Airports 

Air travellers enter Cambodia through Phnom Penh’s Pochentong Airport or Siem Reap Angkor International Airport. Both airports are quite modern. The two-storey one in Phnom Penh even offers a First/Business Class Lounge on the first floor at the International Terminal, near to the main boarding gates. Inside is an assortment of services and modern conveniences including wireless internet. Economy passengers can use the lounge for a nominal fee.
Pochentong Airport offers plenty of other amenities including lost luggage services in Arrivals at the International Terminal, currency exchange, a post office and a smoking lounge. Restaurants and bars include Caffé Ritazza and Angkor Pub in the International Terminal; Café Select in the Domestic Departure Lounge; and a food court outside the International Terminal. Shopping is light but good, with a bookstore, two duty-free outlets and a Khmer handicrafts shop.
The airport serves well over a million passengers annually with a capacity for two million. There are 22 check-in counters and 6 gates, serving 10 international and 3 domestic destinations with 20 airlines. There are 380 parking spaces with parking available for up to 4 hours.
Siem Reap Airport is equally impressive. It has capacity to serve 1.5 million passengers and nearly meets this capacity annually. Although tiny and with just one floor, the airport is very pleasant and has a bookstore and a charming boutique selling souvenirs and other goods. There are less than 200 parking spaces, most at the International Terminal.

Public Transport 

There are plenty of ways to move around Cambodia and the best choice for long distances is by air. There are good and frequent connections between Phnom Penh and Siem Reap on President Air and Siem Reap Airways.
Local buses can also provide an exciting means of travel and are good for those on a budget. The popular Mekong Express provides a luxury bus ride for just US$6 between Phnom Penh and Siem Reap every day. There are other companies offering the same route as well. You can also get between the capital and Siem Reap via boat in just 5 hours for about $US25.
The best way to see the country at your leisure is to hire a car and driver. You could drive yourself but it probably wouldn’t be as pleasant as having someone else drive you, especially through heavy traffic. Hiring a motorbike is great for short distances and to see rural areas, but be sure you know what you’re doing!
Getting around in cities is best done by motorbike or by hiring a cyclo or a taxi. Walking can be fun if it’s not too hot and you know the distances and where you are going. However, many of the sights and attractions in Siem Reap are too far apart for walking
