The airline staff was very friendly, helpful and was able to serve us lunch efficiently enough to have plenty of time to eat it. The modest lunch was very tasty. The airline lounge in Siem Reap was very nice with little snacks and drinks. The chair and table arrangement was much better than waiting near the gate.

Although the airline cannot control this, the immigration lines were long and tiresome. The inside of the airplane was clean and nothing torn, but looked dated. The seats were not very soft. The window was not clean enough to take good pictures.

I was so surprised that food was provided for a 45 min flight. The crew was quick. The flight from BKK to Siem was on time, even although there was a last minute gate change. I couldn't comment on entertainment was the flight was so short. The crew was very polite, friendly and efficient. They were as good as any business class service crew.

Another surprise was the excess weight of my luggage. I did get the warning about 20kg limit on this flight on the itinerary, but I hadn't paid much attention to it. I travel internationally quite often and know that 40 or 50kg is the norm. I was charged $8 /kg for 24kg overweight. This end up costing twice as much as the round trip flight. Now, I have to pay similar amount on the return flight. I take photographs from the airplane and found the window to be scratched.

My flight was delayed by 2 hours so I missed my connecting flight in Singapore. There was a huge queue of people who missed their connecting flight cos of an accident in the runway. The airline did nothing to prepare for this situation. It took hours to get another flight organised, communication was non existent and refreshments took ages to come. Airline didn't help with finding a hotel for stranded passengers.

The service from the Singapore Airlines is always impeccable. The food is delicious. The business class seat is spacious and wider than all the US airlines. There are plenty storage space in your seat space. The entertainment system has many choices and has a lot new release movies and shows.

Unfortunately, the ride on Boeing 777 is not as smooth as the Airbus'. The noise in the cabin is louder. The seat is comfortable but the bed is not. First, the flat bed is not transformed by a button and it needs a physical person to flip it over. The mat is thin and I can feel some hard edges while lying down. The noise from the engine transmits to the bed and it is hard to sleep even with the noise cancellation headphone.

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller
At KAYAK we don’t set prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find on occasion that certain prices are no longer available.
