Staying at Crowne Plaza at the airport was really great! It’s easy to spend time in the city and worthwhile even for a 24 hour layover. The airport is of course fabulous and probably enough for entertainment for under 6 hours layovers

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

Crew and service was excellent, but passengers should be offered a welcome drink before take off which did not happen. Food was very good. Unfortunately the lie-flat bed in business class was one of the most uncomfortable I have experienced. The configuration forces you to sleep with your legs at an angle instead of in a straight line, plus there is very little padding on the bed so it wasn't possible to sleep for more than 2-3 hours on an 18 hour flight. For what the airlines charges for a business class ticket their hard product leaves a lot to be desired.

It was very good experience on board to Sydney with SQ.

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.

Overall, very good. The food was better than expected with the exception of the pork and potatoes dinner at the end of the flight. My family all selected that dish and did not set it. I tried a bite also and it was honestly terrible. Also, it would be helpful to know when the snacks in the back of the plane are available.

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.

Timing very good from sfo to Singapore and service was awesome and economy class seats are great overall very good experience thanks

The seats were more narrow than at other lines. Food was mediocre (economy class)

Food option Hindu veg to Hindu non veg request was unheard

AWFUL. I have had the experience of traveling with many airlines across the world, and hands down United Airlines is the worst. Not one flight was on time, and I don’t think I met one crew member or staff member who wasn’t rude.

For an 8.5 hour flight the service on board lacked a bit. Service start was slow, the food was worse than usual and they skipped the snack they were supposed to deliver before landing.

Wish movie and music choices changed more often. Mostly same from a month or two ago when I last flew.

It was good. Just that the seats could not be reclined. The people behind were not ready to let the chairs be reclined

Checkin was painful and slow! Lady didn’t seem to know what was going on and couldn’t explain the delay. Seemed ahe couldnt see the computer scree and we couldn’t hear her talk through her mask.

Plane left & arrived early- 5 Crew great. Wi fi - paid for 2, only 1 worked - so so. Waste of $. Coolie was good

There was no USB plug in my section of the plane. So I could not charge my phone. Also, there was no screen to watch movie or anything like that. Wish I had known that in advance, I would’ve brought my iPad.

Made all groups except 2 check despite ample bin space. Inflight WiFi and entertainment didn’t work most of the time.

Not enough room between rows and food was gross. $160 baggage charge?! Never again.

Waited for our plane from HNL so we didn't miss connection. AMAZING Service for that, then really clean plane. Nice airline attendants.
