I'm very tall so the leg room of the seats could have been a little more spacious. Otherwise, everything was excellent

I'm very tall so the leg room of the seats could have been a little more spacious. Otherwise, everything was excellent

The airline could improve its business class seats and privacy in line with its competitors.

The fact that my flight was cancelled and made wait for 14 Fing hours to booka flightto a neighboring country.... never again

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!

Loved the food. No wheelchair was provided in Sofia even though wheelchair assistance was confirmed by Turkish Airlines

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 paid $150 to upgrade to this seat. My exit row seat had ample leg room BUT the collapsable table was broken so my food tray and drinks slid over to my lap, the screen malfunctioned.

As a big guy the seats are way too small for me. Would prefer more comfortable seats on these long haul flights.

Excellent food and service on my international flight. Most notable is the food provided by Turkish even for coach passengers is very good.

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