We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

My groups frequent flyer star allianceUnited airline miles was not accepted. The Singapore premium economy bag had to be requested, it was very lacking- no toothbrush. I paid more than double than economy but could only use the bathrooms sharing with economy which was hardly available and had to wait in line. Is the 2X $ worth it just for a larger seat???? It is questionable. Seats were not that comfortable. My husband’s seat had white stains on it- had to wipe it down. Our headphones did not have covers on it. Food- way too much.

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

It was a middle of the night changeover, so we were all ready for sleep. Staff were helpful and managed a few hours sleep. Food options were good.

Didn't like much at all Nowhere near enough legroom, narrow seats. Aisles not wide enough for safe food trolley access and husband had his knee hit cos not enough leg room. Would take a lot to convince us to fly Singapore Airlines again which is a pity cos it was always our go-to airline

A 16 hour flight from Singapore to Los Angeles had only 2 meals. Please make it 3 meals.

Once again the meal served was delicious - we got chicken rice

Overall good experience, convenient Changi Airport, even the layover was long.

Singapore Airlines from Mumbai was late, we were rerouted to Copenhagen and then to Los Angeles. As senior citizens, we should have been given a hotel voucher for a night and fly out the next day. I hope Singapore Airlines should give us a credit in good faith if they want us to fly with them. I doubt it, but you never know.

I had to change a flight date and it cost me $800.00 dollars. In the past, if there was room on the flight(which there was), Singapore Airlines simply re-booked me. This might have occurred because the office in Bali where I could interface with a human face to face is now closed since COVID. I naively figured the ability to change my flight into my decision to go with Singapore Airlines as it does cost a bit more. I will still fly on them as they are superior to the other carriers by a fairly large margin, especially for my needs.

They charged me $900 to board my flight I already paid for just because I missed my previous flight. I do not recommend this airline by any means.

Not good. Small seats. Not enough food that customers wanted. No special requests were given that i could see. Slow response from flight attendants

For a transpacific flight, flying economy is awful! The seats are cramped and its meant for petite folks! Good luck if you have long legs. BOARDING - AWFUL, we got to Hong Kong - the gate was listed, but upon arrival, there was a MESS of boarding procedures, they basically DIY'ed how to board but making three lines and putting three ground crew to check for passports in the terminal area. THEN to make it worse, after going through that cattle process, all of a sudden you see people standing and looking confused, apparently we were told to get in line to board, but the AV notification wasnt even working. So people started cramming in line - worse than cattle. One saving point, the flight crew forgot to serve me dinner and after waiting for it, I fell asleep since this was a midnight flight. After letting a crew know that I was forgotten, all of my meals were served first !!! Yay for being in the economy seats! Nothing much to write home about once more!

Was a nice experience, crews were nice and accommodating. My only complain is the super tight leg room for the economy class.

The crew is amazing, very attentive. They went above and beyond when we had a small spill. the food on this trip was not nearly as good as other Cathay flights. The economy seats are very comfortable, but when the person in front of yo reclines, you need to recline to see your screen or be comfortable.

Cathay Pacific helps me with the planning due to weather delays. Well planed flights.

Flight crew went above and beyond to make sure the flight was enjoyable for us!

Both my husband and I ordered the fish for dinner and we both got sick and throwing up on the plane. I don’t think the seafood was handled properly and I for sure will not order fish the next time around.

Im now late to my appointment because of delayed flight

Dinner was served at the wrong time as soon as we boarded. Most were sleeping.. there was no food service carts for hours. We had to specifically ask for water, snacks etc. for the 15 hour plus flight, there should have been 3 meals served. Instead we only got the breakfast 1 hour before landing. Will try other airlines like Qatar for future travels.

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

Did not take as cancelled 3 time so took another airline

It was a 2-hour flight so they didn't have much time for serving food. There was some turbulence so they could not serve hot coffee or tea for the safety reason. Good service, good tasting food, nice plane, a little bit of delay.

The IFE is quite unconvenient if using our own device. Not all passenger brought their own earphone/headphone.

Ok, but legspace on MH0127 from Kul to Per was too small. It was not possible to tilt my seat which I don't understand because the seat in front of my could do it. So I didn't rest on the flight. Also, the crew was probably understaffed because it took very long time to take trash after the meal. Everything very different from the flight with Malaysian Airlines from London to KL.

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

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.

Boarding took forever. It's also weird that we paid more (for preferred seats) to get on the plane last. Inflight WiFi never worked the entire trip. I want my money back.

The cosmetic condition was pretty run down. The carpets were badly worn out. Even the paint on the wings was chipped and peeled! Looks like they are running these 787s to the ground..

WiFi didn’t work on both sectors so made killing time harder - planes clean modern and good flight crew - would do again if WiFi works

6hrs fly they dont give you a glass of water from seoul to singapore need to buy drink and food plus they charge for bag on international fly is always Free 1 bag from seoul to singapore is Not a local fly you are traveling true asia same story from singapore to Bali no water drink after payment for bag drink cost more the regular airline Well never use this company again we use regular company like Delta korea japan China and even scoot parent company Singapore Air

We had 2 attempts to land at Singapore Changing during a thunderstorm. Everything was delayed by 1 hour plus.

Boarding was not accordingly after front seat, bmf then back seat. This delayed for at least 40mins or more. The staff at Jakarta can do better. Is chaos at the entry to board the plane. This tarnished Scoot reputation when everyone was talking about it.

The crew was not customer oriented at all, even confrontational . The aircraft needs more attention to detail as far as comfort, and the 1 hour sitting at the gate with no air is inexcusable

We flew on the 787 Dreamliner direct to main gate at KLIA2, quick entry via eGate and on the train 41mins after touchdown. Go well SCOOT

Was on scoot plus. The only good thing about the flight was the spacious seats. Tables and armrests were extremely dirty Food: bad Entertainment: non existent Wifi: unable to connect, then was painfully slow that we couldn’t even send messages Good thing we had a night flight, so we just slept throughout.

Not clear why boarding passes could only be issued at the counter and not through the kiosk. I had already check-in on the web, so waiting to obtain a boarding pass 1.5 hours before the actual flight defeats the purpose of early web check-in.
