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.

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

Very bad service and food variety will never come back again

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

It was ok, but not what it was like 20 years ago

I missed my flight due to unforeseen circumstances It was, however , an excellent price !

This was the worst flight I’ve been on. Getting on the plane where is was 30 degrees outside was hotter on board cabin must’ve been 33 degrees. This is a health hazard. They cannot be doing this to save on fuel. People could die from this!!. Fans and a/c was, off entertainment was off. Poor excuse given. Crew made the excuse that the system didn’t have enough power. They basically were operating on one engine to save on jet fuel till 3 hours later on cruising altitude and they then started the second engine. And finally the cabin was cooled. On a 7hour red eye flight this made it so uncomfortable and impossible to sleep.

Headphone jacks worked poorly, seat recline was broken. Planes were rundown.

The flight was good, long obviously but smooth. The seats are pretty small, definitely notice a difference for long haul compared to Emirates or Cathay Pacific it’s more like medium haul seating for space. Food options were good, children’s meals were good for my fussy 3yo.

The flight was delayed over 2 hours. We had to wait on the plane and the air conditioning was turned off. The food was average and the cutlery was wooden!

flight delayed, wait in crowded gate. staff inattentive. had to remind them to get my coat from their closet. not many new movies, media choices were limited (nothing compared to Emirates.) Lounge was crowded

Old plane nothing worked no charging facilities for phones etc

New month and no new movies. Qantas has lost the plot

Left rather late but did the best to make up time..

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

There was frequent beverage ,meal and snack service. The crew was very hospitable and professional.

Being a platinum member, no attention given. No towel or tissue provided.

Good staff, good intent, decent entertainment. More seat space would always be of benefit

No towels or tissue and chocolate and mint provided before arrival

Staff was helpful. Flight was on time. Overall excellent experience. Thank you will fly again.

Each and every requirement was nicely provided by all staff no very be happy

BLR boarding is total pathetic. Should not fly Qatar from Bengaluru. Check in staff is too rude there

I didn’t expect American Airlines. I excepted QTAR AIR LINES. From KAYAK we are booking so in the kayak site it showed qathar air lines but operating American Airlines. I don’t like .

The screen was not clean.It had stains of previous customer .Also the toilets..My daughter got urine infection. Not happy with the cleanliness of aircraft.Also requested multiple time hot beverages but not served at all sighting disturbances. Request on behalf of every passenger please sanitize and clean as we stay for 15 plus hours..

Boarding was seamless, crew were great. Less disruptions on the night flight would have improved the experience and turning off lights earlier.

Worst customer service I've ever experienced on a flight. They downgraded my seat without giving me any other options, then sat in a seat with an arched back for 10 hours. I was not able to get ahold of any customer service representatives to understand what alternatives I might have, or how they will be handling a refund for the difference in fares between business and premium economy that I was downgraded to.

British airways needs to improve their luggage handling process and communications. The luggage was lost/left in UK. But, this was not communicated to me as a traveler and because of the wait at the carousel in Seattle (we have to go through customs and immigration on arrival to US) I missed the connecting flight and had to be rebooked. No one informed me that the luggage wasn't there, and there was no one there at the carousel to check with or help me get through security faster. I wasn't the only one- there were a lot of people waiting for luggage that didn't arrive.

My bags were lost. I waited in a line for 5 hours after I landed and got no resolution to the issue.

Easily one of the best flights I’ve ever taken. Worth it to upgrade slightly. Crew was phenomenal. Just wish the man sat next to me kept his shoes on. There should be a rule about that. But I wish I could take every flight with BA.

Poor experience at Bengaluru Airport. Slow check-in process. Boarding calls were unclear and by number (no clarification given for priority groups) and were caught in wrong queue with infant based on what was written on ticket. Aircraft seat was not comfortable. Slow initial service for flight at 03:00 where most passengers wanted to sleep - did not seem right to be serving meal after takeoff. Poor quality breakfast in morning, not offered any tea/coffee alongside Only saving grace was that this was a night flight and the plane had free high-speed Starlink wifi.

Great flight, great crew, decent food. Premium Economy was very comfortable. I compare this flight to the one we took on BA from DC to London: Like a different airline. The food was atrocious, the crew aloof, and the cabin not as comfortable. Based on that first flight we said we'd avoid BA, but the return trip changed our minds.

Bad. After 3 hours on tarmac, flight got cancelled. No assistance whatsoever from BA.

Much better than from Singapore to London, which was awful. London to ORD was business class experience expected. Friendly and helpful flight attendants, decent main course, delicious dessert, comfortable lay flat private seats.

The "new" configuration Club class provides a fantastic experience - a private pod, with great design and plenty of room to spread out. In addition, the cabin service was beyond excellent, and the food was great. Thank you for this sector, BA - it was worth every penny.
