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

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

The staff was great and probably that's the single most thing that distinguished this particular Qatar flight from my average typical experience. They genuinely wanted to please you and do their best.

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".

This trip was the most comfortable one I have ever experienced, the team was excellent and very helpful. I am so glad I picked Qatar Airways.

All the crew members were too slow and rude. Most of the times the registers were empty, while hundreds of customers were waiting in line, and it was impossible to get a supervisor. Despite being in line on time, I missed my freight, plus a some customers who were ahead and behind me.

I was denied lounge facility at airport. Explanation was not satisfactory.

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

The only thing that could have been better, is that the food trays get left way to long after a meal. We had a snack 8 hrs into the trip, and they left us with the boxes and cups for way too long. It is not fun being trapped in your seat unnecessarily

Delayed my flights and no communication. We end up spending 6 hrs in Doha. No food or any concern from the airline. Terrible

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

I hate to have pay for my first luggage 165$ when I did my search on Kayak with 2 luggages .I don't plan to use kayak in the future and go with Turkish airlines directly

Very bad overall. The comfort level was undeniably uncomfortable. The in-flight entertainment was no good because my screen froze and “wasn’t able to reset”. The staff were rude and non-helpful. Instead of offering me an upgrade for all inconveniences for the ticket, and seat I paid extra for, I was offered a downgraded seat all the way at the back of the aircraft. The flight was delayed for so long, making the experience at the layover airport that much more unpleasant.

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.

Boarding was much delayed, and there was no explanation ( obviously they were waiting for something or someone. ) Passengers were all crowded at the gate with anxiety. On the plane, the crew worked very hard on checking for safety and serving delicious food. They were polite and courteous.

The check in process at Istanbul airport caused my family a great deal of stress and disappointment due to the following factors: 1) WE HAD TO PAY US$330 for check on bags, despite holding Economy tickets that Turkish airlines website clearly states that flights from Istanbul to Miami had a 2 checked bags allowance. 2) Airport staff not only lacked empathy for senior travelers (75 yrs old and 71 yrs old), but were also rude as well. The supervisor at check it offered "if you don't pay for the bags, you can just remain and sleep at the airport for however long you wish. What a terrible way to treat customers !!! 3) We were bumped from agent to agent to agent FIVE times, showing everyone the communication we received telling us we had the 2 bags entitlement. Two elderly people lugging 4 suitcase around and around the Turkish terminal. Again, what a sad way to treat customers !!! 4) We need a case opened to get a refund for the amount we paid. Something is amiss, screams unethical, and sounds unscrupulous......At First , we were told we must pay for 4 bags. All of a sudden, it became 2 bags, and finally all 4 bags were checked on with payments demanded for 2. Why did it vary from agent to agent???? 5) OVERALL, A TERRIBLE AND SUSPICIOUSLLY UNSCRUPULOUS EXPERIENCE FLYING WITH TURKISH AIRLINES. WE ARE TERRIBLY DISAPPOINTED AND SAD THAT OUR VISIT TO A BEAUTIFUL CITY ENDED IN SUCH A HORRIBLE EXPERIENCE

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

Very nice and friendly crew. Boarding system can be improved.

While we were picking up passengers in São Paulo, on our way from Buenos Aires to Istanbul, it was impossible to use the bathrooms for 90 minutes. The crew was largely inattentive with one or two exceptions. They should distribute more water for a flight that long. When I signal that I wanted to have a second glass of wine, my prayers were left unanswered…

they have cancell the flight with no reasons, My parents were in the cold weather in the airport for 24 hours they did not give any hotel and food. I hate Turkish Airline, this is our last time that we ha ve chosen Turkish Airline.

Boarding process is one of the worst i have ever seen. Poor planning and lack of experienced staff is vert apparent. Seat changes till the last minute was an added stress to the process.

This experience was a complete disaster. At first the flight was delayed. No reason given why the flight was delayed. Once transported to the plane (by bus) and waiting on the tarmac, the flight was canceled. The next flight was 6 hours later and that flight was also delayed. Horrible experience and lack of communication from the airline.

There is need to introduce HOME COUNTRY of Departure Meals

Seats were extremely hard and uncomfortable. as well as very narrow even though I paid an extra $230 for upgraded preferred seats. Very disappointed in the downtrend of Lufthansa and United Airlines.

Excellent staff and flight experience. Would rather that I had upgraded to Premium Economy for extra space, but I will know to do it next time.

I arrived late in Frankfurt and I had to catch my flight to Vienna and I was running late because when I was landing the flight to Vienna was boarding. I had to go through immigration and then I had to wait in a long line to take a bus to a terminal where my flight to Vienna was taking off. However, I truly didn't think I would make it. I was literally running through the whole airport and when I stopped to ask at one of the Austrian Airlines gates they were rude because they didn't have the time to support me.

It’s not bad, simply it’s not as it used to be years ago.

The agent, who took my mother to her gate, kept talking with one of her male coworkers and treating my mother like a sack of potatoes. She was ignoring my questions because she was too busy flirting with her male colleague. This was a very unprofessional behavior. We also had to wait for close to half an hour for an agent to arrive.

Delayed take off but I think they waited for passengers.

Check-in was very disappointing. My Seat reservation was no longer honored which I had for several months. Supposedly the monitor was damaged and the seat could not be issued. In the lounge I checked again and the seat had been assigned to someone else so I could not sit next to my wife and no other adjacent seats were available - except right in front of the bathrooms and galley. Very disappointing practices for business class!

Very good flight, only problem is the boarding process where some peoples do not have manners and do not how to fly ( preparing your documents, oversized carry-ons, not understanding or feigning to not understand directives).
