Had picked seats while booking tickets but airlines reshuffled the seats without informing and we were again left with the worst possible seats on the return journey. terrible experience.

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.

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.

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

Flight was delayed by and hour but were informed beforehand

Boarding, seats, entertainment and service were all great. Food was great except for the fact that there were too many sweet items.

The service on board was excellent, the flight wasn’t overbooked and we departed and arrived on time.

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!

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

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.

It was also a great experience except to the inconvenience of connecting flights since we need to took buses to go to another terminal and the boarding was easy but if you manage to find the terminal in time. Still it was a great experience with Kayak and Emirates.

I booked the air tickets through Kayak for traveling to India. I wasn't sure how to tackle the ticket booking process but it was so much easy with the Kayak , Surprisingly I even found the Indian branch of Kayak which I used for the domestic travel. All in all , it's most convenient site to use here as well as abroad. I will definitely use Kayak for my future travels.
