At a rough guess, another J41 at NCL would operate either a beefed-up CWL service (unlikely) or a beefed up ABZ service with an early morning northbound to ABZ and late evening southbound. The BA schedule on NCL-ABZ for NCL originating passengers is awful. It could also take over the NCL-ORK for which the DH8 is a bit big, releasing the DH8 for a fourth daily NCL-DUB. Just a thought!
