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.

Crews are not allowed to perform any service whenever the captain deems there’s a chance of turbulence. Even if it is perfectly smooth air.

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

Flight from Hong Kong to LAX was late, the plane was grubby, overcrowded and hot. I recently flew Starlux and that was a MUCH better experience.

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

Not good. Small seats. Not enough food that customers wanted. No special requests were given that i could see. Slow response from flight attendants

No proper procedures or announcements for boarding. Not even water was served on flight. Could not check in on line. This option was not available .

The crew staffs are very nice. The temperature is too low.

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.

Average flight for which I paid too much for on a last minute purchase.

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.

Poor seats. Not helpful crew. The food was awful.overall very very bad experience. Traveled with the family of 5

I was denied boarding at the Brisbane airport and it seems like I won’t get any refunds from the airline

It was great. The staff were so nice and helpful the food was great and they always made sure I was okay. As a foreigner I was worried about the language barrier but it was absolutely no issues. I highly recommend

We were diverted to Chengdu, because of bad weather and finally made it to Chong King about 7 hours later

Food was terrible. Fish was equal to a sausage and scrumbled eggs were terribly green with a quite weird fllavour. Everybody with me hated all options. The best food was the bread with butter.

I love flying Chinese airlines in general but China Southern is probably the worst of the lot. The service is poor and food is below par.

1. I got very poor check in experience with the counter lady . This is the first airline I ever experienced that no combine check in weight allow . Even we have 4 of us but weight counter by piece . So we wasted lot of time argue and repack . This is super crazy 2. Next I left my Samsung tablet on the plane . And I started to escalate and finally spoke to southern airline lost and found in Malaysia and the amazing answer she give is : system nothing found and please try to call southern airline in china 🧐 . I have been flying many other airlines but this is my first encounterment with such irresponsible airline response and no empathy given to customer . My feeling is nobody bother whether how customer like me feel and I’m just too small for the management to take note .

No red vine, no whiskey, no vodka. No that I wanted all of them at once but still...

No good but was short flight. Both of our China Southern flights were on time. No surprises.

Traveling with the Chinese airlines , their service superior to the US Airlines , they are much more friendly and the seats are comfortable , In the past I flew with United , now ,United Airline will become history for me .

Food no choice just give it seams trying to finish what ever you have in hand

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.

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

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

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

Flight from Shanghai to Kuala Luumpur delay byy 3.5hrs with no real explanation.

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

I asked for more food as i was too hungry or I probably missed MAS onboard food. Both flight-attendants fulfilled my request by giving me both menus - the Nasi Lemak & the chicken noodles. Both tasted very nice. Thanks Mas. I think asked for skyjuice 5x & tomato juice twice
