The Singapore Changi airport if huge. After getting of the aircraft, the walk to immigration control was long. Once you get to the control area, the process was quick and easy.

Airline reviews

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

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

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

Wish the underseat compartment don’t have a restriction, can fit a personal item such as backpack fully like most Boeing

Crew and service excellent. 2 hour delay for takeoff. SQ app showed flight on time.

Everything was great keep up the good work 😁, can't ask for more.

Flight from SFO did not include entertainment as it was not working the entire duration of the flight. Was informed that there would be a $350 voucher for the inconvenience. Uncertain how the voucher will be provided.

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

On time boarding I would like to see ground hostess to help transit customers to direct them to the right terminal and boarding gate. Last night, all the transit customers on SQ484 arriving Singapore had to merry go round to look for terminal and boarding gate to board SQ128 transit to KL Malaysia. We went to Terminal 3 taking the Skytrain to T3 and back to T3 to get out to look for different Skytrain to T2. On arrival t2, we had to go round to ask which boarding gate to KL. We only had 5 minutes to make to the boarding time at 6:55pm but we already spent more than 30 minutes running around to find the boarding gate. We were late at the boarding gate.

My daughter and I had a pleasant trip to Singapore. Reliable and on time.

The pilot was late so we didn’t take off til almost 2 hours late.

Flight was late, the only reason I almost missed my flight was that my connection was also late.

Baggage claim signs were not updated with my flight information, so I had to guess. The app wasn't updated either.

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

The seats were very uncomfortable. I paid for the front economy. i swear they added a row of seats in there. It was so tight, that I could measure the distance between my seat and the one in front from my elbow to the tips of my fingers plus six inches. The seat cushion was completely worn out. The dinner was very good. Thank you for having a vegetarian option as a standard. But breakfast was nothing but sugar. that's not food. The crew was crabby and rude, especially in regards to coming to the back gallery. And the entertainment choice: why would you put violent movies on the choice? the Godfather? Some movies with black women being beaten over the head with clubs? What the heck? You know that when there is a movie on a plane, everyone gets to watch it. Why choose the most violent titles possible? The total number of movies were very limited, and the television, even more so. No games were available on the set. The wellness section was nice, thank you. I appreciated a galley in the middle where I could stand. The seats were unbearable.

UA594 was delayed multiple times. I ended up getting picked up so I can make it in time for work 6AM on Monday, 7/6/2026

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

Food is very bad and entertint not too many options ... flight attendet service is not good

For a 17 hour flight, they kept us well feed. The music selection could be better curated. The entertainment selection was about what is expected. The crew was fantastic.

I forgot to pre order gluten free on a 16 hour flight and I am pretty sure the crew raided their own lunches and first class to keep me fed.
