From a pax point of view it is increasingly unacceptable the extent to which short-haul services, particularly the domestic trunks, get significant cancellations (as on the day in question) whenever Heathrow gets into LVPs, which are surely to be expected quite regularly.
All that investment in Autoland over the years to enable operations to be maintained in poor weather is now wasted on these routes because when such conditions happen the airport has allowed such saturation of its runway capacity that the domestics end up getting cancelled anyway to meet the lower runway rates. And yet LHR higher management continue to peddle the public line that they are not at runway capacity yet.
