Pros: "I liked the size of the cups for drinks: smaller than usual."
Cons: "You could train some of your crews to behave more polite to the customers like they do in the Japanese airlines. Male crews tended to be nicer than female crews."
Pros: "Wonderful trip, Super nice Crew , perfect meal , great entertainment system"
Cons: "Can not be topped up"
Cons: "I think the food in our flight was not that good.."
Pros: "I didn't like the trip much. After the trip we found out that our body was bitten by fleas. Our body is now full of rashes, every part of my body is so itchy. We was seated in 61A and 61C, seems like in the previous flight a dog was sitting there or some kind of animal that left fleas in the sit."
Cons: "Please clean better the seats. This is unacceptable, not a good way to start a trip in Japan. We only hope to get better sitting in our last flight with SQ, from Japan to LA."
Cons: "5 crying babies on a red eye. Don’t know if that can be prevented."
Pros: "This was the most fabulous crew I have ever flown with on ANY flight in so many years of my travels! It was un-imaginable as to what they did, they left no stone unturned to make sure we were comfortable, fed us with awesome food every now and then. Were looked after like babies! Thank you SQ!"
Cons: "The A380 was probably SQ's oldest one, which that was a newer plane."
Pros: "Okay in general, nothing impressive"
Cons: "Food certainly need improvement, lacking in attention to ensure food quality. Crews need proper training in customer service."
Pros: "This was the most comfortable business class mid haul flight I've ever taken."
Cons: "Absolutely nothing went wrong."
Pros: "More space then previous flights. Attendants very pleasant and helpful."
Cons: "Ran out of the food choices by the time they reached me. Had to make do with what was left."
Pros: "Satisfied and feel good on Singapore airlines, definitely will consider next trip"

On both legs of my trips (Jhb - Dxb and Dxb - Jhb) the entertainment system did not work.

Pros: "comfort"
Cons: "veg food was mostly repeated and pizza wasn't great"
Cons: "Just because I have bought my ticket on points I was not given a chauffeur driver."
Pros: "The crew was amazing and very friendly. The plane was very comfortable and made the international flight not feel as long"
Cons: "Not much to complain about"
Pros: "The options for drinks for this 13hr flight were great. The food was sufficient. The ride was smooth as usual."
Cons: "I know the crew gets tired too, but the whole crew shouldn't be tired and disappear all at once."
Cons: "Looks like Emirates uses really old planes for this leg. The recliners were not working."
Cons: "Because my husband and I couldn't complete the online check in, we ended up sitting on different ends of the plane."
Pros: "Lucky to have the seat free next to me otherwise not much else good."
Cons: "Was supposed to be a A380 but they changed the flight to 777. I only flew with Emirates to be in the more spacious A380 otherwise I’d have chosen another carrier at better price. I also paid to choose seat which naturally didn’t apply any longer and was put at very back of plane so that money was wasted. They could have at least advised but the attitude was blaze and not willing to even speak to me."
Cons: "The plane is great but the young gentlemen next to me is 300lb+(my best guest He's at least 6'2" possibly in his teen or early 20s) Don't get me wrong but to sit in coach for 14 hours with him in the middle seat is kind of a nightmare. Half of the way we all went to a bathroom and I don't blame him but the bathroom must be to small to clean up himself for I have to sit with feces smell for the rest of the flight. Imagine that. This is my second leg of this long flight from BKK to NYC. The first leg to dubai is horrible enough but this one top that by far!!!!"
Pros: "Check-in , immigration and security experience at Dubai was very efficient via the business class terminal."
Cons: "Old business class arrangement for this route seems very outdated conpared compared to the newer fleet; was not worth the extra upgrade fee."
Pros: "Good service from the crew and good food."
Cons: "Flight was delayed and there are a lot of redundant checks before entering to the gate. No internet service and the flight was very long. (14 hrs)"
Pros: "crew is good and helpful."
Cons: "The food was terrible. Needs to improve the quality of the food."
Pros: "The crew was amazing. Made traveling with infant little less harder."
Cons: "The crew from Doha to Kolkata segment could have been little more helpful, especially when they see someone travelling with small kids"
Pros: "I like that they deliver me safe and sound to Vietnam"
Cons: "I would prefer no interruptions while I am watching my movie"
Pros: "The Crew was amazing. The Seat were the best Selling point fort business class"
Cons: "More space for the arm rest ans legs space"
Pros: "Everything was great ,On time , comfortable seeds, Crew were very nice , boarding was quick Thank you Qatar Airways"
Cons: "Nothing"
Pros: "Our connecting flight was only 1 hour after reaching Doha. They placed a crew member to receive all the passengers that needed to make that connection. Very very useful. Our luggage was made it to the short connection."
Pros: "Our flight attendants were all amazing, but especially Joanna!! She was outstanding and went above and beyond to assist us in every way possible!!"
Cons: "Had an 11hr delay overall, 3.5hrs sitting on the tarmac only to be told to disembark for dinner at the airport. Then told that we won't be getting on until 7am the next day, but only really started boarding at 8:30am. By the time we were told about the reschedule to the next morning, it was too late to get a hotel room (too far away) and was told that I could use a 'Quiet Lounge' at the airport (which wasn't quiet). While waiting to board at 7am the next day, ground staff told us that they had to change the plane so there would be a further delay. On boarding, we discovered that it was the SAME PLANE."
Pros: "Thank you for a very good flight experience both from Philadelphia to Doha and Doha to Johannesburg."
Cons: "The breakfast options could have been better, but I was fed and happy, and the flight attendant was kind enough to bring me green tea when it wasn’t readily available on the cart."
Pros: "Only cleanilyness inside the plane"
Cons: "Customer service at the checkin at the airport and also the service by the flight attendant inside the plane"
Pros: "La atención excelente. La comida muy buena. El abordaje y la entrega de equipajes a tiempo."
Pros: "Helpful crew, great bathrooms"
Cons: "More organized boarding & more AC in the back of the flight"
Cons: "The food was of very poor quality and no alternatives. Went hungry the entire flight."
Pros: "Seats near me were empty"
Cons: "There was no vegetarian food. This is a big thing. The stewardess walked past me although I was waiting to buy from duty-free."
Pros: "Flight was empty so had enough room next to my window seat"
Cons: "The food was an express snack! For a 2.5 hour flight, I think it’s seriously a shame!"
Cons: "I checked in at Hyderabad and the check in staff were more than unprofessional. First they said my carry on bag and laptop bag should be no more than 7 kgs which was wrong. Later when I asked them to show the baggage restrictions, they went back saying it's okay. I had only 1 check in bag and it weight 1 kg more. I thought they would allow it since I had only 1 check in bag but they made me take out that extra kg and check in my carry on as second bag. Finally I asked for an aisle seat and they said the flight was full. But when I boarded the IAD flight I was rather surprised to see quite a few aisle and window seats. So rather than being a great experience, I would say it was a mediocre one because of the Hyderabad staff."
Cons: "The temperature in the plane was too high ie it was too hot and not enough drinks given out"
Cons: "On the boarding time thy check you handcarry wait and on that time if you have extra wait they want to throw I don’t like that because on the counter if they check and tell you have exsis wait you have a option to give your extra stuff to your attendant but they give hard time to pas Sanger’s I really hait that sevice"
Pros: "The crew and well maintained air craft makes my US trip excellent"

Everybody was so nice to treat me good all the workers When I came to Bangladesh there was just a little problem with the luggage but I got my luggage it took like two hours Other than that everything is good

Pros: "I was happy that they didn't lose my luggage like they did on the way to Dhaka."
Cons: "Service is consistently poor and flight attendants don't seem to be trained at the level of Qatar and Emirates."
Pros: "Crew polite"
Cons: "Blankets rationed, crew guessed at food, announcements in any of many languages, blankets shortage. I could go on."
Pros: "I booked on your site and canceled the reservation on the same day and communicated with you by telephone and I was informed that the refund is within seven days and I have not received the amount yet, knowing that on Tuesday 8/1/2019 is the date of the flight that was booked, please return the amount to me as soon as possible"
Pros: "Check in service was good and time was fair Also when interring to the plane, good reception and crew welcoming the passengers"
Cons: "No one helps on weighing the luggage’s specially with families as they have more luggage Also one of the crew was upset and was serving people unhappy"
Pros: "Airport hotel was well organized, efficient with good food"
Cons: "Flight: - very delayed to leave with no updates - host and hostesses were very rude to both ourselves and other passengers when asked questions - ran out of chicken and veg options by the time reached the back of the plane and only had had lamb options left. Abysmal service considering a lot of Asian people don’t even eat lamb! Staff not helpful at all - sarcastically said ‘enjoy your meal’ and walked off - horrified by this remark! - freezing cold flight, when asked for a blanket they said they would give it to children first only and an hour later they still refused to give us one. Also it seemed like the louder you shouted the more likely you were to get what you want, terrible service Overall - not comfortable, small leg room, cold flight, no appropriate food options which can all be forgiven but foremost the staff were rude which is plain unacceptable. Dr P"
Pros: "Very nice staff on flight."
Cons: "Airport was short of sky tunnels so we had to embark via stairs."
Pros: "Served a meal instead of just peanuts. Great entertainment that you can start to watch as soon as you get in your seat."
Cons: "Boarding was a bit behind and they did not post or announce a delay. Passport control at the Airport was way too long and baggage claim never showed where my bag was supposed to drop. I found it eventually. An exit row did not seem to give you any more space like on US carriers."
Pros: "Seats comfortable. Good selection of movies."
Cons: "Late start. People missed their connecting flight. Food was not of my like. Did not supply travelers convenice pouch though toothbrush was available in the toilet."
Pros: "Movies"
Cons: "Food.bording take Long lines. Sale airline tickes with 9 hours transfer and make you buy hotel inside airport for ,125 dollars.this practice is so negative and make kuwait look very bad."
