The BHX rumours are gaining momentum and are louder then ever, so BHX and LYS.
Maybe with the potential withdrawal of X3 from BHX-CGN for next Summer (unless TUIFly announce more routes later in the year), then Easyjet will do a BHX-CGN route, akin to their successful EMA-CGN route.
Don't think that there will be any problems with the proximity of BHX and EMA for Easyjet...the two airports serve at least 6 big cities between them so plenty of opportunities for passengers (Nottingham, Derby, Leicester, Birmingham, Wolverhampton, Coventry...plus all the large towns in the area).
