Limited food options. I dont like chicken or even fish but that’s the only option. Sad to say not impress

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

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.

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

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.

A little more room from the reclining seat in the front of me.

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.

Overall were very good and I was satisfied w/ all the food and services.

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