I saw a BIA director on BBC news today saying BHX handled 50 diverts in 3 days!!
With the south east closed at the moment more are arriving and are having to park on taxiway 'T' and the 80's.
Its all revenue for BHX and also a bit of advertising to southern pax that a superb regional airport exists north of Watford and south of Man.
(Not a dig at EMA btw)
Maybe it'll attract a few southern pax north in future? I still meet people these days from other parts of the UK who didnt even know Birmingham had an airport
