Air Canada mainline seem to be taking over the rouge route at MAN. AC1930 from 2nd Oct 2015 is no longer showing 'operated by rouge', and the loaded seat maps show AC mainline B767 seat maps.
If you try to process a reservation, it shows J class zeroed out.
If you select W class instead and then seat availability, it offers you rows 1 - 4 as 2x2x2 seating, which of course is not the mainline config for J, which is 1x1x1 herringbone.
