Formerly known as Kampong Som Airport or Kang Keng Airport.
2 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)
2 Airlines have flights from Siem Reap (Angkor Wat) to SihanoukVille, every day, at the moment, with one of them departing 2:55pm arriving at 3:55pm. These flights are with Cambodia Angkor Air.
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+...
A new airline has started service between SihanoukVille and Siem Reap, Sky Angkor Airlines. The 55 minute flight leaves Angkor Wat at 9:50 am for SihanoukVille, and departs SihanoukVille at 11:05am for Siem Reap. For the moment, this is everyday and flight cost $90 one way for foreigners.
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.
SilkAir launches June and December charter flights from Singapore direct to Sihanoukville with effect from 1 June 2015. The charter flight dates are 1, 2, 6 June, 1, 6, 8, 13, 15 and 20 December 2015. At least that's what we read.
Lucky Air has flights from Kunming China twice a week and back.
All these above flights can be cancelled at any time, without notice. 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+. 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.
Skywings Asia Airlines is testing out non-stop flights from SihanoukVille to Seoul, South Korea, but no scheduled flights yet.
Once or twice a week is a charter flight from China to SihanoukVille for a casino run. But we can't find any info about it on the internet.
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... $6 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.
