The in flight entertainment was very good but unfortunately I feel they could have been more attentive to the customer. This is saw on all my Turkish airlines flights , besides dinner service you never really saw the attendants.

The in flight entertainment was very good but unfortunately I feel they could have been more attentive to the customer. This is saw on all my Turkish airlines flights , besides dinner service you never really saw the attendants.

The seat 7A had no padding. I needed to sit on the provided pillow.

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.

The WiFi setup on the plane is needlessly cumbersome. Simplify the interface and login.

Same as before boarding process and lack of crew experience in the process

The trip had a 19 hour layover, and no hotel accommodation was provided. This a shame for an airline to do to their customers. I will not only stop flying with Turkish Airlines, I will make sure anyone I know avoid Turkish Airlines because of how lousy their layover system is.

Their weakness is in boarding. Business class rarely boards first and there are no announcements explaining delays, so customers are always left waiting and wondering why boarding has paused.

For me it was a good experience… thank you Turkish Airlines

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.

Absolutely horrible experience. It's an overnight flight for over 5 hours and business class does not have beds!!!!! I had a slightly bigger than economy class seat that was broken and not even reclining correctly. I should get a refund for this flight as they changed the aircraft to a small one and that is not what I paid the business class price for!

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 !
