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.

Best airline I think. No problems with anything. Crew were great, no problems with the airline food and entertainment and a smooth flight.

Service was top notch and the attention to passengers is great. Takeoff and landing was on schedule. Food selection is good

Lounge a access was excellent as was the attentiveness and service from the crew as always. The food and drink supplied were of good quality. The entertainment system had a good selection and I liked the mapping system supplied. However the screen wild have been bigger and the operation a little smoother to navigate. The seats were barely comfortable, but adequate.

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Headwind delayed our flight which wasn’t the airlines fault

Good service and food. For buying items on flight should be preordered as they don’t keep much stock on board.

We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

Horrendous. We upgraded and they took the money but cancelled one of our tickets. The recline action didn’t work on the seats for the flight from Singapore to London, pre booked meals but they seemed to have disappeared as well.. Phone customer service was horrendous. Took 5 phone calls and no fix. Craig at the airport was the only one who seemed to be able to get the ticket back.

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

The flight was just ok, but the vendor made it exceptio ally bard to manage my own reservation and would not give me access. The blocked all of the one time pins to come to their email address which caused me.to go through them eceryrime to get seats see rhe reservation and even get wheelchair access for my sick 71 year old uncle. They only xommunicates via a bot which gave me incorrect info. I thought this was Kayak and not underprivileged. They ruined his trip, did not get him aisle seats and made it impossible to purchase extra leg room. It was a horrible experience. He was taken to hospital on arrival only to find he had blood clots and pnemonia while trying to navigate the airport. This vendor is very irresponsible and the airline could not access his info.

The morning in Hong Kong was ridiculous. Very chaotic. The flight was delayed. Missed connecting flights. Kathy should be more competent in getting the planes ready ahead of time so that flights can depart on time.. totally ridiculous and unnecessary. Very poor performance.

Chicken pieces were too big with pasta. Need to be smaller.

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.

they are deley vancouver to hankong 3 hour after honkong 20 hour stay there honkong not visa approved and they cant help to visa so we are stay in airport 20 hour even honkong staf very bad person they cant do for us 6 hour we arround they said you there you go there waste time next time i dont want to go cathay stay in honkong

I was only given 2 meals, and my screen showed that there were 3 meals. Second meal was 1-2 hours late according to the screen.

Just want to do a little more clean up so does not smell like urine.

Entertainment for kids was good. Good was terrible, needs lots of work.

As before, my only problem was not being able to download my boarding passes prior to arrival at the airport. Everything else was perfect.

Flight was canceled. I was not alerted. It was only kayak that alerted me

Flight was 2.5 hours late leaving. We spent 50 minutes of that sitting on the plane with no explanation. They did reduce the time in the air so we arrived a little less late which was something. The cheese and crackers were okay but the wine was terrible.

Excellent as always, I won't fly to Australia, and back to the US on any other airline. The flight crew is always top notch, and have a way to make one feel extra special. Thank you for your service, I would rate Qantas Airways a 10+.

Basic airline, aircraft and service. AA gets you from point A to B. My flight was delayed by 2 hours too.

No internet on flight, which makes log travels really hard.

Not great. The inflight entertainment was all on an app, and I did not want to watch a film on my phone. Also, the range of options of films was limited.

by the time they got to our row, they were out of some of the food options. games and movies were great but maybe more game options like tetris or pac man would be great

A few more inches of legroom is all i ask

Great as usual, some delays but well communicated and made up for in the air

Business class points redemption - good value for points paid, dubious value if out of your own pocket, domestic class business product okay for this length of flight. The flight left and arrived on time, crew were good, aircraft was a bit old and tired, but still miles ahead of their competitors in Virgin and Jetstar.

I missed my flight ,staff unhelpful, they sat and watched me wait ,gangway door closed, English was a problem no announcement I was on time now I missed my month vacation ,lost 1400 bucks no refund I'm sick to my stomach

Seat space was tight and uncomfortable. There was hardly any cushioning giving me a terrible tail bone ache. Getting and out was extremely cramped. We paid for seat choices and felt totally ripped off. Food was mediocre. By the time the servers served 2 or 3 rows they ran out of this or that option as we saw on the inbound trip also. This is infuriating. Entertainment choices were extremely limited for such a long haul. The screen froze on occasion and did not switch off when the on off button was pressed. When it did it came back on its own in 5 seconds. The airlines has gone downhill since last year.

excellent, staff and boarding were all seamless and no issues, thank you!

More leg space than other flights, but felt like *maybe* narrower seats?

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

Same problem place in the middle so small Im 1,85 m so not good 👍

The WiFi was not compatible on both my phones (Vivo Y30 5g and Samsung Galaxy A32) with up-to-date android software.

Stewardess was attentive and was actively roamin to check the passengers on the biz class

It was worst flight ever of 26h. Poor service and seating. Flight from Abu Dhabi to Islamabad service and seating was worst ever. No tv extra.

It was OK as the seat which we paid for doesn’t have any window. We paid $120 for 3 seats but it’s for nothing. Crew could not help. None of the ports worked so all our phones went dry

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

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