Am booked in CW on BA25 16 September and BA26 30 September (High J 744)

Just noticed on Expertflyer that the rear CW cabin (Rows 17 to 20) appears
to be totally devoid of seat bookings.

Is this a sign of the times I wonder, turning a High J 744 into a Low J 744 by closing one of the 3 cabins off due to low demand. Presumably this also means more flexibility for BA as a Low J aircraft could also be put on the flight at short notice. Less seat choice for me though as the flights are rapidly filling up on the UD!!
