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

One of the best flights I have been on in a while. Food was excellent. The chair-back screens in economy were A+. The crew was friendly and helpful.

Turkish Airlines overbooked the flight and they did not allow me to board the flight even though I had the proper boarding pass and was at the gate on time. Simply unacceptable.

A fairly standard 2/2 configuration. Boeing 787-9 is modern but the amenities chosen by Turkish for their seats are slightly limited - no in-seat charging, for example. Otherwise, a good flight.

Very old plane on the Istanbul to Bangkok flight, had an emergency exit isle row, no where to put anything, on a plus point loads of leg room. Food was the best I have had in 39 years of flying.

Old aircraft, very very low business class standards, no privacy between the seats, horrible old TVs, tiny bathrooms.

The flight was delayed both legs of the journey. The seats were cramped.

The boarding was confusing everyone asking each other the same question is this going to Dxb? The seat was awful felt like your sitting on a bench. I would not recommend it to anyone.

Food quality and the overall service of the staff and significantly decreased. The flight was delayed at the Istanbul airport and the passengers were kept onboard for more than 3 hours. The staff didn’t kept the passengers informed and everyone was upset.

Communication between the captain/crew and the passengers needs to be improved.

Food and service are good. Bathroom was lack of lotions and cleaning. That should be improved.

Food & service very good next I will pick up again

Chinese flight attendants didn't speak english well. They didn't care enough to remember that I (east asian who isn't Chinese) wasn't Chinese and spoke English. Announcement in english on board was poor and I find it very difficult to understand what was announced. Also, a cabin bag allows only 5kg!

Everything was not satisfactory - the flight was delayed, staffs were ok but they didn't speak English well. I am from east Asia (not Chinese) and they didn't care enough to remember that I wasn't Chinese but persistently spoke chinese to me. The flight announcement in english wasn't clear to understand.

I wish I had been able to choose a vegetarian meal. Crew friendly and helpful. Seat was ok. All quite efficient and pleasant. Would recommend for inner China travel for sure.

The flight is not bad, but the Business Lounge is not big enough for the quantity of people they accept and there is a limited options for food and beverages.

It was simply bad and on top of that my luggage hasn't been delivered until now. They can't even localize it which is just unacceptable when they are supposed to scan the bar code they put when we check in

We bought premium Economy, thinking it would be more comfortable, but the seat is so narrow ,that my legs and feet are swollen , I can't wear shoes !
