Actually it could be very possible
They could use HAJ based aircraft to fly the MAN & BHX routes
They also fly into Hannover for Brussels airlines so maybe aircraft and crew can be utilised for that
There is opportunities to fly to other UK airport and the fact that EZY or FR are not about helps with the low cost airline front
Looking at therouteshop.com there is plenty of routes that have been researched and a Dash would work well on them
