for the second time disappointed with TK, they like JAT = joke about time

No customer service. Non educated staff members with no will to support or service the passenger.

Working stuffs in flight are very welcoming,but boarding stuffs are the Ghana airport don't know their job.

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.

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

Aircraft you use on this route are always old and poor! This drives the entire experience down

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.

It wasn't good. I didn’t understand. They changed 320 dollars for 2 luggage. My ticket was regular and I paid almost 1200.00 dollars. Why they did charge? I want my money back.. thanks Yılmaz polat

All was fine , but air conditioning was not working on board properly so was very hot

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

I didn’t have food and they don’t include entertainment. Not much leg room at all. Staff were great.

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

Business class was nothing more than Economy with middle seat empty. Uncomfortable seat and leg room. A mom behind me had a 18 month/2 yr old on her lap, who had his feet on my back all the time- while middle seat remained empty. Pretty much not worth the fare. Very disappointed.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

charging port did not work, no entertainment system. Other than that the flight was good and safe.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

When Stephen arrived with our wheel chairs - we were in excellent hands! He was such great help with getting our rental car and then reporting our missing luggage. When you are exhausted from traveling for too many hours, he was just what we needed to navigate everything! Give that guy a raise!

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

Gate information deliberately delayed to only one hour B4 flight, lack of info finding gate.
