Summary

Techo International Airport (IATA: KTI) opened on 9 September 2025**, replacing Phnom Penh’s older city airport as the capital’s main hub. The one-year mark is useful for property readers — if the framing stays tied to published aviation data rather than recovery slogans.

State Secretariat of Civil Aviation (SSCA) figures reported by Construction & Property and Asia News Network / Phnom Penh Post show that in January–April 2026, Cambodia’s three international airports handled 23,204 two-way flights (about +2% year on year) and 2,428,009 two-way air passengers (about −4% year on year), while two-way air cargo reached 30,448 tons (about +36%). In a May 2026 operations snapshot from the same briefings, Techo averaged about 708 two-way flights per week, ahead of Siem Reap Angkor (about 224) and Preah Sihanouk (about 50 per Construction & Property; Asia News Network printed a lower Sihanoukville weekly figure in the same reporting cycle).

Holiday peaks were busy. Angkor Times, citing Immigration figures, reported that Techo handled more than 100,000 international passengers in the 13–19 April 2026 Khmer New Year week, including more than 34,000 foreign travelers. SSCA commentary in that coverage noted nearly 350 departing flights carrying close to 40,000 passengers across 14–16 April.

Airport throughput is not the same as a national tourism rebound, and it is not a reason to invent district price lifts or rental yields.

What this means for Phnom Penh

Airport-corridor housing — southern Phnom Penh, Chbar Ampov, Koh Norea, and Kandal Stueng — is a multi-year access story, not a one-week flip. More scheduled flights improve connectivity; they do not finish unfinished towers or substitute for title and completion checks. Prefer completion status and clear use-case over “near the new airport” marketing.

What to do next

  • On corridor stock, ask for handover and completion evidence; treat peak-week passenger spikes as capacity proof, not a yield model.
  • When citing aviation figures, name SSCA (via Construction & Property / ANN) or Immigration (via Angkor Times) with the period.
