BHD flight deck will have to operate the flight as they are LCY ops trained and the aircraft is technically a BHD aircraft, the one that was an operational spare. (Any other base that operates to LCY the trained flight deck can also technically operate also). However it seems the same set up arrangement as the ABZ-LCY when it was originally launched.
I can see the crew night stop in CWL and operate CWL-LCY-BHD or
CWL-LCY-CWL-BHD and then the aircraft does a few rotations from BHD and then does BHD-CWL-LCY-CWL that was the crew only stop away from base for 1 night and the change of crew is done in BHD on an operational flight.
