Formerly known as Kampong Som Airport or Kang Keng Airport.
3 Airlines at the moment have daily flights from SihanoukVille to Siem Reap. One, we know, departs SihanoukVille at 4:25pm, and arrives direct to Siem Reap at 5:25pm. (best we can figure out).
4 Airlines have flights from Siem Reap (Angkor Wat) to SihanoukVille, every day or a few times a week, at the moment, These flights are with Cambodia Angkor Air, Cambodia Bayon Airlines, Sky Angkor Airlines, and maybe JC International Airlines.
Tickets for the Siem Reap / SihanoukVille flight are about $110 for a one way ticket, but sometimes with all taxes could be $80+... or $35+... or $150.
Cambodia Bayon Airlines lists flights between SihanoukVille and Phnom Penh for $40 to $130, (round trip?) and looks like it stops in Seam Reap on some flights. This make the journey between 35 minutes to 3 hours and 15 minutes. So you might want to check the flight time before booking.
Lucky Air has flights from Kunming China twice a week and back.
Cambodia Angkor Air has five roundtrip flights per week, between Saigon, Vietnam (Ho Chi Minh) and SihanoukVille, every Tuesday, Thursday, Friday, Saturday and Sunday.
Air Asia has flights between SihanoukVille and Kuala Lumpur, Malaysia. 1 hour and 45 minutes. Monday, Wednesday, Friday and Sunday afternoon flight.s
The one-hour flights are scheduled to take off at 12:40 pm from Sihanoukville City and 14:50 pm from Ho Chi Minh City. (Saigon) (they do have 6+ hour and 19+ hours flights listed for this trip on their website for booking, so make sure you get the right one!)
Altogether, there are about 50 regularly scheduled domestic flights and 15 international flights a week per week to or from the SihanoukVille Airport. Charter flight are now common here as well.
All these above flights can be cancelled or schedules rearranged at any time, without notice, and for any reason... And in the past, this has happened several times.
But the good new is that you can get a private taxi for a 3+ hour ride from the Phnom Penh Airport to anywhere in SihanoukVille (or back) for $50+ (single person or group, same price). 24/7. Possibly quicker, much cheaper, and much more convenient than taking the half hour to 3 hours and 15 minute flight. (not including going to and from the airport, and arriving early for your flight, and getting out of the airport, and then maybe your final destination in Cambodia). Especially for groups traveling together. Door to door service.
Flights between Kuala Lumper, Malaysia and SihanoukVille will start in August with Air Asia.
We're hoping for non-stop flights between SihanoukVille and Bangkok (coming soon!?), Europe or America, but we're not holding our breath.
All this is subject to change at any time, and many times does. Sometimes daily but usually weekly. We'll try to keep you updated.

There's an airport bus or group taxi service at the SihanoukVille Airport running before every outgoing flight and after every incoming flight for a 20 minute ride to or from town... $7 for the bus. Check with your travel agent for details.
There's no bus at the Siem Reap Airport (that we can find). You'll have to get a motorcycle taxi, tuk tuk (cart pulled by a motorcycle), van or car between town and the airport. This can cost anywhere from $1 to $12 from the airport to most any hotel in town. The trip is about 7 KM and takes about 20 minutes. No idea why there is no regularly scheduled bus service.
The SihanoukVille Airport has undergone major renovations to turn it into a major airport in Cambodia. New runway extensions, and terminal renovations. The airport is in quite nice condition, but not many services in the airport. It's quite small, but enough for the one or more flights a day going through.
The airport is open to charter flights now.
