We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

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.

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.

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

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.

The staff on Singapore Airlines was incredible. I would like to commend LS Reuben from my SQ37 flight on November 19th, 2024, from LAX to Singapore, for his outstanding service and care. During the flight, one of my earbuds—brand new and valued at nearly $300—fell out and became lodged in the box controlling the in-flight entertainment system. I was understandably upset, but Reuben went above and beyond to assist me in this tough situation. Reuben demonstrated exceptional determination and empathy. Instead of suggesting we wait for an engineer, he immediately took action, spending almost 30 minutes searching for the earbud. He even got down on the floor to ensure it was recovered. His genuine concern and persistence made all the difference and turned a frustrating situation into one where I felt truly valued as a passenger. Reuben is a shining example of the remarkable service that sets Singapore Airlines apart. His dedication and willingness to go the extra mile left a lasting impression, and I want to sincerely thank him for his kindness and professionalism.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Really enjoyed the flight. Our flight attendant on the way back SIN-LAX was exceptional I didn’t get her name but she was so kind and went above and beyond to make sure I was comfortable. I had a bit of a panic attack and she checked on me a few times to make sure I was ok. Really appreciated her attention and service. Thank u

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

I recently travelled with Qatar Airways from Doha to Dulles in the QSuite, and the experience was nothing short of exceptional. The QSuite truly feels like a First-Class experience, with its luxurious design, privacy, and comfort. The cabin crew, especially the lady in charge of the cabin, was remarkable—professional, attentive, and genuinely kind. The food was excellent, and the comfort of the seat was absolutely first-class, making the journey smooth and enjoyable. While the in-flight experience was outstanding, I have a few points of feedback. Firstly, the content available in the in-flight entertainment system could be expanded and upgraded to include a more diverse and updated collection. This would elevate the entertainment experience to match the premium standards of the QSuite. Secondly, regarding the Wi-Fi service: while QSuite passengers receive one hour of complimentary Wi-Fi, any additional usage requires a fee of USD 10. Considering the premium pricing of QSuite, it would be more fitting to include unlimited Wi-Fi as part of the experience, further enhancing the luxury offered to passengers. Lastly, I must highlight an issue with luggage handling. Unfortunately, my luggage did not make it through the transit, which was disappointing. While the ground crew assured me that it would be delivered to my home on the same day as it was arriving on the next flight, this promise was not fulfilled, and the delay added unnecessary inconvenience to an otherwise excellent experience. Overall, the QSuite experience was exceptional, but addressing these areas would further solidify Qatar Airways’ position as a leader in luxury air travel.

I was denied lounge facility at airport. Explanation was not satisfactory.

Very unimpressed that I was dumped from the seat I had booked and paid for after check in. Apparently a family wanted to sit together, however as they all were adults I think they should have pre booked their seats like I did. I will be approaching Qatar for a refund. That and the dreadful state of the flooding toilets made me wonder how they managed to be voted the best airline. Not worth the money.

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

Being a QR Platinum member traveling in business class, I expected the staff to be more courteous. Unfortunately, the lady staff was rude attending business class 1K side.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

Besides the flight cancellation, everything else was prefect. Kudos to Malaysian Airlines.

It was a long flight but overall a good one. The one thing that I would comment on is that there is a real problem with disposable plastic products when it comes to the meal service. It would be great for Qatar Airways to find ways to make its meal service more circular and reduce the immense amount of waste.

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.

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
