However, Lufthansa, one of the leaders of Star Alliance, is an major competitor of Turkish Airlines.
Besides, Turkish Airlines is also in talks with Skyteam.
However, oneworld was not mentioned.
I was wondering that why Turkish Airlines isn't thinking of joining oneworld. American Airlines is its partner on codesharing flights and frequent flyer programme, MILES&Miles.
As an oneworld fan, I strongly recommend Turkish Airlines to join oneworld!!
