Never book through Kayak. They can offload booking to third parties that are completely horrible.

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

Excellent service. I pre-ordered gluten intolerant meal and they handle it with care. They served me my meal before other people's to avoid crossed contamination. Thank you 🙏

No frills airline with minimal leg room and no entertainment

The flight arrived on time. 2×2 seating meant no one needed to sit in the middle. This was a connectibf flight from Singapore and required going to 3 counters in different levels to check a golf bag

Food was just okay, need to improve for other menu variations

The consistency with Singapore Airlines is fantastic. Crew are always brilliant and food delicious in business class

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

We still get drinks and a snack. Love the gift bags too.

business class is old but still done very well by the team.

Excellent airline. The plane was clean and the staff were very attentive

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

Thai Royal First is very good. Easy check in , Private room in the first class lounge and escort from ticketing to the plane. Once on board crew was very polite, food was outstanding, and the ride was smooth as silk. Restrooms were especially clean. Great Experience

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 (boarding) was delayed by 40-50 minutes and there was very crowed. They need to improve on the timeliness & boarding process. (They asked passenger to board in groups, but the 2nd group was standing there waiting for 20 minutes!). However, services from the crew was very good, also the food was good as well. I also found the legroom was quite comfortable.

Need to improve on punctuality. My flight was delayed by 1 hour.

Seats were uncomfortable and the vegetarian meal was awful. Some of the entertainment didn't work.

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

They wouldn't let me on the plane. The 3rd party apparently didn't pay for the tickets properly?

Overall experience is good but if the food menu can change to authentic Malaysia food will be good. I.e. Nasi Lemak, Char Kueh Tiew and etc

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.

Flights were delayed, Food was good but only 1 meal instead of 2.

Food was good but only 1 meal and 1 pie, instead of 2 meals. Both legs were late.

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

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.

I was pretty sure my seat includes a meal. But I guess I was wrong because I wasn't served a meal on my flight with Batik Air from Kota Kinabalu to Kuala Lumpur. I was fortunate because the layover was more than an hour in Kuala Lumpur. Otherwise, I could have cause a delay to the connecting flight to Taiwan because my terminal to board the next flight is located at different building. I had to take a train to the satellite building. Overall, all is well.

Freezing onboard and staff refused to give me hot water “because we were landing soon”. The plane arrived at the gate an hour late. And there’s an air leak in one of the bathrooms. Very scary noise.

Batik Air is racing to the bottom of the list with its consistent flight delays. Especially out of Malaysia. Shocking that they keep getting away with it without any form of punishment from the authorities. Also very inconsistent rules on cabin luggage.

Need to improve the availability of the food. Seems like everything sold out

Did not like that we were not informed about the 4 hour delay, crew not friendly, noone at terminals to consult with...all employees for Batrik were behind glass aftervgoing through security at the gate again. Why no agent at Gate H 10 to answer questions? And no apology. Updates would have eased anxiety. Boarding is disorderly also.

During this flight all the crew just focused on making money by selling food and drinks. There was only one washroom open. And it really smelled bad and wasn’t usable. Even to watch something onboard entertainment u have to rent headphones pathetic airline but only one with direct flight so pretty much the only option from Karachi to KL

Delayed for 3 hours, need to pay extra for drinking water.

The OD2204 KUL-LGK was delayed 40 minutes due to air-condition malfuntion, after inspection the technician give green light for the flight to go as usual but the air-condition is still not working properly, passengers complaining to the stewardess but they cannot do anything, I did tweet to @malindoair to complaint but no reply from them … hope this Batik Air is not having problem like Rayani Air and I do hope the management do respond to my complaint as well

Nasi lemak was horrible. Plain white rice, tasteless sambal, no cucumber, no kacang, no ikan bilis. And the chicken was colourless and tasteless, tasted like boiled chicken. Entertainment system didn't work at all.

2 delayed flights - hotel layover in a different country- lost baggage.

Poor, pilot flew as if he was in hurry and had to coverup for wasted time

Crew was polite. Ground crew was prompt in informing about the flight delay. Boarding process was ok. There was no entertainment on the flight. Blankets were not available for an overnight flight. It was very cold & blanket was given upon request. Food was average. It would have been better to serve breakfast instead of a late night dinner as people like to sleep & serving breakfast before disembarking in the morning at Singapore would have been much appreciated. Seats were ok. Plane was old.

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!

Never ever travel with Air India is a very conscious promise made to myself. Poor customer service , irresponsible staff, pathetic operations and bad planes. Overall -0/10. Planes had mosquitoes in it.. i am still thinking what international standards of hygiene are they even following????. Operations team has no quality standards. They can route you anywhere on any plane inspite of a confirmed ticket and a web checkin… without your consent. Go for AirIndia if you love challenges and roller coasters and safety, time and hygiene is never your priority.

Flight was delayed in phases from 84ppm to 2am. And at 2am it was cancelled. Only refund option provided and no stay was provided. Poor communication throughout and shameless behaviour from the airline with no regard for seniors citizens and those travelling with children.

Food, choice of menu and quantity were poor. Crew services were even poorer, not attending call bittons

Undisputed leader in sky for Indians. Very good crew right from ground to mid sky. Very sumptuous meals twice

There’s no comparison for new avatar of air India. Long live Air India. Amazing hospitality and ultra soft polite charming crew

We had extra baggage which is an ordinary event. The check-in counter experience for them to calculate the additional amount owed and collect payment was terrible - very manual, multiple counters to resolve, took more than 30 minutes

my experience with kayak was terrible. Team kayak just left me with a booking and limbo and preffered not to contact me.. Instead when I contacted the team they said the booking is cancelled. Seriously 5 days after booking u were waiting of my call to inform me of the incompetence of the team. This will be taken up with higher authorities
