I am traveling on TK8 from IAD to IST on April 25th along with my fiance. Having noted from several sources that Row 37 has extra space and legroom (due to the transition from 4 --> 3 across) I called Turkish and reserved both aisles in that row. Seatguru and various web postings all note that this is row 37, however when I make a dummy booking on the TK website, the seat map shows that the transition row is labeled 36, not 37. The TK agent I spoke to on the phone said that she had placed us in the transition row, but the TK map shows us booked one row behind. So, which is correct? And is it worth taking the gamble that the middle seat in this row remains unoccupied, or should we just bite the bullet and grab one of the remaining 2-seaters before they fill?

Thanks in advance!
