Really great service throughout and the food was really nice. I can highly recommend thank you very much.

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.

I had ordered vegetarian food. What I was presented was extremely dissatisfying and not up to the mark. I pretty much did not eat entire 19 hours. For.an airline voted as best in business, it was extremely disappointing. Seats were not comfortable to sleep. Entertainment system didn’t have much choice. WiFi didn’t work for more than half the time. Cabin crew were also difficult to understand. A bit of diversity like Emirates crew would go a long way.

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

It was okay. I feel that Singapore Airlines isn't as good as it used to be but it's still not bad

It was fine. Nothing special but nothing went wrong so all good.

Overall the airline tried to give excellent service. The wheelchair service was bad at SFO. My baggage was also delayed but I thank them for taking the trouble to find it and deliver it to my home.

I felt that the whole experience went very smoothly. The aircraft was extremely clean and tidy on boarding. The cabin crew were beautifully turned out very, very efficient and were a credit to Singapore Airlines who are now my favourite carrier.

Excellent crew service. Professional, courteous. Service with a smile. Good food Very decent flight experience

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

I have paid extra money for my special meal service but I received the the local food. Which is not acceptable.

More entertainment channels and better food, whatever food requirement you select.

As I mentioned flight from NY to Bangalore was excellent but the return flight from Bahrain to NYC was mediocre, Looks like a old aircraft also not much choice in entertainment.

The flight from NY to Bangalore was very good but the return flight from Bahrain to NY was mediocre

Pretty much what you'd expect for an economy flight. The crew were excellent as usual. The food was ok, but nothing special.

Staff is rude and condescending. Airline is badly managed. They take away their flimsy earphones and blankets one hour before the lading. I’ve never experienced this with any other airline. It’s a very portly managed and run airline that should be avoided.

The Senior Flight attendant was just amazing on our Flight GF 284 on 30/11/25. She was so attentive, helpful and caring not just to us but to all in our cabin.

Loading was on time and quick Not very many people

Amazing business class in a single aisle plane. Fully flat seats, pyjamas, amenity kits, all in all a really complete product. Service was good - not amazing - but they did a good job. Got a few hours sleep. Will fly with them again if I can.

They flight was without ait conetion weather was very hot

Business class lounge for my gate was closed and no email was sent, causing me to walk back and forth to different gates, etc for over 20 minutes one way. Flight entertainment was mediocre with very poor choices especially for business class cabin. Original flight was cancelled and rebooking was difficult and no reason given for cancellation.

Very comfortable flight and simple and directed one way and back. Amazing price.

We loved our flight attendant, Emma from Scotland, the meal and entertainment offerings were wonderful, the flight was smooth, and enough leg room to stretch. We would fly with you again!

Los Angeles to London. 25th of April 2026. Business class. I was flying backwards with a complete stranger snoring next to me. In Business class. Males and females, strangers lying next to each other. Seats were backwards. I paid for comfort. I got dizziness and stress.

I liked that we got there safely. I disliked long delays, gate and ticket agents incompetence and apathy and having my luggage lost. Five days later I've yet to get anything more than a generic apology from British Air. Luggage yet to be located, much less returned.

Long line with check in at the DIA British Airway counter.

The flights were on time. Cabin crew were nice. The food was terrible! Checking in was not easy using my phone.

Crew were fantastic and the aircraft was extremely comfortable, but outdated. Headphone jacks were worn out and sound normally only came out of one ear unless positioned just right.

No problems except for a completely full flight. But we were add one because of a previous delayed flight.

The map feature on the display at the seat had challenges. The biggest issue was the flight had no WIFI. Most of the smaller planes now have free WIFI. American Airlines on the flight over had WIFI you could purchase. With 8-10 hours on a single flight, the ability to do work via WIFI is essential!!
