It seem airport operator BAA has realized that Global warming has really dumped on them the last two years and rather than be caught with their pants down again, they 3x increased their equipment and staff ready to clear snow.
From BBC: Heathrow airport triples snow clearance fleet
Heathrow airport has tripled the number of snow clearance vehicles to tackle severe winter weather.
Operator BAA also has three times as many staff ready to clear snow compared with last year.
Thousands of passengers were left stranded at the airport as 4,000 flights were cancelled over five days for heavy snow before Christmas.
But BAA said it now has 185 snow clearance vehicles and has 468 staff per shift, compared to 117 last year.
The operator said it has invested £32.4m so far to tackle severe weather.
BAA had been criticised following last year’s disruptions and a report accused the operator of a breakdown in communication and lack of “preparedness” for the bad weather.
After the publication of the Winter Resilience Enquiry Report, BAA promised to invest £50m to avoid facing disruptions on a similar scale.
Announcing its “winter resilience programme”, the airports operator said it has introduced a new “reservist” role whereby up to 950 staff will be deployed to the terminals to help passengers during disruption.
