Cons: "5 crying babies on a red eye. Don’t know if that can be prevented."

Pros: "I do like Singapore airlines and all the rest of the airline stuff apart from the entertainment system was great!!! (Unfortunately since there was no USB or seat power my iPad fairly quickly ran out of juice...)"
Cons: "The entertainment system was soooo old. In our seats it was non-functional. The plane wasn't too full and so I scooted over to the isle seat next to mine but again the resolution on the screen was so bad I couldn't read the intro comments to the movie, etc. They desperately need to update the entertainment system on that plane."

Pros: "Everything about this flight was top notch. The inflight entertainment, touch screen and remote controlled, was so good i was up the entire time watching movies Black Panther, Downsizing, DeathWish, Pacific Rim and listening to the wonderful library of music, i was surprised at the range of music, from uncensored rap to big band."
Cons: "Nothing"

Pros: "Seats in economy were larger than United. Food was good for airplane food, even found a last minute vegetarian meal not ordered ahead. Appreciated a gratis glass of wine. Found a clean pillow and blanket in every seat upon boarding."
Cons: "My screen had to be reset twice as it froze up. The attendants kept taking my water cups despite them not being empty. Boarding was less than organized, could have been more efficient. We made up time, arriving a few minutes early even after departing late."

Pros: "Spacious seats. Lovely food. Wonderful crew. Smooth flight."
Cons: "Interior felt dated given all the awards the SQ has received for its planes and service, but everything was functional. Overlooking the interior, flight was superb. Very happy."

Cons: "Food , both quality and quantity was poor. Entertainment - world movies did not have many choices for such a long flight"

Pros: "Movie selection was great. Food was decent. Comfort was expected"
Cons: "Our seat neighbors were annoying, but nothing the staff can do about that!"

Pros: "I dropped my scarf and only realized after I was seated. People were still boarding and I told a young man attendant and he found it and brought it to me. And he was such a gentleman too! Wish I knew his name but it was Frankfurt to JFK 835am flight on April 3rd. Thank you again!"

Pros: "Service by the crew was great"
Cons: "Food in the economy class was not so great Options provided were not tasty. Each meal tasted same. No kid option available. Tastier options available on other major international flights."

Pros: "The serivce was amazing. Also it was clean and the food was great."

Pros: "The cabin crew was great."
Cons: "1. Flight seats are too congested on flight.. 2. Not too many indian movie choices 3. Some reason, while booking the flight, the KAYAK site had not asked for food choice. And the airline does not carry any extra vegetarian food. This had caused some inconvenience."

Cons: "The seats and there is not much leg room"

Pros: "Crew was good."
Cons: "Despite booking Hindu vegetarian meal, chicken was served. The seats were too uncomfortable and no space at all."

Pros: "I like the services from Singapore Airlines."
Cons: "Your web site tried to charge me $90 for aisle seat, do you agree that this is a big joke or what? I have decided no use your company any more. Not sure why a great airlines like Singapore Airlines would partner with your company???"

Pros: "Great service. Really friendly and polite. Lots of current movies and TV shows to watch and provided earbuds with adaptors. Made the experience a lot more pleasant."
Cons: "The seats can be laid bag pretty far and the people in front of me decided to recline for a majority of the 10 hour flight. I wish the chairs either didn't do this or the flight attendants would have said something. I didn't feel like I had the authority to do anything about it. Also it was so warm! I have no idea if there was a fan."

Pros: "Friendly crew, efficient boarding"
Cons: "Food not good and inefficient service, very old plane and entertainment system doesn't work properly, below expectations for such a good airline"

Pros: "Personal Touch!"
Cons: "No such!"

Pros: "The crew was really great, so friendly and accommodating. I wasn't able to order a vegetarian meal ahead of time, but they still gave me one on board when I asked. There was an amazing selection of movies and they refilled my drinks without even asking. I would recommend this airline to anyone traveling to Asia."

Pros: "Crew were helpful. Food was good, pillows and blankets in every seat was great. Seats a little small."

Pros: "Overall treatment of boarding & crew staff was courteous, friendly & helpful. Movies selections were great but I was too tired to watch."
Cons: "Food can be improved. Couldn't eat pork or shrimps, so wished they served either vegetarian or chicken noodles instead of pork or stuff with shrimps. Fish, chicken, beef, or vegetarian options are better options."

Pros: "The comfort and food plus drinks."
Cons: "Delay in food distribution, over waiting because of many people but only twogroups of serving crew"

Pros: "We did not die in a hellacious ball of flame Aviation incident!"
Cons: "Bulkhead seating (required for bassinet) Row 41, my seat was practically in the aisle. No where to put my feet without getting trodden on by everyone! Broken entertainment screen, would not stay upright, due to several hundred thousand past passengers bashing into it after having first trodden on the unfortunate passengers feet! Crew unresponsive with drink and food requests, I had to ask for services multiple times on several occasions. Pressing my 'attendant button' my light was lit for 10 minutes before a crew member noticed. My first trip on Singapore, my expectations were not met. Shame"

Pros: "Very nice crew."
Cons: "Why are the slippers/socks not distributed before take off or already in the seat pocket? Why is the food order taken after take of and not before? Why does singapore airline have old seats I new planes? What happened to the earlier leader? Friendly staff alone does not make the deal. And given ticket prices SQ is not attractive any more for me."

Pros: "Crew went out of their way to make sure we had everything we needed. Seats seemed roomier in economy than other airlines. Lots on movie choices."
Cons: "I didn't care much for the meals, but my husband loved them."

Pros: "Second bag was four foot bronze statue, no problem or extra cost"

Pros: "The sevice was on point. Flight attendants were beautiful and worked harder than any other airline I have been on. The uniforms were on point too. The television had every new movie you could watch. Food, for an airline, was great. All drink service was included. Best airline I have ever flown!"
Cons: "Wifi cost 12 bucks and hour."

Pros: "The hot towels, the legroom in economy, exceptional service. The helpful crew who don't hesitate to help with luggage. The choice of entertainment. The convenience of a direct SFO to SIN flight with a fast connection to Indian cities."

Pros: "Really recommended . Wait alittle longer but i got a free tour go around Singapore ."

Pros: "Everything"
Cons: "Nothing"

Pros: "Crew was very attentive and professional"
Cons: "Return flight the movies were the same as three weeks earlier."

Pros: "Lots of movie and game options"
Cons: "Staff was slow to tend to my needs (i.e. Water), continually bumped into my shoulder or leg. Would not accommodate moving my seat next to my wife's because a couple wanted to have an entire row to themselves. Very frustrating"

Pros: "Hot/Cold towels, great movie selection, more space, good meals"

Pros: "The flight experience was pretty great overall.."
Cons: "I didn't like that interacting with their websitewas not very iser friendly or reliable. While most domestic airlines allow you to easuly interact with your itinerary I pretty much had to just show up and hope everything worked out. Also no alerts or other functions."
