Pros: "The crew was great although I needed to ask them for my meal cause they passed by me. They thought I had my meal already which I didn’t. I don’t think they did it on purpose so it was just misunderstanding. My flight was on SQ 38 from Singapore to LAX on October 30 2019 Other than that. All is amazing. I will still highly recommend Singapore Airlines to other people."
Cons: "I think I have nothing in mind about improvements because I can see they have been training very well. I would like to say keep up the good work"

Pros: "When the seat folded down (business class) into a bed, it gave almost a twin size bed that was flat."
Cons: "Being in business class, I had expected the food to be better. Also, the red wines offered were only a sub selection of the ones in the menu."

Cons: "This time Singapore Airlines Staff seem to be not so helpful. Previously they were happy to help with smiling face and approachable immediately. This time in spite of asking for help in the cabin no one turned up even after multiple requests. I could only get help when someone one walks next to me."

Pros: "Super friendly crew. Enough food and drink."

Pros: "The crew were excellent"
Cons: "Seats and leg room not as comfortable as older plane. The entertainment system was confusing to use ( again older model) hence not as user friendly."

Pros: "All crew members are very friendly and helpful, good service."
Cons: "All over flight i feel good time, i don't feel boring all friendly staff, good service choice of food i like."

Pros: "Crew were great. Flight was not full."
Cons: "Plane was a bit dated and the entertainment system not as good as the newer plane as choices are lesser."

Pros: "Flight was very pleasant and enjoyable, on time for both departure and arrival."
Cons: "Meals were served rather slow as we were last for row 45 but there was insufficient time for us to finish the meal, collection of trays started in 5 minutes time"

Cons: "Singapore Airlines is so wildly overrated. The service is frequently poor, and the cabin environment dirty and old unless flying on their very latest planes. Even their A380s are now stale and musty. Not nice."

Cons: "The layover in Singapore was a nightmare with insufficient hotel accommodation, nothing but Asian food and overly officious security staff."

Pros: "loved d bnew 787 dreamliner planes. loved d medium haul biz class seats."
Cons: "everything is excellent frm d check in to d lounge to the plane , crew service , arrivals and lastly baggage handling ."

Pros: "Nothing beats Singapore SQ!"

Pros: "The cabin crew were fantastic. Food was abundant. Most boarding systems worked well. Choosing seats was confusing on website so we were allocated seating. The newer planes had a fantastic touch screen entertainment system. The seats on the newer planes were much more comfortable and roomy"
Cons: "The small seats are squishy on the older planes. The entertainment system on the older planes were dated and difficult to use. I felt sick after the flight to UK but felt fine coming home after one long flight on a newer plane."

Pros: "Excellent crew, service and food"

Pros: "Crew was very friendly and responsive to my needs. They met it with a smile."

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: "Entertainment"
Cons: "Way too cold"

Pros: "Very comfortable"
Cons: "I don’t see anything I didn’t like"

Pros: "Again friendly and efficient staff and a smooth flight. Best features of Singapore Airlines."
Cons: "The business class seats were smaller than I thought and not so comfortable as the 777. The seats are hard and ungiving and when you sleep on them you really feel it. Plus the flatbed lay out meant you were basically lying in a question mark position, not so goof for tall people like my husband. The food was good but uninteresting and I think for an overnight flight there should be more smaller,lighter, non spicy options offered rather that full dinners."

Cons: "Please don’t use just fly.com ever. They cancelled my tkt and never accommodated a new one"

Pros: "Spacious and comfortable bed."
Cons: "The food wasn't that great. Average at best."

Cons: "The plane was freezing - absolutely freezing. Too cold. There were not enough fluids given out. Given we could not even take water brought in the airport into the plane there needed to be regular distributions of fluids on the flight as there was on the flight from London toy Singapore. It is a long flight and being dehydrated on a plane is not a good thing."

Pros: "Nothing"
Cons: "I took the 777 on my flight to Perth and the seats are so so different from the ones on A330. Don't bother with Business class if you are flying the A330. It's not worth the money."

Pros: "Entertainment excellent, cabin crew superb"

Pros: "Great service and comfort."
Cons: "Food was bland and breakfast availability was a joke. On any flight, passengers do not want spicy or evening meals, and having a limited amount number of breakfasts available was not amusing. The crew had done 5 rows and we were 6 row from kitchen and they had run out ."

Pros: "Comfortable, full service through the night.."

Pros: "I liked the space I had to stretch out, 3 seats to myself in economy enabled me to get some solid sleep between meals. The crew werebalways very polite and friendly."

Cons: "Boarding at Singapore airport was shocking, as we had to wait 6 hours for our flight. Rating low to the crew mainly because of the ground staff as they were not very communicative to begin with about the explanation for our delay. Only when the passengers got a bit more vocal about wanting explanations, they started giving us a bit more information. All estimated times given for boarding the flight were incorrect by a big margin! Seemed more like they were giving shorter wait time for boarding just to please the passengers, where as they were well aware of how long the wait would be."

Pros: "Modern aircraft , nice crew"

Pros: "The service from the ground crew and cabin crew are very professional. Friendly and very helpful."

Pros: "Friendliness and efficiency of crew. Comfortable seats and in-flight entertainment."
Cons: "Not much. This airline is up there with the best."

Pros: "Food was delicious!"

Pros: "Boarding was good"
Cons: "Old plane, bad food selection and they run out of omelette in the morning - only seafood as option. Not rude crew but wouldn't call them friendly or welcoming."

Pros: "The staff are so friendly and helpful. Highly recommend travelling with the airline. The A380 is a great way to travel with more space in economy. I booked seats on the upper deck where there is a smaller economy cabin. Makes you feel a bit more civilised up the top!"
Cons: "Economy class isn't great for a long haul flight but the staff make it much more bearable."

Pros: "The hot towels. The meals were good. The entertainment screen was great, and a great selection of movies and TV."
Cons: "Don't change anything!"

Cons: "Food"

Pros: "Staff was the best, always smiling and going beyond expectations to assure you enjoy your flight and I certainly did. Take off was a breeze. Landing a little bumpy but nothing to cry about. I will fly Singapore whenever possible from now on."
Cons: "There was nothing that I didn't like."

Pros: "Neat & clean flight.good cabin crew members.good service."
Cons: "Food served was not so good. Toilets are very small compared to other flights..speacially SFA - Singapore flight."

Pros: "Main Entree hot"
Cons: "Cold bread; dessert similar sweetened gak"

Pros: "service, good TV quality and good movie selection"
Cons: "sound quality with headphones was horrible"

Pros: "The staff were very friendly and it was a smooth flight with a great choice of entertainment."
Cons: "However I don't eat pork & they ran out on chicken dishes so I missed out on a meal."

Pros: "I love flying by singapore airlines! Firstly because its direct flight from home plus service on sq is always impeccable. Plus i can easily order a singapore sling and a campari spritz, which is so nice while watching a movie :)"
Cons: "I didnt really like the food this time and entertainment on the way back was so sad! No new movies unlike on the way there :( dont really like being woken up for meals though, would be nice if they left a note to get a meal from them once ive gotten up. Coz i was trying to sleep so i dont get jetlagged back in sg. Which i did unfortunately :( not jetlag when i arrived in rome though :)"

Pros: "Excellent crew service and entertainment."

Pros: "Always great and efficient service. Comfortable despite the limitations of the plane itself (don't particularly like Airbus planes)."
Cons: "Wish the food could have been better and the choice for dessert wider."

Pros: "Everything on time."
Cons: "Nothing really bad one food on return flight not great but ok."

Pros: "Spacious, comfortable seat"

Pros: "Great customer service, food was fine, seats were comfy in economy too. Definitely would fly again and recommend to everyone!"

Pros: "The graciousness of sraff, entertainment options, cleanliness of the aircraft. Always willing to make adjustments to accommodate."
Cons: "Its unfortunate that your staff sometimes do not get treated with the respect they deserve from a guest"

Pros: "The food, the seating, the upgrade, the very polite and attentive staff. I thanked them, and for that, they gave me a hand written note and a set of cards. So sweet. Totally worth it to fly Singapore."
Cons: "I didn't like how Vayasan and Singapore airlines telephone check in both claimed they could not upgrade. It was part of the policy/seating I bought. They were wrong, the airlines at San Francisco airport did it without blinking, after checking my visa status."
