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

Never book through Kayak. They can offload booking to third parties that are completely horrible.

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

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.

No frills airline with minimal leg room and no entertainment

toilets could be cleaned more frequently, everything else was pretty good.

Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

I have difficulties to book wheelchair for my parents returned flight

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

The boarding process was awful-the computers were down and there was no way to check in. Took extremely long, very chaotic and no guarantee our bags were even getting on the plane. I was also delayed and took away from any time i had to catch a connecting flight.

Qatar Airways is an excellent service provider. The crew members were attentive and helpful. The aircraft was very clean. This was the longest leg of our journey, so it would have been nice to have more leg room for comfort. We appreciated the crew's service of four hot meals to all of us during this long flight. Also, it was helpful that the crew asked us to keep the window shades down for the entire journey, allowing the environment to get lots of rest during the trip. For families traveling with little children, this was helpful to them to keep them settled.

The boarding experience did not follow the Zones that were listed on the boarding passes. This was a two-level aircraft with many passengers. Because zones were not called out by the airline staff, there was simply a mob trying to board and it was not a pleasant experience.

This flight was a very good trip for us. The crew were very friendly and helpful. They made arrangements for my husband to have assistance in boarding. We were not expecting a meal, so it was a pleasant surprise on this short flight to have a meal and beverage from a very courteous crew.

Flight departed punctually on time. Unfortunately it seems because the destination airport is a secondary airport the airline sees it fit to operate a plane with lower comfort and offerings. There was no inflight entertainment, wifi or let alone a screen to at least track flight status for remaining flight time.

Looks like a local flight. Food was horrible. No entertainment system.

I appreciated the vailability of wheelchair services for persons with mobility issues all the way up to the aircraft. What could be better would be the food choices.

The service was good but the food was a NO

Lobster starter in business class was not good, tough, served cold, and without butter. Movie selection was missing latest releases, did not offer older classic, high quality movies

Paid $10 for wifi for full flight duration and the wifi wasn’t available after initial 2 hours

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!!

A shout-out to the flight attendent, Lauren, who was the main person assisting me. She was amazing - perfect balance of bright, cheerful, engaging, yet formal

Cramped seating but standard in all smaller aircrafts today no matter what airlines. Crew very helpful, friendly & attentive so makes up for that.

Wonderful business class flight in a lovely new plane with an excellent crew

OK, except for a cabin attendant's lack of attention.

efficient. on time. cabin crew were very professional and very nice to deal with. would definately fly BA again.

It was great overall. A few slight improvements could be made on the onboarding process at the Gates with announcements and clarity of communications (both at the gate and in flight). The movies in the entertainment options could be improved for bollywood, hollywood.

I alrady responded to this request, and expllaned at length that this was the worst flying experience in my 77 years. I will NEVER fly BA again.

Airbus A350 is poorly designed for wheelchair users and reduced mobility passengers. The angle of the pods makes it awkward to transfer. I was able to but I have ab stability. It could be a real challenge for people with more severe mobility impairments. You'd think Airbus would have come up with a solution for this or thought more about us disabled folks more when designing this aircraft.

The crew has always been great on BA. They are very friendly and accommodating. I like that they have vegetarian options already in the menu. And the free wine is a nice perk.) I noticed (both directions of my trip) minor upgrades/ replacements needed on the plane itself (touch screen didn't work with touch; bathroom light didn't go on). However, this is one of my favorite airlines.
