The seats were extremely small. Boarding was not communicated correctly. It wasn’t a pleasant trip.

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.

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

Very small and cramped aisles and seats. Food was poor but the fresh hot roll and hummus was good. No cans of soda given but they had small bottles of water. Crew was nice and pleasant and kept bathroom clean.

Small seat space for 13 hours flight, they charged for baggage , very bad quality of food,

With a 4 hour delay its was a very basic flight which was just bearable. We were offered food vouchers for the delay and then they didnt work, so that was annoying. Also poor communication about the delay which got pushed out 3 times.

It was my first time flying with Turkish Airlines, but I found the staff—from the airport to the cabin crew—to be somewhat dismissive and overly direct. This experience left me feeling discouraged about even considering a visit to Turkey in the future.

Very poor! It was too hot! It smelled. The food was nasty. The bathroom sink to wash hand was barely working. The tray table was broken. Everything was just wrong!

Everything was great except the meat served was tough and overcooked!

It was a quick flight, and it was fine. The only thing was my seats wouldn’t recline because I was in the last row. It was a 1am flight so that made it hard to sleep. But otherwise it was fine.
