Airline reviews

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.

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.

Check in was easy through self-check-in kiosks just like domestic flights. Staff onboard were fantastic. Some "book the cook" good options weren't great, others really good. Entertainment options a bit limited to what I've experienced on Qantas. Overall a good flight though, especially for the price.

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

Overall, it was a very good experience. I would have given it a 10/10, especially based on our flight from SFO to Melbourne. The cabin crew on that flight were wonderful and incredibly attentive. They took extra care when setting up our beds so we could sleep comfortably without being disturbed. Dinner was served promptly and smoothly. I woke up quite late, when the flight was already preparing for landing, and the crew still made sure I was taken care of. They brought me English tea in a proper cup, and when it was time to prepare the cabin for landing, they thoughtfully transferred it into a takeaway cup so I could continue enjoying it along with some breakfast. Those small, thoughtful gestures made the long flight feel much more comfortable and special. The service from the SFO to Melbourne crew was truly excellent.

From start to finish, every part of the experience was outstanding. The care and kindness shown to my 95-year-old mother was exceptional—truly 10 out of 10. From the assistance she received at Sydney Airport while boarding the plane to the help she was given when arriving at Wagga Wagga Airport, every staff member was friendly, professional, and genuinely caring. They made her feel comfortable, safe, and well looked after throughout her journey. A heartfelt thank you to everyone who helped make my mother's trip such a wonderful experience. Your compassion and dedication are greatly appreciated.

My flight with Qantas was excellent, the crew were exceptional, the food was very good, and the seats were surprisingly spacious and comfortable. I was extremely disappointed when my checked bag did not make it onto my connecting flight, but was pleased with the ease of filing a report of a missing bag with Qantas at the Auckland airport - there, my pleasure ended. I can see, with an apple tag on my bag, that it is still in Sydney and has not moved in more than 30 hours. I shared the tracking information with Qantas and was assured when I filed the missing bag report that my bag would be delivered first thing the next morning on the next flight from Sydney to Auckland. Qantas' missing bag tracking feature still lists its status as "searching for your bag, check back later" more than a full 24 hours after filing the report despite my having shared tracking information, a photo of the bag, and calling the customer care line and being assured that an "urgent action message" had been sent to the team in Sydney. The lack of communication from Qantas' customer service department and the lack of action after an incredibly expensive business class ticket price is outrageous and has, definitively, affected my willingness to consider flying Qantas in the future, much less on long-haul international flights with high cost airfare.

Going from Sydney to London on a single flight number was very convenient, not having to worry about changing planes. Entertainment system on A380 economy cabin is very dated. Lavatories are small. The self serve refreshments have been significantly reduced since the A380 first started.

It was ok, but not what it was like 20 years ago

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.

Ease of boarding. Staff were friendly and helpful. Food was good. In flight entertainment great.

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.

Did not take as cancelled 3 time so took another airline

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

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

Delayed for 45 minutes. Don't know what's the issue. Other than that, food was not to my satisfaction. However it's okay.

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

Entertainment system was too old, crew were unorganised during boarding

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

Check in was seamless, and easy, with friendly understanding staff and helpful Flight took off early - was good experience Meal was sub standard with only 4 pieces of chicken and container full of rice

Delayed. Poor selection onboard. Long flight and old/uncomfortable plane.

We were upgraded to better seats. No entertainment. Food mediocre

Flight was booked with a hacked credit card and flyer was allowed to board despite airline being advised. Shameful behaviour.

Due to very heavy rain in Jakarta which caused bad floods on the highways the captain kindly delayed the departure to allow many passengers to reach the plane with almost 2 hours delay. Otherwise the flight was smooth and uneventful. I was disappointed that given the long delays the passengers were not even treated to a free bottle of water. I had to buy a packet of salted peanuts and bottle of water since I missed lunch.

Liked the food. It’s was delicious! The cleanliness was average.. we saw dried liquid stains on the seat head in front. The flight was delayed. My experience with other airlines is that the flight crew usually announces an apology for the delay . Maybe air Asia doesn’t deem it necessary.. In summary the only positive that stood out was the food.

Poor booking website other travel agents are more competent. Flights on transit does not require visa

I never mad a reservation so I didn’t fly. This was fraud. Take me off your email!! 😡

Soulless machine on the boarding that doesn’t allow even 100gr of overweight. Old airplane in poor condition.

2 hours to check-in, flight delayed 90 min, no timely information. Horrible experience

A good standard flight, a little delayed, on the return flight, comfortable during cruise hour. The food was tasty, the tea pleasant, standing in the rain, on Launceston tarmac, was stupidity. Just delay the exit from the airplane, don’t have us standing around, while another plane slows its propellers. That’s common sense, but overall comfortable, clean toilet, good legroom, I paid for that, last on, first off, get a front row seat.

Smooth flight with great staff shame about the hard seats

Cabin crew were really good. Flying in to Perth from Adelaide on domestic flight. The arrival for wheel chair use however has no air bridge provided. Unloading meant a scissor lift. Otherwise a good service.

Knees in back from passenger behind, limited seat pockets, no entertainment.

The Ryanair of Australia. Not impressed. Forced me to gate check my bag as it was over their weight limit. Charged me $125 for the privilege. Then said plane hold was locked and it would have to go out in the next flight, which was the following day. Explained that I was on a cruise the next day and the plane would not arrive until after the ship left, and that it would be impossible to catch up with the cruise at any point. Lady at the gate unimpressed. So to sum up they were ready to charge me $125 to lose a bag. Finally got it resolved by appealing to management, but the whole episode was not good for the blood pressure. The gate lady said they followed the Ryanair business model which means first time passengers get penalized for doing things that other airlines routinely allow.

Although a local trip via international flight it was fairly straight forward albeit more checks than desirable for local travel. On arrival Perth collecting luggage the trollies were hidden in one end of the long hall.

Flight was fine but a domestic flight was called by Jetstar international. This meant going through immigration and custom scanning twice. Long queues were experienced which were frustrating. We were using a wheelchair and exit at Perth needed a scissor lift as no air bridge provided. No fast lane at Perth for wheelchair. The staff were helpful but this system is poor.

Unaware of charge for carry on until i got to gate

I like that fare is cheap but because there's no amenities whatsoever. You get what you paid for.

Note that food has to be purchased in flight. No free food. And no entertainment in flight. So I’ve treated these two items as okay which, in this case, means neutral/not applicable.
