Offboarding in Dubai was a bit confusing. The bus dropped us off, we passed the security, and then we were again in departure, no clue, no guidance on where to get our luggage

Offboarding in Dubai was a bit confusing. The bus dropped us off, we passed the security, and then we were again in departure, no clue, no guidance on where to get our luggage

Flight and entertainment great. Food needs to be improved, only one choice on the menu. Staff worked well throughout.

Always enjoyed flying with Emirates, flown with others but they don't really measure up. The others are cheaper without a doubt, but not as good as Emirates

Both flights to and back from Lyon with buses taking extra time and delaying flight at DXB. Food serving needed work.

There is an issue with A380 when it arrives in Munich, because a business class passengers like me have to wait for the first class passengers to disembark, which takes some time while you are also offloading economy passengers this causes an issue at customs where your business class passengers end up behind a large bulk of economy passengers This is a frustration and the early dislocation should be and is supposed to be a benefit of business class

The journey was nice, all the crews were very good and services are excellent

in today's time, an airline like emirates didnt serve drinks as requested, Excuse was full flight.

Bathrooms were amazing and first class seat was very comfortable. Food was edible but not up to the standards of other first class meals on other airlines. But Caviar was amazing! So much caviar. Dom Perignon 2015 was room temperature. It would have been amazing if it was chilled down a bit more. Slippers were amazing and amenity kit requested was beautiful. Requested Pajamas never came so can’t tell you how nice they were. Loved the design of the seat and personal storage. Suite was much smaller than other airline’s first class and tv screen was tiny and remote difficult to use. I probably wouldn’t pay for this flight again.

It was delayed for 2 hrs. Flight attendants were not attentive.

We boarded but due to a technical issue we spent 4.5hrs on the ground waiting for the issue to be resolved

First off, it wasn't clear that my first flight was to be operated by IndiGO. While the flight itself was fine, this meant that my whole initial check in where I would've properly verified my seating on my Qatar flight/requested an upgrade was impeded by the fact that I had to check in with IndiGO. They said I would separately have to go to Qatar counter to deal with second flight leg issues, which was impossible given how long the check in took/no time available to do so.

Charged extra amount for the baggage wait. Even it’s less than 23kgs. Those machines are showing wrong weight and they were charging money wantedly from everyone.

Friendly and discreet staff. Could have done with a few more offers of water/snacks overnight. Movie and tv selection notably poor. Seats not especially comfortable

I am a big person and have back pain and swelling in my legs, so this was a challenging flight due to confined space. I didn't find the crew very friendly either. I will think twice before flying long distances with Qatar again, due to the lack of legroom.

I appreciated the vailability of wheelchair services for persons with mobility issues all the way up to the aircraft. What could be better would be the food choices.

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

Awesome hospitality, awesome staff, awesome food & awesome travel time. Thanks

The check-in and crew staff were wonderful. The food was reasonable. The online side Qatar was very poor. Seats were very tight and not very comfortable for a 14 hour flight!

First keep the airline as you promise. Reason for travelling from Orlando to Tampa is to go with Qatar Airline. We end up with American Airline. As expected the service was horrible.

Worse fight I ever take since I start flying , still have even made home , and crew abandon us half way home . No water no food and no even anyone to answer our questions

Majority of the staff were simply awesome and very very supportive and helpful

Surprised for charged $341.00 FOR my luggage. THY opportunist, taken advantage of the people not knowing luggage must be paid.. I flew 7 months ago with Lufthansa same place to Los Angeles my family lives and work in L.A. no luggage PAYS BIG zero .. I WILL NEVER TAKE ANY FLIGHTS ✈️ FROM TURKISH AIRLINES EVER AGAIN 😒 Please Don't recommend TURKISH Airlines to nobody.. I am a retired person. With very limited S.S. check for a month..$341.00 is my kitchen expenses for at list 5 weeks i am a vegetarian salads and sandwiches.. thank you very much for your investigation asking my experience about the flight with ROTTEN Airlines 😀

it was great honestly for the melbourne flight a kit with blindfold and slippers was probided to each passenger on the seat and the food was really great will definitely recommend people take turkish airlines for travel not just on the sin-melbourne route.

After arriving in Istanbul, the transit information on the electronic board showed a tight departure time, and the gate changed in the middle, making it difficult to make it on time.

Bad chairs in business class like economy ( not turning into bed )

The entertainment selection itself was ok but the screen couldn't be turned off which was annoying because I wanted to read and not be distubed by flashing lights in front of me. I could see other people having the same problem with their screens. The crew seemed to be too busy to be bothered by our questions/requests. I found the seat quite uncomfortable, especially for a long flight. As a short person, I've accepted the inconvenience of always having seats higher than comfortable, but my neck hurt after a while because the headrest was too high and couldn't be adjusted further. The seat pockets in this plane seemed to be faulty. I could see people near me having the same problem of everything falling on the floor because it kept detaching from the back of the seat. It was pretty useless to keep anything in it, even the menu and sick bag wouldn't stay in. The food was meh. The omellete was just a hunk of egg - my next flight leg also offered omellete but was so much better than this one.

Customer service was poor everywhere. In particular in business class lounge. Stewardess were however excellent. No ability to order more than one dietary restriction in food that created awkward situations when I was offered bulgur due to being diabetic as I was also gluten free

The worst experience I have ever been in, they canceled my ticket the very last minute although it was Booked since October! They claimed it was not possible to change the schedule till January 11, 2026 and all my plans were screwed! My wife paid cash upfront a down payment for a surgery she was going to perform on dec 27th, and all these money lost! I’m considering seriously to get support

flight was full and folks coming from Dubai all wear this strong perfume (OUD) which is annoying. Also, not sure why but these fools all stand up and get ready to bail once the plane stops. they seem to all run for the door which is funny AF. Plane was a 2 4 2 configuration and kind of an older plane with USB connection. Food wasn't that great either. Not sure i'd take this airline again since i have no plans on going to Istanbul again. Emirates is definitely better if you want to go from US to DXB,

nice and clean plane but the seats and the comfort was not what i expected. i expected more based on all the ads and reviews that i've read. I guess you get what you pay for in economy.

Terrible. Both flights were significantly delayed, no luggage, made me check my small bag when many, many others had much larger carry-ons, not even a bottle of water . . . I will not fly Discover Airlines again.

Layover time was not sufficient as the gate was too far, I had to literally run and was out of my breath. This was main drawback. The crew was wonderful and so is their service. I loved interacting with them.

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

Both flights were delayed over 1 hour. And I had to pay for seats, even though my reservation supposedly included free seat selection.

Boarding arrangements differentiated with groups, easy to follow. Seat size and leg room was very comfortable even I was with Economy class. Food was good and staff was nice. Very good experience even with 12 hrs long-haul.

food, movie entertainment upgraded current, interconnecting flights being on time, we have a 24-hour overlay

It was good service. The very low economic seats where not comfortable

It was very good, good food good stuff, The toilets were a little stinky.

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!

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious
