Crew and in flight experience were great! I felt safe in the plane. Only downside was sitting in economy and the seat/person in front of me who had their seat reclined most of the flight (9 hrs) which made it difficult to eat or be fully comfortable.

FAQs about flying to Phnom Penh

Getting around Phnom Penh

Walking around the centre of Phnom Penh is an enjoyable way to get a feel for the city, but to get around the suburbs, travelling by tuk-tuk or taxi is advisable. You can rent motorbikes at a very cheap rate as well, if you are confident about dodging traffic (and don’t forget to rent a helmet as well). However, a more sedate form of local transport is the fleet of three-wheeled cycle rickshaws.

Getting from the Airport to the City

There will be taxis gathered directly outside the arrivals terminal once you have landed on your flight to Phnom Penh, and they should charge a flat rate to get you into the city. For an even cheaper ride, leave the airport and catch a tuk-tuk or one of the many motorcycles that will ferry those with less luggage into town. There is also a city bus that will take you straight to the Central Market.

What airport do you fly into for flights to Phnom Penh?
Travelers will need to book flights to Pochentong (PNH) if they wish to fly to Phnom Penh. The Phnom Penh airport is 5.0 mi from the city center.
