I have a question possibly related to this thread. I am also traveling SEA to Istanbul this fall, and on my return on 13 OCT on TK203, the flight still shows an A350-900. However, my wife and I who had booked seats together in the center in J, are now randomly reassigned to different rows. The flight is full in J. Does anyone know if it is possible to "correct" this, or what the most effective way is to get this "corrected"? We have a flown on Turkish once previously and based on that experience, we have booked a number of flights in the upcoming 12 months. I'm kind of wondering if this is more the norm than our positive first experience.
