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.

I had selected seats together for my family of three when I first booked my tickets in February. However, I realized only when I checked in at the airport that the seats I had selected were no longer assigned to us and we were completely scattered across three different middle seats instead of being seated together! After requesting the Singapore staff to have us seated together on a full flight, they managed to find something but it was right next to the rest rooms and the whole journey of 15+ hours was really unpleasant. They said that the seat selection isn't locked and the airline can reallocate the seats anytime. No one ever told us this and it was a terribly unpleasant surprise. Will avoid Kayak/underpricer and Singapore in future

Limited food options. I dont like chicken or even fish but that’s the only option. Sad to say not impress

Subject: Complaint Regarding Cabin Temperature on Flight SQ447 (DAC–SIN)** Dear Singapore Airlines Customer Service, I am writing to express my disappointment regarding my recent experience on flight SQ447 from Dhaka (DAC) to Singapore (SIN). After boarding, it became apparent that the cabin air conditioning was not functioning adequately. When we initially raised the concern, a flight attendant informed us that it would take approximately 10 minutes for the temperature to cool down once the aircraft began operating. We trusted this explanation; however, the cabin remained uncomfortably warm, and many passengers—including my family—were sweating for an extended period. After approximately 45 minutes, I raised the issue again. While the attendant mentioned that adjustments had been made, the response did not reflect the seriousness of the ongoing discomfort. It was only after about an hour into the flight that the temperature finally improved and the cabin became more comfortable. I also spoke with several other passengers seated nearby, and they confirmed they were experiencing the same issue. As a frequent traveler who has always associated Singapore Airlines with high standards of service, this experience was very disappointing. It has made me reconsider choosing this route with your airline in the future. I hope you will review this incident and take the necessary steps to ensure that such situations are handled more promptly and professionally going forward. Thank you for your attention to this matter. Sincerely, Mohammed Shahriar

Flight attendants were awesome! Very helpful and patients. Some food were good but maybe not serving fish that kinda make the whole aircraft smell fishy. The “fried pork” was tasty but too much skin so it doesnt taste that great.

Very concerned with guest comforts going out of their way to accommodate special dietary needs when the guests hadn’t pre-ordered.

Kayak really screwed up by offloading the booking to a third party. They were completely inept and caused a bunch of toil. I will never use Kayak again.

I had ordered vegetarian food. What I was presented was extremely dissatisfying and not up to the mark. I pretty much did not eat entire 19 hours. For.an airline voted as best in business, it was extremely disappointing. Seats were not comfortable to sleep. Entertainment system didn’t have much choice. WiFi didn’t work for more than half the time. Cabin crew were also difficult to understand. A bit of diversity like Emirates crew would go a long way.

Excellent crew service. Professional, courteous. Service with a smile. Good food Very decent flight experience

As always Emirates is always dependent on the crew you get on the day and today was a good one. Everyone knew what they were doing and gracefully without hesitation . Great conversation all round even about the food and wine.

Chaos at the gate while boarding - no clear signs or announcements

Emirates First Class is always a treat with Caviar and service is always personalised.

Everything I was good except food quality is very poor

everything was great. I don't use on-board entertainment at all (I just read or sleep), but I appreciate that I couldn't hear anyone else's!

Boarding in the bus was slow and extremely hot. The flight attendant in the area of row 21 was extremely rude and had the attitude of not wanting to be at work for the day. Emirates you can do better than this

I see I gave my review for this flight on my flight Zürich to Dubai rather than Dubai to Singapore.

The individual attention the crew gives to passengers is commendable and I find them positively helpful.

service was slow, to get water had to press 4-5 times , crew come near but never notice, serving those they like to serve, hope this crew can improve their attentive ness and serve everyone respectfully.

Meals was mis-served inspite of selecting vegetarian food! I was served non- veg in both flights ie., IAD to Dubai and Dubai to Hyderabad. Staff was not that friendly

flight departure was late, with no updates on status of departure

It was ok, it felt more like an internal flight than an international flight so I guess expected a slightly better standard. Nothing really wrong with it but there was no inflight entertainment. Food and service was good.

Very good flight and very kind crew Only thing is I wish there would be a vegetarian option for the meals

Poor. Flight was delay without prior notice. Poor boarding. Poor meal service. Plane was dirty and smelly. Does not worth the money.

Overall very nice airline. The seats were cloth unlike leather seats I am accustom to on planes. The food was adequate. I had to use a paper boarding pass as they do not like electronic boarding passes. I scanned my electronic pass, but the gate agent requested the paper pass. Luckily I had a paper pass, although my electronic pass worked and when the paper pass was scanned it stated I was already on board.

The check-in process was great, and I cannot remember the name of the supervisor, but he was good and told us about the transit process very correctly and efficiently and kindly. We were given down access and the overall process was very efficient.

We boarded the plane at 1:20 pm It was hot. There was no air-conditioning It was stifling They kept us on the plane sitting there for 1 hour and 10 minutes

The most attentive crew and although we were a little late leaving ( missing passenger) flight experience more than compensated . Best flight attendants I have flown with in 50 years !!

VN661 flight, the A321 seats are starting to show heavy sign of wear and tear

The flight was delayed and changed of boarding gates without notifying the passengers; no updates on electronic boards. Everyone had to wait for a very long time and tired. No food was served even though our ticket covered a dinner set. I got to my hotel after midnight. Terrible experience with this flight

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

The crews were very professional and courteous. Pleasant flight and thank you!

AC not working, just slowly blowing room temperature air. Long taxi time does not help as well. Sweating all over the whole trip.

The IFE is quite unconvenient if using our own device. Not all passenger brought their own earphone/headphone.

Ok, but legspace on MH0127 from Kul to Per was too small. It was not possible to tilt my seat which I don't understand because the seat in front of my could do it. So I didn't rest on the flight. Also, the crew was probably understaffed because it took very long time to take trash after the meal. Everything very different from the flight with Malaysian Airlines from London to KL.

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.

The best so far coz this time it was all male steward on the economy cluster. They were polite, efficient & genuinely courteous. They do not judge you when you ask for more food & peanuts.

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

Cabin crew as always are leaps and bounds the crowning glory of MH. Friendliness and natural warmth are such incredible traits. Food was very good on this flight also; and flexibility in meal time to accomodate rest was a plus point. Early arrival and landing as the first morning inbound at T4 LHR meant I was off the plane and in the queue for an Uber in less than 15 minutes!

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.
