Techo International Airport (KTI) replaced the old Phnom Penh International Airport (PNH) in September 2025 as Cambodia’s primary capital gateway. Here is everything you need to know about clearing immigration, eVisa lanes, the e-Arrival Card, and transfers into central Phnom Penh.

All commercial flights to Phnom Penh now land at Techo International Airport (IATA: KTI), located 30 km south of the city in Kandal Province after replacing the old PNH airport in September 2025. To clear KTI immigration, you need a passport valid for 6+ months, a Cambodia eVisa (or Visa on Arrival), and your Cambodia e-Arrival Card QR code.
If you are booking flights to Cambodia’s capital in 2026 and notice your boarding pass lists IATA code KTI instead of PNH, that is completely normal. In September 2025, Cambodia permanently transferred all scheduled commercial passenger flights from the legacy Pochentong site — formerly Phnom Penh International Airport (PNH) — to the brand-new Techo International Airport (KTI), located in Kandal Stueng District across the Kandal–Takeo border south of the capital.
Designed by Foster + Partners as a 4F-class international hub capable of handling long-haul widebody aircraft, Techo International Airport (KTI) was built from the ground up around Cambodia’s paperless border control workflow. If you are deciding whether to fly into Phnom Penh first or land directly near the temples of Angkor, read our Techo Airport (KTI) vs Siem Reap Airport (SAI) comparison.
Airlines flying into KTI — including Singapore Airlines, Qatar Airways, Emirates, Cathay Pacific, Thai Airways, Bangkok Airways, Malaysia Airlines, and Cambodia Airways — verify your entry eligibility at your departure gate before allowing you to board. Arriving at check-in without the right paperwork can delay your boarding or force you into long queues upon landing.
First, every foreign national arriving at KTI by air must complete the Cambodia e-Arrival Card within the seven calendar days leading up to arrival. This digital declaration replaces the old paper immigration, health, and customs slips that cabin crew used to hand out mid-flight.
Second, unless you hold one of the visa-exempt ASEAN passports, you need a valid Cambodian visa. Most travellers apply online in advance for a Cambodia Tourist eVisa ({{USD:79}} all-inclusive) or an Ordinary / Business Class E eVisa ({{USD:89}} all-inclusive) so they can walk straight past the cash-only Visa on Arrival hall at KTI. See our Cambodia eVisa vs Visa on Arrival comparison for a full breakdown of airport queue times and cash rules.
Because Techo International Airport features long, high-ceilinged concourses with clear bilingual English and Khmer signage, navigating from your aircraft gate to the arrivals curb is straightforward once you know which lane to join.
What If Your Old Booking or eVisa Notes Mention PNH?
Cambodia eVisas are valid at all designated international air ports of entry. When selecting your arrival port on a 2026 application for Phnom Penh, always select Techo International Airport (KTI).
The biggest practical difference between the retired PNH terminal and Techo International Airport (KTI) is distance. Whereas the old airport sat 10 kilometres west of the riverside, KTI sits roughly 30 to 35 kilometres south of central Phnom Penh (BKK1, Daun Penh, and the Sisowath Quay riverside), connected via the wide six-lane Hun Sen Boulevard corridor.
Before you step onto your flight to Phnom Penh, make sure both your visa and arrival declaration are locked in. If your flight departs within the next seven days, you can file your e-Arrival Card now and receive your verified QR code by email before heading to the airport.
And if you are still more than a week away from departure and need your Tourist or Ordinary visa first, you can apply for your Cambodia eVisa online and have our team verify your passport scan and details prior to submission.
