I'm likely flying in J from IST to ORD later this month. The seat map for the flight shows a 7 row business class cabin, which I understand is one of the 359s originally ordered by Aeroflot, but never operated by them. Do all 359 flights show the 7 row business cabin seat map in advance? In other words, does TK show both the 7 and 8 row maps based on what aircraft they expect will operate a flight, or do they just so the 7 row map believing that it is easier to handle seating issues going from a smaller to larger cabin versus the other way?

Thanks!
