Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

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.

They are great with every aspect of customer service. Helped my elderly father and aided him with using the restroom.

Due to the delay of my first flight, my connecting flight with JetBlue was canceled by Singapore Airlines, but the JetBlue crew was very accommodating and rebooked a seat for me. The crew was very nice and had good attitude.

The overall operation needs to be improved. The in-flight services took forever and sometimes ran out of options.

Check in was snails pace, only 1 of the luggage screen was working so long lines, an hour to check in Nobody seemed to want to fix the issue Flight was 45 minutes late Scoot is a mini sized plane ( sardine class plane), literally felt slammed between people

We started with a 2 hour delay due to some airplane technical issues, and while we got a little snack pack, it was a pretty long delay for SQ. The flight itself was short, there's no entertainment on the B737-800 and there's a small snack. Functional.

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.

The meals were ok,but we weren't given any beverages with the food, only after everyone was served food, maybe short staffed but that's not proper

The transfer from Domestic and International was a bit confusing but I am easily confused. I did not eat any food, but the food on the other leg was decent. It was nice they turned the lights off on the night flight. The plane was in good shape, but was a little cramped in economy and I am small. They gave me a customs form to fill out and nobody looked at it as I went through customs. Not a bad flight.

My case was missing a wheel on arrival Heathrow and the staff were unhelpful when i tried to get some compensation stating it was not sufficient damage, i only wish that they at some point have to deal with the same situation it put me in, maybe they would change their attitude but overall it was a good flight

Increase the number of available films, including variety. All other aspects were great.

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 :(

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

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

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!

Pros: "The snacks were nice and the crew was nice"
Cons: "Boarding was TERRIBLE!! Everyone was rushing the podium and overwhelming the employees!! Basically the employees could not control the crowd. Having lanes, or signs in multiple languages for boarding zones would be helpful"
Cons: "Everything was excellent - your system did not register when I clicked excellent for each category"

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 .

During flight, some passengers perform stomping leg exercises which disturb the comfort (I.e. sleep) of other passengers.

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.

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."
Pros: "see SH to GZ prior flight. The same."
Cons: "Same problems. Get KFC or McDonalds to cater. No one enjoys the airline's food which I suspect is prepared on a very small budget. Even a sandwich with a pre-packaged drink would elevate the foodservice."
Pros: "Seat was great. Bedding good."
Cons: "Meal service was rushed with all courses being delivered literally one after the other."
Cons: "food, though i liked breakfast (dim sum and fruits including guava)"

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

Orange juice change to mineral water . Should keep the orange juice.

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

Legs space in the business class cabin is too small and pillow is dirty!

Elderly individual shud be given priority to board the plane together with passengers with children and disabled. Otherwise things are OK.

I enjoy traveling with Malaysia Airlines. The Asian food they serve is pretty good and the red wine was also good. They did run out of beer and only did a couple of water rounds during the flight but the staff were very friendly.

Prompt and efficient boarding. New MH-awards streaming worked first time on my personal device.

On-time & very well priced. All you need on a short 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!"
Pros: "The food was good. It was nice that they supply wet hot towels before each meal. The seat was comfortable with the price I paid for. The rest room is nice and clean and quite spacious. The L’occitane toiletery bag was nice."
Cons: "It would be nice to supply mouthwash in the rest room. It would be nice to have a foot step at the bottom to open the trash container. The comforter is not washed and smells."
Cons: "Even for business class there is no TV screen on each seat. Just one small TV screen on the ceiling for a few rows to share. It would be much better with TV screen on each seat. I was sitting in the first row business class and the air hostess skipped me and didn’t give me a slipper. She gave me a used slipper at the end only without a packet. This is unprofessional to treat a business class passenger"
Cons: "Seats are narrow, leg room poor, and food service is minimal."
Pros: "Beautiful new plane, professional crew, totally decent food."
Cons: "Economy for 13 hours is always a bit rough, but no more so on Air China than any other airline. And the price was so much lower."
Pros: "Boarding was a breeze, flight attendant onboard we attentive, choice of food orders at least two (in business class, can’t speak to first or main cabin passengers.) Flew from LA to Tokyo. Coming back from Hong Kong to LA. Fantastic flights, will use them again."
Pros: "Very frustrated experience. Air China, air Canada, budget air, all push responsibilities away. Budget air got my name wrong, too, which would have caused me to not be able to get on the original flight from China anyways."
Cons: "Still I have not been able to get someone to fix my problem for me although I was promised that I could postpone my return flight by one day because of the delay at Victoria airport. Ended up having to buy a return ticket by myself."
Cons: "kayak charge me for seat assiment and kosher food and millage number Nom of those was in and i had to travel with out food and fight to get seats and make sure the millage number is in"
Pros: "Boarding process may have been the best thing possible."
Cons: "Customer service could be a whole lot better. Seats very uncomfortable for extended flights."
