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.

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.

As good as you can expect an economy flight from Europe to Australia to be. Nothing agains Qatar, just feels like every new generation of plane gets tighter.

My entire row did not have power for the full duration of a 14.5 hour flight. Could not charge any devices such as laptop or phones for the entirety of the long flight. The flight attendants tried to remedy the issue by resetting the power, but were not successful. The only other solution provided was to move me to another seat on the plane which was in the middle row. I had paid for a “preferred” seat that was a window seat. This was a downgrade being offered due to the power issue.

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.

Liked some flight attendants. 1 was rude I'll not say her name I don't want to get her jn trouble on my flight back to Dallas from Doha. Very rude to some races of people clearly. She needs a better attitude and bedside manners. Asking her questions and she responds "WHAT" twice rudely like I was bothering her and "is it going to be cranberry or mango juice with an attitude".

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.

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

No difference between US airline and Qatar. Both cramp as many people. The airline seems to change planes without notice choice is seating when making reservations online doesn’t match the plane a passenger is on. Especially paying extra. Nothing special No different than US carriers.

Aircraft was spacious compared to American Airlines, food was great, entertainment was much better with a wide variety of options, and the crew was very polite.

The flight from Abu Dabhi to Bangalore was terrible. The plane was an order model with no onboard entertainment. The beverage selection were very limited.

excellent, staff and boarding were all seamless and no issues, thank you!

Wish the flight attendants were more attentive in serving food

More leg space than other flights, but *maybe* narrower seats

Very delayed and uncomfortable seats. Nothing written in Urdu for Pakistanis. Tons of Pakistanis use the airline they should ensure the airline is accommodating them properly.

My baggage was not boarded and is still missing. I was only carring one piece of luggage and that is misplaced now I am stuck at mumbai without luggage. I had an onward journey from here

Etihad charged me for 2 check in bags. On Kayak search results price was showing 2 check in bags were included. Kayak need to reimburse me for these additional charges and metal agony and distress. Thanks.

Will never book any flight from Kayak and will never travel ithad airline

In Colombo when I-drop my baggage Sri Lanka air line crew not polite way talk very rude

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

Not consistent with the food quality (I mean taste not freshness)

Food was really mediocre for premium economy in comparison to other airlines… the crew was nowhere to be found… 14 hour flight…

I don’t like that an equipment change caused my seat to change from 23A to 44A. The boarding was also delayed. The crew were excellent, however and very attentive. The food was not bad.

Our flight crew were terrific. And they handle a difficult passenger with finesse.

Excellent, Lima to Paris. But Paris to Amsterdam, delayed, missed my flight and KLM treated its missed flights passengers very badly, terribly bad. No hotel accommodation given. Passengers were told to find their own hotel accommodation and claim at reasonable rate and left the booth and literally with armed Police Officers listening to passengers complains. For three hours, after moving by Uber from hotel to hotel and calling and booking online, no hotel was available. I had to return to the airport and seat/sleep on the benches, suffering the cold, and rats running around until my new allocated flight the next day. It was the most terrible KLM treatment even seen and being a Business Class passenger. Still mentally suffering to date as a result.

3 hour delay but out of their control. App said I get vouchers but when I applied for them, they were nowhere to be found in my account

I bought business class tickets but the seats are exactly like economy with no comfort seats nor an empty seat next to me provided. Very poor, low quality airline.

I don't understand the concept of paying to get your personal luggage onboard and then asked to check it in.... either sell the space or don't, its a hassle to carry those all through the airport just to make a check in at the last minute.

The food was great and the service and attitude was amazing!!

Old airplanes small seats expensive tickets, not as expected overall and not comfortable according to the price

the flight was cancelled and I was rebooked twice, once 26 hours later, then another 24 hours later. In total the flight was delayed for 40 hours. Never again will I use kayak or Turkish Airlines for my travel.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Food is very turkish. No regard for other natinalities taste and preference. The entertainment can be improved- it was the same menu on 10/8/25 and 10/25/25. The boarding is the worst in the airline industry- I suggest you ask your staff to and watch how other airlines do it.

Very small and cramped aisles and seats. Food was poor but the fresh hot roll and hummus was good. No cans of soda given but they had small bottles of water. Crew was nice and pleasant and kept bathroom clean.

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

I loved and appreciated the agent at the check in counter in Amman. He was very professional and helpful. I believe his name was Lawrence. All I saw from him were smiles after smiles after smile. Very kind and professional. Overall trip was comfortable and pleasant.

Absolute worst airline. Charged us $720 to check 4 bags (2 of which were carry-on). Entertainment systems didnt work. And on a 12 hour flight they served 2 meals and never once came around outside of those 2 meals with a beverage or cup of water. Will never fly them again.

The 2 agents on the check in counter were super nice , helpful and very polite. Boarding was like a 1 2 3, I would recommend Turkish airlines for your next trip.

It was an old airline with the old configuration of business class seats. Not really what we signed up for for the longest leg of the trip. Disappointing.

flight with heavy turbulence old boeing 777 rest wasnt clean dashboard doesn’t work

Airline food is airline food, but the plane was wonderful and the seating comfort outstanding. One of my best flights in quite a while.

The seat space seemed small especially when the person ahead reclined but other than that, very good.

The service and flight was great. Luggage came out very quickly!

Flights were delayed but very last minute, also seats felt very squished on the second flight. Crew was very friendly and airplane was clean.

Very small and uncomfortable seats, Hard to hear entertainment system sound. Horrible food. Staff doesn't care much about the passengers. 2nd time they didn't give me my vegetarian meal. They asked me regular food with meat. The airline and staff was from United airlines.

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

This is my second time to fly this year with Lufthansa and both times they dropped the ball. My ticket was very cheap and l would not be honest if l said that l had some high expectations for that price. Fly delay 6 hours. Screen in fey seats around me didn’t work. Food for dinner was ok but breakfast was so poor. We had connection in Frankfurt for Vienna. Because of delay they gave us fly with 30 min layover time. We got to Vienna but our baggage was late of course. Long story short it took us almost 24 hours to get to the final destination. Very bad experience

The flight to Frankfurt was delayed. Consequently the connecting flight to Seattle could not be boarded. Lufthansa accommodated in a Cattle Class Flight where the Seats and foods were horrible. I had only Hobson’s Choice and boarded the flight and reached Seattle 3hours later than my scheduled arrival.

No Wi-Fi or food unless you pay an expensive fee.

A major problem at the Frankfurt terminal. You see your connecting flight is on concourse A and you see signs for A, but when you start to walk out to A, only then do you find A is in another terminal which requires a bus ride, passport control and customs. If you sit around in the first terminal too long, you can miss your flight. We made ours.
