I would be interested and grateful to know if anyone has seen this before/can shed some light.

Looking at the seat plan for ZRH-YYZ (AC 879) on June 4th and returning YYZ-ZRH (AC 878) on June 18th both flight seat maps no longer show Row 19 as being an Exit row (they now only show Row 18 whereas before they showed both 18 & 19). On flights I have checked on this route for other dates they still show 18 & 19. Checking on Seat Guru every Air Canada configuration for TATL 763s includes row 19 as an exit row.

Has there been /will there be a change to the seating on the 767s or is this a strange error? We paid extra for preferred seating in Row 19 and want to be sure we'll have the legroom.

Thank you.
