Scores according to KAYAK customer reviews
Cons: "Flat bed in business class was disappointing. No way anyone taller than 6’ could stretch out. Overall, it was an inferior experience to business class on Cathay Pacific, which sets the standard IMO."
Cons: "Flight was canceled. They moved passengers to the Lufthansa but didn’t tell us even though we checked with the counter every 20 min. Apparently a text went out that we didn’t get"
Pros: "Boarding went smoothly, crew extremely curtious and helpful."

Pros: "Everything food was better selection and allowed me to taste bali food before arriving. The seats were comfortable on the last plane Thank god"
Cons: "Everything. Singapore Airlines had a great reputation. Imagine my disappointment. It was a horrible flight. The crew was nice enough, but inattentive. The food, if such a term may be applied here, was inedible. Just vile. In flight entertainment was a complete joke. Boarding was awful, but it always is. Seats were extremely uncomfortable. This racket is the ultimate way to rip somebody off of $1000. Horrible."
Pros: "Food was good"
Cons: "Boarding was just ok, but departure delayed by half hour. Seats were really poor. Zero comfort.. felt like sitting on a cramped park bench. Entertainment system is ancient. Can't see and can't listen properly. Didn't expect this type of horrible aircraft from Singapore Airlines!"

Cons: "I have to drive from DFW to IAH, I wish Singapore would take over from American and British Air at DFW, honestly Singapore is cheaper, better service, nicer ground and in flight teams. It's worth the extra drive to travel with people that actually care"
Cons: "Our flight to Bali was cancelled due to the volcano eruption. We did not receive any compensation, but Singapore/Silk Airlines told us they were able to get us a flight home to LAX instead, but that it wouldn't be until the next day. We spent money on a hotel and food and waited until the next morning, got to the airport early for check in only to find that Singapore/Silk had in fact, given up our seats that they had promised us. They said that we now would have to wait another day just to get a flight from Singapore to LAX. We asked to speak with a manager, and eventually were able to get two seats due to cancellations. This was intended to be a very special and romantic trip that was essentially ruined. Since no one could have anticipated that the volcano would cause cancellation, we should be refunded for our flights. We are so crushed that we did not get to go to Bali, and now we may NEVER get to go because we are out of money. At the VERY least, the leg of our flights from Singapore to Bali, and Bali to Singapore, should be refunded. We are extremely disappointed."
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: "The staff was very friendly and helpful. I got plenty of meals and they easily accommodated my vegetarian diet!"
Cons: "old plane, boarding ramp smelled musty, food not nice, entertainment system was old not touch screen, male crew not patient with passengers, drinks stingy(split a can of soda with other passengers, and gave you a 1/4 cup). When asked for more OJ with breakfast was told they would come back later(mouth was very dry due to the air). Not impressed as we paid good money for the ticket with the poor service"
Pros: "The ground staff in Sydney!"
Cons: "From the moment we checked in in Singapore there was no service. Having travelled first class and Economy before with Singapore I was very disappointed with Business class. My husband and daughter were in First Class. The service was below average to say the least - more training required from check in to on board - (in Sydney the staff on the ground went above and beyond) In Singapore it was very fake and contained no sincerity. The lounge itself was also ordinary compared to others, no Amenity kits or PJs in business class - even Virgin Australia has that! I was so excited to be travelling Singapore again given past experiences but now Im not sure I will want to fly them again."

Pros: "not too bad"
Cons: "not too bad"
Pros: "Crew on leg from Melbourne to Hong Kong terrible - Hong Kong to Boston good"
Cons: "Put a Priority tag on our luggage; Have the Pasta meal for someone sitting in the second row of Premium Economy and then let me eat the economy meal that you substituted instead of interrupting me four times to give me the Premium Economy meal that you said you didn't have. Use a plane other than th"
Cons: "Flight delayed out of Singapore. Airline should have at least notified earlier so passengers can arrive later to the airport Cabin crew on board rude ‘sorry i’m too busy now’ [just asking for a glass of water] Plane then sitting at HK airport waiting for open gate Arrival timed just perfectly to prevent passengers from catching the last airport express train"

Cons: "I didn't prefer the premium economy section. Uncomfortable. I'd rather pay the fare for a cheaper economy seat, that is equally uncomfortable. It's terrible to start charging people for small, petty things like choosing one's seat."
Pros: "Except for one time service everything else is good"
Cons: "Staff forgot what I have asked for boarding could have been done using zones."
Pros: "Liked: moive selection. Hagendazs ice cream. Flight went smooth."
Cons: "My check in bag was lost. Hope to get it back in the next few days."
Pros: "My mother requires additional assistance for boarding (wheelchair for the ramp, a little extra time). Cathay adjusted our seats so we would be located reasonably near the doors yet close enough to the bathroom for her convenience. The stewards literally took her by the arm to help her to her seat, even taking her bags for her. And they made a point of checking on her several times during the flight. Absolutely amazing!"
Pros: "Comfortable. Good service. No wait for restroom"
Pros: "Little more leg room!"
Pros: "The service from start to finish was superb. The flight to Hong Kong had the on board attendants at full service the whole journey. Blankets and pillows were supplied as standard and plenty of complimentary food. There was a genuine sense that the on board attendants wanted you to be as comfortable as possible."

Cons: "Continues to be incinsistent and spotty service."

Pros: "The airline crew. Very attentive and immaculate"
Pros: "Crew was very nice. On time."
Cons: "No inflight movie available. Long flight. I am a 6 foot American and the seats are just not comfortable if the person in front leans seat back. 15 inched from your face for a 12 hour flight is not fun."
Pros: "Overall was Ok"
Cons: "I did ordered tea cup from flight attendants several Times but they did not remember until I went the kitchen they were eating. I had to ask them again.

Last year we flew business class Cathay pacific from Hong Kong to Melbourne and loved it. This year we decided to fly from Melbourne to Dusseldorf and then from Frankfurt to Melbourne with this airline. Won't be doing that again. Why pay business class fares to be disapointed"

No information to the passengers until last minute. Some passengers does know English."
Cons: "It's not pleasant traveling in economy which is true for all airlines now a days."

Pros: "Crew were super friendly. Food was pretty good for airline food."

Cons: "Again, not being delayed and having to miss my original connecting flight would have been best."
Cons: "I was incorrectly charged credit card fees by BudgetAir as I paid via debit card and they never replied to my emails or answered the phone. This caused stress as my bank account went overdrawn. Cannot recommend BudgetAir at all. Appalling lack of customer service. Avoid like the plague!"

Long queues 3 x 3 seating arrangement is hopeless for 5 hour journey as person at window needs to disturb both middle and aisle seat holder."
Pros: "Can’t find anything good."
Cons: "The airline is protected by the government. Hence there is no motivation for them to improve. This airline is my last choice. My biggest dissatisfaction is the hospitality shown by the crew.. not sincere and in some cases rude... is this the MH - MALAYSIAN Hospitality that they keep advertising? Very disappointing.."

Cons: "Not sure why all Sabah/Sarawak gates are at the farthest..."

Your company then offered me and my friend a hotel stay and transportation to and from the hotel., which was good. I appreciated your company taking care of us. However, it is really bothersome to miss an international connection to go home after a long trip."

I arrived back in Denpasar yesterday and, again, my bags are lost and I again I was told they would be on the next flight. I still do not have my bag. Seems to be a pattern with Malaysian Airways and I will avoid them in the future, Also, I left my Ipad plugged in at the Premier Lounge in Denpasar and realized it as I was boarding the plane. The Malaysian Air boarding staff got on radios and appeared to try to help by telling them to put aside for pick up upon my return. Yesterday, The Premiere lounge said they did not have it despite my name, email and phone number being written on the Ipad. Between Malaysian Air and the Lounge and their lack of concern and professionalism it was not a good trip. As One World Emerald member, I steer a lot of business towards these One World Airlines. I expect better treatment."
Pros: "Liked the USB port for recharging electronic devices"
Cons: "Seats were too close together. Not very comfortable. We were in row in front of emergency exit. Seats didn't recline. We should be alerted when we select these seats that they are uncomfortable."

Pros: "Flight was on time - to the detriment of my late connecting MAS flight from DAR"
Cons: "Food was okay but entertainment was non existent"

Cons: "No alcohol"
Pros: "They left on time"
Cons: "Website is a debacle, asked to preorder meals for business but can't, can't check in on line, business menu was limited, what was on the menu wasn't offered. Seats are uncomfortable, short & narrow. In general for the amount of money paid for business, it's the worst yet"

Pros: "Prompt and great service."
Cons: "Two people on the same PNR, but seated six rows apart. Say what?"
