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!

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!

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

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.

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

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

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

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.

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.

Food no so good. Extra charge to much for front seats cost me £163 then other people sat near me for nothing 🤬

Except for the uncleaned tray, and the delay in serving food for our section (which may have been due to the location of our row) everything else was good. The crew were very professional and responded to our requests promptly throughout the flight. We as a family were not disappointed by Emirates.

It was great, a little more leg room would have been better particularly since we were in premium economy

Good flight overall. Good options of food on NY-Dubai-Mumbai leg. Not that good reversing back. The flight crew is courteous and professional as always. The seating was much more comfortable going into Mumbai than coming back. Cheers!

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

Boarding, seats, entertainment and service were all great. The food was great except for the fact that there were too many sweet items.

everything was great. I don't use on-board entertainment at all (I just read or sleep), but I appreciate that I couldn't hear anyone else's!

The ground staff on Islamabad is horrible. The on board services are excellent.

The entire crew went above and beyond. This was our first flight with our 3 month old, and they were accommodating and friendly. The crew is attentive and marks a HIGE difference to the regular runs with Avianca and LATAM.

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

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

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

I value punctuality and customer service, which were exactly what I experienced in this flight.

Landing was smooth. Baggage check in was given complimentary B4 boarding was like a surprise gift.

If you are over 170 cm, i would implore you to select an exit row or front row seat. You will not be able to sleep. Extremely uncomfortable.

My second consecutive experience of flight delay between 1.5 and close to 2hr. Resulting upsetting my biz agenda and additional expenses on local transportation to catch up

Expensive Poor check-in process staff only arrived 2h before boarding which is not a par with international standards Cabin was overly warm No seat Pocket No in seat charging No entertainment No WiFi option Slow cabin service Limited purchasing options Boarding was good Staff were presentable Flight was safe and on time

The flight attendants were not passing out soft drinks. They skipped a lot of rows and passengers were complaining.

The boarding a bit late but overall no drama. Will fly with jetstar again someday for sure.

seat legroom was quite narrow, so i could feel the person’s knees behind me.

Honestly, I Wouldn’t fly Jetstar if I had a choice.

Paid top dollar, and outrageous add ons to get squeezed into an uncomfortable seat with the least leg room possible. Probably best to avoid air travel whenever possible, maybe forever.
