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

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

Everything about that day was great I was happy with how things went as a first time traveling with the airline thank you for all that you’ve doing by taking us there to our various destinations thanks.

Entertainment was good. Flight was delayed, nearly missed my connecting flight. The gate was changed on several occasions. My luggage did not arrive on time and had to leave without it.

The flight attendants were generally rude. I requested a blanket for my toddler and didn’t receive the blanket until about about 3 hours later into the flight after multiple asks for different crew!

this was a short flight in business class. I had problem in the Istambul airport - the lounge for Turkish Airlines was too far and we never were able to reach it

The flight from Istanbul to Karachi was an old plane in which the seats don’t even come close to lying flat. It was uncomfortable - may as well have been economy, and a far cry from Qatar Airways that I’m used to. The food was mediocre and entertainment couldn’t even be used because there was zero privacy like in a normal business class, so it would feel as though everyone is watching the movie with you - which is awkward. I had to put my food tray out as a leg stopper to get into some sort of comfortable position to curl up and sleep, which is ridiculous. Unacceptable given the ticket still has a business class price tag.

I already checked in online and provided with a window seat by default which was OK with me. When I printed the pass at the airport, I found that the seat number was different (aisle but in same row). By that time, all window seats were taken up, I am surprised that TK can unilaterally change seats after completed online checkin.

They changed the return flight to the next day and it interrupted the plans we had in our connecting city.
