"As an exercise, I suggest you fly into BVA and CDG and go by public transport to the centre of Paris (St Michel) and see which is fastest, I think I can guarantee you that BVA is fastest and the easiest to do"
I think a statement like that reveals you've never actually done both.
Interesting to see Ryanair expanding out of the likes of Gatwick. Perhaps a sign that there is only a finite market prepared to fly to minor airports, miles from anywhere. Too many new 800's chasing too few customers from all accounts.
