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.

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.

First time flying with Singapore airlines and I’ll give them two thumbs up 👍 👍

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

Good experience although the boarding gate is at the terminal extension hence need to leave lounge to head over earlier.

I'm not interested in improving the airline. Therefore, I won't explain this in more detail. Next time I'll try a different one.

The flight was mostly fine, but I really wished that seats had an outlet to charge devices considering the length of the flight (15 hours there and 14 hours back).

Although booked meal of fruit only The crew had not received this special meal The same happened on my flight Bangkok / CAN The films are so old that best is to use own computer to watch downloads . Serve nuts but they do not warm up . Service is attentive , WC clean

They used Thai Smile plane, which is a smaller model and used to service only domestic flights; hence, the plane is small and quite compact. No entertainment on the flight. While boarding was delayed, it was done in a quick manner.

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.

Could have been better. I prefer Thai airlines only but it hasnt been reliable.

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

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!

Increase the number of available films, including variety. All other aspects were great.

The crews were very professional and courteous. Pleasant flight and thank you!

We are row 11, when the crew came to us, only one meal choice was available.

OK seats comfortable, easy boarding/embarking, excellent connection to domestic Malaysia flight with baggage checked through without customs. Catering especially drinks borderline ok luckily less important aspect

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.

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.

No recognition for one World Emerald member. Business class seat has flat bed

Legs space in the business class cabin is too small and pillow is dirty!

Flight from Shanghai to Kuala Luumpur delay byy 3.5hrs with no real explanation.

I asked for more food as i was too hungry or I probably missed MAS onboard food. Both flight-attendants fulfilled my request by giving me both menus - the Nasi Lemak & the chicken noodles. Both tasted very nice. Thanks Mas. I think asked for skyjuice 5x & tomato juice twice

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.

Nice crew.flight delay fromBKK for some ground prep issue I guess, crew serve well to guest, and respect to guest as well. As usual AC is old,and nt much comert in compare to other rehional airliners.other than that.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.

When flying from Indian Sector, should be more prepared with Indian food

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.

Smooth takeoff and landing. Best service experience in all our travels over the years. Caring and attentive crew. Loved our flight to and fro.

Kayak company fake total I m not travel my payment reverse plzzz my credit card

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

Aircraft used fir this route was pretty old. Seats 💺 were hard & difficult to reclaim although it was flat bed

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!

First and the foremost I was shocked to see airindia standards have come down so low . The food was horrible . They served us 3 meals for vegetarian and all the was paneer . The orange juice was not at all cold it was smelly . After you take this heavy price air India should learn from other air lines . I at one point felt like throwing up . After all this when we landed we were not given landing slip . We had to wait for 45 min at the immigration just because no one was given landing slip . To top it all we were 3 passengers and had checked in 4 check in luggage . Out of which 3 have not yet arrived . Basically status says the loaded it in our flight ( this was a direct fight ) and it never reached . We are still waiting . There is nothing great to tell about our flight . The he only good thing was the crew were very helpful .

On time boarding, proper information, friendly and cordial approach of staff, particularly crew members and the most important timely available of checked in baggage after arrival.

Screen are not working. Windows not clean. Staff is very good. Food is okay. Experience is good. I hope the up coming is more then betters for others airlines thank you.

Flight got delayed by 3 hours but no compensation or anything

Horrible flight conditions. Entertainment system not working. Charging points not working.

Entertainment system was not available in Delhi-Ahmedabad flight. The flight was delayed for take off by 30 mins

Food could have been a lot better! Earphones worked only on one channel/earpod!

Our flight was cancelled due to technical issues. Air India staff caused each one of us to go through nightmare before finally placing us in a hotel by 2 am. I was asked to share a single room with a stranger. I insisted that I cannot share the room as I needed privacy due to my vulnerable medical situation (Heart issues, High blood pressure, High Cholesterol and Type 2 diabetics). Even after explaining my medical situation and the need for privacy, Air India instructed the hotel to charge me Rs 4000 for the room and I was forced to pay the amount at 2 am (roughly $49). Air India should refund the amount I paid for my hotel room, at the minimum. Air India didn't have any Standard Operating Procedure to do what/how/when/by whom under this situation. Mom with babies, Elderly people and people with medical condition like me were forced to wander from here to there and talk to each person right from 10pm all the way till 2am. The Air India staff didn't have PA system to give a consistent announcement, instead they were murmuring on a one-o-one basis with more than 200 passengers. It was a sight of utter mismanagement and lack of commonsense. I will not ever, I MEAN EVER TRAVEL an Air India flight even if it is free, and will not recommend Air India to anyone I care.

None of the entertainment was working. Breakfast was almost inedible. Lunch/dinner was ok. Bathrooms were fine. Staff was helpful.
