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

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

Seats paid for in advance. Seat assignments changed by kayak 3rd party. Seats then changed again by Turkish airlines at the gate. Family seated on opposite sides of the plane yet money taken for seat assignments that were not honored.

Both of our Business Class seats were broken. I'm sure they didn't just break before we boarded but were broken prior. They would not recline. We could sit up straight or lie down, nothing that would allow us to sit back and relax on a 12 hour flight. Totally unacceptable. Very expensive and a waste or money.

Flight was late but loading plane was much easier in Istanbul than athens. Food was so-so and choice was limited. Flight attendants were extremely courteous and helpful; however, it was difficult to get attention during night time service. Overall good experience and the price was right

Food wasn’t good but not their fault as I should have pre selected

We had requested a wheel chair assist for my husband who has Parkinson’s. The first seat we came to we got off the plane was staffed by 3 men-one was on his cell phone, one was sleeping and the fellow we spoke with was rude and seemed as if he didn’t care that we had a plane to catch in one hour. A person with a wheel chair came and took us to the center area for wheelchairs. Here we waited for 20-25 minutes while our flight went to “boarding.” Finally a woman came with a cart and we zipped through the airport.

The desk crew at the LAX crew could do better. A girl named Mahesi was very abrasive and unfriendly. She needs a better customer service uproar.

The local Turkish Airlines staff in Helsinki isn’t not aware of immigration laws of Singapore and wanted to refuse even our first boarding and threatened us with deportation on our own from Singapore. We had the next connection to Istanbul and then Singapore. The airline’s online check in system is requesting the visa to download and doesn’t have any option for 96 hrs VFTF passengers. So in general we made the complaint to the airline, as the boarding experience was awful due to unprofessional staff that doesn’t check or want to check the exceptions in the global system.

Majority of the staff were simply awesome and very very supportive and helpful

I am always amazed with the great service they offer on their regional and international flights
