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

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.

Everything was great except the boarding experience. After the check in, they "packed us" in a small area, very hot there. It would be nice to be aware of this, I'd wait on the outside area

Mostly good and consistent of Emirates service. Christmas menu was great initiative and tasted good. Taking the bus from terminal to the plane spoilt the experience a little.

Delayed and missed connecting flight. But Emirates took care until next day flight. Thank you

The best ever, friendly and attentive cabin crew, amazing captains who utilised their expertise for less turbulence, just overall amazing

The lounge staff at reception were inefficient and robotic. Boarding process was chaotic at the gate with no priority for business and first. At arrival into Dubai, no upper deck door . Food option and quality for this flight was awful . Thankfully the bar is always good.

The staff were very friendly and helpful. The seats were very comfortable and spacious. The entertainment was amazing, and so was the food!

On the DXB to IAD flight, missed the snack between the meals again...

Worst ever. No assistance and communication from Emirates crew. No visibility of when the flight is flying. Couldn’t understand if we can go to lounge to take rest. Emirates system at a certain point said flight is not operating and suggested to take the next flight and in few minutes it suddenly opened the gate for boarding. unsupportive and rude crew. Worst experience ever. Flight was delayed by 5 hours so need the compensation for that.

The amenities offered in the Business class is far away less compared with other Air Companies. Emirates is going down in the competition pricing the same value as Qatar airways for example.

Everything was excellent! It would be nice to have a slightly bigger seat

When getting to our seats a blanket, headphones and pillow where there already. The food was very good and plentiful. I liked when they came around w/hot towels to freshen up with. Slippers, socks and an eye mask was a nice surprise. My husband and I have mobility issues and the transporters were absolutely wonderful and helpful w/the wheelchairs at each stop. Getting from one gate to the next they were a blessing.

Alright. I don’t like the boarding process. Gate staff shout out in Turkish where to line up etc. no microphone used. You can’t hear it. No English translation. It’s a bit archaic!

Boarding started too early stuck standing in the security corral for 1 hour with no update on when to board

As usual. The perfect flight. Keep it like it is

787-9 TOO OLD AIRCRAFT , MY SEAT BELT INCORRECTLY FIXED, THE TRAY TABLE SLIDING, REPORTED BOTH , NO CURTESY BY CABIN MANAGER TO APOLOGIZE AT LEAST . FOOD WAS OVERCOOKED : THE PRESENCE OF A CHEF IS JUST A PROMOTIONAL PLOY , WINES EXCELLENT . THE FARE COST IS EQUIVALENT TO QUATAR , BUT TK IS FAR FROM MATCHING THEIR LEVEL BOTH BY AIRCRAFT , FOOD AND SERVICE .. I WOULD NOT TRAVEL BUSINESS WITH TK ANY LONGER .

Entertainment was good. Flight was delayed, nearly missed my connecting flight. The gate was changed on several occasions. My luggage did not arrive on time and had to leave without it.

Flight Singapore - Istanbul was perfect. Flight Istanbul - Sao Paolo - Buenos Aires was really good but there was a big delay in Sao Paolo (Brazil) due to a problem with the ground staff and not related to Turkish Airline. Overall a very good and solid experience

The fully flat bed in business class on the 777 is a little narrow, and the 2-3-2 configuration is now dated, but otherwise a comfortable and pleasant flight. It’s hard to beat the value too.

This time around, I felt that the crew wasn’t very professional. Speaking / laughing loudly and rushing through service.

I canceled this flight after turkish airlines did not provide any consideration for a death in the family while in Singapore

The plane cleanness, punctuality and crew attention was great. The airline is offering free fast wifi on the flight, however apparently without much policy on the use. Quite a few passengers felt the liberty to watch shorts or other content without headphones from their devices as well as talking for long durations over phone calls. This made a 4-hour, fully booked flight somehow difficult to bear.

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.

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

Flight was fine overall. What you would expect from economy seats. I did appreciate the amenities (eyemask, earplugs, small toothbrush and toothpaste, thin socks).

Was required to print a boarding pass, which I'd prefer to avoid. Seat (economy x) was comfortable, service was excellent.

Asian Veng meal have Non Veg items which is not ok. Pure veg meals option are too less and they have inclusion of Vedgan and Lactos etc... which is taste less

The business class experience was awesome - I will be using QATAR airways again and it'll be business class again - appreciate the privileges afforded to the business class clients - thank you.

Luggage handling was very very bad. Damaged my new Calvin Klein bag and delayed another. Still did not get it since 2 days. Worst airlines and service.

My Tv don’t work the whole from Doha to New Delhi. Overnight didn’t work from Bos to Doha and had to eat food without light

The seats did not have foot rest. If there is no foot rest you can’t sleep.

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

The boarding was late. The check-in board said boarding closed but the boarding hadn't even started. I have spine issue but not eligible for wheelchair since I can walk. But we were taken to a plane with stairs to climb. I requested support with the handcarry and was told that I shouldn't have booked this flight without wheelchair. Instead this information should be public if this plane has sky bridge or stairs. The infotainment system did not work either. And the plane was very loud with very less legroom in economy.

Very poor experience, passengers and were not social and started a troubled with other passengers and a fight erupted

Had to discuss more than 15 min regarding wheelchair they gave only at the start location. No food serv in 1 st flight. Considering flight started at 10:00 pm so had to starve for dinner. Checkin screw was polite. Food in 2 nd and 3 rd flights was not good. It was too cold in the flights. Had to ask for blankets. Missed quality all thru, though the fare was on higher side

Food could have been better Entertainment was absent even in Business Class

Gulfair were on top form and everything went as planned

The entertainment on board was really poor. The map doesn’t give enough information and the movies have arabic subtitles, you can’t choose. The stuff wasn’t very friendly and the breakfast really poor. The food must not be spicy! They didn’t have enough drinks.

Aircraft was new and comfertable .on time. Cabin crews, which I got english language pronounce was very difficult to understand .ovee all ok flight

Few people on the plane - Was great! The plane was late to board and over an hour late to arrive. They said it was airport control. How can these things not be booked it advance? Very frustrating!

The flight was a transit and I had my boarding pass from the departure. I have talked to the check in person to set me up close to my family seats and ended up with my wife in one seat, 3 years old son in different seat and myself on different seat. very disappointing and overwhelming.
