The only [my bold] true statistic is MAN % of total UK Pax, and you will see from below 2011 is the same as 1981 !
That really is a sweeping statement. There are a lot more airports around now who have increased their capacity , so obviously MAN's share as a percentage will decrease. The 'true' statistic will be MAN's profitability.
Can't we stop all this willy-waving on PPrune? It used to be MAN-LPL, but now it seems to be MAN-BHX as well.
