Airline reviews

Cons: "Left 45 minutes late though we boarded on time. Pretty bad for a 50 minute in the middle of the morning."

Pros: "Crew very attentive but not intrusive. Food very good."
Cons: "I did not find much to watch on entertainment system. Have to get crew to assemble flat bed, a bit of a nuisance. Also to turn it back into a chair."

Cons: "Having boarded at SYD, during the Canberra stop, we were all required to disembarked. It was a loaded flight so the process was slow"

Cons: "Raise the cabin temperature"

Cons: "Missed my connection so lost bags . Took 2 days for them to get to me."

Pros: "crew were very friendly and helpful. flight was one of the best i’ve had"
Cons: "boarding at sydney was very confusing"

Pros: "Although business was full, it was quiet. Cabin chief was very helpfull and professional."
Cons: "food choices are not bad. TV screens are super bad. Resoulition is almost from 90's era first flat screens! One stewardess had friends in business. a couple sitting one after another in window seats. She spent most of her time chatting with them, taking photos while we were trying to sleep."

Pros: "Crew were very good. Cabin was also much better than Qantas premium economy cabin."
Cons: "Had premium economy seat. Not the most comfortable on the tailbone for some reason."

Pros: "The crew was great as usual. The food was good"
Cons: "Better seats - really uncomfortable with a packed plane and wailing infants even when seated quite a few rows away."

Pros: "Wow they did not disappoint flight attendants Overdid themselves with amazing service planes are super clean and entertainment systems are state of the art great job Singapore Airlines can’t wait to fly with you again you definitely earned your #1 ranking"

Pros: "Seating was spacious, crew was attentive. Boarding was efficient."
Cons: "The food choice was not pleasing to me."

Pros: "Staff are great and on board service was good. Boarding is always well organised from Changi however it was a full flight and as always half the passengers exceeded their carry on allowance. Rather than addressing this bags were flung everywhere no nowhere within your actual reach during the flight. Very annoying when you are a passenger who does the right thing."
Cons: "See above. No in flight entertainment makes you feel like you're flying with the low cost carrier rather than a full service airline."

Pros: "Movies selection was great."
Cons: "Food and comfort were not as great as I thought they would be. Not bad, but not worthy of the brand Singapore airlines."

Pros: "all of SQ"
Cons: "nothing"

Pros: "Friendly and helpful crew. Efficient service and good boarding. Seemingly wider seats than the newer A350s."
Cons: "Positively ancient entertainment system with poor selection and bad visual quality. Ads pop up every time you go into another menu. If you're flying SIN->BNE I'd avoid the 7.20am departure, you'll get the old 777-200s rather than the A350s they run on other departures."

Pros: "Punctual flight with friendly crew."

Pros: "The crew and the little things like blanket, pillow, hot towels etc that is just standard. The food was great except the bread rolls Entertainment system was fantastic"
Cons: "They seemed to miss a whole section with immigration cards which delayed my party of travellers when we landed. The recline of the seat is huge, great for those wo recline, not so great for the person behind them"

Pros: "Singapore airline crew is always top notch in terms of service and attentiveness. It's a direct flight from Singapore to Canberra! Beats the layover in Sydney or Melbourne."
Cons: "Business class seats were uncomfortable compared to other business class. They're not lay flat seats, and I can't get the seat even close to flat because my feet jam in to the bottom of the seat in front of me. The food wasn't great, some of the meal which was supposed to be served hot was still cold."

Cons: "Some staff not courteous which surprised me"

Cons: "Service"

Pros: "It was good"

Cons: "I was travelling with a toddler and they did not have a toy or activity to give her on a 15 hour flight. We were told to keep our seats upright during meal times and to keeo our window shutters down during other times. This made sense. But there were passengers right in front of us who had their seats reclined during meal time and the crew did not tell them anything."

Apparently everyone on the plane had to use the bathroom at least 3 times during the flight--plus the drink cart went by another 10 times."

Pros: "The stroll waffle"

Cons: "Price"

Cons: "The United mobile app as well as my emails stated that the gate was B3. Upon arriving at gate B3 and attempting to board, I was alerted that I was at the incorrect gate. The gate was switched to C11. However, my app did not alert me nore did it reflect the gate change. I didn't receive a text or email update. I had to run to the different concourse nearly missing the fling."

Pros: "Excellent cabin service. Arrive destination on time."

Pros: "They were prompt and polite"

Pros: "Didn't fly to San Diego-got rerouted to LAX instead. Had I continued to San Diego I would have landed almost 6 hours later than my previous arrival time all because of delays at the gate in Harriaburg. An original 30 minute delay from weather is understandable, and by the time the aircraft arrives you'd think they'd be ready to deplane and get it rolling quickly. Nope, not all. I think it was amateur day in Harriaburg because it was like no one knew what to do and nobody could make their minds up."
Cons: "See above. This is why I drive everywhere."

Pros: "Staff and comfort good."
Cons: "Samething no help to my flights or cabin."

Cons: "After sleeping in the airport all night, I was put in the seat next to the restroom which smelled really bad"

Cons: "very late."

Pros: "Pilot was the best. Best landing ever."
Cons: "Deboarding because they didn't have a plane with the right spoilers so we could land on San Diego's short runway. The pilot had mentioned it and they still boarded us and then had to have over 299 people get off and move to another concourse. United should listen to their pilots and think safety for their passengers."

Pros: "On board device entertainment."
Cons: "Lack of seat space in the back, have to pay for wifi."

Cons: "Round my credit card"
