For employees who speak English just slow down...the accent when spoken fast is difficult to understand at first.

Leaving Vietnam through customs was longer than we thought based on how short the line was, so give yourself plenty of time. Once on the ground in Cambodia, use the Grab app to book a ride from the airport to Siem Reap. A tuk tuk is cheaper but after more than an hour on that hard seat you’ll wish you’d splurged.

Quick and easy, short flight , 30 minutes. Staff was friendly, no food or drinks in this very short flight.

We were not given option for meals since they ran out of the other option but good thing the remaining options tasted great.

Very good flight from Boarding to landing -efficient and comfortable with decent entertainment options

Excelent service and plenty of food and drinks during the flight. Flight crew very attentive to our needs. Leg room between rows are very disappointing.

Construction at PDX resulting in very lung walk from the rental car to the gate. SFO, extremely long walk between terminals to get to connecting Singapore airlines flight. My smart watch recorded a total of 3 miles.

The seat in economy class and legroom in Singapore airline are narrower than Korean airlines! I don’t have that comforting feeling flying with Singapore air as in the past!

Loved the airline with the exception of their carry on limitations. They enforce a strict 7 kilo limit for carry on baggage which is ridiculous. We traveled from SFO to SIN with carry on with no difficulty yet when we checked in Delhi they forced us to check the carry on bags. The weight of our carry on bags were 11 and 12 kilos and while they exceeded the limitations set by Singapore Airlines they were well under weight limitations set by may other carriers. Interestingly my wife and I were each allowed two 22 KG bags to check in addition to the 7 kg carry on for a total weight of 102 KG's. Our total weight with the one bag we planned to check and our two carry ons was 46 kgs.

The staff on Singapore Airlines was incredible. I would like to commend LS Reuben from my SQ37 flight on November 19th, 2024, from LAX to Singapore, for his outstanding service and care. During the flight, one of my earbuds—brand new and valued at nearly $300—fell out and became lodged in the box controlling the in-flight entertainment system. I was understandably upset, but Reuben went above and beyond to assist me in this tough situation. Reuben demonstrated exceptional determination and empathy. Instead of suggesting we wait for an engineer, he immediately took action, spending almost 30 minutes searching for the earbud. He even got down on the floor to ensure it was recovered. His genuine concern and persistence made all the difference and turned a frustrating situation into one where I felt truly valued as a passenger. Reuben is a shining example of the remarkable service that sets Singapore Airlines apart. His dedication and willingness to go the extra mile left a lasting impression, and I want to sincerely thank him for his kindness and professionalism.

The food options and quality could use some more excitement and variety.

I very much liked and appreciated the service on board. The seating arrangement in Business feels uncomfortable. It's not made for tall people, in any case.

Great airline. Excellent service, good food & lots of TV movies/shows to choose from.

The flight has been delayed for nearly an hour, yet neither the captain nor the chief steward made an effort to explain the reason for the delay or offer any apologies to the passengers.

We recently flew with AirAsia and encountered several issues. Our flight was delayed by over an hour, and both boarding and takeoff were postponed without any prior notification. Although we eventually realized there was a delay on our own, the crew did inform us afterward. To make up for lost time, the pilot took off at high speed, resulting in some turbulent moments that were quite scary. Despite these challenges, the cabin crew did an excellent job managing the situation and easing the inconvenience. Overall, while the delays and turbulence made for a stressful experience, I appreciated the crew’s efforts to keep us as comfortable as possible.

I had a wonderful experience with this company. The staff were all very friendly and helpful. Our pilot was skilled and clearly experienced. The value for the price was excellent. I would definitely recommend them.

Very quick turn around, plane was in good condition, alles paletti.

My flight boarding was interrupted as gate staff said I needed visa in advance for Vietnam....

Instead of landing we had to go around and landed in Kuala Lumpur International Airport instead of Subang. Then we had to restart and arrived over 2.5 hrs late

As usual, poor communication on delays. No info, no updates, no apologies.

Boarding was nuts. Gate change. Delayed. No communication from gate staff. They seemed lost. Rest of the flight went well

Premium check in was worth it. Boarding process was a little chaotic. Seats were super cramped and I am less than 80kg and 180cm

It was good. The FACE check in at KLIA2 was not working.
