Dawdler,
Reading around these forums many a handling agent employee, or similar, or Reggie Spotter(s) are making statements that they're little ol' regional airport should always be increasing business etc. and much of this is ridiculous, you'll have to excuse me if I point this out from time to time, but whether I point it out or not it's not going to change reality, whatever I may say isn't going to change anything.
Hence I am not determined about anything, above on this page a CVT fanatic states that 'easy' do not use BHX, well guess what ..... Easyjet do use BHX!
CVT may have a future once a new passenger terminal building may be built, just when might that happen?
And LPL/MAN, GLA/EDI etc. aren't 10 (ish) minutes down the road/railway from each other as CVT/BHX are!
