The staff was great. I also like the movie selection was great. Lastly, it I appreciated the fact that wine was a drink selection.

It is not so much I had bad experience with Singapore Airlines, but with Kayak and particularly Underpricer. My wife and my seat arrangements were changed some times after we booked our tickets and reserved our seats I February 14, 2026. However, after our arrival we realized that we were separated and sitting in different isles. Our return tickets indicated the same. Our several calls to your Underpricer customer care were useless as they cared how much they could charge us rather than actually help us. At the end they referred us to Singapore Airlines. If that was the solution, why did I have to call your Underpricer customer care. I will definitely erase your app from my phone and I will never use Kayak for future traveling. After all, there are so many agencies that I can use other than your company.

It was good but n it to the same standard as London to Singapore

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

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.

On the way there the food was not a good Standerd and fly Dubai is very cramped and again the food was not a good Standerd but on the way back food was excellent and staff were very helpful specially a lady which I took time to take her name Maria and another staff which was South African very very polite and helpful i am very sorry that I got her name

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.

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

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.

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

The wifi was out. Otherwise it was great flight. Richard, as CSM, was excellent.

Planes was old - business class seats looked like they were installed in the 80s

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

Awful , hidden charges for the luggage was a very awful thing, very much a scam , booking the flight thinking the luggage was included was definitely a scam , then the girl that was taking my luggage Ayrlease the airport was an absolute awful , telling me if I don’t have money to take my luggage with me I can just throw it away , how professional, NEVER AGAIN .

Maybe some more information as to why the flight got delayed I understand may be tell your customers that missiles were fired at a specific airport wouldn't be reassuring to the customers and would cause mayhem but something like recent events have cause a delay on your flight or smth

From the start of my vacation at Logan Airport, Boston it was chaotic. I'm praying my flight home is better .I'm grateful that we landed safe

Kayak and Aran grant issuing business class tickets without lounge access and sometimes 1 or 2 connections in economy class. It’s very disappointing to find out that after buying the ticket. Never buy tickets on kayak and Aran grant again

we were delayed from Athens to Abu Dhabi by an hour and a half, so I had trouble connecting the flight from there to Bali. It could have been done had they waited even 15 mins. There was another lady who was in the same boat. By the time we were half way across the terminal, they have actually already issued different flights for us to go Jakarta then to Bali. Not to mention the inconvenience of waiting over 4 hrs at the airport and the subsequent inconvenience, we did not arrive to Bali till after 800pm the next day, which means I paid for the hotel for nothing when I could have been there before noon the next day! There was little explanation. It was just as well I needed some assistance getting around, otherwise the 2 of us would have been completely lost! Not going to fly with them again!

Good range of movies but lacking decent tv shows. Wifi was really expensive on this flight, considering flights under 7 hours have a $9.99 USD charge for streaming, to jump up to $24.99 for a 7 hour 40 flight seemed a little bit of a rip off. Staff are inattentive, and really need to improve on the customer experience. The new airport is fantastic, as is the new lounge, a huge upgrade from the old airport and lounge!

Etihad broke my suitcase Also over charged me for luggage

Crew member took too long time to take back leftover food plates from passenger seats. Food was nice.Easy excellent checking.Guy at checking counter was really kind and helpful.Made our checking very quickly. Leftover food should be taken back ASAP. Because in economy class passanger have narrow space . In the long journey like this, passanger have difficulties to sit with the plates.overall experience was good.

Crew was good, boarding mediocre, food choices were limited, seating was not comfortable

I could not book in online at all which is what I always do to secure a window seat which is my preference.

I really enjoyed the flight…and food and the hospitality but didn’t get the food I requested for.

Everything was terrific. Kevin, and the whole crew, were exceptional. Five stars all around! Thanks so much.

Flight held at gate for other passengers. We ended up being late and missed connection

Should have more cosmopolitan food choices - too many Indian dishes - the only entree not Indian was lamb which I don't eat

The plane was ancient, and its technology was in disrepair. None of the charging stations worked, and the screens were barely functioning.

Worst thing: Luggage took forever to get at LAX despite priority bags. Best: Flight attendants were great!

It was my experience w Kayak that was negative. I’m never using kayak again

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.
