The food wasn’t good at all. I skipped meals .

The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

Both the staff at check-in counter and on board were pleasant and helpful. My chicken and mashed potato was good, sauce was tasty, but the zucchini, carrot n other accompanying vegetables were over-cooked a little. (I understand the meal has to be prepared earlier). Yet I would fly on Singapore Airlines again and recommend it to family and friends.

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

The seat in economy class and legroom in Singapore airline are narrower than Korean airlines! I don’t have that comforting feeling flying with Singapore air as in the past!

So happy I flew with Singapore Airlines. The customer service is top notch. I am terrified of flying and the staff made me feel so at ease. Will only fly Singapore internationally moving forward.

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

It was very good experience on board to Sydney with SQ.

OK seats comfortable, easy boarding/embarking, excellent connection to domestic Malaysia flight with baggage checked through without customs. Catering especially drinks borderline ok luckily less important aspect

Comfortable seats in economy, managed a few hours sleep in an o night flight but the food was terrible. Surprising as Malaysia airlines has been good in the past. Service was mediocre this time too.

Vast improvement needed in customer service. I couldn’t get the drink of my choice during both meals (i.e. sparking water and Diet Coke). I had used plastic cups falling onto me from the tray. No eye contact when they thank you on the way out signalling an insincere thank you.

Jia yung was the flight attendant that made this a miserable flight.

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.

It was better than I expected. Thought $5 for a small cup of tea was a bit much!

Overall good trip I find seats a bit hard. We were waiting on board for about an hour for 2 passengers with some document issue. This main our arrival late for our pickup person.

15kg allowance is outrageous. Change of time a few days before departure and more than 2 hours of delay in the end. The worse we’ve taken so far in Oceania.

stuck in the aircraft for over three hours due to engineering work, significantly delayed and made a lot of passengers missed the connecting transport, no mention any compensation

Very quiet plane!! One of the quietest planes we have been on.

Jetsatar refused to take my foldable stroller in the plane, despite following all the rules on dimensions and packaging. Similar thing happened on our previous fight. However, at that instance, they offered to check in the stroller. At this fight, the staff was rude, trying to rush us to board the flight. They made excuses that the stroller was not allowed and even offer to leave it behind and ship it back at our own cost. Fortunately, we had someone else attending. Since the flight was about to take off, they left it behind and send it back to us on the next available flight.

Overall, it was good. The only concern was that I couldn't charge my phone because the USB port didn't work after we took off. One of the crew members tried to restart it but never came back to me with an update.

Comfortable seats, boarding was easy and staff were very nice.

Flight was fine but a domestic flight was called by Jetstar international. This meant going through immigration and custom scanning twice. Long queues were experienced which were frustrating. We were using a wheelchair and exit at Perth needed a scissor lift as no air bridge provided. No fast lane at Perth for wheelchair. The staff were helpful but this system is poor.

The crew were great. The seat was older than an old Holden with a big metal bar sticking right into my back. The passenger next to me complained that hers was the same. The pre purchase system for food was disappointing as the pie/quiche took 20 mins to warm up, arrived too hot and with no utensils. It was one of the most uncomfortable flights I've ever been on.
