Air travel in Southeast Asia is growing at a rate well above the global average. According to SITA’s latest Travelers’ Voice, Passenger IT Insights 2025 report, nearly two in three travelers now expect faster airport processing and more control over their journey.

Cambodia has responded with Techo International Airport (KTI) — a landmark project by Cambodia Airport Investment Co. Ltd. (CAIC), a subsidiary of Overseas Cambodian Investment Corporation, in partnership with the State Secretariat of Civil Aviation (SSCA) — bringing world-class infrastructure and SITA’s next-generation airport systems to the country’s new capital gateway.

Replacing the former Phnom Penh International Airport, Techo International Airport represents the centerpiece of Cambodia’s aviation strategy to attract international visitors and boost trade. The three-runway airport can handle 13 million passengers annually in Phase 1, with capacity expected to increase to 30 million in Phase 2 and 50 million in Phase 3.

For the first time in Cambodia, travelers can enjoy a fully digital airport experience from check-in to boarding. With SITA’s self-service kiosks, automated bag drops, and biometric eGates, passengers can move through the airport with greater speed and ease. SITA Bag Manager tracks every bag in real time, reducing mishandling and giving travelers peace of mind through full baggage visibility.

Behind the scenes, SITA’s Airport Management System and Airport Vision keep operations running smoothly by giving airport teams real-time insights they can act on. These intelligent platforms help streamline workflows, anticipate disruptions, and enable faster, data-driven decisions to keep flights on schedule and passengers informed. Together, these technologies create a smarter, more connected airport ecosystem — one where efficiency, accuracy, and passenger satisfaction come together seamlessly.

“Southeast Asia’s aviation market is growing at record pace, but that growth brings complexity,” said Sumesh Patel, President, Asia Pacific, SITA. “Techo International Airport shows how technology can turn that challenge into opportunity. By adopting scalable, data-driven systems from day one, CAIC has created an airport that can grow sustainably and be resilient in the face of disruption while delivering a world-class experience for every traveler.”

29 airlines are already connected through SITA’s Common Use Terminal Equipment (CUTE) platform, ensuring seamless collaboration between airlines, ground handlers, and airport operations. The integrated setup also includes Local Departure Control System (LDCS), Pax Check, Pax Locate, and SITATEX messaging — all designed to connect airport stakeholders reliably and securely.

As one of the region’s newest greenfield airports, Techo International Airport stands as a model for the next generation of smart, scalable, and sustainable aviation infrastructure in Southeast Asia — ready to meet tomorrow’s travelers today.
