It's a fact of life that other outside a scenario know how to run things better.. Perhaps you could suggest ways in which Heathrow could improve in this respect. I don't suppose that they were sitting there with their minds in neutral and their thumbs up their backsides, or do you think that is the case?. I am sure they were doing their best, but being disrupted is not something the Brits tolerate very easily.
