Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

Middle seats SUCK!!!! I paid more money than I should have because of your terrible site Kayak.com. I'll try to use your competitors going forward. I am so disappointed you would play off business class.com as business class seats

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

The plane was old Only 3 bathrooms available for economy The entertainment was old and the selection was poor

There was 2 hours delay before boarding and 2 hours delay after boarding while waiting in the plane

They again did not offer any functioning WiFi in the transatlantic crossing.

Good. Food items are ok but not really healthy (no protein for the vegetarian option, just a total of 2 gr total) so not fulfilling. Also, no airline is educating passengers to behave and have common sense: let the one sitting by the window pass first, leave toilets clean after use, etc. Humanity is just getting rude and more disgusting by the day and without education or enforced common sense no

Did not find the wheelchair that supposed to assist and went to a long queue for transit security chk which was very slow and boarding desk wanted to close counter although that they knew that I am minutes away because of their mistake of not providing the wheelchair.

Crew was professional. Boarding has few seats . Since the plane was not full would have been nice to change seat on the internet

Even though my seat is a paid seat, I was told to give up my seat to a passenger. I tried to ask the CA to negotiate, and when I spoke in Japanese, the CA fled. I had to find a Japanese CA and ask them to deal with it. . After takeoff, I spilled my coffee, and when I asked the flight attendant for a towel, she told me to wipe it off with a wet tissue. My clothes got wet, so I asked CA for an extra blanket, but I had to wait for an hour.

I paid extra for a seat with more leg room but they changed the plane and found myself in an ordinary seat. This is expensive at 50€

Great staff/service on board. Check-in/boarding staff are very good, but overall supervision of their passenger intake processes needs attention.

I have travelled many times on Turkish, but they always board at least 30-40 minutes past the stated time. If informed properly, passengers can choose to spend more time in the .lounge instead of standing around by the gate waiting to board. The new lounge at DFW was a big disappointment. The aircraft itself was a shock. In the past I have flown this sector with regular business class seating configuration of 1-2-1, The 2-3-2 seating is very disappointing after paying such high prices for tickets. The DFW to Istanbul segment was slightly better, but the Istanbul to Delhi segment was no better than premium economy. I will try to travel more on airlines which give business class passengers more value for their money.

This is not business class. This is premium economy. Total scam to sell this as business class

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!

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.

This flight was in the air when the national power outage happened on 28 April 2025 in Spain and Portugal. As a result Lisbon airport was closed and the flight was diverted to Porto. There were no phones, internet or ATMs working and the Turkish Airlines ground crew in Porto were trying to find alternative transport to Lisbon (by bus). This did not materialise until late in the evening. The Turkish Airlines ground crew suggested that passengers may find their own way of getting to Lisbon. That in itself is a failure of Turkish Airlines, but understandable as there were no means of communication. The Turkish Airlines ground crew also said that any expenses insured for travel to Lisbon will be refunded by the Airline through their website. Unfortunately, I could find no way to travel back to Lisbon other than to hitch hike with an Uber driver. Because no systems were available and no credit card payment possible I paid the driver 140 Euros in cash with no receipt as systems were down. I arrived at my Lisbon hotel at 23:30 (flight was scheduled to land at 12:30). Upon contacting Turkish Airlines for compensation they are not willing to do anything as I do not have an invoice for my expenses. They do not even consider the 10 hours of delay and inactivity on their part as a reason to provide any sort of curtesy towards me. I find their behaviour appalling.

My wife and 7 months old baby had a terrible experience traveling, we paid extra for bassinet they didn’t provided.she missed her flight due to late landing of the flight, they were unsupportive to my family due to that my wife and kid suffered a lot.

7 stars hospitality and an excellent service by the Turkish Airline entire team. Somehow, our membership numbers for mileage points were not indicated on our boarding passes issued at O’Hare Airport by the Turkish Airlines check in desk. During transit in Istanbul, I brought to attention of customer service Turkish Airlines. Please have our mileage points posted to our membership account from O’Hare Chicago to Lahore for both my wife Kaukab Shirazi Thank you

It is much better than other airlines but not the best for the price

Food was bad crew a bit nicer than other flights seats uncomfortable too

Flight and flight service was great. When a flight is cancelled, publish to all affected with email and txt. Explaining the way forward.

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.

The space was tight, hardly any leg room and the crew surprisingly were busy and did not take the time to attend to passengers, felt rushed. There was a delay for check in since the systems were down the airport staffs were accommodating

Good staff, good intent, decent entertainment. More seat space would always be of benefit

There’s lots of problem I faced from Bom to Doha that experience was worst I never faced before like this

Asian Veng meal have Non Veg items which is not ok. Pure veg meals option are too less and they have inclusion of Vedgan and Lactos etc... which is taste less

You're like a poor man's Emirates Airlines. The Asian vegetarian food was awful. The entertainment selection was very limited and not contemporary at all. The seats were cramped. There was no plug for charging my phone (I refuse to plug into a USB port - A security risk). The plane itself was aged.

I didn’t expect American Airlines. I excepted QTAR AIR LINES. From KAYAK we are booking so in the kayak site it showed qathar air lines but operating American Airlines. I don’t like .

It was very relaxing and staff were very quick to attend to any requests.

It was an old plane with seats not comfortable and with little space for the legs. I must say that the previous flight I had was amazing on a very comfortable new plane

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

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

Seat selection screen while online check-in could include free seats to choose from and show the options before we proceed. Currently, it is auto-allocated and there are no options for free seat selections.

Crew were very polite and quicker in service. Excellent cooling, comfortable seats and tasty food served

The staff was very nice and polite but it was very very hot and no ways to have some fresh air. It would be nice to have more time to sleep since it was a night flight

One thing is very important is you people not giving seat arrangement together to couple, senior citizen. You have to take care of senior citizen. Do not look about money. Money is not important everywhere. Make relationship strong is very very important. I like Etiyad air line out of all air line. Food was hot and delicious. Air hostess gave very good service, nice attitude, very good behaviour. I gave 10 out of 10 marks. Thanks Jivraj

I WOULD ADVISE NOT TO BOOK YOUR FLIGHT ON KAYAK. THEY SHOW BETTER FARES AND AFTER I BOOKED MINE, I FIND OUT THAT IT DID NOT INCLUDE LUGGAGE. i HAD TO PAY $800 TO CHECK IN MY BAGS.

Nothing was good everthing was hopeless especially your staff at indira gandhi international airport india.Everthing has deteoriated

Everything could have been better. What needed to be wrong with United went wrong

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.

Before the flight I received an email from LH that our seat were changed to other comparable seats. At boarding however we found our reassigned “comparable” seats were directly by the toilet. They sure were no “comparable “ seats and we were quite disappointed!

Poor communication from airline, didn't start boarding until 15 minutes after we were supposed to be in the air and there was no communication from anyone about a delay except the screens showing we were "on-time" and already "boarding" which finally updated 5 minutes after we were supposed to be in the air to "delayed".

Regular 3 across coach seats in “business” just empty middle seat

Prompt boarding, safe landing and they didn't lose our luggage. No entertainment and no USB plugs to charge phones. No food, though I might have been asleep.

Nothing -they cancelled the flight with less than 12 hours notice

I was served cheese that had mold on it. I brought this to the flight attendants attention and she informed her supervisor. They were apologetic and offered me a replacement, but I think that is extremely insufficient compensation given I ate bad cheese causing food poisoning for my birthday vacation. Both me and the flight attendants photographed the cheese, and I was told they’ll “put in a ticket” to ensure it doesn’t happen to someone else…….

What did we like? Nothing really...The food choice and quality were very poor, seats were uncomfortable, tv screens were dirty full of greasy fingerprints, some of the staff (Not All) were miserable, shall I go on???

Plane was very delayed. US agents unhelpful in connection flt and in seating. No real info given on delay.
