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

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.

Delayed for an hour. No announcement by the pilot. Cabin is very busy because it’s narrow-body.

Gate and boarding processes were handled smoothly and efficiently. Both (connecting) flights departed and arrived on time. The cabin crew seemed anxious and a bit stressed/rushed. Food service was OK, but the hot food dishes were poor quality.

HAVING ANNOUNCEMENTS FOR PEOPLE TO BOARD ACCORDING TO GROUP IS ESSENTIAL N ENSURING N CUTTING OF QUEUES, EXCEPT FOR PRIORITY CLASS PASSENGERS ON A SEPARATE Q

Delayed flight in Singapore caused the transfer at Bangkok to be very stressful. Fortunately, no elderly were in this trip, else it will not be possible to catch the connecting flight. There were also several occasions throughout the flight journey where some of the passengers were not wearing their seat belts despite several remainders from the stewardess.

It was good overall. At 6 foot 1 it's hard to say anything seat on a flight is comfortable but it would be nice to have more legroom. The meals were good but would have liked to get wine much sooner.

My case was missing a wheel on arrival Heathrow and the staff were unhelpful when i tried to get some compensation stating it was not sufficient damage, i only wish that they at some point have to deal with the same situation it put me in, maybe they would change their attitude but overall it was a good flight

The aircraft was really old, the staff demotivated and the overall United airline service is horrible

Lunch Food was tasteful and had variety. Seat was comfortable. However, when I was reserving my seats during booking, the seat configuration showed was 3-3-3, but when I boarded it was a 2-4-2 configuration? Also during booking, I had also bought travel insurance together with my TG booking. However there was no confirmation of my purchase from Allianz and TG. After several emails with TG contact, sales, reservation and Allianz was i able to confirm my insurance purchase. When the policy was issued, the birth dates of me and my wife were wrongly stated and I had to go through another round of emails with Allianz to get it corrected. Otherwise any claims would be void! It was indeed not a very good booking experience!

Check in was a disaster. 90 minutes and only 2 economy check in desks open. Had to rush to catch the flight.

After going back and forth with the airline, they never reimbursed the airline tickets. Went around asking multiple people how to get reimbursed and kept getting put back, not satisfied with their customer service.

Surprised that the safety briefing was only conducted in Malay language and no English despite there are foreigners on board. MH should take safety more seriously.

Comfortable seats in economy, managed a few hours sleep in an o night flight but the food was terrible. Surprising as Malaysia airlines has been good in the past. Service was mediocre this time too.

Vast improvement needed in customer service. I couldn’t get the drink of my choice during both meals (i.e. sparking water and Diet Coke). I had used plastic cups falling onto me from the tray. No eye contact when they thank you on the way out signalling an insincere thank you.

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

Ok, but legspace on MH0127 from Kul to Per was too small. It was not possible to tilt my seat which I don't understand because the seat in front of my could do it. So I didn't rest on the flight. Also, the crew was probably understaffed because it took very long time to take trash after the meal. Everything very different from the flight with Malaysian Airlines from London to KL.

Service / food has to be much better. Staff were not very attentive to requests. Requested for a second serve of coke and got a weird look back from the host! Was also told they don’t have extra water bottles when I requested for one before sleep! Dinner time food was very minimum and average.

Delayed, not enough information. Had to ask for refreshments, crew could have been more proactive

My experience with the flight was okay. My experience checking in was absolutely terrible. I was told I needed to change my e-ticket number to check in because I missed my flight in PDX. Even when shown the itinerary, they didn't budge and sent me to KLM across the airport. KLM wasn't open until 8pm and my flight was at 7:30pm. Nobody made accommodations in any way to get me to KUL. To add insult to injury, they rescheduled my flight to the very next day, creating a very long layover and did not offer any hotel stay. After this, even worse, I found out later they delayed the first 7:30pm flight to 9:10pm. Meaning, I could have still boarded but they refused to even try to get me on the plane. As a result, I missed a day of work and lost pay for the day. Also, when I went to get my luggage, it wasn't there. It was STILL in Singapore. They had from 5:30pm to 5am to get my luggage onto the plane and they still couldn't get that right. This is the worst experience I've had flying anywhere in the past decade I've been travelling.

Orange juice change to mineral water . Should keep the orange juice.

The flight is awful, food isn’t very tasty or good, entertainment sucks

Too many carryon bags with size of checking bags. Because of that space was not there to put carry on backpacks.

Very poor. The flight was delayed for over an hour. Also, our baggage, including that of many passengers, approimately 180 bags did not arrive, and we are yet to receive it.

From the checking, ground handlimg was very poor.seems new personal on duty,people qho suppose to be teaching them didnt see around.new people may mislead passenger, as of flt info boards, not give proper info.even informatiin counter people dont get uptodate info.makin big ques, totally disaster.guests were not happy about it.even boarding to aircraft some BC class pax sent to aft staircase, some aft pasx sent to front door.poor ground handling.may need to improove.

All good, on time, depart.only bad side was, airxraft is too old to be in business.hope ailine will manage somethinv somewhat.all good

Spesific ,Crew and cabin manager, look after all pax on board despite being in a old A320 equipment.Got free seat upgrade as well,but old style seats, no much comfert on it.But food and the spesific crew, was amazing.maintain airlanka standerd.the cabin manager, who was so much keen,keen operate as per SOP.

This leg of the trip was smoother than compared to the initial trip. Sri Lankan Airlines still have much work to do to improve the overall travel experience.

Very good crew, very efficient. Unfortunately not all items listed in duty free catalog were available.

Many changes need to be addressed from airport check in to flight departure. If they observe other major airlines, then they can expect what Sri Lankan airlines need to update their procedures.

I m not good serves poor serves I m m fake company kayak ok plzz my help my ticket cancel my tripe ok

I changed the flight, there was restriction from srilanka to india - airline is not allowing me to board with that ticket, i changed the ticket for my travel. Thanks!

Terrible airline... Originally, the flight was canceled and didn't receive a notification, had to learn from their twitter account... Rebooking was a huge pain... Every other airline like American and United did eventually fly a day later... The flight had a layover, no other airline needed one... India is such a weak nation globally, this airline has no leverage to negotiate good airspace... Flight left late, again no notifications as to why at the airport. On the plane, wifi is spotty, chargers don't work... The only saving grace used to be good food. Even that has gone down the drain. Just the worst!

They rescheduled flight..no customer care to even reach or accommodate

The plane interior was incredibly outdated. Nothing worked. My tray table was taped together (yes, TAPED!). None of the TV monitors worked. There were no buttons to turn on the overhead lights or call for a flight attendant. There was no indication of where we were or how long it would be till we got to our destination. This was a 15 hour flight btw. I was seated near the bathrooms and after a few hours on the flight, it smelled strongly of urine. It was sickening. There was only a USB charging outlet and you had to use your phone to watch movies through their WiFi. Somehow the outdated charger made it take so long to charge my devices. I paid for my seats and they definitely did a bait and switch on me. The seats I paid for were NOT the seats that I got. I will NEVER use this airline again and I highly recommend that others don't.

Ok, where do I start, hmm! Good things first - the meals/food was tasty, the seats are comfortable and legroom in Economy was ample and foot rest with message roller is simply amazing, Wi-Fi Entertainment works well. Bad things - in-flight entertainment screens and remotes either had physical damage and or simply not working. This was the case for more than 1/2 the flight. Flight that was long haul - 12+hrs non-stop. If you want a cracker or a biscuit with your tea - forget it, they carry none. Feel like having a chilled beer - forget it as they will serve you room temperature always and every time. The crew seem young and inexperienced. Will I fly again, yes I would only because it gets me from Sydney to Delhi in 12.5 odd hours (fastest), otherwise I will never. It has been what a year or so since TATA took over but I have not seen any change, I really hope this changes.

Very old plane. Broken tray tables n seats. Entertainment system super slow to operate and very little content.

Flight got delayed by 3 hours but no compensation or anything

The tv system was not working, usb was not charging . Also whole plane was stinking , this is without people , as I was one of the first to board . Complained several times

My inflight entertainment system didn’t work for the entire round trip ,16 hour flight without any inflight entertainment is tough

Food was below average. Lights were on working so could not read. Monitor were not working so could not see any entertainment. Overall very poor.

Entertainment system was broken, food was horrible, AC system was leaking. Toilets were super dirty, smelly
