I doubt we'll hear anything about routes until late summer / autumn?
With 3 X based aircraft, if they convert the current schedule to all BHX based units (and potentially increase frequencies) there won't be room for a huge number of new routes. I can foresee AGP, TFS, possibly LPA. FCO and MAD are IMO underserved and I think they could make a go if LYS and BER.
All depends on how happy they are with current routes and frequencies and how much non based flying they plan to/from other bases (which of course is how the whole BHX schedule is currently run!)
