Airline reviews

I had selected seats together for my family of three when I first booked my tickets in February. However, I realized only when I checked in at the airport that the seats I had selected were no longer assigned to us and we were completely scattered across three different middle seats instead of being seated together! After requesting the Singapore staff to have us seated together on a full flight, they managed to find something but it was right next to the rest rooms and the whole journey of 15+ hours was really unpleasant. They said that the seat selection isn't locked and the airline can reallocate the seats anytime. No one ever told us this and it was a terribly unpleasant surprise. Will avoid Kayak/underpricer and Singapore in future

Very concerned with guest comforts going out of their way to accommodate special dietary needs when the guests hadn’t pre-ordered.

Clean modern comfortable. Food could have been better, I only ate breakfast I wish they wouldn’t wake sleeping passengers who would rather sleep through dinner. No tea or coffee for breakfast

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

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 👍 👍

Food was served to different people at different times and it wasn't clear why. The crew apologized for the wait. But it felt odd and inconsistent. They could use charging ports on each of the seats. Mine didn't have any. Also, they could've offered more snacks. It was a 12+ hour flight and no snacks were ever offered. Everything else was OK.

No frills airline with minimal leg room and no entertainment

The crew was very courteous and professional. the flight is relatively clean and comfortable.

SQ service is great as always. However, the food quality seems to have gotten a lot worse recently.
