LHR
NCL has had 5 out of 6 flights from LHR cancelled today.(aprox 80%)
LBA has had 2 out of 4 (50%)
MAN has had 6 out of 12 (50%)
ABZ has had 3 out of 8 (aprox 38%)
EDI has has 4 out of 12 (aprox 33%)
GLA has had 2 out of 12 (aprox 16%)
That is correct as at 17 45 hrs and may change as the day progresses but it certainly shows where the priorities lie. ( hope I have done the sums correctly )
