Entertainment was good. Flight was delayed, nearly missed my connecting flight. The gate was changed on several occasions. My luggage did not arrive on time and had to leave without it.

Entertainment was good. Flight was delayed, nearly missed my connecting flight. The gate was changed on several occasions. My luggage did not arrive on time and had to leave without it.

The flight attendants were generally rude. I requested a blanket for my toddler and didn’t receive the blanket until about about 3 hours later into the flight after multiple asks for different crew!

this was a short flight in business class. I had problem in the Istambul airport - the lounge for Turkish Airlines was too far and we never were able to reach it

The flight from Istanbul to Karachi was an old plane in which the seats don’t even come close to lying flat. It was uncomfortable - may as well have been economy, and a far cry from Qatar Airways that I’m used to. The food was mediocre and entertainment couldn’t even be used because there was zero privacy like in a normal business class, so it would feel as though everyone is watching the movie with you - which is awkward. I had to put my food tray out as a leg stopper to get into some sort of comfortable position to curl up and sleep, which is ridiculous. Unacceptable given the ticket still has a business class price tag.

I already checked in online and provided with a window seat by default which was OK with me. When I printed the pass at the airport, I found that the seat number was different (aisle but in same row). By that time, all window seats were taken up, I am surprised that TK can unilaterally change seats after completed online checkin.

So boarding is a little slow when you fly 787 but on the 777 the business class had its own entrance. The entertainment can be a little bit more up to date Other than that it was a great experience food and service was great

They changed the return flight to the next day and it interrupted the plans we had in our connecting city.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

The food and drinks were below the normal standard we expect from Turkish Airlines. On a 4 hour flight we received 1 drinks service and 1 food service, the latter was a cheese omlete, which is well below what we have received in the past, such a shame we always recommend this airline..

I really enjoyed the food, only bad part on one of my flights my screen was a bit buggy but it wasn't a big deal it was one of their older planes so I understand that happens
