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.

Overall I was quite pleased with the experience; the cleanliness; the polite and attentiveness of the cabin crew; and the delicious food options.

Ove the A380 planes. Comfortable seats. Served great Indian food and Masala Chai!

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

Overall was a good experience and this particular flight the crew were great too at least in business class. It’s not always the case with flydubai. Few things would make me think twice in the future on this route. 1. The arrival into T3 might sound good but it is a real pain as it takes almost 30 mins to get to terminal on the bus as the aircraft still park at T2. The bag takes even longer . If they just let us off at T2, I’d be home within 30 mins of walking off the plane. Instead it takes 1.5 hours. 2. Due to the timing, the very tiny lounge in Penang is so crowded because half the lounge is closed for Qatar crew. Hardly anywhere to sit. 3. Flydubai app and site has a long way to go and using it is very unpleasant.

Excellent comfort and entertainment. Service poor..Food average with little choice.

Thay crew was so nice.Air hostess il ham was so nice.my mom was little scray with airplan turbulence she help us alot.

Comfort and customer service from most if the crew was great. The crew reassigning passengers should consider the presence of infants when reassigning seats. Unfortunately a couple of oversized passengers were relocated next to us, making this segment a bit uncomfortable, as there was not only extra leg space required. I ended up swapping seats with my husband so our baby wouldn't be impacted. My husband travelled quite uncomfortable as the reassigned neighbour shoulder and arm ended up on my husband's seat

Emeritus is ***** Fly dubai is 0 we need better service for Fly Dubai

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!

Delayed, Bad American style food (not tasty, horrible cheese for a flight to France). Incompetent cabin crew (I asked how to connect by cable my headphones and the flight attendant suggested me Bluetooth which is not available). Good space

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.
