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. A customer service officer will meet you at the arrivals gate and accompany you through immigration clearance and customs and can take care of luggage collection, lounge stays and private transfers to your hotel.

My experience with Scoot is very good. Will have no issue flying with Scoot again.

My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

Good flight. Fiod was ready a bit late hence a hurry to finish before landing. Excellent crew and service

Great to have actual hot tastey meal on a flight. Well done

I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed

Cabin Crew always friendly and helpful. Seating cramped - foul smelling from toilets, high risk of disease. Guard personal property such as expensive sunglasses Coffee always awful and cold Meal trays toddler sized Not worth the extra cost to fly SQ - use a budget airline, same if not better experience

Every thing was fine. Some ild classical Hindi movies should be add

People were so nice! Economy seats were small and cramped feeling for me. I’m slender and 6 feet tall

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

They were able to assist my elderly father and myself after not being able to check in to scoot. The counter service was phenomenal. They did what they could to get us on the next plane so we could catch our Connecting flight. Scoot closed early on us so we ended up missing our flight.

We are satisfied with the cabin crew serviceand the quality of meals served.

Lunch Food was tasteful and had variety. Seat was comfortable. However, when I was reserving my seats during booking, the seat configuration showed was 3-3-3, but when I boarded it was a 2-4-2 configuration? Also during booking, I had also bought travel insurance together with my TG booking. However there was no confirmation of my purchase from Allianz and TG. After several emails with TG contact, sales, reservation and Allianz was i able to confirm my insurance purchase. When the policy was issued, the birth dates of me and my wife were wrongly stated and I had to go through another round of emails with Allianz to get it corrected. Otherwise any claims would be void! It was indeed not a very good booking experience!

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 :(

Thai Airways is one of the best airlines in the business. Looking forward to fly again with them.

food poor i said chiken i got pack a pow breakfast lousey .job to explain wot it was ...

After going back and forth with the airline, they never reimbursed the airline tickets. Went around asking multiple people how to get reimbursed and kept getting put back, not satisfied with their customer service.

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

Efficient like all the other flights with them. An outstanding budget airline!

Excellent service. departed on time, and arrived ahead of schedule. The whole restrictions around no food/drink is a bit weird even with Covid. Also, no mobiles and iPad use during takeoff and landing is very 2006!

We bought the business class tickets. The check-in staff and onboard crew were excellent, providing commendable service throughout. However, it was disappointing to find that China Southern Airlines does not have a lounge at SFO. Instead, passengers were provided with a $35 per person food voucher, which fell short of expectations. Furthermore, the quality of the onboard food left much to be desired, marking a significant decline compared to our previous flight experience in 2019, prior to the pandemic.

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.

1. I got very poor check in experience with the counter lady . This is the first airline I ever experienced that no combine check in weight allow . Even we have 4 of us but weight counter by piece . So we wasted lot of time argue and repack . This is super crazy 2. Next I left my Samsung tablet on the plane . And I started to escalate and finally spoke to southern airline lost and found in Malaysia and the amazing answer she give is : system nothing found and please try to call southern airline in china 🧐 . I have been flying many other airlines but this is my first encounterment with such irresponsible airline response and no empathy given to customer . My feeling is nobody bother whether how customer like me feel and I’m just too small for the management to take note .

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

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.

The food was perfect. The boarding process is a bit long. Given the late boarding time, I felt very tired by the time I was seated.

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

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Pros: "Yes, seats were very comfortable and crew members were extremely helpful"
Cons: "Everything was excellent."

An overnight Doha to KL. Great sleep, good service and tasty food in business class

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

The cabin was quite noisy as there were lots of children travelling for the school holidays. Found the selection of movies limited.

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

The best so far coz this time it was all male steward on the economy cluster. They were polite, efficient & genuinely courteous. They do not judge you when you ask for more food & peanuts.

Delayed for 45 minutes. Don't know what's the issue. Other than that, food was not to my satisfaction. However it's okay.

My first course flight (Aor-Kul) was cancelled in the morning, and they asked me to board the night flight hence I need to transit overnight for the 2nd flight (Kul-Myy) that supposed to be on the same day. The overnight stay was not provided, (I'm traveling with my spouse, a daughter (5 y.o.) and an infant (2 months old). Hence I booked Sama Sama Hotel at my own expense (fortunately using my enrich miles points). Other than this issue, all services is good.

Entertainment system was too old, crew were unorganised during boarding

No recognition for one World Emerald member. Business class seat has flat bed

No recognition for one World Emerald member. I got row 1 in business class and it was pathetic. No leg space, cramped space, less recline

Flight was delayed for 2 hours for no reason, then we spent almost an hour after boarding because of the weather conditions. If we left on time we could avoid that 😾

Cons: "Everything was great. Very nice and friendly crew, clean plane, great food. Excellent overall"
Pros: "Friendly crew and helpful staff"
Cons: "Missed connection from PEK to XIY due to delayed arrival and early departure. From XIY to PEK, booked and confirmed 11 departure, changed to 12:30 without notification or explaination. Rushed connections at PEK, pretty much ran from the minute left plan to another terminal, through custom, through all the health check points, security check. Just keep the fights on time and keep the original schedules, not arbitrarily change them."
Pros: "Because of our delay, we flew with Air Thai instead of Air China....much better airline"
Pros: "The crew was accommodating during the flight but spoke very little English and could not help with information on connecting flight."
Cons: "We missed our connecting flight due to a delay and the airline would not let us through because we could have made our second flight...."
Pros: "The price"
Cons: "Staff was not helpful and kind of rude unless you spoke their language. Food options were terrible and not very comfortable seat for 13+ hr flight."
Cons: "Connecting though Beijing from Taipei to LAX is not recommended if you can avoid it!"
Cons: "Seats are narrow, leg room limited, and food is minimal."
Pros: "The seats on business were comfy, the service excellent, the movie selection was fair to poor, the food was also fair to good largely because they served a heavy lunch rather than a light breakfast."
Cons: "The food and movie selection."
Cons: "More TV show choices and more Hollywood movies although I understand it's a Chinese airline not American."
