Excellent service. Friendly and attentive flight attendants, can lay back in business class and be pretty comfortable, and delicious food. Flight on time departing and arriving.

Excellent service. Friendly and attentive flight attendants, can lay back in business class and be pretty comfortable, and delicious food. Flight on time departing and arriving.

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

They are absolutely impossible to get hold of. A death in the family caused us to delay our departure. They are impossible to get through to and after waiting 41/2 hours I was told they would not consider helping us. They cancelled our return flight and have not reimbursed anything. I strongly urge readers to consider a different airline.

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.

Not good. I was supposed to be in Mint but got in economy class

I had issue with my boarding pass. When I arrived in London Gatwick Airport. My e-ticket wasn't scanning and had to do a lot of back and forth with Air Transit I order to board my flight, which I almost missed as a result of this.

My experience with Turkish Airlines was good. I didn’t get the meal I ordered. So I didn’t have anything to eat which was disappointing.

Bad confort, bad seat take advantage of the political conflict to double the price

The best airline for international travel in terms of value you get in business class (service/cost)

Boarded via bus instead of the air bridge Had to wait 10mins in the bus at the tarmac before we were allow to go up

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

I had a good comfortable seat. There was nearly an hour delay. There was an accident with the champagne, but I was well compensated. These things happen sometimes.

Bulkhead seats should not be an extra charge. They are extremely uncomfortable. And we missed our connecting flight due to slow luggage retreaval.

When I bought my ticket , I bought it for a premium flex and I paid more money to get comfortable seat , but I get a basic economy seat, I need a refund for the ticket Thank you Rabeh Afli

The crew and especially Patrick were amazing. Very helpful, kind and accommodating. I’d be happy to fly with this crew for all my Europe trips!

I had a sprained ankle and had to go down the stairs to the bus and then up the stairs to the plane. Food / dinner served cold

A bit more space? Not practical, I know. I felt squished in but part of that could have been the man sitting next to me.

good entertainment package but rather small seats for business class

They don’t give information on why a flight is delayed in a timely manner. Very frustrating.

The entertainment screens need to be updated. Very difficult to navigate through with old equipment.
