It is not so much I had bad experience with Singapore Airlines, but with Kayak and particularly Underpricer. My wife and my seat arrangements were changed some times after we booked our tickets and reserved our seats I February 14, 2026. However, after our arrival we realized that we were separated and sitting in different isles. Our return tickets indicated the same. Our several calls to your Underpricer customer care were useless as they cared how much they could charge us rather than actually help us. At the end they referred us to Singapore Airlines. If that was the solution, why did I have to call your Underpricer customer care. I will definitely erase your app from my phone and I will never use Kayak for future traveling. After all, there are so many agencies that I can use other than your company.

It was good but n it to the same standard as London to Singapore

Great flight attendants as always, they were super helpful and friendly. Made my kids super comfortable during long flight. The food were fine, some great taste some not so much specially the scramble eggs thats too watery. And maybe since its general food, better to not serve coffee pudding that kids cant really eat or maybe just serve different pudding for kids.

a longer gap btw the supper and breakfast would have been better - felt like the sleep was way too fragmented on this red eye flight

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.

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.
