anything wildly above those numbers is the cue to use the app or the desk instead.

The last one is arriving with no connectivity and no small bills, then defaulting to the priciest curbside option out of sheer fatigue. Five minutes in the arrivals hall — buy a SIM, hit an ATM, break a twenty — gives you every cheaper option and removes the pressure to just take whatever is loudest at the doors. Do the boring setup first and the ride sorts itself out.
