Food was terrible , uncomfortable seats, WiFi did not work, will never fly Singapore again.

Really great service throughout and the food was really nice. I can highly recommend thank you very much.

Never book through Kayak. They can offload booking to third parties that are completely horrible.

Kayak really screwed up by offloading the booking to a third party. They were completely inept and caused a bunch of toil. I will never use Kayak again.

They ran out of the second choice of food was stuck with fish

First time flying with Singapore airlines and I’ll give them two thumbs up 👍 👍

No frills airline with minimal leg room and no entertainment

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

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

There were no food or entertainment on this short flight. Friendly staff even before getting on the flight. The seats were snug but it was quick flight

Good flight. On time. No problems. Plane was clean. Service was as you would expect. However nothing special, just a good flight.

Very friendly staff. No food service and no entertainment. Only 1hr 20min flight

High fees for excess checked baggage and somehow ridiculous rules for carry on bags.

Flight was late, food and drink an extra charge, my carry on is five rows behind me, and the seats are too narrow. Don’t ask me to be happy about it

I bought flights in August and there wasn’t a flight in the system

Our 6.30am flight was boarded then cancelled to fly at 10.55am . We were flying to Brisbane to attend a funeral at 12 noon an hour away . This means missing the funeral due to unreliability of Virgin . Unimpressed !!

It was with Link Airways and the Saab 340 jet was noisy and little comfort.

They didn’t sent my luggage I got it 24 hours later

Plane was late and they wouldn’t check our bags through to Tokyo
