Its all very confusing. CWL-ABZ involves the aircraft change but on the way back there doesn't seem to be one...so its technically half a new route, in the next few weeks they may just use the SZ all the way to ABZ i.e. NQY-CWL-NCL-ABZ-NCL-CWL-NQY but that would then screw up the return NCL-CWL making it later in the day. But on Sundays the new CWL-NCL Saab route goes all the way to ABZ involving no aircraft change.
Also it appears that between 24 Dec- 3 Jan T3 are running 3 daily flights. Lets hope 3 daily return in the end.
