Airline reviews

Pros: "Again seats space could be better. Crews were very attentive."
Cons: "Other passengers reclining their seats could be a nuisance..."

Pros: "The boarding process was easy and straightforward, the seats were comfortable and had individual entertainment screens, the crew was very polite and helpful. For meals, everyone was given a printed menu at the start of the flight so that meal options could be easily made."
Cons: "My only complaint is that I would have liked to see more frequent offers for water refills during the flight, since water cups are so small and staying well hydrated on flights is difficult but essential."

Pros: "Plane was super clean and comfortable. A long flight but we'll cared for by host."

Pros: "Very comfortable; excellent service"
Cons: "Food"

Pros: "Amazing crew. On-stop flight. All premium economy for reasonable price."
Cons: "Silk air"

Pros: "Crew is attentive to our needs"
Cons: "NA"

Cons: "Nothing"

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: "Crew , announcements were restful , not loud and blasting like some airlines"
Cons: "Nothing Singapore Airline is Super Lufthansa food lousy , late leaving Kuala Lumpur, missed our connection assigned to a later flight, running to catch rescheduled time and changed gate."

Pros: "Service was excellent!"

Pros: "okayish"
Cons: "Delay could be complimented by faster speed"

Pros: "The crew was lackluster; unusual for Singapore Airlines. Tall individuals will not like the business class seats."

Cons: "Seat space could be wider for working"

Pros: "The crew werr very helpful and patient and so many languages they knew. Impressive they need a raise"
Cons: "The seats were uncomfortable I slept 30 min at a time on my 14hr flight. The food is nice but a bit bland the first time its amazing but after more than 2 planes mix it up plz"

Cons: "without any possibility to call back. or to call again while being late, when arrived with plenty of time before departure. nobody was on the gate. when tryed to do all myself whithin minutes tsa didnt bother to speedup process and it took forever. i missed my flight literally in seconds."

Pros: "Service was excellent, always with a smile."

Pros: "The customer service at the Check-in, the flight attendants, the movies and the meals. More than my expectations! Will definitely use Singapore Air in the future in my travelings! Will recommend it to my circle of friends and relatives! Thank you very much. You are the best airline I've used since 1976!"
Cons: "Nothing."

Pros: "The flight attendants are very attractive and attentive. They do make an effort to make one’s trip pleasurable."
Cons: "Need to update the planes.."

Pros: "Basics are covered. TV screen is big but otherwise nothing special."
Cons: "It is so annoying they want you to pay an extra $20 to pre book any seat. If you need the extra $20 that much, charge me in the original fare! Don't nickel and dime me. At check in they couldn't even get my child seated beside me although a change was made last minute at the gate. Every other airline I've flown recently was better. Sri Lankan and Emirates FAR better service."

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: "Loved the food/Movies/seats."
Cons: "No air vents and the cabin was very very stuffy and warm for many people. I’ve never heard one child cry for 7+ hours before until this flight. But everything else was decent to say the very least:)"

Pros: "Ok"
Cons: "Delayed"

Cons: "The seat's recline button was broken which meant having to sit for 12+ hours upright. Upon hearing that the seat was broken, the airline crew offered my mother a check for 100 SGD (14% of the ticket value) to be used on Singapore airlines (for the discomfort caused for over 50% of the flight time). They changed her seat from Seoul to Singapore. When I wrote to them about it, they came back saying they had offered her a seat change from LA to Singapore, and she had declined, which is absolutely false. When I called that out, they said, maybe they did not offer aisle seats (note that the broken seat was not aisle). So it just shows that they don't want to accept that they messed up. They even told me that despite their best efforts in pre-flight checks, certain defects only surface when the flight is in progress. Will never ever travel on this airline again."

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: "Great entertainment system for a short haul fl flight"
Cons: "Terrible food"

Pros: "I haven’t flown Emirates, but SQ beats the many others I have flown by a significant margin—especially the Chinese airlines, but also all major US airlines, JAL, Korean, et al."

Pros: "great crew service. my first time flying with singapore airlines. they delivered!"

Pros: "The seats seem to have more leg room, food was actually good, and the staff was delightful."
Cons: "It was a 17 hour flight, but they made it bearable."

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

Cons: "The cabin was quite warm"

Pros: "friendly staff top Service top Inflight"
Cons: "new aircraft, 2 x usb charging ports, 50+ movies, very quiet aircraft."

Pros: "Excellent service & comfort"

Cons: "I purchased this ticket without realizing that the law stipulated 6-month validity remaining on one's US passport to enter singapore. The Singapore Airways website does not state this anywhere, and it was not until I arrived at the airport that I was informed that I wouldn't be able to check in, but nor could I refund or transfer the ticket. The booker should be obliged, when one enters the passport information upon purchasing the ticket, to make note if the passport expiration time is not valid for the flight. Spent $600+ on the flight, and the customer service person I spoke to from the airport was very abrasive and not interested in helping me figure out an alternative."

Pros: "Service was great."
Cons: "Bit on the cold side."

Pros: "Everything great personnel"

Pros: "Red wine was good"
Cons: "The seats in economy are now Way TOO SMALL! You better start calling Economy - "Stearage"! Food was not as good as on past flights with SA. Movie selection not as good as past SA flights. Earphones supplied are horrible!!!"

Pros: "The food was excellent for Vegan meals. The staff was friendly and attentive. The ability to see the flight path, air speed and such is very nice."
Cons: "The entertainment was not the kind of shows I like. Never mind, I see the flight path and orher flight particulars."

Pros: "The friendliness of the staff, the food and overall the experience."
Cons: "That our bags weren't check in all the way to SEA"

Pros: "Everything"
Cons: "Nothing"

Pros: "Staff on board were lovely."
Cons: "I asked to be placed in a seat as close to the front as possible as I suffer from motion sickness in the back of the plane. I was placed in the back row all the way to my destination and all the way home. I vomited 8 times and felt very sick. I did notice that there were many seats available in the front of the plane but they are never given out as women with babies and children always get them and then single travellers like myself are made sit in the back. I travel a lot, I usually fly Qantas and they are very good at providing seats closer to the front. I will be reluctant to fly Singapore Airlines again due to the fact that they were not accommodating at all."

Pros: "Courteous, Professional Crew. Amazing Service."

Pros: "Excellent service, food, in-flight entertainment (what choices!!), and the plane was very up to date as well. Made for a very very pleasant flight experience. Especially for how long the flight was (18 hours or so)"
Cons: "The get out and get back in halt at Hong Kong. Practically the entire flight had to do this, quite wasteful. Bad customer experience. Find a better way please! If Hong Kong makes you do that switch over to another airport, better yet make no halt. I have flown direct from SF to Singapore before so not sure why this halt."

Pros: "It was a standard flight"

Even if you have diamond one world status (the highest) unless u fly business class there is no chance in getting more onboard for your carryon. Works best airline my a**!"

Center seats are really tight, elbows are in the way of all passengers and if you are average height you have to turn your legs at angle to sit which infringes on other passengers' spaces. very uncomfortable. Aisle next to me is so small."

And I booked the flight with this company cos I thought they have a great service, but not what I expected, they didn't provide a wheel chair and she has to drag all the bag with one working arm , so I m not pretty satisfied with the trip at all and I won't fly with th company any more"

Pros: "The staff were welcoming and friendly. Their customer care is second to none. The food is excellent and i ate throughout my flight."
Cons: "The comfort was a bit below my expectations. Sitting on the seats along the isle was uncomfortable as they are closely placed. There is no enough room to move and to lean sideways when one wants to sleep. My tv was not working. The touch screen was not responding. However the friendly flight attendants shifted me to a vacant seat where the tv was working. The movie selection was limited. There were no documentaries about wildlife. Sport was also missing. We also need some news channels like Aljazeera, CNN & BBC so that we keep updated on issues happening throughout the world. This is very important especially to people like me who traveled long distances from South Africa to Los Angeles USA."
