I'm sceptical of any claim - usually made by those caught out, not performing or the press - that this is the worst weather since 1910, 1210 or 'since records were kept'. Fact is fact: the UK's short-termism - manifested by managers in industry, government and the military - costs the country in the long-term (or even sooner). It boils down to crap management; telling that LGW is doing better than LHR (I did some research into some aspects of ground handling at several airports in the UK earlier this year: LGW was by far the most cooperative and open of all those I visited).
Still, the boss at BAA will get a bonus this year; one trusts it will be for financial performance rather than customer service.
