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.

A little more room from the reclining seat in the front of me.

It was okay. I feel that Singapore Airlines isn't as good as it used to be but it's still not bad

It was fine. Nothing special but nothing went wrong so all good.

Overall the airline tried to give excellent service. The wheelchair service was bad at SFO. My baggage was also delayed but I thank them for taking the trouble to find it and deliver it to my home.

It was perfect! United Airlines staff was extremely caring, super friendly and professional

United has maintenance issues and can then never recover. No operations ability and simple issues always turn into multiple hours long cascading delays. Worst airline on earth.

I paid for a confirmed upgraded aisle seat and was moved to a center seat in the back of the plane at the last minute.

Horrifying Almost 2 million miles. Bring your own food and drink. One coffee or drink every three hours. Have to order meals on app more than 24 hours ahead Tiny and dirty bathrooms

Easy of boarding, helpfully staff at check in, surprisingly comfortable seating

Lost of requested seat assignments. Lost my husband's meal choice

My service dog and I were asked to deplane just before they closed the door - clearly very last minute they couldn’t find the documentation that I have filled out many many times before that is for flying service animals. I purposely purchase 3seats (a whole row) since he is large and not all passengers want to sit next to a dog on a cross country flight. The plane departed with my husband on it!!! They made me fill out a hard copy of the same form and had to reschedule me on a later flight where they could find 3 seats together!! I’ve done this so many times before - clearly the error was on their part in a technology glitch - but really people - do better!! Very traumatic - and my husband had to wait for us when he landed ….so bad. Poor pup was confused and tired.

My flight time was changed without any notification to me which ruined my time sensitive plans so I ended up completely changing my travel plans and no reimbursement.

No screens or meal options. Freezing cold. Dirty seats. Left late.

I liked that my son and I were reseated next to each other (we had different bookings). I liked that it was a directg flight and mostly on time. I liked that you provided pillows and blankets. Flight attendants were generally courteous. The messaging through wifi did not work well. The food was not good. Seats are very narrow and I felt slightly claustraphobic in the window seat.
