I'm flying TK 1724 TXL-IST this Thursday, which is scheduled to be an A321.
I'm a bit confused to see 3 different seat maps for this aircraft:
TK and Seatmaestro show business class in rows 1-3
Seatgutu shows it in rows 1-4
Seatexpert shows it in rows 1-8
Which of these is correct or do they have all of these configurations? If yes, which one is most likely to be used on this particular flight?
