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.

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 👍 👍

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.

Boarding was too soon because we arrived 10’ after boarding began and they were already giving ‘final call’. We just made it. We were at gate 35 minutes before the flight. Also, the departure communication board did not list the flight at all so we didn’t know boarding had already started.

Food and welcome services were good , however we experienced issues with the entertainment system and poor headsets

Lovely staff, comfortable seats. Transit time was short but they had great processes in place to get us on the plane.

2 hours delay, time changes started already 2 days before the flight

Was on holiday with my partner and we booked with Vietnam airlines as it not meant to be a budget airline. They separated us and made us sit at either end of the plane. Not the way I planned to spend my time on my holiday separate from my loved one. How can they separate people on the same booking. They know we are together and spending quality time together.

Ensure there is a choice of food for all customers and also enough food

There was no entertainment and food option limited But the service was first class on an economy flight

Technical problems checking in. Had to wait a long time while they got things ready.

Jetstar was terrible. They left us without boarding passes for the connecting flight for several hours, for no reason. They should have given us the boarding passes for the connecting flight, but instead we were stuck in a “customs limbo” in Ho Chi Minh airport until very shortly before we were to board. No reason for them not to give us the connecting boarding passes.

VN661 flight, the A321 seats are starting to show heavy sign of wear and tear
