If I remember rightly the Bergamo flights ceased around the time Bergamo Manchester started. Ryanair don't really rate Newcastle airport as a worthwhile proposition. Shame really. Even in these times of economic gloom there would be money to be made. Daily would be unviable but three times a week would probably hit the spot. The same could be said for Madrid, Frankfurt Hahn and possibly Valencia.
We can live in hope but don't hold your breath.
