I flew on 3 flights with Turkish Airlines last November and I couldn't fault them. In fact, I think they were better than British Airways, who I also took 2 connecting flights with for the same holiday. The crew and pilots were very professional, the aircraft clean and comfortable, the food delicious, and my flight arrived early into Heathrow coming back, in fact, I had more hassle getting from terminal 2 to terminal 5 for my connecting flight home than at any other point.
As Jaya has already mentioned, I don't take any notice of airline reviews, and Turkish Airlines have won numerous recent awards as the best European Airline, so that says it all.
I can thoroughly recommend this holiday, please see the holiday reviews section, and if you need any further information don't hesitate to ask.

Caroline
