Why wouldn't they have a go at MAN or EMA they seem to do alright out of 2 flights per day to LBA carrying 8000 per month, MAN or EMA would pull more. Also do they have aircraft sitting at BFS vacant most of the day during the winter that could be utilised.
BFS - MAN, BHX, EMA etc, I imagine would carry a good share of business passengers, so to be sustainable would really require early morning and evening returns to BFS. I would see little point of Jet2 using an aircraft to offer once a day, or middle of the day flights to these cities. I doubt Jet2 would prioritise 3 aircraft to take a chance on these routes and allow peak timed flights.
If Jet2 still intend to operate Larnaca from BFS, you think they'd want to release the seats soon, before they miss the peak booking period for the summer. Think its looking unlikely, no???
