Airline reviews

Pros: "Crew very polite and friendly"
Cons: "Crew forgot to bring me things twice so I had to ask another crew member on both occasions."

Pros: "I loved that the airline offered several meals, snack options and drinks. The attendants were amazing and would highly recommend Singapore airlines to anyone flying internationally"
Cons: "The limited arm room/personal space. Not much leg room in economy for a 10 hour flight. Would be nice if airlines would decrease the number of seats and give a little more room so people aren’t hitting each other in the head with their arms"

Pros: "Crew were amazing and great entertainment"
Cons: "Boarding could be better"

Pros: "They were very generous with food and drinks. It was a pleasant flight."
Cons: "Our seats were uncomfortable. We did not like sitting on the front row three deep. We would have preferred the extra legroom seats we had on the 1st flight"

Pros: "Cabin crew was amazing!"
Cons: "Food was mediocre and we've had better on Singapore Airlines before."

Pros: "Cabin crew knew how to work."
Cons: "So surprisingly, the cabin was dirty and the seat comfort was below expectation."

Pros: "The cabin crew and the pilots. The flight went smoothly."
Cons: "Singapore Airlines should inform clearly of the mileage policy and the lounge access while using a code-share flight. I thought I booked as a code-shared Singapore Airline flight, but I got rejected from the lounge access."

Pros: "Dim sum between Hong Kong & Singapore."

Pros: "Staff very attentive not disturbed after meal The smiles and demeanor of the staff"
Cons: "The flat bed is not comfotable needed help from attendanr all the time felt like i was constricted"

Cons: "I liked everything"

Pros: "Seating was spacious, crew was attentive. Boarding was efficient."
Cons: "The food choice was not pleasing to me."

Pros: "The service was excellent start to finish. I found the movie selection to be excellent on the plane and the food was tasty and above average for airline food, and the seats were comfortable."

Pros: "The Staff was very friendly."

Pros: "Entertainment ok but not newest, boarding smooth, food ok"
Cons: "Long waiting time for baggage, food not exceptional"

Pros: "Boarding was good and the flight time was shorter than expected."
Cons: "My son did not like any of the meal selections between beef and fish. We asked for a ramen noodle cup instead that the flight crew denied they had, only after seeing them offer it to another family just seconds before. I was very disappointed!! I believe the flight attendant knew of my concerns because she started asking me if the service was ok. If your doing a good job, then you won’t have to ask."

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

Pros: "We love Singapore Airlines, seriously it's not hard, you just have staff that care, clean comfortable air craft, good inflight entertainment. Are you listening American and British Airways?"
Cons: "Please move this service to DFW and displace the rubbish transatlantic service that is there"

Pros: "The flight attendants were amazing."

Pros: "Amazing service!"
Cons: "N/a"

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

Pros: "This time I made the mistake of flying with my kids (4 and 6). The flight or them was last minute (booked less than 8 hours before take off) so there were no pre-planned kids meals etc. The in cabin team were awesome! They made sure they go a choice of meals, that they had things to do, that they were enjoying the flights. This on top of the usual awesome that they have."
Cons: "It's still in Huston. Flying economy isn't the same as flying business but my bank account says I need the cheaper option. Can we please move this flight to DFW instead? :-)"

Pros: "More movies and TV than you can watch, incredible cabin team, low cost, I mean, what's not to like. American, are you listening?!?"
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"

Pros: "Great crew, good food (best I've had on an airplane), plenty of drinks, and a good entertainment system."
Cons: "Nothing bad to say about this flight. Great airline."

Pros: "Foot rest, large movie screen, good food"
Cons: "They ran out of diet drinks."

Cons: "Flight delayed twice without informing us the reason, and after boarding, we waited for v long to take off also"

Pros: "The presence and attitude of the flight attendants were highly pleasant and accommodating. The entire flight was very comfortable and made the 9 hour journey from Manchester to Houston Texas fast and enjoyable. The flight attendants always had a wonderful smile which felt genuine many a time and always made an effort to speak at the level of the passenger. When I had trouble connecting to the Wifi, one attendant even knelt down and connected my phone manually as I was not tech savvy in this regard. The food was of much higher quality as well compared to other airlines I traveled with on this trip."
Cons: "Really the only issue was there was a 2 hour delay on departure, however this was due to issues out of control of the airline and I did not mind as the airline's ambience and my experience with it overshadowed any delays."

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

Pros: "Crew was great. Food not bad for airline food . It was clean."

Pros: "Awesome comfort, infotainment, service and food. Was amazed at the value for an economy flight - much better than BA & United in every way."

Cons: "Food was very poor."

Pros: "Delayed flight from Shanghai due to air traffic issues, so I had a 10 minute window to make my connection in Singapore. Ground staff was waiting for me with a small car after I disembarked to drive me to the gate. And I somehow made my connection. Excellent service. Obviously my checked bag didn't make it, but I was told in advance and was kept updated before boarding and immediate after I disembarked at my final destination. When I went to the baggage service counter, they were already ready for me, had filled out my paperwork, and just needed an address to confirm the delivery of my suitcase. I'm super impressed to this attention to detail."

Pros: "Loved the crew. Really helpful."
Cons: "1) while boarding you should keep families with kids (at least till 6yrs of age or with disabilities) prior to other people... 2) food was ok ok"

Pros: "Ease of checking. Empty seat between us"
Cons: "Can't upgrade with krisflyer miles"

Cons: "Too hot in plane Food really late, 1h after special meals Entertainment system archaic, age of plane All isles seats gone as soon as checkin open"

Pros: "again, the crew anticipated our needs"

Pros: "Everything is suport wonderful"
Cons: "Price. it's better"

Pros: "The crew and inflight food and entertainment was good. The person on the transfer desk was very helpful."
Cons: "We were unable to use the website to check-in online, which meant we had to fly to Manchester to check-in. Which is very poor given modern technology. (We were able to check in on line for the flight from Houston)"

Pros: "the service on the flight was the best I can ever recall having."

Pros: "Had a row to myself to stretch out. Not crowded, no wait for bathrooms. I like the warm washcloths after we settled in and before meals. Plenty of blankets and pillows."
Cons: "Food was ok, not super high quality."

Pros: "Exceptional service!"
Cons: "There should always be a vegetarian option on the set menu. I didn't realise I would need to pre order my meal for this."

Pros: "Extremely polite flight crew"
Cons: "-The food was pretty bad -The movie sound quality was bad, and the subtitles didn't work -Not much leg room"

Pros: "Comfortable seats."
Cons: "We were supposed to fly back to Los Angeles from Tokyo on Wednesday, August 24th. We got to Tokyo Narita a little later than planned due to the Narita Express train being delayed. I had received emails that our flight had changed gates, and was then delayed, but when my sister and I went to check into our flight, we were told we were unable to board because it was too late. I thought it was absurd because the flight had not even started boarding, and I had gotten an email saying it was delayed. We tried to reason with them, but they would not let us on the flight. It was imperative that we got back to Los Angeles on Wednesday, but all our plans were ruined due to them bumping us off the flight. My sister had a connecting flight to Boston, which she then had to reschedule and was charged for. We were stuck another night in Tokyo, where we had to spend money on a hotel. The Singapore Airlines attendants eventually informed us that we could get on a flight the next day. This delayed us by 24 hours, which was highly inconvenient. It was also especially unnecessary since due to the flight being delayed, we would have absolutely been able to make it. I do not appreciate being bumped off of a flight due to airlines wanting to make more money, especially being stuck overseas. Its not like it was a domestic flight where we could just hop on another one in the next few hours, this totally derailed all of our plans. I do not appreciate the inflexibility of the Singapore Airlines agents, and this is not an experience that makes me want to recommend flying with Singapore Airlines. I appreciate that they did not charge us, however it was a major inconvenience that could have simply been avoided by better customer service and understanding."

Pros: "Singapore is #1 in my books. So glad I could get on their airline. The flight was super. The economy cabin was really nice and comfortable. I especially liked all the adapter plug outlets to power my equipment. I just can’t say enough good things about the cabin crew. The Stewardess were very attractive in their uniforms and make-up, not like the old maids United and American has. The cabin crew were extremely helpful and nice. The service was impeccable. The meals were actually pretty good. Course all the alcoholic drinks available was nice. A person could get wiped out pretty easy if not drink responsibly. But not a good idea to drink much cause of the aftereffects after the flight."
Cons: "The headset ear plugs left a lot to be desired. I need to bring my own good set to enjoy the vast selection of music and shows available. My number 1 complaint was the outside row seat armrests would not move up. This makes getting out of the seat into the isle much more difficult than it has to be. Why does it have to be stationary?"

Pros: "Singapore airlines was awesome. I really enjoyed the hospitality of the cabin crew. They were very helpful and very eager to fill my needs. I will fly Singapore Airlines again without hesitation."
Cons: "Be more descriptive with which connecting flights we need to go on. We were not aware we we're supposed to get on Silk Air as one of our connecting flights, but we did eventually figure it out. It would really help to let us know your subsidiary companies."

Pros: "Service and Operation"
Cons: "The plane ... its old, in need of a new interior as things are falling off and dirty ... Flew business class and although the service makes up for the old aircraft, i think SQ can do so much better !!!"

Pros: "Service and Operation"
Cons: "The plane ... its old, in need of a new interior as things are falling off and dirty ... Flew business class and although the service makes up for the old aircraft, i think SQ can do so much better !!!"

Pros: "Excellent service by SingaporeAirlines. Nothing more to ask for... everything was very good."
Cons: "the food I pre-ordered wasn't available in one of the meals (premium economy class)"

Pros: "Crew was great. Boarding was efficient and timely."
Cons: "Vegetarian fare was much less than satisfactory. The only meal i enjoyed was the Indian vegetarian meal."

Pros: "professianalism"

Pros: "Private cabins in business class"
Cons: "Better control over boarding process"

Pros: "Good service in future always Qatar Airlines"

Pros: "Everything is excellent"
Cons: "All is well"

Cons: "Plane was too warm and movie selection was the same for all flights. Too many marvel kid movies."

Cons: "Food would have been better."

Pros: "Service & information"
Cons: "I didn’t get a hotel despite having more than 12 hours transit. I was told I don’t qualify for hotel stay but didn’t get the reason why"

Pros: "Crew . Food . Service was great ."
Cons: "Every things was good ."

Pros: "The crew was nice but never got the menu."
Cons: "The crew was amazing and delightful but should provide food to kids first before even those special diet or vegetarians."

Pros: "The crew was very cheerful and helpful even though I was puking my guts out on a long flight with a lot of turbulence"
Cons: "It was an insanely long and pukey flight. The airsick bags have this seal that you have to tear off before you can open it which my son discovered a little too late."

Cons: "Slow boarding while passengers stand in the queue, late take off"

Cons: "Great"

Pros: "Service"

Cons: "For deboarding they used stairs (not ramps) at their hub in Doha - must be some sort of new innovation to improve fitness. The Wifi onboard was in name only - it was so slow you wouldn't notice it is working or not - i flew Qatar because they claimed to have Wifi- hugely disappointed."

Cons: "I was moved from the front to the very back upon checking in at the gate due to "Weight and Balance" issues. I was able to move back to my original seat once in the air, but there was no forewarning of this even with advanced purchased tickets. Just a hassle since this flight was long and all I wanted to do was get some rest."

Pros: "Smooth flying regardless of the air wake turbulence, excellent treatment from flight attendants. I felt safe during the flight."
Cons: "Give more time for checking in the luggage, Cancelation my flight with 0% reimbursed on my funds, on boarding time 10 minutes delay was truly unfair."

Pros: "Excellent crew and food."
Cons: "No WiFi."

Cons: "I really didn’t like hke the Internet is free for just one hour. And how I cannot make international calls using the doha’s airport wifi."

Pros: "We carefully taken care . The Hotess were alright"
Cons: "Their food are ok"

Pros: "Food was great."
Cons: "Passengers in the back seat kept shaking my seat. I told them to stop, but they kept doing that."

Pros: "On time, fairly good food, good entertainment system."
Cons: "Very cramped seating when the flight is full. We're told to stretch our legs, but there is no place to walk or even stand."

Pros: "Great"

Cons: "I requested a chicken meal and I told the steward that I would wait because he did not have anymore at that moment. He never came back until it was time to pick up trash. I proceeded to tell him I never got the main course, he apologized and told me that there was only an egg entree left. I went ahead and took it, then as a way to apologize he offered to get me a piece of fruit, a banana. I accepted but he never came back with it. It was not a big deal but I did not appreciate being offered something and then no follow up. Next time do not offer something and then not follow through."

Pros: "The crew was friendly and helpful. And the food choices were good."

Pros: "very courteous flight crew"
Cons: "baggage took along time to come business class luggage came after economy"

Pros: "service, food and cleanness"

Cons: "The flight attendant dropped a suitcase on my head when I was sleeping. I had terrible headache, nauseous, and dizzy with some really uncomfortable neck pain. The staff tried to get me to take medicines that I could not read for nauseous but I would not. They said they were prescribed by a doctor! What doctor. The flight was the longest worst ever! 14 hours - nothing to eat or drink! In addition, the head flight attendant said the baggage compartment over my head was a problem as it opens all the way down and bags fall easily out. The bag was easily 30 pounds and landed directly on my head. I suffered a concussion."

Pros: "Great flight with good food and crew."

Pros: "Great Cabin Crew, the pilot was extremely talented and landed very well at a low speed so as to not wake everyone in Nagpur up."
Cons: "seats are a bit tight"

Pros: "Very nice. Everything was great."

Pros: "Excellent travel with Qatar Airways"
Cons: "Only thing is security was too tight at Doha Airport"

Cons: "The electronics ban on US-bound flights was handled poorly in Doha, resulting in multiple passes through the security check for many passengers, including two in my party. It left a bad impression that lingered, unfortunately."

Cons: "Service"

Pros: "The in flight entertainment was good"
Cons: "Service was not the same, flight attendants were not attentive or very accommodating. There were very rambunctious children on the flight and they did not consider everyone else by asking the parents to calm their children down instead allowed them to run up and down he aisles screaming etc"

Cons: "Seats were not very comfortable for economy class for a journey as long as these ."

Cons: "in flight entertainment interface can be improved to be more user friendly."

Pros: "this was very different nice service, crews with courtesy and ready to listen to any problem.Pauline."

Pros: "Ok"

Cons: "One crew member was a pain if you wanted ice you got 3 cubes ask for more he would ignore you. He was rud and nasty. I mentioned to other crew members they say just his way. If that is his way maybe he need find new job."

Cons: "I was Told the flight form Doha back to Houston was over booked so I had to get re-routed through another city. For a $6,600 business class ticket this is very bad form."

Pros: "Excellent customer service, smooth boarding, good food."
Cons: ""Enhanced" screening at Doha airport not only was more invasive but also held up passengers until end of boarding."

Pros: "The leg space is what got this flight a 3 star."

Pros: "Nothing."
Cons: "Was denied boarding."

Pros: "F"
Cons: "I have booked the flight for my mom and I requested a wheel chair her, she Has a broken arm . 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: "Everything"
Cons: "N/A"

Pros: "the best air line I've ever been"

Pros: "Overall flight was pretty good"
Cons: "Food wasn't as good as the other 3 legs of the trip (Houston-Doha, Doha-Kathmandu and Bengaluru-Doha) The hand rests on these planes didn't go all the way up making it less comfortable to be travelling on a 16 hour flight with a toddler."

Cons: "You do a sorry job of keeping couples in seated side by side my wife of 3 days wasn't even in the same row and there were at least three other couples that were done the same way y'all need to pay closer attention to the people that are buying your tickets"

Cons: "The food was great but I think they really don't understand what an Indian or any other food is. Although food was cooked nice they names the dish with some Indian name and in India the provided combination is never offered"

Pros: "Actual plane was in good condition and as comfortable as a plane can be. Very good selection of in flight entertainment."
Cons: "Flight attendants were rude and made you feel that you were bothering them. Beverage offered twice in 15 1/2 hours. Beverages when available if you want to ask the flight attendant, but again, they were definitely put out when you asked them. Caroline wasn’t kept clean throughout the 15 1/2 hours- i’m accustomed to light attendance walking through the isles periodically to get customers garbage regular league so that it doesn’t build up."

Cons: "Nice flight nice"

Pros: "Nice crew"
Cons: "Seat on up position are too straight"

Pros: "Plane was clean"
Cons: "The crew was uninformed and unobservant to actual conditions in the cabin. They kept the air conditioning on and no one was available to address the situation. People started to take their winter coats out of the overhead bins and sit in their seats with coats on. They spent a significant amount of time repeatedly requesting that the window shades be moved up or down. Frankly, if I buy a window seat I should have the option to look out the window if I'm not disturbing my neighbors."

Cons: "The crew kept waking me up and were rude."

Pros: "Great flight (considering it was like 20 hours we were traveling) Don't understand why we had to throw out the liquids we purchased past the security check points (like next to the gate). Why sell them then?"
