I would guess that the ZB routes will be about the same, as the B757 are now in charter config only.
I know that all the fleets operate the odd ZB during the summer including A300 and B757s all without the extra leg room seats, but the ZB fleet is the A320/321s.
Only time will tell, but at the moment NC & ND will be around for a year or two yet.
The ACE flight might have been a MON flight and not due to operate just yet.
