I had the worst experience of my life in travel. Due to circumstances beyond my control (catastrophic traffic accidents on the highway between Gold Coast and Brisbane) I missed my flight for the first time ever. Because I booked through Kayak Singapore Airlines were not interested in helping me. They told me to contact the agent that I booked through. I was extremely stressed as I had connecting flights in Europe. First Kayak told me that the next available flights were in four days time. Then they told me that they could do it but at a cost of $2600 AUD. When I agreed he told me that he was having trouble getting it through Singapore’s system and he would contact me further once it had been done. When I had not heard from him after several hours, I phoned Kayak again, spoke to a different person who said he could do it for $8200. I declined and told him to cancel the booking. The worst part of this experience was that I had booked 5 flights altogether with Singapore including Premium Economy on two legs and Singapore cancelled all my flights including the return legs leaving me with having to completely reschedule my entire trip. Kayak refunded me $2000 from $5200, obviously leaving me out of pocket. This has left me feeling that I will never deal with Kayak or Singapore Airlines again.

Crew were so busy Anna so awesome. I was in a seat that got my food nearly last but the crew were Just awesome.

I find it was a bit hot before take off. If there is a way to improve the airflow it would be great

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.

Headwind delayed our flight which wasn’t the airlines fault

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.

Food could have been better. Too many passengers getting up and down all the time.

Delayed 1hour due to storm still didn't get window seat for third flight despite paying £240 extra to book them

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.

On time, friendly staff and decent food. Would definitely recommend.

Check in was awful.., Desks gone….it was a cheap chaotic environment not the usual seated staff member not there….instead a staff little platform…(staff were good) the whole thing reeked of cheap penny pinching- underwhelmed

Not at all satisfactory. I had stomach upsets after taking food. Quality of Asian vegetarian meal was awful. Further there was no snacks/ fruits/ biscuits available as in between snacks.. only peanuts and pitzels.. except courteous staff rest of my experience was far from satisfactory

I love the comfortable business class seats. The service was excellent. Staff was friendly.

The crew, pilots and flight attendants were all amazing. What could be better is reinforcing that seats cannot be reclined at departure and landing. I had a person seated in front of me who had her seat all the way inclined, including during take-off - after the crew asked her to seat upright. Cathay Pacific should reinforce this safety request and perhaps penalize those who don't follow it. I felt very unsafe with this person limiting my space and perhaps putting my life in danger in the "unlikely" case of an emergency.

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

If I had blood clots, that window seat would've killed me for certain.

I felt thirsty and asked the flight attendent for water, but no one came for more than half an hour.

The crew were fine. I didn’t enjoy the food at all. I found it unappetising and really had trouble eating it. The comfort level was fine and our return flight is with Cathay Pacific but honestly I probably wouldn’t fly Cathay Pacific again.

We requested special assistance and Cathay Pacific provided it in Sydney, but we were completely forgotten about in Hong Kong - when we really needed the help to catch our connecting flight. Really disappointing service.

The staff were excellent considering it was a jam packed flight. We had to wait nearly an hour for our baggage to appear on the carousel. That was a real shame.

The flight was delayed for almost 40 or 45 minutes. However everything was good.

They need to get in-house entertainment, also the charging stations did not charge anything, kept cutting off. So battery life was not long.

Qantas get you there, but expect them to always act in their interest over yours. On this flight basic stuff went to plan, but their promised in flight entertainment wasn't functional. Bit of an old and tired plane.

Small twin prop plane. Basic flight. Food was half a chicken & pesto sandwich. As the flight departed after 12pm alcohol was available. No on board entertainment. No wifi services.

I liked the refreshments as the flight was short and the free WiFi. The seats were comfortable.

Although the flight was delayed and out of their control, we boarded and were underway in no time. The crew were great, the service A1 and the meal was superb ( I had the chicken dish). I would fly with Qantas again, anytime. Noel Swift

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+.

Overall good experience with flight and airport wheelchair staff. Also got Indian food in the flights

Terrible. 6 hour delay with no explanations and only 15 dollars in food credits. A disaster. I'll just leave it at that.

It was so hot on the plane mixed with being quite turbulent and a rough landing. We all felt very nauseous for hours afterwards. Crew were lovely though.

I was flying business so you expect a level of comfort/support…but the staff on these flights were outstanding in their attention to detail and nothing was too difficult for them.

Overall the crew were friendlier than similar premium airlines like Cathay or Singapore. Seat was good. Food was excellent.. the starlink wifi was a real plus. The entertainment was just ok.

Very poor No information given to why we turned around.. No one at airport to help

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable

The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

I found it weird that the quality of the flight different from Australia to Doha than the Doha to Berlin leg. The quality of the toiletries pack (was in a box from Australia) and then a proper bag from Doha. The biggest variation was the inflight entertainment, which had a significantly shorter amount of content compared to the Doha flight. My QSuite seat was also broken and did not recline all the way flat. Wasn’t the best and I wouldn’t be happy if I’d paid cash for the flight.

The plane from Dublin to Doha was quite comfortable. I was in economy and the seats and rows were very tight. The man in front of me reclined his seat and it made my screen incredibly close to my face and I wasn’t able to take my tray down and my knees were pressed against the seat. I had to ask three times for him to pull his seat up but in his defence he hadn’t even reclined it far, the rows were just too close. I had a pain in my side by the end of the flight from the chairs which were quite worn and not very padded or supportive. It was a significantly inferior plane to the plane from Doha to Sydney and vice versa.

Qatar said few times that the luggage will be at the final destination but they were wrong. Please check where your port of entry is at the destination. This is where the luggage would be. The food was terrible.

I lost my baggage and it’s been three days didn’t able to find out. Also ticket was issued for qatar airways but they ended up board me on to Indigo from Doha to Hyderabad. My trip made miserable without cloths.

Flight changed to Oman air under one alliance . Seating , entertainment was not up to the quality of QR . Hope my trip back from cmb Doh will operate a QR flight instead of any other under one alliance .

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

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

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

Did not take as cancelled 3 time so took another airline

chaos boarding. Crew in business class seemed short staffed and lacking in attention to details initially, but did improve during flight.

My first course flight (Aor-Kul) was cancelled in the morning, and they asked me to board the night flight hence I need to transit overnight for the 2nd flight (Kul-Myy) that supposed to be on the same day. The overnight stay was not provided, (I'm traveling with my spouse, a daughter (5 y.o.) and an infant (2 months old). Hence I booked Sama Sama Hotel at my own expense (fortunately using my enrich miles points). Other than this issue, all services is good.

Orange juice change to mineral water . Should keep the orange juice.

Legs space in the business class cabin is too small and pillow is dirty!

I had purchased extra leg room for all legs of the flight but due to a delay in leaving Perth I was put on another flight but with Emirates. My luggage was initially lost but later found and my suitcase was broken. I ended up losing my upgrades

Personable, friendly service. Crew interactions always naturally pleasant and polite. The crew really enjoy their job and interactions with one another. Public Addresses are all smooth, clear and unambiguous - this instils confidence. Landing was butter-smooth in what seemed to be challenging and turbulent conditions - Kudos to the flight crew. Boarding and airport experience were good also.
