ChrisFlew with Malaysia AirlinesKUL-LHRFeb 2024
It's 14hrs and feels like it. Pay the small amount extra for the "premium economy " seats- there are 3 rows in a separate cabin and it just feels more relaxed and comfortable with a bit of extra legroom

Take MAS for its Malaysian Hospitality & you’ll never regret it 😍

Airline reviews

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Everything was great keep up the good work 😁, can't ask for more.

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

I was a member of Krisflyer for ten years, but my last flight to Tokyo was a disaster. I had to stand in line for four hours before check-in because they were late opening the counter, and there were more than 50 people behind me. The plane was extremely small, and the food could have been better. When I dropped off my stroller before boarding the plane, I expected to receive it upon exiting for my transfer. However, they returned the stroller to the checked baggage because they said I was late getting off the plane. Of course, I was late; they assigned me a seat at the back of the aircraft, and I was traveling with a baby! The worst part was when I arrived in Jakarta. They damaged my stroller and refused to approve my claim, so I had to pay for stroller rental because of the damage they caused. I don’t know what happened to Singapore Airlines, but I felt like I was flying with a budget airline.

Everything was good except food , food choices was very less. Washrooms were closed.overall good experience.

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

The seats were more narrow than at other lines. Food was mediocre (economy class)

The crew have great customer service but their economy seating isn’t the most comfortable for a 220lbs+ guy and the food wasn’t bad, but wasn’t exceptional, either.

Food option Hindu veg to Hindu non veg request was unheard

The boarding process was smooth and the stewardesses were nice. Some delays with drinks at the end of the flight, but no issues.

The plane seemed pretty old and the food was not good

Flight left on time. Bags came quickly. Crew was nice. But internet never worked and the food was awful.

Seat 💺 was all the way on last row. Food was okay .

Charged for internet that never really worked. The food selection was just ok.

Ticket price is competitive, flight time is punctual, aircraft cabin is clean, food is average. Can improve on serving system of meals on a A380 airbus. I had only 15 min to eat my meal. There are lots of people to serve & took a while for food to make it down to my row.

Poor flight aircraft very old Crew was friendly 1 person though

The service was excellent. We flew coach on this leg of our trip and it was still very pleasant.

We was missed the flight They doesn’t lest us fly next flight without payment They charge me 606 hundred dollars What is very unacceptable,our first fight ticket was almost 2000 dollars, again paid 700 it’s hurt … airlines need to do something please

The food options for children is limited The business class bed is not fully lie flat, and this is an uncomfortable sleep

They didn't give us Nothing to eat, come on..... 1 package of chips and a glass of soda won't do anything to the company

The staff were nice people, the food was very cheap, one of the meal was a sandwich or nothing, I couldn't buy any food, mind expensive duty free WAS available right away. 🤒

PLEASE DONT TAKE FORCEFULLY(SIZE APPROPRIATE) CARRY ONS FROM PASSENGERS WHO FOR SOME REASON NEED TO KEEP IT

It was great. My seat was comfortable. The bathrooms were clean . The service was superb . I travel a lot and I have been in 64 counties. I wish I could fly first class, even though I could , but I prefer to budget my yearly travelling expense on actual visiting , not on flight. Anyway, my point is that your economy was far much better than other airlines as good as Air France. The flight attendants and all crew were polite and very helpful and respectful. Thank you for making my long trip tolerable.

I slept the whole flight so I can't tell you about the food and there was no entertainment offered. Crew was very nice, seats were comfortable in business, and boarding was easy.

I took this flight to be able to fly with Swiss instead of Air Canada from Geneva.. The AC planes have a better outfit in Business class than Swiss, but the service aboard Swiss is really best, first-class, as is the food and beverages. Though using the same plane model (A330-300), the interior setup of the cabin starts to show its age, but IMO the planes are better serviced by Swiss than AC. I had in my recent trips with AC way too many technical problems that led to delays or even complete cancellation of my flight.. Their fleet is aging (average 20+ years) and the maintenance has taken a toll compared to years ago. Cutting costs in every corner has to be paid sometime by someone, and it's the travelers at the end that pays for it. Unfortunately for me, flying directly to Zurich puts a much longer after-fly trip on me than Geneva.. so I might go back to direct flight YUL-GVA, even if I don't like flying with AC.

We are flying with Swiss for a long time but this time was terrible do to are flight cancellations we are in some bad hotel with out normal food

It is a good airlines, very professional very good food. I wish they offered free luggage is the only thing.

Nothing special.. they could have provided something to eat without a charge

For the price of the ticket it's probably the best service in the world

Excellent once on board. Security staff at Johannesburg rude and aggressive.

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

It was great. The airline staff was very friendly. The FRA security was a bit harsh doing their job but friendly overall.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

This was the best carrier, comfort, service, good food, on time experience on a long haul flight. New, clean, quiet, smooth aircraft!!!

I understand that German food tends to bland & tasteless, but please try to incorporate some flavor in your food. Also, always have chicken as one of the options.

Good staff help. Seats do not have enough legroom. Bus from plane to terminal was annoying.

Seats in the center row have obstructed leg room. Entertainment center did not respond well. Staff was good, but coukd be of limited help

No assistance as requested. Very late take off. Very hard landing And again , no assistance after landing

Staff was helpful. we left on time and arrived early to destination.

I have noticed that the airlines, including this flight, pretend there is going to be turbulence, announce such, and say they can’t do beverage service. There is no turbulence and the seat belt light goes off 10 minutes before they ask for tray tables up and seat belts back on. They are just trying to spend less money and it’s quite transparent

Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.

The food was ok, but not great. They delayed boarding in Portland and did not enforce group boarding. But the crew was excellent, went above and beyond.

The food was pathetic. There wasn't much leg room and recline space for such a long flight. No tea/ coffee for a 2-3 hour connecting flight without purchasing! Really!?

No longer a premium carrier and no better than the low cost .

Service was very good. Because I use a cane, I was allowed to use Priority Boarding. Biggest problem was extremely limited leg room in Economy class seats. For airplane food, it was alright.

Terrible. A 6 hour delay and no one could be bothered to communicate or help change routes to avoid unnecessary delays and frustration

Was late but that airport/storm fault. Flight was full but comfortable. Food quite nice. Unfortunate that I had a rather miserable attendant, others were much friendlier

Changed flight terminals/gates twice. The staff and hospitality was good.

Boarding was efficient. Flight left on time. Wasn’t full so we could spread out a bit. Food was ok.
