More poor info today !
I know there were strong winds at LHR - but some of this was absorbed by slot delays (WR delay code today).
However - 'expect 10-15' total delay at BNN. Various curt responses from controllers when asked 'was this 10-15 holding in addition to slowing up' - reply was a terse ' no, total delay - as I said !'
Anyway we were given 10-15 mins which became an EAT of 22 mins and then this wasn't honoured either - missed by about 4 mins!
I suppose I should routinely carry 30 mins then no nasty surprises ?
