The airport moved, and most advice has not caught up
Phnom Penh switched to Techo International Airport (KTI) on 9 September 2025, and was formally inaugurated the following month. The old Phnom Penh International, close to the city on the north-west side, no longer handles the traffic.
Techo sits roughly 20 to 24 kilometres south of the centre - about 24 km from the Independence Monument. Allow 40 to 50 minutes, and more in the evening peak.
That is roughly double the old airport's run, and it is the single most common out-of-date fact in Phnom Penh travel advice. Hotel listings, guidebooks and blog posts written before September 2025 quote twenty minutes, and a great many of them have not been revised.
Cambodia's other airport moved too. Siem Reap-Angkor International opened on 16 October 2023 about 45 kilometres east of Siem Reap, a 45 to 60 minute drive against the old field's ten minutes - see the Siem Reap airport guide.
Both moves together change the domestic maths. Phnom Penh to Siem Reap is 55 minutes in the air but about four and a half hours door to door, against five and a half to six on a bus that drops you in the middle of town. The transport comparison sets that out.
