Turkish Airlines (T�rk Hava Yollari) is Turkey's flag carrier. It was established in 1933 as State Airlines Administration (Devlet Hava Yolari). Its first international destination was Athens, and today boasts one of the largest network of destinations in the world. It calls Istanbul's Atat�rk Airport home. Their callsign is relatively new, replacing Turkair in 2010.
Turkish's livery has been recently updated. The logo is now on a red background and slightly oversized. The wordmark was also updated, while the silver tulip design has been retained.
Here's one from a request, a Bombardier CSeries in Turkish colors. I opted for a wingtip paint treatment that mimics the tail of the aircraft rather than a full circle as seen on their Airbus A330s. The name was taken from THY's BAe 146, although today it has been assigned to one of the airline's Boeing 777-300ERs.
