Airline reviews

Flight was delayed by baggage loading onto the plane. This was attributed to "inclement weather" (some moderate rain) which could be said to be beyond the airline's control, but the problematic part was that the plane was boarded and doors shut so that passengers sat in a cramped plane with rising temperature (full flight) for an hour. The airline was aware of the status of baggage loading, they could have deferred boarding to keep passengers comfortable.

Food option Hindu veg to Hindu non veg request was unheard

This flight was 16 hours and they made it very tolerable. Seats were comfortable and the staff very accommodating. I had plenty of inflight entertainment. Food was very good.

The crew and their service was top notch, but the plane itself seemed to be on the older side and worn out. Also, the food could’ve been better. 9 out of 10.

Service excellent would chose Singapore airlines as my first choice

Fantastic patience when one of the passengers behind me was an absolute horrible, horrible person and the girls just kept smiling and doing their job with patience and kindness. Well, done to the crew.

Excellent- a lot of food Disappointed with the premium economy pouch- did not have toothbrush and tooth paste or socks. Other airlines provide them

On time, friendly staff and decent food. Would definitely recommend.

My daughter and I had a pleasant trip to Singapore. Reliable and on time.

Didn't like much at all Nowhere near enough legroom, narrow seats. Aisles not wide enough for safe food trolley access and husband had his knee hit cos not enough leg room. Would take a lot to convince us to fly Singapore Airlines again which is a pity cos it was always our go-to airline

better announcing at the gate prior to boarding and better organization of various gps

The plane was good - on time! But can the stewardesses smile or actually be nice - not to bark the commands

Edelweiss is now Nickle&dimming, not even a complimentary wine on the intercontinental flight. Sitting space is the smallest I have ever seen.

Excellent Airline. Food, crew and comfort was perfect. Entertainment screens were old. Didn’t like them.

I never share this kind of things but I have to share this out of respect to myself and how surprised I was I got a shoulder injury so I went to Turkey to get a procedure to my shoulder ( I can prove and provide it with documentation from the hospital to you) and on my way in this flight, I asked one of the crew members who’ s name is j. Muller to help me to lift my carry on to put it up in to cabinet and she told me she can’t do it , and I said I m sorry I m injured , I really need help , then can you please find someone who can help me ? And she gave me this nasty attitude and refused to help me . Then I was shocked because all I asked was for help, i didn’t even ask her to put my carry on bag up for me , all I asked her to help me so we can do it together. Then 5 minutes later another crew member who’s name is Jenny Rutz came and asked me if everything is ok And i explained her what happened and she told me if I create more problem, she will not let me fly i was shocked, all I told her was I was injured and I needed some help to put my luggage up . I am extremely shocked and upset , this was so unprofessional, rude and unnecessary. I thought their job is to help us in our flight. She disrespected me , embarrassed me, made me feel like I m a problem and threatened me to get me out of the plane In front of everyone I am 41 years old mature and kind woman, i have never in my life experienced something this unprofessional and this disrespectful ever They both turned something so simple and normal into this terrible experience for me and for the people sitting around me . So it was so uncomfortable and unfair that the other passengers who were sitting around me and next to me got negatively affected by the event and told me to take their phone number so that they can be my witness for the crew member’ rudeness and unprofessionalism I m still very upset how can people be this rude and heartless I will never ever want to fly with your airline company again

It was the first time in my life (I’m 54) that I’ve had to pay for drinks on an international flight. Very disappointing. Also, the baggage fees were very steep. I’d rather pay for everything in the price of the ticket than be repeatedly charged for add-ons.

It was not made clear that additional passport control is needed before queueing up for boarding. The seats were very uncomfortable and cramped even for small persons. The arm rests were not fully capable of lifting up out of the way and the media controls cut-out made them even worse to lean on. Just one audio channel was working on one of our seats.

Flight was very full and we had to checkin our carry on. Stuff however promised us that our luggage will be the first one to come out and it did

They rebooked our flight and then canceled our trip halfway through the journey without any explanation. Needed to pay by ourselves for alternative flight options without any help from Swiss.

Flight was diverted from Firenze to Pisa causing delay and inconvenience.

Qatar Airways in-flight first/business class service is superior to any US airline; excellent meals are served on short haul flights such as between DXB and DOH.

Do not overbook flights and kick out confirmed ticketed passengers :-(

Wasn’t allowed to continue with the purchased tickets because I hadn’t been able to go on the first scheduled leg.

The rows of seats in economy class are seriously close to one another making eating and resting just about impossible - there is hardly any legroom. Anyone larger than average size would have an incredibly uncomfortable flight. I had to basically share my seat with the lady passenger next to me as she was too big to fit into her allotted seat.

Overall experience was OK. Seats were truly uncomfortable for such a long flight. Food quality was mediocre at best. The staff was great though!

Staff was very friendly. There is no on board entertainment, but it’s such a short flight that it doesn’t matter. We also got a meal which was nice and unexpected due to the length of the flight.

Food was good, attendants were friendly. Seats were not comfortable. Did not receive any amenities such as eyemask or earplugs that would have helped sleep. Additionally a large group of passengers boarded very late into boarding and were a disruption for almost the whole flight. Flight attendants did their best but the kids were making so much noise, kicking seats, and half the time no adult was sat with them so they weren’t being managed.

Qatar airways from Doha to guangzhau was excellent big bird Boeing 777 more room and smoothly flight, I Love it

The made us waiting and held our passports and boarding pass making us miss our flights

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 😊 🙏 😀 😉 👍

Liked - efficiency of boarding with 2 jetways. Checkin was with kiosks with helpful and plentiful workers to help with the process. Munich airport security was very automated, efficient and effective. Free wine and beer! Cons - food was only okay in economy class. Plane bathrooms could have been cleaner.

Crew were friendly and very helpful Plane was clean and the legroom is standard. Overall a good flight, no complaints.

The seats were extremely uncomfortable. I spent €25 on internet and never gained access to it. A flight attendant told me she would file a complaint/report on my behalf but it put me in a very difficult situation.

The connection to LYON was very tight. The flight was nearly finished boarding when we got to the gate

Two things to note here. First, Lufthansa separated me from my small children. Apparently you need to pay extra to ensure that your children are not abandoned. This is different from KLM-Air France, where children sit with their parents automatically, and I usually fly KLM-Air France. I didn't realize Lufthansa was different on this score and is willing to leverage the wellbeing of small children to generate more revenue. Second, my flight arrived 3 hours and 54 minutes late, so I am entitled to financial compensation as per EU passenger rights regulation. From other aspects of Lufthansa's behavior during this trip, I expect that their approach to this is to start a war of attrition with their passengers to avoid giving compensation as much as possible - again, very differently from KLM-Air France. But we'll see, maybe I'll be pleasantly surprised.

I did not like that they failed to put my luggage on my connecting flight to Athens. I was promised it would be located and delivered within 2 days but later told there was no information on its location. This caused me to have unplanned for expenses because I then had to purchase new clothing to wear on my vacation. I did not receive my luggage until my return flight home. I will not be traveling with them again.

Absolutely the most awful experience in the history of service from gate agents to baggage handlers. Never will i use kayak or Lufthansa again. Ever.

No internet, very narrow seats insufficient room for three passengers with encroachment.

This flight was operated by Air India and it was good experience

was having emergency they keep dalying the flight I miss hull my trip and united airline charges me &100 for bags and I spent more thin $320 at airport for my family and when I get back samthing Daly my flight in muc I lost flight in Chicago I spent another &220 at Germany airport for no reason I should get refunded it’s very hard when total off us 7 people buy food at airport

Flight was fine, food better than anticipated and flight attendants were helpful and friendly.

Flight was fine, food much better than anticipated, and flight attendants were helpful and friendly!

Our headphone plug is broken, we can not enjoy our entertainment, especially traveling with 5 year old who like to watch movie

Reasonably comfortable. Plenty of room. Crew were attentive and continually informing passengers of position. Although stuck in runway for 1 hour, weather issues, it felt like we were the crews first priority

Need a do not disturb sign if you wish not to have any meals so that they can wake you or have the meals served . Left very sad and hungry .

Pleasant, attentive and efficient flight attendants. Boarding process and seat selection easy. No internet on transatlantic flight. Extremely uncomfortable, rigid seat.

No entertainment and the seats are well worn.! To the point it feels like your sitting in a bowl

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Everything was fine except not posting the gate number until 14 minutes before boarding. In an airport the size of Heathrow, that was unacceptable.

We already had a five hour layover in London, and then they cancelled our flight about half hour before we were due to board. They wouldn't give us access to the lounge and hanging around the extremely busy terminal for another three hours until our next flight was crappy. 8 hours in a busy terminal is awful. The least they could have done was give us access to one of their quiet, comfortable lounges for the inconvenience. I heard from others that they do this a lot -- cancel these short flights if they're not completely full. When we got onto the next flight it was absolutely packed and uncomfortable. Just very disappointing. British Airways used to be a great airline to fly with, but it doesn't feel that way at all now.
