FAQs - booking Cambodia flights

  • Which airport should I depart from in London if I’m travelling to Cambodia?

    Passengers should select their departure airport depending on where you’re staying in London and if you have a preference for a particular airline. Flights departing from London Heathrow Airport may only have one stopover and therefore have a shorter travel time. You can also travel to Cambodia from London City Airport, London Gatwick and London Stansted.

  • Where can I stop over on the way from London to Cambodia?

    If you’re travelling from London to Cambodia, you can enjoy a stopover at one of the cities along the way to break up the long flight. Singapore Airlines offers flights with a stopover at Changi Airport in Singapore. British Airways flights stop over in Bangkok, while passengers travelling on Etihad Airways may need to change planes in Abu Dhabi, Phuket City and Bangkok.

  • Do British nationals need a visa to travel to Cambodia?

    British passport holders are required to obtain a visa before entering Cambodia. If you are travelling as a tourist for less than 30 days, you can apply for a tourist visa online or in person at the Royal Embassy of Cambodia in London. You may need to provide a valid passport, a recent passport photo, visa fee and proof of travel insurance.

  • Are there any Meet & Greet services on arrival in Cambodia?

    If you’re travelling to Cambodia on business or with a group, Meet & Greet services can be organised in advance so you can enjoy a seamless experience once you arrive at Phnom Penh International Airport.

Limited food options. I dont like chicken or even fish but that’s the only option. Sad to say not impress

Subject: Complaint Regarding Cabin Temperature on Flight SQ447 (DAC–SIN)** Dear Singapore Airlines Customer Service, I am writing to express my disappointment regarding my recent experience on flight SQ447 from Dhaka (DAC) to Singapore (SIN). After boarding, it became apparent that the cabin air conditioning was not functioning adequately. When we initially raised the concern, a flight attendant informed us that it would take approximately 10 minutes for the temperature to cool down once the aircraft began operating. We trusted this explanation; however, the cabin remained uncomfortably warm, and many passengers—including my family—were sweating for an extended period. After approximately 45 minutes, I raised the issue again. While the attendant mentioned that adjustments had been made, the response did not reflect the seriousness of the ongoing discomfort. It was only after about an hour into the flight that the temperature finally improved and the cabin became more comfortable. I also spoke with several other passengers seated nearby, and they confirmed they were experiencing the same issue. As a frequent traveler who has always associated Singapore Airlines with high standards of service, this experience was very disappointing. It has made me reconsider choosing this route with your airline in the future. I hope you will review this incident and take the necessary steps to ensure that such situations are handled more promptly and professionally going forward. Thank you for your attention to this matter. Sincerely, Mohammed Shahriar

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

Really great service throughout and the food was really nice. I can highly recommend thank you very much.

Service excellent would chose Singapore airlines as my first choice

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

plus: service and personal assistance minus: online check-in did not work

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

The male traveller seated in the row in front diagonally opposite my husbands seat across the aisle as soon as the seatbelt sign went off moved across the aisle into the seat in front of my husband for the entire journey from London to Singapore he had his seat reclined and pushed back and the seat touching my husbands knees for the entire journey from London to Singapore. very uncomfortable for my husband.

More Baggage limit Alternative of virtual check in at airport , prefer personal touch with “real person”check in counter for baggage drop

We still get drinks and a snack. Love the gift bags too.

Excellent airline. The plane was clean and the staff were very attentive

The flight was mostly fine, but I really wished that seats had an outlet to charge devices considering the length of the flight (15 hours there and 14 hours back).

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

The setting configuration of the aircraft stinks. Nobody should pay business class fares and be so uncomfortable. The design of facing fellow passengers is a brilliant nincompoop.

USB charging port was not working at my seat 48K.

The flight attendants ignored us several times which was annoying. The sandwich thing wasn't very good but it's only an hour flight, it would have been better to have entertainment over bad food.

Check in was a disaster. 90 minutes and only 2 economy check in desks open. Had to rush to catch the flight.

I couldnt go on this flight and lost all my money over 1,000 UK Pounds as my visa to Myanmar was not accepted :(

No working jet bridge to deplane, with priority customers deplaning last. Followed by bus to terminal.

We were taking the flight MU 8649 from Shanghai to Osaka and the original boarding gate was 20 and we didn’t receive any notification or broadcast about gate changes, and by the time we missed the original boarding time we check thr electric board and realized the gate was changed to 208 Also the flight was delayed by almost an hour and the crew member didn’t provide any explanation, after we finally boarded the aircraft was very hot, the crew member told me the air conditioning was not working and tried to calm passages down by offering iced water, all of us sat in the aircraft for another 40 mins before it finally took off

Seats not comfortable. We had requested vegan meal and it wasn’t given.

did not get a notification about seat selection ahead of time. We didn't end up sitting together.

China Southern was not the problem. I booked my flight through Kayak and also received a booking reference and alert details regarding departure time and gate numbers… however Kayak NEVER actually booked my flight! We were stranded at the airport without a flight for a long awaited holiday!

We were diverted to Chengdu, because of bad weather and finally made it to Chong King about 7 hours later

We bought an upgrade to Business Class at the airport but did not realise that it was not the regular Business Class. The 787 Dreamliner was very dated with the seats not as comfortable as other airlines and some things were almost coming off. We were then told that because it was an upgrade at the airport, we get to sit in the BC cabin but will be served economy class food. So when everyone else got served in china ware, we were given the tray you got in economy class. The wifi does not work. It only connects to watch movies (which is the same as what you find in the ICE) but the internet does not work. The cabin crew while were friendly, were not responsive. Overall, I will never fly China Southern again.

Wuhan - Dubai. Old plane: 1. Only USB charger. No power outlet to plug in.. 2. Super narrow seat layout 3. Toilet cover consistently fell down and hit my back when sitting on it.. :( 4. Entertainment system touch screen not sensitive, and need to press hard or use finger tips to hit. Crew were very nice and accommodating though.

No good but was short flight. Both of our China Southern flights were on time. No surprises.

The flight was okay it was the kayak customer service that was poor, I have been trying to change my name on my flight ticket 3 days before my flight and nothing got done about it even tho I messaged so many times and phoned, all I got in return was that is was being processed and still to this day nothing has been done about it, I think it’s disgusting and un needed stress to the trip.

Quality flight from start to finish. Customer service is evidently very important to this company. The staff really exceeded expectations.

The meals were not the greatest and lacking of appetite but everything else was spot on

cannot get seat information for LAX to IAH when check in in XI,AN

UA is ok. But check in was a very bad experience

I hate that you cannot check in online and when you are at the airport, there aren't any aisle seats left. Also, they could work a little on subtitles for their movies (not everyone is a native English speaker).

It's terrible that we can't do online check in because we didn't buy the tickets directly from Air china. It was not explained until I contacted Chatdeal and we could not sit together.

Communication between the captain/crew and the passengers needs to be improved.

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !

I booked tickets for a family of five and specifically paid extra to select our seats together. We spent nearly $1,000 extra (around $100 per seat) for extra legroom so we could sit near each other. However, despite paying for this, we ended up being separated on the flight. This caused a major issue for our family because my parents do not speak English and rely on me to translate and assist them during the journey. I do not understand why Etihad changed our reserved seats without explanation. I am extremely dissatisfied with this experience. I expect the airline to do better, and I am requesting a full refund for the seat selection fees we paid.

1 hour delay meant missed my connecting flight and 1st day of holiday

We have paid premium price for a business class Cabinet and we have received the old 777 with the following apart business class that is not to standard. It was very disappointing and it’s a very bad reputation for a premium airline company. This aeroplane should be the commission from being as a business class. We will pass this knowledge to our colleagues because the quality of business class in Etihad is not consistent and it is a lucky dip that sometimes you’re getting a good aeroplane and sometimes you’re getting their 30 years old aeroplane. The crew of the aeroplane have apologise and said that they hate this aeroplane and they have complained about it multiple times as well. Obviously Etihad is putting the economy in front of the Customer Experience. For the future we will not take this risk anymore and will fly with established company like emirates.

Etihad Check In counter/Station manager in Heathrow was bothering and not helpful at all. They are rude and not customer oriented

I am a larger than average person and in my opinion i don't think it's fair to allocate a window seat to anyone who is my size or larger, i was seated between 2 large passengers on a full aircraft. The guy in the window seat also occupied a portion of the middle seat (my seat) which made my experience of flying with etihad very cramped and uncomfortable, i was flying from Abu Dhabi to Bangkok. Had this been a airbus 380 it would have been better as the seats are larger but unfortunately it wasn't so i had to endure the 6+hrs unable to get any rest

Surprised at the lower quality of seats on the Boeing 777 in Business Class. Seats are tight and the whole Business class section is jam packed with seats. It doesn’t feel like Business Class at all. Also the way the tray tables are placed with a huge bulky solid metal hinge at knee level makes it so uncomfortable and always anxious that one will accidentally bang their knee on it. Quality of amenities has also declined. Over priced tickets with diminished quality of the entire experience.

The business class experience is fantastic. The crew were polite but often unavailable even when I tried to call them! I even found myself bringing my used dishes and cutlery up to the crew because no one had come to collect it after over an hour.

Very very bad service very tight seats never ever flying with Etihad again

The food is good, but i am nit used to those foods so I can’t really be more detailed.

Dear Etihad Airways Customer Service, I hope this message finds you well. I am writing to express my deep disappointment with my recent flight experience on Etihad Airways, which took me from India to NYC via Abu Dhabi. My flight details are as follows: [Flight Number] on [Date]. My overall experience was marred by a series of significant issues that I believe warrant attention and improvement. These issues include: Bad Conditions of Washroom: The state of the washrooms on the flight was far from satisfactory. They were inadequately maintained and lacked the level of cleanliness one would expect during a long-haul journey. Seating Space and Comfort: The seating arrangement left much to be desired. The seats were cramped, uncomfortable, and the legroom was insufficient for such a long flight. The seats did not recline as expected, making the journey quite uncomfortable. Cabin Cleanliness: The cleanliness of the cabin, including seats and tray tables, was not up to par. The lack of cleanliness impacted the overall comfort and satisfaction of passengers. Excessive Noise: The flight was notably noisy, with disturbances and loud noises making it difficult to rest or concentrate. The noise levels were considerably disruptive. Food and Catering: The quality and variety of meals served on the flight left much to be desired. Furthermore, there were issues with accommodating dietary restrictions, which is crucial for passenger satisfaction. Hygiene and Sanitary Facilities: The condition of the restrooms was subpar, and essential hygiene supplies were not adequately provided. This falls short of expectations for a long-haul journey. Overall Experience: Regrettably, the combination of these issues significantly affected my overall experience during this long flight, making it far from the comfortable and enjoyable journey I had anticipated. I understand that maintaining high standards on long-haul flights can be challenging, but I believe it's vital to bring these concerns to your attention in the hope that they can be addressed and improved upon in the future. As a loyal Etihad Airways customer, I had higher expectations for my journey. I kindly request that you take these issues into consideration and work towards enhancing the overall passenger experience on similar routes. Your attention to these matters is greatly appreciated. Thank you for your time and understanding.
