I'm not sure that BHX were probably even aware that Wizz were looking to start flights from the Midlands given the minimal interest (until VERY recently) of the BHX Marketing teams interest in lo-co - and thats only cos they have to be now, given that their hallowed BA/BACON are about to vacate the premises. Sorry to be cynical but I just don't think BHX is anywhere near its potential route development wise, there have been some major opportunities missed. If BHX were approached by Wizz and couldn't offer them a deal based on the fact that they have the future potential to develop an East European network so badly needed at BHX (look at the routes they offer from LPL, BFS and DSA) then that really says it all
Good luck to them at CVT!
