Hwinpp knows this, but a lot of the others might not -- Phnom Penh is not really hooked up by air to the rest of the world outside Southeast Asia. And that is of course since, well, you know -- all of those things happened in the 60's and 70's.
Well, things are finally going to change:
Starting 27 March 2011, Air France will begin operating a new service between Paris-Charles de Gaulle and Phnom Penh, the Cambodian capital. Flight bookings and ticket sales are now open.
The three weekly flights between Paris and Phnom Penh, with a stopover in Bangkok, will be operated by Airbus A340-300 equipped with 275 seats (30 in Business, 21 in Premium Voyageur and 224 in Voyageur-Economy), and subsequently during summer 2011 by Boeing 777-200 equipped with 309 seats (35 in Business, 24 in Premium Voyageur and 250 in Voyageur-Economy).
Of course, the reason for the Air France flight to Cambodia is the growth of the Vietnamese travel market. The Air France flights to Bangkok used to continue to Hanoi or Saigon. They are now going to be nonstop to Vietnam, which left the Bangkok flight the possibility of continuing elsewhere.
The Vietnam Airlines flights from Paris were already nonstop, so Air France is just catching up. Now that they are in the same Skyteam alliance, I suppose they will be code-sharing all of those flights.
