My overall experience with Singapore Airlines is great. Will definitely fly Singapore airline again.

All in all the flight was good. Love the fact that for airline food it was piping hot

I requested an aisle seat and got a middle seat The flight gate was changed and the flight was delayed

They made me check my carry on even though there was room We un boarded in a strange way but overall it was good

Seating cramped; close to toilet, foul smelling and noisy, very unhygienic and disease risk Free and paid Wi-Fi NOT accessible at all - misleading advertising Very expensive sunglasses disappeared from back seat pouch. Coffee disgusting and cold

The premium economy seats were not that great. It could have been more premium than economy seats.

The singapore airline now compared before covid, I like the service before covid. SQ was the best of all airlines but now I am going to look for different airline if I am travelling in asia.

A pc of cake or biscuit at least. The airport was like a maze need to take another bus to the main terminal to immigration.

Flying with Singapore airlines is always excelllent - the crew are lovely and the food too is great. It’s my number 1 airline

Perfect experience from boarding through to leaving the flight, comfortable and personalised service from all staff, highly recommended

I liked everything accept the delay try to improve in that area

Flights were both delayed. No luggage on arrival for the whole plane and no contact since submitting a PIR.

I am going to be just factual, not bad mouthing nor complaining, but this was my experience. With 3 pieces of luggage, I was told the flight from Mumbai to Dubai was cancelled due to flood. This was told not by the airport board which still showed the regular time of departure, but general stuff at the airport. No Emirates stuff around to direct the transfer passengers of the cancelled flights. By the departure counters with crowds of people, one by one, angry, frustrated, urgent conversations were going on. No announcement were made, no postings being seen, just private conversations. I still have 5+ hours of layover, so I let more urgent people settled first. However, the fact that no communication of when, what and where I should go was very unsettling. Basically no time limit waiting means, no meal, no sleep, no step away, no planning, no change plan, no telling of the family what to do. Nobody was able to tell you anything but asked you to wait, no chair, no space, no facility to freshen up. That went on for 10+ (from 5) hour without warnings and accurate communications. Email received from Emirates asked me not to go to Dubai at all, or boarding at the time that was passed. In other words, communication were very untimely, after the fact. That created more confusion instead. After changing several of boarding time, we were given the gate # and a boarding pass. However, the boarding pass still have the original time of boarding, so again, not knowing walking 30 min in the airport to the gate would make you late or not, therefore, still dare not to eat a meal. The flight arriving to Dubai was uneventful and I gave a 4/5 rating. I just thought the layover at Dubai would just cut short from 8+ hours to 2+ hours. At Dubai airport, I saw people sleeping on cardboard, knowing, these people got stranded but they dared to sleep because they know when to board and I didn't. Or these kind of delay are just so normal that people know what to do to pass time. Then the worst service and crazy thing happened. The boarding time on board for LA and at gate A9 was clearly 8:50AM. At 8:40, surprised by not having any boarding activities, then one single staff showed up and said to a few passengers that the boarding would be delayed without a time frame. Since only a few people know, I asked another Emirates staff at another counter, who simply said basically non of his business. I was shocked with that indifferent attitude. Yet every boards I saw show the same boarding time. What kind of system failure was that to prepare delay situation! How confusing and unnecessary chaos and anger that provoke. That poor staff had to repeat himself so many times, answered questions that he had no power nor information to provide nor solved. One an only one stuff to show up for 10 min, leaving the counter non-staff with board showing 8:50AM boarding. This was purely irresponsible from top to bottom of the entire airline operation staff. What kind of leader in a service industry would allow this to happen to their customers. Without explanation, after changing 3 times the boarding times, again, means you should not go to eat a full meal, because, when you found a mob at the gate. People who were stranded for 2 days were afraid of not getting a seat with a full plane. That would not be happening if the airline provide adequate guidance to each person, instead of just having 4 staff yelling at the gate at the same time to "control" the crowd, threatening no boarding and delay boarding. Finally, I was on board, hungry and tired, not sleep for 36 hours. I was denied with a snack of fruit. By the time meal was served, it was an hour later. Half way of the trip, I felt sleep in fetus position and did not want to move, happy I finally could have some shut eyes time. However, when I got up to the bathroom, I felt very light headed. Having sleep deprived, constipated for 3 days, dehydrated, I knew it could happen since my blood pressure usually was low closed to 90/60. Any lower then that, I could have syncope. Sure enough, I was on the floor just 10 feet from my seat and 5 feet to the bathroom. However, nobody called for help. I asked for warm water and juice to hydrate, came only with cold and icy drinks which I wouldn't take. I asked for blankets, one was given. Yet my shivering, needs to cover my head and multiple requests did not hasten to take the two blankets that are at my seat 10 feet away. I waited 10 min for that. While 2-3 staff surrounded me, nobody did the vitals until after 15 min, just the spirometer only of which did not work due to my cold fingers. The first reading was 86 and oxygen was suggested. But another supervising personnel came, fussed over another reading, ignoring my comfort and needs. Seemingly the reading of spirometer was the priority. By then, no oxygen needed. I had this fainting experience before, and I knew how to help myself. However, I was not being listened to but to be told this and that. Finally, I got better and returned to seat. One kind flight attendant said she would check back with me in 15 min. She did not come back. I felt asleep in that fetus position again and this time I woke up with a bad cramp at my left leg. Yet I needed to go to bathroom, the cramp was too bad to walk. So I stepped back to seat. When I tried again the second time, the other front leg got cramp. This time I dare not move but massaged myself. For all these 5-10 min, I called for attention. Attendants passed me by because they were carried with heavy load of blankets and stuff. Nobody answered the light. Then came landing and off board. I was asked by two attendants how I felt. I smiled and said "fine".

Nice selection of movies and TV shows. Plane was generally nice, not the newest but nice nonetheless. However, Emirates should have cancelled the flight, as hardly any flights flew out of Dubai at the time. Flight delays and cancellation was poorly communicated and passengers were left guessing and to their own devices on what to do. Connection desks were staffed too thinly, there was one desk with more than a hundred clients and just one poor lady. When I had my flights rebooked, I was told meal vouchers can be scanned using my boarding pass, nope. Was told to comeback for my hotel voucher, none. Had to book my hotel voucher the usual way through Dubai Connect despite having been told twice to comeback to the counters twice.

On the Dubai-Gatwick flight the only meal options were Beef or Chicken. No vegetarian option. This was a surprise. I would usually order in advance but did not this time. Would have been good to know that a vegetarian meal is not available as a standard meal. Thankfully it was just me travelling, but if I’d had my kids with me that would have been a big problem for us.

Didn’t like it at all. Cabin crew unfriendly. Very bad experience.

Food is really bad, not to the Emirates standards. Coming out of Houston airport is very confusing,

Absolutely terrible delays for 3 hours changed seats after we paid an upgrade on both legs. It appears it’s up to us to request a refund after they down graded our seat. Never again !!

They had superb boarding (started an hour before flight time). Timely pushback from them gate and an early arrival. Flight and service was very comfortable. I wanted to move my flight to an earlier one, only thing was there was no one at emirates in Heathrow to help. Had to call the call the center and pay to change. There were ample seats on the flight though

More leg room and comfortable seats at least for long flights

Operated by American Airlines. Very chaotic and the crew was bit rough responding any enquiries. Restricted leg space.. Qatar would have been better

More facilities to transport to the gates......felt too much walking distance

I staff or crew they were very friendly and humbly, they done theirs service very well, I appreciate them and thank you to the company or Qatar 🇶🇦 Government for providing as good service in their flight ,once again, thank you 😊 🙏 😀 😉 👍

Online check-in doesn't work. That's why I couldn't give it full Star.

Overall it was a very good experience. Boarding was efficient and well organized. The cabin crew were excellent. The meals were tasty and quite filling. The warm bread rolls were a nice touch. Seats were comfortable even if they were a little narrow. Entertainment selection was excellent.

The crew was courteous and efficient. There was no entertainment or liquor service on this short international flight.

No separate queue for business class/platinum passengers. I had to stay in the long queue to board. I requested breakfast before landing, but the crew didn't offer, except a coffee with milk. No tea with milk was available. Had asked for cookies, but didn't receive them. The crew in the business class was not good in terms of service..

Crews are very rude and unhelpful. Cramped seats in economy. Foods are useless

The business class experience was awesome - I will be using QATAR airways again and it'll be business class again - appreciate the privileges afforded to the business class clients - thank you.

After going through security and waiting for the flight at the gate, there was no access to bathrooms and no place to charge a phone while waiting for the flight. But once I was on the plane, everything was very good.

Comfortable seats. Be aware there is no alcohol on this airline.

Seats were comfortable. Be aware there is no alcohol on this airline.

Every thing was very food except the meal. It was a sandwich of something like a beef kebab. It was really bad in terms of hardness as well as taste. We were a family of 7 persons non of us could eat it his sandwich. Cake was good.

It was very nice flight only suggestions to upload recent videos and English subtitles. Thanks

Wheelchair service is not available right away on Kuwait Airways

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

Food quality should be upgrade. Plastic spoons looks like not good as well as food quality not up to the mark.

Everything was great specially the seats was comfortable even I was in the economy and the food was really Great👍

Not much on entertainment, food was good but not delicious, flight was on time

The crew was attentive and kind. The business class cabin wasn’t very full during the flight so the service was catered to your specific needs.

The flight was delayed for almost 5 hours, but I understand that it was not up to the company, however how they could handle the situation better, they never apologized for that delay, moreover despite passengers being there for 7 hours only thing they did was to give a bowl of instant noodles, afterwards on the plane tiny snacks, people were there starting from lunch time and we’ve arrived to destination at almost midnight

Flight was delayed for 2 hours for no reason, then we spent almost an hour after boarding because of the weather conditions. If we left on time we could avoid that 😾

Cons: "Everything was great. Very nice and friendly crew, clean plane, great food. Excellent overall"
Pros: "Because of our delay, we flew with Air Thai instead of Air China....much better airline"
Pros: "The crew was accommodating during the flight but spoke very little English and could not help with information on connecting flight."
Cons: "We missed our connecting flight due to a delay and the airline would not let us through because we could have made our second flight...."
Cons: "Even for business class there is no TV screen on each seat. Just one small TV screen on the ceiling for a few rows to share. It would be much better with TV screen on each seat. I was sitting in the first row business class and the air hostess skipped me and didn’t give me a slipper. She gave me a used slipper at the end only without a packet. This is unprofessional to treat a business class passenger"
Cons: "Seats are narrow, leg room limited, and food is minimal."
Pros: "The crew was okay. The seating was great on all except for one leg."
Cons: "On one leg, it must have been an older plane, because the business class seats barely reclined."
Pros: "Beautiful new plane, professional crew, totally decent food."
Cons: "Economy for 13 hours is always a bit rough, but no more so on Air China than any other airline. And the price was so much lower."
Pros: "Boarding was a breeze, flight attendant onboard we attentive, choice of food orders at least two (in business class, can’t speak to first or main cabin passengers.) Flew from LA to Tokyo. Coming back from Hong Kong to LA. Fantastic flights, will use them again."
