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.

Return Premium Economy section to the smaller section with comfortable seats. Add internet, upgrade the meals, and upgrade/update the Movies and Music onboard.

We paid extra to check our bags ($90*2=$180) but our luggage remained in Frankfurt. VERY DISAPPOINTED as we were promised that our luggage would go to our destination. We had to pay 90€ to take a taxi back to the airport in Split the next day to get our bags so we would not miss our next step on our trip. We think we should be reimbursed for our checked bags. How can we coordinate this?

Boarding, time to take off, in flight offerings, and staff were all great. I recommend using UA for this short flight.

This was an auto-rebook due to being delayed from an earlier UA connecting flight. The boarding was fine, but they sat me in a middle seat when my original booking was a window seat. Overall, the flight was fine as it still got me to my final destination.

The flight out of Fresno boarded 1.5 hour past scheduled and made me miss my connecting flight from SFO to SEA.

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

UA28 was good service and meals. UA is upgraded, I would like to book for next flight by UA Thanks Liao

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.
