You may well be right but who, five years ago, would have forecast the rapid growth we have seen in the past half decade?
I did preface my final paragraph with the word 'if' and the comment from the CWL managing director also pointed out that, "Such Master Plans are based upon policy-making, rather than firm development proposals, since they make fixed assumptions. However, they form a substantial opportunity for dialogue and we embraced this opportunity with enthusiasm."
Even if the airports in the south west corner of Britain don't reach the predicted pax figures it is still likely that new opportunities will arise for pax in that area.
I never travel from the London airports any more. I always go from a local airport even if I have to transit via somewhere like AMS to go further afield.
Having taken my son to LHR at the weekend I see no reason to change this habit.
