Phnom Penh’s New Airport: What Changed After Techo Opened

Prepared by the NovAsia Editorial Team

Techo International Airport has handled Phnom Penh’s main commercial flights since 9 September 2025, replacing the former Phnom Penh International Airport as the capital’s primary passenger hub. It lies approximately 20 kilometres south of central Phnom Penh in Kandal province. The biggest practical change for most passengers is therefore not only the new terminal, but a longer and less predictable ground journey from many parts of the city.

The new airport uses the IATA code KTI and the ICAO code VDTI. The old code PNH belongs to the former airport and should no longer be used automatically when arranging a transfer. Before every trip, check the airport name, terminal location and actual departure point shown on the booking.

What opened in September 2025?

Techo International Airport became the new principal international aviation hub for the Phnom Penh metropolitan area. The first phase is already operational and includes the main passenger terminal, one runway, taxiways, apron space and facilities for domestic and international flights.

This was a completely new airport built on a separate site rather than an extension of the previous terminal. Passengers now deal with:

• a different airport code;
• a different route out of the city;
• a new terminal;
• new check-in and arrivals areas;
• different taxi and parking arrangements;
• new meeting points;
• a much larger site reserved for future expansion.

Commercial operations began on 9 September 2025. A formal inauguration ceremony followed on 20 October 2025. These dates are sometimes mixed together, but the first matters most to passengers because that is when major airline operations moved to Techo.

Where is Techo International Airport?

The airport is in Ta Prohm village, Boeng Khyang commune, Kandal Stueng district, Kandal province. The official airport website places it around 20 kilometres south of central Phnom Penh.

A straight-line distance or a distance measured from an undefined “city centre” does not describe the real journey. Different parts of Phnom Penh have very different access.

Areas usually better positioned for KTI include:

• southern Phnom Penh;
• the Hun Sen Boulevard corridor;
• Meanchey;
• areas around AEON Mall Mean Chey;
• Takhmao;
• parts of Kandal province.

The journey is generally longer and more complex from:

• Sen Sok;
• Toul Kork;
• Russey Keo;
• Chroy Changvar;
• northern and north-western outskirts;
• locations that require crossing bridges or major junctions.

The statement “the airport is 20 kilometres from the city” should never be converted into one universal journey time. The complete route from the specific home or hotel to the drop-off area is what matters.

How the road route from Phnom Penh works

Official access information directs traffic through the southern road network and Samdach Hun Sen Boulevard. Airport materials refer to travel through the Morodok Techo interchange and the Samdech Thipadei Hun Manet overpass before following signs to the terminal.

For most passengers, journey time depends on how quickly they can reach the southern transport corridor.

The slowest section may occur well before the final airport approach because of:

• traffic leaving the residential neighbourhood;
• congested junctions;
• school traffic;
• bridge queues;
• the evening rush hour;
• heavy rain;
• public holidays and major events.

The final airport road can be straightforward while one slow section inside Phnom Penh substantially increases the total journey.

How much time should you allow?

There is no single official travel time that applies to every district, hour and weather condition.

A practical approach is to plan for three different situations:

For a first departure from Techo, it is sensible to test the route in advance or at least check it on the same weekday and at a similar time.

Allow extra caution when:

• the flight is early in the morning;
• you live in northern Phnom Penh;
• you are travelling with a child;
• there is substantial luggage;
• the trip falls in the rainy season;
• departure is during a public holiday;
• additional visa or document checks may be required;
• the ticket is difficult or expensive to change.

A common mistake is to check the journey late at night and apply that result to a daytime departure.

Taxis and ride-hailing services

The airport’s official information lists standard taxis and ride-hailing services including Grab, WowNow and PassApp. A general airport-to-city price indication of roughly $10–20 is published, depending on the destination.

This is an estimate, not a fixed fare. The final cost depends on:

• destination district;
• demand;
• congestion;
• vehicle type;
• passenger count;
• time of day;
• luggage;
• pick-up point;
• whether transport is pre-booked.

Before confirming a vehicle, check:

• the airport is Techo International Airport;
• any terminal or meeting-point instructions;
• whether the luggage fits;
• whether additional charges apply;
• whether the chosen payment method is accepted.

A standard sedan may be too small for a family with several large suitcases. A larger vehicle or advance transfer is often more reliable.

Meeting an arriving passenger

International and domestic arrivals use the lower terminal level. After immigration and baggage reclaim, passengers enter the meeting and ground-transport area.

To avoid searching around a large new building, agree in advance:

• the exact exit or meeting point;
• who waits inside;
• who waits with the vehicle;
• which telephone number will be used;
• what to do if mobile data fails;
• which app or transfer company is handling the journey.

Sending a driver only the word airport is not enough. Use the full name Techo International Airport or an official saved map point.

A person collecting someone from the city should not necessarily arrive too early. Immigration and baggage reclaim can vary considerably, while long waiting directly beside the kerb may be inconvenient or restricted.

Is public transport available?

As of June 2026, passengers should plan primarily around taxis, ride-hailing services, private transfers, rental cars and other road transport. A dedicated rail connection to the terminal is not operational.

Rail or light-rail links between Phnom Penh and the airport have been discussed and appear in government transport planning. The Ministry of Public Works and Transport has included such a connection among medium-term projects.

A planned project is not an operating service. Passengers cannot rely on a future train until:

• construction is complete;
• an opening date is confirmed;
• a timetable is published;
• stations are operating;
• passenger services have actually started.

Property marketing that refers to a “future airport rail line” describes a possibility, not current transport access.

Parking and travelling in your own car

The airport guide indicates close to 2,000 parking spaces for cars and motorcycles near the terminal.

Before driving yourself, confirm:

• the current entrance;
• the correct parking zone;
• tariffs;
• payment method;
• operating hours;
• long-stay rules;
• where to collect the vehicle after arrival.

Do not leave a car in a random passenger drop-off area. The forecourt is designed for traffic circulation and short stops, not extended waiting.

For a rental car, ask the company in advance:

• whether airport return is permitted;
• the designated return point;
• who inspects the vehicle;
• what happens for a night flight;
• whether parking fees are included.

What is inside the terminal?

The terminal separates passenger flows across several levels.

The first level includes:

• international arrivals;
• domestic arrivals;
• baggage reclaim;
• customs;
• meeting areas;
• selected retail and service points;
• access to ground transport.

The second level includes:

• international check-in;
• domestic check-in;
• security screening;
• immigration;
• boarding gates;
• shops and cafes after security;
• premium waiting facilities.

The third level contains additional food, beverage and commercial space.

This arrangement is more spacious than the former airport, but walking distances can also be longer. Passengers with reduced mobility, older travellers and families with small children should request assistance in advance where needed.

Check-in, immigration and connections

Domestic and international flows are served within the same terminal complex but through separate processing areas.

Passengers should follow airline rules rather than relying only on a general airport recommendation. Check-in closing time can depend on:

• domestic or international travel;
• airline;
• checked baggage;
• destination;
• visa verification;
• group travel;
• special documents.

A self-transfer between two separate tickets requires a generous buffer. Even in one terminal, the passenger may need to:

• pass immigration;
• collect baggage;
• clear customs;
• check in again;
• recheck baggage;
• pass security again.

A transfer sign in the terminal does not guarantee a protected connection between any two independently booked flights.

Why the KTI code matters

Techo International Airport uses the IATA code KTI. The former Phnom Penh airport was commonly identified as PNH.

Old habits and saved information can still create problems:

• a driver goes to the former terminal;
• an old article gives the PNH location;
• a saved map link opens the wrong part of the city;
• a transfer template contains the old address;
• a visitor writes only “Phnom Penh Airport”.

Before travelling, verify three things together:

1. The name Techo International Airport.
2. The code KTI.
3. The location south of Phnom Penh in Kandal province.

This is especially important when using a small transfer company or private driver.

What happened to the former Phnom Penh airport?

Techo replaced Phnom Penh International Airport as the capital’s principal commercial passenger airport. VINCI Airports explicitly describes the new airport as the replacement for the former Phnom Penh facility.

The old terminal lies on the western side of the city and was much closer to some residential districts. For residents of Sen Sok, Toul Kork and the north-west, moving passenger operations to Techo increased ground-transfer time and cost.

The former airport should not be treated as a backup passenger terminal by habit. The booking and actual airline schedule determine where a flight operates.

Possible future uses of the old site remain subject to government and aviation decisions. They do not change the current need to travel to KTI for the capital’s main commercial flights.

Why the old airport was no longer sufficient

The former airport was surrounded by urban development and operated with a single runway. Expansion was constrained by housing, roads and city density.

Techo was built with a much larger land reserve of around 2,600 hectares. Its 4F classification allows it to handle large aircraft and gives the infrastructure the technical ability to support longer-haul routes where commercial demand exists.

Technical capability does not automatically create a new direct flight. A route also requires:

• sufficient passenger demand;
• an airline decision;
• traffic rights;
• commercially viable frequency;
• suitable aircraft;
• agreements and operating arrangements;
• a workable connecting network.

The airport creates the capacity for future routes; it does not guarantee any particular destination.

Capacity and expansion phases

The development is structured in three phases.

Official and project materials broadly agree on the following direction:

• Phase 1 is operating;
• Phase 2 provides for another runway and terminal expansion;
• Phase 3 is intended to bring the airport to its final large-scale configuration.

Different sources describe Phase 1 capacity as 13 million or 15 million passengers per year. The difference may reflect design, operational or rounded figures. Readers should therefore avoid treating one number as the only uncontested figure.

Later phases have been described with indicative capacities of around 30 million and eventually 50 million passengers per year. These are design capacities, not the current passenger volume and not a guarantee that those levels will be reached by a fixed date.

Expansion will depend on:

• aviation-market growth;
• route development;
• tourism;
• business travel;
• investment;
• government and operator decisions;
• financing of later phases.

Who developed and operates the airport?

The project is being developed by Cambodia Airport Investment Co., a joint venture established with participation from the State Secretariat of Civil Aviation and OCIC.

International firms have taken part in different components. Foster + Partners designed the architectural concept. VINCI Airports, Lagardère Travel Retail, Newrest and other partners are involved in operational and commercial functions.

This demonstrates the scale and international structure of the project, but it does not guarantee that every service will operate perfectly from the beginning. A new airport normally passes through an adjustment period in which:

• processes change;
• passengers learn the route;
• pick-up points are refined;
• commercial facilities expand;
• signs and navigation are updated;
• airlines adjust their operations.

Current information should therefore be checked before each journey, even if you used the terminal several months earlier.

What services are available?

The official airport site lists:

• domestic and international check-in;
• baggage reclaim;
• shops;
• cafes and restaurants;
• ATMs and foreign exchange;
• lounges;
• passenger assistance;
• Fast Track services;
• car rental;
• taxis;
• lost property;
• a digital map;
• a mobile application.

Not every service necessarily operates around the clock. For a late-night or early-morning flight, do not assume that every restaurant, exchange counter or shop will be open.

Carry:

• a working bank card;
• some cash;
• mobile connectivity;
• drinking water where permitted;
• a charged phone;
• the address of your accommodation;
• transfer confirmation.

Fast Track and special assistance

The airport offers paid Fast Track support for departure, arrival and transfers. Official conditions indicate that advance booking is required, with at least 72 hours recommended, and payment may be available by cash, card or KHQR.

The service may be useful for:

• older travellers;
• families with children;
• first-time visitors to Cambodia;
• business travellers;
• passengers with a short official connection;
• anyone needing support with baggage and orientation.

Fast Track does not override immigration, customs or airline requirements. It helps the passenger navigate the process; it does not create a right of entry or boarding.

Passengers with disabilities or reduced mobility should coordinate assistance with both the airline and airport.

How the new airport changed life for Phnom Penh residents

The effect differs by district.

Southern areas gained an access advantage

Residents in the south of Phnom Penh and Takhmao now have a shorter route to the main airport. This can matter for:

• frequent business travellers;
• aviation workers;
• hotels and transfer companies;
• logistics;
• passenger services;
• families regularly receiving visitors.

Northern districts lost their former proximity

For Sen Sok, Toul Kork, Russey Keo and parts of the north-west, the airport journey became longer. Someone flying a few times a year should not necessarily choose housing around this factor alone. For airline crew, airport staff or very frequent travellers, the difference can be substantial.

Central Phnom Penh did not automatically become impractical

Most residents travel to work, school, shops and clinics far more often than they go to the airport.

Living near KTI is therefore a strong criterion only when aviation travel or airport employment forms a significant part of everyday life.

What KTI means for southern Phnom Penh and Kandal

The opening strengthens the importance of the southern corridor. Around a major transport hub, development naturally includes:

• hotels;
• logistics;
• car rental;
• food services;
• warehouses;
• commercial units;
• employee housing;
• service businesses;
• road infrastructure.

Project materials also refer to extensive adjoining land intended for economic, logistics, industrial, commercial and residential development.

This should not be converted directly into a promise that every nearby plot or apartment will rise in value.

Two properties marketed as “near the airport” may differ completely:

• one has direct road access;
• another sits behind a poor local road;
• one has operating shops and services;
• another is surrounded by empty land;
• one suits airport workers;
• another is inconvenient for daily living;
• one has verified legal documentation;
• another is sold mainly on future infrastructure promises.

The airport is a major infrastructure factor, not proof of investment quality on its own.

Is it worth living near the airport?

Living near KTI may be logical for someone who:

• works at the airport;
• works in logistics;
• flies very frequently;
• operates a hotel or transport business;
• has daily commitments in the southern corridor;
• has little dependence on central Phnom Penh.

It may be inconvenient when:

• a child attends school in the centre;
• work is in northern Phnom Penh;
• major central hospitals are important;
• most social life is in BKK1 or Daun Penh;
• there is no private transport;
• surrounding shops and services are still limited.

Before renting or buying, assess an ordinary working week rather than only the journey to the terminal.

How to assess an area near KTI

A minimum test should include:

1. A morning journey into Phnom Penh.
2. An evening return.
3. A route check after rain.
4. A visit to a supermarket and pharmacy.
5. Testing mobile and home internet.
6. A journey to school or work.
7. Checking street lighting at night.
8. Assessing aircraft and road noise.

Aircraft can be heard beyond the immediate flight path. Noise depends on runway direction, weather, altitude, building construction and operating patterns.

Do not judge it from one daytime viewing. Visit more than once and speak to current residents.

Does a new airport automatically increase property values?

A large airport creates economic activity, but the benefit is distributed unevenly.

Properties may benefit when they are genuinely useful to:

• employees;
• hospitality businesses;
• logistics operators;
• transport companies;
• tenants working in the southern corridor;
• businesses with demonstrable demand.

Risk is higher where a property is sold only on the statement “a few minutes from the airport” but lacks:

• a good access road;
• completed local infrastructure;
• a clear target tenant;
• verified legal status;
• stable management;
• realistic rental demand.

The opening of the airport is a confirmed fact. Future growth in the price of a specific property is a forecast and cannot be treated as guaranteed.

Preparing for your first departure from KTI

The day before travel:

• confirm the KTI code;
• check the flight status;
• verify the terminal and airline instructions;
• save the official address;
• book a suitable vehicle;
• check luggage volume;
• build in a traffic buffer;
• charge your phone;
• save the ticket offline;
• prepare visa and travel documents.

On the day:

• check traffic again;
• do not switch to a smaller vehicle when luggage is substantial;
• confirm the driver is heading to Techo rather than the former airport;
• follow the airline’s arrival-time guidance;
• allow time to navigate the new terminal.

After arrival:

• connect to mobile service;
• go to the agreed meeting point;
• verify the vehicle registration;
• do not hand luggage to an unidentified person;
• confirm the fare when using a taxi outside an app.

Common passenger mistakes

Using PNH by habit

KTI is now the relevant code for Phnom Penh’s main passenger airport.

Allowing the same time as for the old airport

The former terminal was in another part of the city and was much closer to the north-west.

Assuming 20 kilometres means a short journey

Traffic and the starting district matter more than the simple distance.

Relying on a future train

Rail access is under discussion but is not an operating passenger service.

Ordering a vehicle that is too small

Passenger numbers and luggage should be stated in advance.

Buying property only because it is near the airport on a map

Daily infrastructure and the real access road matter more than a marketing radius.

Confusing design capacity with passenger volume

Terminal capacity describes technical potential, not the number of passengers using the airport today.

What to check before every flight

Aviation information changes faster than a general city guide. Before travelling, confirm:

• departure airport;
• code;
• airline;
• time;
• status;
• check-in rules;
• baggage allowance;
• visa requirements;
• road conditions;
• drop-off point;
• return transport.

The official KTI site provides flight information, terminal maps, transport details and contacts. The airline still makes the final decision on flight operation and check-in, so both sources should be checked.

Conclusion

Techo International Airport has changed Phnom Penh’s aviation geography. The capital now has a large modern terminal with substantial expansion land and the infrastructure to handle more traffic and larger aircraft. Passengers, however, must plan the ground journey more carefully, especially from northern and central districts.

The essential rules are straightforward:

• use the code KTI;
• do not travel to the old PNH location by habit;
• calculate journey time from the specific district;
• use confirmed transport;
• do not rely on a rail link that has not opened;
• separate operating infrastructure from future plans;
• do not treat airport proximity as an automatic advantage for every property.

The new airport is already operating as the capital’s main passenger hub. Future railway connections, later expansion phases and the effect on individual property markets should be assessed as they are actually implemented, not as guaranteed outcomes in promotional material.

Frequently asked

Which airport now serves Phnom Penh?

Phnom Penh’s main commercial flights operate from Techo International Airport, using the code KTI. It opened on 9 September 2025 and replaced the former Phnom Penh airport as the capital’s main passenger hub.

Where is Phnom Penh’s new airport?

It is approximately 20 kilometres south of central Phnom Penh in Kandal Stueng district, Kandal province. Actual journey time depends on the part of the city, traffic and weather.

Is there a train from Phnom Penh to Techo Airport?

There is no operating rail link to the terminal yet. A connection is being studied and appears in government transport plans, so passengers currently need to rely on cars, taxis, ride-hailing services or private transfers.
