SQ is a market leader for good reason and its 787 this time was actually comfortable and the service top notch as always.

No frills airline with minimal leg room and no entertainment

The crew was very courteous and professional. the flight is relatively clean and comfortable.

The flight was very late, sitting on the plane for over an hour and missed our connecting flight from Singapore to LA. As senior citizens, we were rerouted to Copenhagen and then to LA. They should not do this to senior citizens. They should have given us a hotel voucher for a night, then catch a flight to LA the next day. Singapore Airlines should grant us some kind of credit for the next trip, if they want us to fly with them. I doubt if we will ever hear from them.

I loved the comfort of the flight and the hospitality of the flight attendants!

Awesome as always. I wish though the cabin for premium was upgraded.... Same old sane old :(

Even though it was a very full flight, the service was still excellent, the plane did not feel too cramped and cabin crew made a sincere effort to help passengers find overhead space for stowing luggage.

We started with a 2 hour delay due to some airplane technical issues, and while we got a little snack pack, it was a pretty long delay for SQ. The flight itself was short, there's no entertainment on the B737-800 and there's a small snack. Functional.

Airport lounge for business class is too crowded and not comfortable. Poor foods and facilities. Boarding was delayed. A lot of coughing people in the flight even in the business class, which indicated poor screening and health risks.

I was very impressed with this airline. The flight was comfortable the plane was clean and the attendants were very nice. The zipper on my suitcase broke after I checked it. The airline wrapped it in plastic wrap, so it wouldn’t continue to fall apart. Every item I had in the suitcase was there when I got to Los Angeles. That is above and beyond!

“They carefully called each boarding group in turn, only to herd everyone onto a bus for the drive across the airport apron. By the time we reached the aircraft, all semblance of orderly boarding had disappeared and it became a complete bun fight to get on board. Rather nonsensical really — why bother with boarding groups in the first place?”unless you are at an air bridge!!!

Boarding was not as per sequence Light snacks were not available Window had hair oil stains and water condensation

3 hours delay ,we changed plane after boarding and waiting inside

Forthright communication to the customers regarding services offered and any fees involved.

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..

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.

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.

We were delayed, but there was never any update given. Everyone was standing at the gate as boarding was supposed to commence at 13:10 for a 13:55 flight. We didn't actually start getting on the shuttles to the plane, until after 14:00. No updates, no information given at all.

It was a cheaper flight and it arrived early. I thought the crew were pretty noisy for an overnight flight, and my friend was not able to sleep because of the noise. Also I think it’s absurd they don’t provide complementary water. Why does everything have to be a surcharge? Airplanes are dehydrating and it would be beneficial to help passengers stay healthy.
