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.

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.

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

did not get a notification about seat selection ahead of time. We didn't end up sitting together.

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

In my return flight they couldn’t identify my ticket or boarding pass, I had to go to 3 different counters until I was able to get my boarding pass. The food was on, it was the bear minimum. They didn’t even recognise that I was a Muslim and can’t eat meat, chicken or pork. In one of the trays I believe they served me pork. The staff were very pleasant, but they need to be aware of their surroundings more carefully, one of them stuck her lower belly right into my face! I was shocked and very uncomfortable.

The connection between LA and Atlanta was too much stress

The crew were kind, patient and responsive. The service was excellent, even though we travelled the cheapest economy class. We arrived at our destination 40 min early, which for a 15+ hour flight is a great bonus. The boarding seemed a bit "loose", but got us boarded on time, and the plane was off exactly @ 0:30 hrs.

The airport didn‘t give me the ticket. I called customer service to ask for a refund but they kept giving me a perfunctory response and refused to refund me.

Crew: Everybody was polite. People just need to get efficient and less reworking things. Entertainment: Could have move movies and games. The “music” section is a joke, only ONE available. Food: The food provided on the flights boarding in china needs a serious reworking. Too much oil, bad for your stomach, tastes too artificial and the eggs were a giant mass of green dough.

No wheelchair service at all ( I did request that service and also purchased the priority assistant bundle) , what a waste of money

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.

Flight canceled, but they didn't notify me. They arranged a nearby hotel and 4 meals for me to stay for 24 hours before I could board.

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

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.

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

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

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

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.

Flew business class. Our luggage was the last to arrive at the belt; 15 minutes after the last bag. Sigh.
