My experience was wonderful. The professionalism of the crew was exemplary 🙂. The meals were wholesome and tasty. I have no complaints

As an ex airline employee in my home country of Jamaica, it was wonderful to see that Swiss Air has maintained it's exemplary service. The crew was both pleasant and professional. The meals were wholesome and tasty. My brother and I traveled and we both agree that our amazing vacation started with the excellent experience with Swiss Air. Continue to keep your standards high 🙂

We flew an Air Bus 330 airliner from Zurich to Boston. Our seats were terrible. I am 6'5" with long legs. I tend to refuse paying extra for extra seat room, usually it's tolerable. We were side by side in row 40, with my wife in the window and me in the aisle. The internal arm rest only rose to 45 degrees, I thought it was broken. I ended up standing by our seats in the aisle for an hour. A stewardess finally approached me and asked if I was feeling sick. I told her that it was the worst seat comfort I had ever encountered. She left and shortly came back telling me that there were center row seats two up from us where only one passenger was sitting out of the 4 seats. I took her advice and sat there most of the flight. I put m legs sideways in the adjoining empty seat. But the arm rests there as well only rose to 45 degrees, so it's a feature, not a defect. The arm rest position really limits our position. It's a horrible seating design, what are the air craft designers thinking?

Swiss is the. Only airline I use when I go to Europe. They are on time and they are fantastic!

The flight did not take place because the flight was canceled and I still have not received a refund for the flight.

The cabin was warm and few used the blankets. I should’ve upgraded.

The plan was delayed for takeoff by an hour, but we ended up making the landing on time which was a nice surprise.

Poor. Seats uncomfortable. No leg room. Hot and humid the whole trip. Food and staffs were ok.

The seats were so close together, when the man in front of me put his seat back, the screen in front of me was 9 inches from my face. There is no way to lean forward if I needed to pick something up. It was pretty uncomfortable for a ten hour flight. I was very surprised.

Crew and food was good, ok leg room if you don’t have a big box under the seat. And the seats are so narrow (I’m only 70kg), will consider an alternate airline next time

Food was absolutely pathetic. I wasted so much food which I thought was inedible. I also loathe the inflight entertainment system which has very little content

Boarding from DOH to SYD the Business Class were pointed in a separate gate but no one there to receive us. Otherwise it was ok.

Good. It would be great if comfort seats were available

Awful plane to Tashkent. Not even possible to sleep. In business class does not even recline fully

The staff was the best I have experienced as a frequent traveller in a long time.

I was unable to pre purchase sear upgrades or internet. Their online site is not user friendly and poor. I felt singled out in customs. Seats are very small even for a small person.

Qatar Airways did a very good job. Flights were slightly delayed with boarding but pilots made up time by arrival. The food was OK, no better or worse than other airlines. Although it would be nice to have three meals during 16 hours flight instead of two.

Well organized boarding, efficient and on time. Nice crew on the plane. Thank you!

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.

The WiFi was not compatible on both my phones (Vivo Y30 5g and Samsung Galaxy A32) with up-to-date android software.

Boarding was excellent except they did last call 30 minutes earlier .

It was worst flight ever of 26h. Poor service and seating. Flight from Abu Dhabi to Islamabad service and seating was worst ever. No tv extra.

The check-in has been the very best so far I didn't get to use my priority access which made me feel like a paid a higher price with no benefit for that I loved the food Very tasty and hot The staff friendliness, empathy could be better as it was not linear amongst the whole crew Otherwise, no complaints. I'd still fly again via Etihad Great prices despite the long 6h of waiting time

Surprised at the lower quality of seats on the Boeing 777 in Business Class. Seats are tight and the whole Business class section is jam packed with seats. It doesn’t feel like Business Class at all. Also the way the tray tables are placed with a huge bulky solid metal hinge at knee level makes it so uncomfortable and always anxious that one will accidentally bang their knee on it. Quality of amenities has also declined. Over priced tickets with diminished quality of the entire experience.

It was OK as the seat which we paid for doesn’t have any window. We paid $120 for 3 seats but it’s for nothing. Crew could not help. None of the ports worked so all our phones went dry

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Horrible. After paying for my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through American Airlines but will avoid in the future.

Extremely bad food, they never gave our bags in time, the online check-in did not let us check in because we had Indian OCI not sure why we were given the option to check in then, because we couldn’t check in online we had to go in person and we were not able to change our seats and sit with our family

The flight take time was changed 23 times. The system kept sending messages it will be earlier at 4am and eventually the flight was at 9am I didn’t sleep all night because of that

The staff at IST airport could have been more helpful. Too much wasted time and the plane from IST to KHI was just horrible. The plane was not clean and smelled bad!

I liked the overall flight experience. However, Turkish officials could do a better job at guiding non-Turkish speakers to their connecting flight gates in such a huge & vast airport.

Staff friendly. Business class but issue with flat bed. Incoming Turkish flight delayed. Made connection due to fast buggy but luggage did not make it. Confusion at Delhi airport

The prices and many to choose from: Very unfriendly unprofessional and difficult staff and lacked English skills. Had the pleasure to go to Istanbul in 2022 but went on Jordan Airlines and found Turkey a wonderful place with kind people. The experience as a first time flyer on Turkish Airlines was so disappointing that received not to go into Turkey was so upset about this cruel treatment

Terrible. Delayed. No one would help. Just limped about like a piece of meat

With a 4 hour delay its was a very basic flight which was just bearable. We were offered food vouchers for the delay and then they didnt work, so that was annoying. Also poor communication about the delay which got pushed out 3 times.

This is really the rating of two flights. JFK to IST then IST to NQZ. New York to Istanbul was good. Good crew and all positives. The flight to Astana was so bad that brought it all down. Crew was nonexistent above the minimum, seats were cramped, and it was hot on the plane. Turkish Airlines seems to be slipping down to US based carriers level.

The business class seats are designed for someone taller than I am, so my feet were dangling (the footrest was just a smidge too low). Which caused problems with my sciatic nerve and made for a long uncomfortable flight.

Amazing trip! No delays, no broken or lost luggage, and amazing food.

I use a wheelchair for mobility. Both in my flight from Houston and back to Houston from Istanbul, the Turkish airline staff asked that I claim my wheelchair at the luggage area. On arrival to Istanbul, parts of the wheelchair were in disarray at that time I raised no objection however upon claiming my wheelchair in Houston parts where outright missing. In both occasions, upon arriving in Houston and arriving in Istanbul, I asked multiple times why am made to pick up my wheelchair in the baggage claim rather than at the jet bridge. Getting the wheelchair at the jet bridge minimizes the probability of loosing parts because they can be hopefully reclaimed on the spot. I was told in Houston that a manager turned down my request to claim the wheelchair at the jet bridge in Houston. This is extremely frustrating because a wheelchair is not a set of clean underwear or a toothbrush- this is the way I move. A Turkish Arline staff took my complaint at the luggage claim area in Houston but as of the writing of this review the only contact I have received from the airline is because I initiated a claim rather than her as she told me she would.

Luggage transfer in Chicago was not performed in time. I received my luggage at my destination two days later.

Booked Economy but it translated to economy light for Lufthansa so now we are stuck paying an extra $75 per person both ways for our checked bags. If I had known that, I would have never booked these tickets because it came out to be more than other options. The booking in the kayak side clearly says Economy and has a link to the inormation for Lufthansa which states Economy included a checked bag. Super annoyed about that.

The seat I was stuck in was so unimaginably uncomfortable. I have never had that tight of a seat in my 20 years of flying. Even budget airlines give you more space.

The pasta in the evening meal was tasteless. Otherwise, the flight was okay.

Seating was average for a first class seat. It very modern. I expected better.

Flight was 1.5 hours late to depart so changed flights to Swiss Air.

Excellent flight overall. Lufthansa Business service was excellent with great cabin crew and very good food and wines. The seat comfort was excellent. Only a slight reduction in score due to the 747-400 being a relatively loud aircraft these days.

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

I was very happy with everything, thank you for the smooth flight ✈️

The flight was about 10 minutes late which made it kind of tight for connection in Frankfurt. One think that was helpful for my husband and I since we don’t speak the language was when we got off the shuttle bus, two ground crew told us very clearly how to make the connection.
