London:snow,delays,Eurostar delayed by 'fluffy'snow

Last Friday after a 5 hour delay at Tunis arirport my British Airways flight to London finallly took off;no announcments made or compensation given, just the continous message 'en retard' on the departures board.
However,no problems at Heathrow as there seemed to be only snow in the south which caused Gatwick airport to close for 2 hours and cancel lots of flights.Perhaps I should have flown to Heathrow!

The Eurostar trains were delayed with many irate passengers stranded in Paris and London a bizarre explanation of 'fluffy snow' was given for the breakdown of the trains.
The weekend in London was quite warm and sunny but Monday the sky grey and cloudy with a mixture and snow hitting the streets of London causing traffic to almost come to a grinding halt.
