Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

It was disapointing during the wait in Cancun. It took several hours to clean and they told us during that time we could not stand, use the bathroom, have service etc.

I was asked window seat on check in in Dar-es-Salaam. The person on the deck told me "yes, no problem", but gave me 10e and 25b seats! Better just to say "no"

Turkish Airlines inflight crew was very good, however the ground crew was not very helpful. I had booked a wheelchair for my mother from Islamabad and she received the service there, but then there was no chair on arrival at Istanbul. The wheelchair crew said that they declined to take any person without a reservation and declined to help with the arrangement of a reservation. I had to use the airport buggy system to transport my mother who has limited mobility and needs a wheelchair. It was very disappointing and I hope they can provide manual wheelchair access to the public by a need basis, as sometimes there is a mix up or technical fault in the completion of the process, as it was in our case. Also, there can be an emergent need for passengers if they have illnesses like hypertension or diabetes. My mother has both hypertension and diabetes and has residual weakness after a stroke, therefore, she needs assistance. I hope that this text will be taken seriously and the administration makes the necessary changes. Thanks.

The crew is not focused on the guests but on their task!! No extra service. No business class amenities provided. A crew is not friendly if you ask for something extra, like tea. It takes 30 minutes, and you have to go them 3 reminders. Lack of friendliness, less but more of let me finish and go back to their group and Talk. Like a passenger is in on there way. So get your I gave you food just shut up

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.

Typically good service onboard but baggage delay in airport was significant

Turkish Airlines was great. My new layover was over 18 hours due to inclement weather back home in Washington DC and the airlines provided me with a hotel room and dinner voucher during my layover

Bad sitting every flight not good experience with food either

My, Syed Zawar Hussein Shirazi frequently flyer membership number was not included on my boarding pass from O’Hare to Istanbul despite my reminder to the attendant at check in. Further she forgot to give me my boarding pass form Istanbul to Lahore and she needs to improve her customer service, please 🙏

Food is terrible, service is not good. Staff were not personable and rushed food service.

The onboarding was extremely confusing. Had to climb the stairs to plan from tarmac with carryon bags in hand. No apologies for inconvenience. Overall not quite pleasant experience.

Boarding /lounge :Chaotic boarding , business /first class had a dedicated line but it was upto to the passenger to figure out and use those lines .Oasis lounge is clean but tiny so it felt over crowded . Neither the food nor amenities felt business/first class . Cabin and tech : 2-2-2 configuration needs to go . Leg space is cramped , headsets didn’t work . WIFI does exist or didn’t work on the entire 20 hour journey . Food and crew : Preordered “Hindu Non vegetarian” meal , crew was clueless , they didn’t even bother to ask if they weren’t sure what that meant . Served mediocre vegetarian food though menu had chicken /lamb options . In short , worst business class experience of all the airlines I flew to date . Not sure if there is one area they compete in let alone excel … avoid if you can .

Food was not available in the middle of the trip that is 13 hours

Everything was good and no points to complain. Food is always a tricky concept. Sometimes you like it and sometimes you don’t. Food was redundant from Kuwait City to NY-JFK.

Beautiful Flight took off on time and everything was good

Next time im going to use Kuwait air lines, hopefully

Comfortable seats. Be aware there is no alcohol on this airline.

Seats were comfortable. Be aware there is no alcohol on this airline.

Every thing was very food except the meal. It was a sandwich of something like a beef kebab. It was really bad in terms of hardness as well as taste. We were a family of 7 persons non of us could eat it his sandwich. Cake was good.

Screens should work, Seating need to be comfortable, Luggage management was worse. Took 2 hours to get my luggage

Flight was delayed 110 mins.. Crew on Ground or in Air had no regrets.. No apologies... Very poor boarding process... Awful food and beverage choice.

Flight was delayed and due to this we almost miss the connection flight

The flight was delayed by 3 hours, causing me to miss my connecting international flight. I then had to wait in the airport 18 hours for the next flight. The reason for the delay was a computer issue, not something outside of their control like weather. To add insult to injury, instead of trying to expedite the flight to make up for lost time, they ran a carry-on baggage check to verify every bag onboard belonged to someone on the plane, which took another 20 minutes.

झूठा है इंडिगो फ्लाइट में मील दिया नहीं जब शिकायत किया तो बोला आपको मिल चुका है

It took a lot of time to declare that the flight gonna be cancelled ☹️ very disappointed.

They denied my meal which was included in ticket and also damaged my bag completely and broke the wheel and still not accepting their fault

As budget airline everything was good. Except that - boarding process can be more organised. Then if entertainment systems are not operational. Its better to keep them switch off.

Flight cancelled after 4+ hour delay. Indigo created a nightmare scenario and showed the most callus attitude towards the passengers I will refer to them was IndiNoGo!

Very nice and pleasant. Boarding was quick and the crew were responsive
