The usual excellent experience with Singapore Airlines. The airplane was on time and actually early to Haneda Airport. The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full. Nevertheless, the air crew were their usual outstanding standards in serving the passengers.

The onboarding experience was pleasant with no delays, perhaps owing to the fact that the flight was not full.

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.

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

Everything was great keep up the good work 😁, can't ask for more.

It was an average flight. I would have expected more from this airline. Food, seats, service, etc was just average. I just give them some extra points for offering free WiFi on board with just a Krisflyer account.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

Really enjoyed the flight. Our flight attendant on the way back SIN-LAX was exceptional I didn’t get her name but she was so kind and went above and beyond to make sure I was comfortable. I had a bit of a panic attack and she checked on me a few times to make sure I was ok. Really appreciated her attention and service. Thank u

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

Air Asia just dreadfull. Always poorest customer service and very unwelcoming staff which is clearly bread in from the Top down from the CEO

Everything was good. The red seats were a scam. Just like any other seat but red. Although they let you board earlier which was very nice.

Other than the bus wait time to off board passenger when we reached Don Muang, everything else was excellent

Very good, it would be good if payment for drinks could be accepted by card too.

Ontime, no frills, the cabin is clean, the ticket price is lower than the full-service airlines.

Paid for a meal we didn't receive. They admitted they had forgetten ours. No compensation or rectification offered. We requested if they would just give us a glass of wine instead and we would call it even. Crew advised they could not do this and to go to Air Asia counter on arrival and request a refund. Our flight didn't arrive until 2am so this was not a viable option. The crews solution was if we wanted a wine we should purchase one. I was unhappy with that suggestion considering they had already ripped us off with our meal.

Took 4 flights in 5 days 3 out of 4 left late about one hour each.

The boarding process was very poor - refueling on so rear ladder blocked. I think while boarding both ladders should be accessible so that passengers are comfortable instead of crowding through front ladder

No WiFi or movies. And the seat We’re uncomfortable. Good thing it was a short flight

It was on time! First time in a long time for Air Asia. Thank you!

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.

Did not take as cancelled 3 time so took another airline

It was a 2-hour flight so they didn't have much time for serving food. There was some turbulence so they could not serve hot coffee or tea for the safety reason. Good service, good tasting food, nice plane, a little bit of delay.

The IFE is quite unconvenient if using our own device. Not all passenger brought their own earphone/headphone.

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.

An overnight Doha to KL. Great sleep, good service and tasty food in business class

The flight has been delayed for nearly an hour, yet neither the captain nor the chief steward made an effort to explain the reason for the delay or offer any apologies to the passengers.

We recently flew with AirAsia and encountered several issues. Our flight was delayed by over an hour, and both boarding and takeoff were postponed without any prior notification. Although we eventually realized there was a delay on our own, the crew did inform us afterward. To make up for lost time, the pilot took off at high speed, resulting in some turbulent moments that were quite scary. Despite these challenges, the cabin crew did an excellent job managing the situation and easing the inconvenience. Overall, while the delays and turbulence made for a stressful experience, I appreciated the crew’s efforts to keep us as comfortable as possible.

I had a wonderful experience with this company. The staff were all very friendly and helpful. Our pilot was skilled and clearly experienced. The value for the price was excellent. I would definitely recommend them.

Very quick turn around, plane was in good condition, alles paletti.

My flight boarding was interrupted as gate staff said I needed visa in advance for Vietnam....

Instead of landing we had to go around and landed in Kuala Lumpur International Airport instead of Subang. Then we had to restart and arrived over 2.5 hrs late

As usual, poor communication on delays. No info, no updates, no apologies.

Boarding was nuts. Gate change. Delayed. No communication from gate staff. They seemed lost. Rest of the flight went well

Premium check in was worth it. Boarding process was a little chaotic. Seats were super cramped and I am less than 80kg and 180cm

It was good. The FACE check in at KLIA2 was not working.
