The Aerolopa seat map for the Air India Boeing 787-9 shows 8 rows, with the last row consisting of seats 8A and 8K. Seats 8A and 8K can also be seen in a photo in a FlyerTalk trip report with the title "Vistara 787-9 Dreamliner business class - Review" (I cannot post links yet).
By contrast, the seat map on the Air India website and in their app only shows 7 rows (see screenshot below), without seats 8A and 8K.
Is there another configuration of the B789 with only 7 rows in the business cabin? Is the seat map in the Air India app erroneous?
Update, 7 December 2025: Air India has corrected the seat map for the B789. Seats 8A and 8K are now shown and available for selection.
