Airline reviews

Food was served to different people at different times and it wasn't clear why. The crew apologized for the wait. But it felt odd and inconsistent. They could use charging ports on each of the seats. Mine didn't have any. Also, they could've offered more snacks. It was a 12+ hour flight and no snacks were ever offered. Everything else was OK.

Mine didn't have any. Also, they could've offered more snacks. It was a 12+ hour flight and no snacks were ever offered. Everything else was OK.

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

toilets could be cleaned more frequently, everything else was pretty good.

Pleasant business class flight experience with good onboarding experience. Flight service team was excellent with usual book-the-chef menu available

a completely full flight - felt quite carmped in, despite being on the window seat. Meal served could better. Surely different from pre-covid trips I used to take to and from Bangkok.

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

SQ service is great as always. However, the food quality seems to have gotten a lot worse recently.

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

Wish the seat don’t have restrictions, can’t fully insert backpack all the way inside.

Airline should consider adding a small meal at the last leg of the flight, right now there is 7 hours of no meal break.

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.

Except that our flight was cancelled, by mail, and later moved to 12 hours prior, then the experience was good. In Bangkok we were offered a hotel, it was fine, but would have been nice to know in advance😉

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).

Given the Business class airfare, the food variety and quality both were substandard. The crew was not interested to serve other choices and work hard to provide alternatives. Very disappointing food service.

The experience was efficient, on time, and provided great service.

My flight was suppose to be at 7:45pm to fly but it didnt fly out until 8:55 to dallas so then all of my other flights was late and delay ihad to wait at the airport for extra 14 hours to be able to get on a different plane

There were delays at boarding and landing. These events resulted in a tight transfer time in HK. Poor signage for transfers. Finally, lost luggage at final destination.

It was good. The planes needed to be updated though, they were dated and the entertainment systems were old. Service was amazing. The pre-booked meals were lacklustre.

Well- trained, cheerful onboard staff. Business class seating and storage were excellent. Outstanding range of food choices, though quality ranged from just OK (seasonal rice and beef dish) to outstanding ( congee and soup noodles with beef brisket). But what can you expect; it's on a plane. I couldn't figure out the remote control, but touch screen worked well. My wife and I (in our 60s), didnt find much to watch from the Entertainment choices. We mostly watched the flight maps. The bedding did the job but is unwieldy and ends up in a clump, with one-third falling on the floor.

The staff were so friendly and accommodating. The food was great. Lots of movies to choose from as well as tv shows. Highly recommend.

The lead business class attendant was excellent. Made a point of greeting you and knowing your name by the time you leave.

My connecting flight was canceled or never existed. My stopover went from 1 hour and a half to 10 hours. It was a long day that I wasn't prepared for and it would have been nice to know that ahead of time. Cathay is great though. Great staff, entertainment and food.

Overall pretty good experience. It would be nice to have caught the attendants even they were flying down the aisle with snacks, and if they could cater to multiple dietary restrictions (bland and no lactose. The customer service chat is a bad experience), but otherwise no complaints.

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.

Jia yung was the flight attendant that made this a miserable flight.

The flight isn’t great, as the plane has faulty with light and noise. It blinks and make noise for 8hrs non stop! Causing health and sensory issues! Causing Hazard matter to all 3 babies that on bassinet seats. This matters affected 12 passengers and the most horrible flight I ever experience. Have been flying with MAS for more 30yrs and this is the worst! Very disappointed

Bad weather in Amritsar cancelled the flight while we were at the gate in Delhi but the ground crew took good care of us and exceeded our expectations. Once on the plane, we enjoyed the best experience we’ve had on any flight in years. Their customer support was also impressively quick to answer and immediately helpful.

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

Overall it was good. But air planes should be upgraded.

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

Boarding was through bus even though aerobridges were empty. Major mess

Uneventful trip. Good flight crew. Food could have been better and a bit more of it. Cabin cleanliness was ok.

Too many changes in departure time (4-5 times before the actual departure time was determined) with no reasons provided.

Terrible. Air India canceled my flight out of Kathmandu because of airport constructions but did not tell me. They should not be selling night flights out of Kathmandu right now that they know they will not honor. The staff was terrible and not helpful with my rebooking or compensating me.

Good experience, comfortable seats. Entertainment did not work but vista wifi and entertainment worked great.

Flight leg to and from IAD/Delhi was good. The leg to and from Delhi/KTM was terrible.
