The quality and the quantity of food was terrible. I was starving to death at the end of the flight. Used serve 3 meals long time ago, now reduced to 2 meals during the 17 hours flight. Never offered wine or tea to us. We have to ask . Extremely hard to get the attention of the flight attendants. They intentionally ignore us to minimize the service. Bathrooms were dirty

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

Fast and efficient flight. Wifi worked well. Food selection could have been better

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

I loved the full Taylor Swift selection but felt that the other selections were limited, didn’t span the popular music eras nor a wide enough range of music genres. BUT the seat and bed were GREAT (it was wide, long enough, had great storage, firm enough to uphold body postural comfort). Outstanding crew and really great food - gourmet innovative dim sum breakfast so different from the boring standard fare offered by many other business class products.

Crew is excellent Wifi needs to be improved in order to connect to the internet.

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

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

Very nice experience in business class. Flight attendants were attentive. Foods and beverages were very good.

Milan airport was bad experience. They should be more polite.

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

Loved everything! This flight had premium economy and I didn't see an option to upgraded to premium economy OR buy premium economy tickets. How come?

Flight attendants were great. Comfort of seat and lie down bed pretty good. Food was very mediocre. Wine was good (red French wine) although I should have taken advantage of having more! :-) it was too late on the flight From znz—I was tired…then too early from Dubai. Woman sitting behind me dropped a full bag of garbage on my head while I was sleeping…orange peels, wet partially eaten food and very smelly food garbage which I literally had to pick out of my hair, off my face and away from my pillow. Not the airlines fault but still a very unpleasant experience.

The lounge staff at reception were inefficient and robotic. Boarding process was chaotic at the gate with no priority for business and first. At arrival into Dubai, no upper deck door . Food option and quality for this flight was awful . Thankfully the bar is always good.

Not that good The crew in the plane were rim professional & almost lost in their work distribution

Crew was not good and service was bad. Not happy

Over all good service but from Dubai to Delhi horrible service. Not happy

1. Please deploy better trained and courteous staff. 2. Wheel chairs be available at all steps of layover till boarding gate. 3. Food services be also improved . 4. TV and phone charging facility be also provided.
