Servisair actually terminated the contract with FlyBE last September - they we're too much hassle, draining too many resources and paying the same price for the contract that they did before the extra BAConnect flights.
I can understand why it's useful to use shares, especially with the CDG going on to BHD, just it could be a little easier to use!
I think BE should look at Brussels, French regional routes, MAN, DUB, HAM, DUS, FRA as well as winter favourites for them such as GVA and SZG.
