The friendliness of the attendants, and the quality of the service.

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

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

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

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

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Everything was great keep up the good work 😁, can't ask for more.

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

The crew and their service was top notch, but the plane itself seemed to be on the older side and worn out. Also, the food could’ve been better. 9 out of 10.

Excellent- a lot of food Disappointed with the premium economy pouch- did not have toothbrush and tooth paste or socks. Other airlines provide them
