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

No frills airline with minimal leg room and no entertainment

I wish there was a little more leg room between the seats. The recline was good and seats overall were comfortable. I also didn’t like the 2-4-2 configuration.

The flight crew was phenominal! We couldn't have asked for any better. They were experienced professionals.

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

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.

The business class seats were very uncomfortable. When in lie flat position my legs were very restricted.

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.

All fine - you get what you pay for ! and it is a bargain

AirAsia kept us waiting for hours due to a technical issue with the plane, then eventually cancelled the flight. Unfortunately there is no-one to call or speak with at AirAsia, no customer service department at all, so I flew with another airline instead. Now I am going through the fun process of trying to get a refund from AirAsia. I strongly recommend that no-one flies with them, it's just not worth it.

The best part was Tony Fernandes actually reinstated the Buttercake menu. It has gone missing after Covid & i made a complaint in one of my Tweets back in October 2022. Both flight D170 & D171 landed very smoothly- kudos to both pilots!

The worst experience in any flight I have ever had, delayed for more than 10 hours, lost my other flight so I lost one day during my trip. Didn’t gave me facilities with my luggage either. Never again

I was next to a quite large person. Soni essentially had 2/3 of my seat for myself and couldn't sit properly. Even though there were some other seat available, the staff refuse that I occupy another seat.

Pros: The staff was very friendly. Cons: Long delay. The food is terrible.

I’m a frequent Traveler on all types of airlines, including budget. This was the worst flight experience I’ve ever had. Something was wrong with AirAsia’s systems and we were the whole flight was rescheduled to the following day, the third flight it happened to. Apart from an email which gave the new date the web and app said the original flight date which meant that there were hundreds of people queueing at the airport to try and find out what was going on. People waited six hours to talk to customer service who gave advice that didn’t match the web or app. Nightmare. just advertising for spending the extra hundred dollars I’ve ever seen.

The flight was on time, the entire experience was very smooth. The Flight crew were incredibly professional and nice. Made us feel very comfortable

Flight has no entertainment. Crew doesn't care atall. Horrible service and never going to take Air india and will spread their Horrible service.

Very bad experience luggage never made to destination no help form airlines staff aircraft was old crappy forts staff service bad airlines staff

The boarding experience was very organized and easy to follow. The flight was pleasant and the food provided was also very good. Both Delhi and Mumbai airport have metro connections which make getting around much easier.

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

I reached the check in counter 1 hour before take off and was denied boarding because the luggage could no longer be transferred to the flight. I was aback when throughout the world(including India) for a domestic flight, you need to report 1 hour before boarding. Then on top of that i was made to buy a brand new ticket. I had paid $350 for a business ticket between delhi and mumbai and then was made to buy another economy ticket for $100, No concessions/discounts were made for the airline's own inefficiency! The reservation counter was also extremely rude and unapologetic about making me pay a second time. For such a mediocre airline, there seems to be zero focus on providing good service to their customers and providing a pleasant experience.

Worst staff from Vienna. one of the server was very rude and annoying as she thinks she owns the airlines

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

very run down aircraft. seat tilted. the mobile / magazine holder was broken. The entertainment screen was not working. The crew was good, polite and helpful

Food is good, staff is good... Wi-fi quality is poor, disembarkment after landing is atrocious.
