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.

We flew business class. It was excellent. For a 6’4” individual, the seats were slightly uncomfortable for sleeping. But this is only comparison to other business class seats. Otherwise, the crew was incredibly attentive, And the service was impeccable.

The booking experience was bad. Our six character booking ID number disappeared the day before the flight, We could not find out what happened or what was the status of our flight, scheduled for the next day. We finally found the right number to contact Singapore Airlines on the matter (not easy). The Singapore agent worked through the issue in a little over thirty minutes on the phone, the day before the flight. That was great. I'm very happy with Singapore Airlines and their performance. Contact with a competent person on the matter was near impossible. It seems no one in business these days wants to deal with customers once they've pocketed the money. There were resellers, including Kayak, involved in the chain. When we finally got through to Underpricer, we did get a return call that could have proved helpful. But by that time the matter had been resolved by the Singapore agent. Majestic Vacations, the reseller who received the payment was less than worthless. That's just a fast buck operation. Ugh.

Very bad service and food variety will never come back again

My baby was with me it was really good experience with emirates

Fantastic as ever. Great staff super catering and excellent service.

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Crew were excellent and the bar service and chat fantastic. Cheese board delicious. Amenity kit good, very disappointing not getting pyjamas on this leg of the flight and needed to reuse from earlier flight.

Hospitality is good. Should improve on buggage handling because l lost a suitcase. Layover in Dubai was too long , 6 hours

Everything was superb, only bad point was that the fast track on London Heathrow arrivals was not handed out to me and I had to go back to the gate to collect it.

Superb experience. I hope they bring back the fast track option at Heathrow immigration.

I liked theAVML food. Taste was alright and quantity was enough. Sometimes during the flight I felt that the smell from toilet was coming to the cabin

You can improve in many ways First the crew in general is good, but needs to work with passion to their works not like robots Second, collecting the ear headphones long time before landing is strange The crew should deal with the passengers with respect and descent way not like giving orders

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!

Good staff, good intent, decent entertainment. More seat space would always be of benefit

More facilities to transport to the gates......felt too much walking distance

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.

Online check-in doesn't work. That's why I couldn't give it full Star.

I had never seen any cabin crews behaving like that. They are not at all professionally fit for this job

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.

It was good. Just a very long stay over in China to get the second leg to London

We were taking the flight MU 8649 from Shanghai to Osaka and the original boarding gate was 20 and we didn’t receive any notification or broadcast about gate changes, and by the time we missed the original boarding time we check thr electric board and realized the gate was changed to 208 Also the flight was delayed by almost an hour and the crew member didn’t provide any explanation, after we finally boarded the aircraft was very hot, the crew member told me the air conditioning was not working and tried to calm passages down by offering iced water, all of us sat in the aircraft for another 40 mins before it finally took off

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

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 back of the chair - premium economy could not move back - not worth the price

It was okay. Boarding the staff made you feel rushed like we were late or something

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.

We bought an upgrade to Business Class at the airport but did not realise that it was not the regular Business Class. The 787 Dreamliner was very dated with the seats not as comfortable as other airlines and some things were almost coming off. We were then told that because it was an upgrade at the airport, we get to sit in the BC cabin but will be served economy class food. So when everyone else got served in china ware, we were given the tray you got in economy class. The wifi does not work. It only connects to watch movies (which is the same as what you find in the ICE) but the internet does not work. The cabin crew while were friendly, were not responsive. Overall, I will never fly China Southern again.

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.

Quality flight from start to finish. Customer service is evidently very important to this company. The staff really exceeded expectations.

Suck! Sat in plane on the tarmac (hot) over 2 hours

It was just fine. The sirlines did live up fully to my expectation.

The flight was delayed by 2 hours, although to their credit they delayed my connecting flight so people could reach it. Also their site is a nightmare to navigate on a phone. Everything else was good.

Excellent experience however older aeroplanes used by China Eastern Airlines.

Reasonable. What they offer during the flight is not great, but the crew is polite and try to compensate it.

Price is the main attraction. Staff is OK but difficult to communicate with them due to general lack of English. Food is truly abysmal, the main courses (4) were barely edible. The choices for breakfast served at 5:30 am prior to landing at Gatwick airport were Spaghetti Bolognese or seafood fried rice. Choices offered for all 4 mains were either something rice or noodles. Shanghai airport layover is much too long in a very poorly serviced airport. We were unable to use WiFi; private lounges required cash only payment with no ATM or cash exchange open.

Good airline for the price. The Air stewardess are great, nothing is to much trouble. Will use again.

The flight was cancelled without any reason. But the next flight to Shanghai has to be cancelled to pay penalty.

You’re in the three parts of my life, the China Eastern air crew remembered and wish me happy birthday. I was given pastries on two different occasions and a complementary drink. The stew is wish me happy birthday and gave me a birthday card. Everything was first class. Thank you.

Again, I was presented with birthday pastries two times as a celebrated my birthday on both legs of my trip. I will keep flying to China using China Eastern airlines. As they made this trip a special one thank you.
