LONDON (AP) -- Scores of fights have been canceled as snow and ice blanket much of Britain.
London's Heathrow airport says it has canceled about 130 flights, 10 percent of the daily total, compared to 20 percent on Sunday.
Flights have been disrupted since Friday at Heathrow, Europe's busiest airport, which has seen long lines and stranded passengers camping out on its terminal floors.
Heathrow says it has spent millions improving its winter resilience since the airport was virtually shut down by snow for several days in December 2010. But it says low visibility means it must leave bigger gaps between planes, triggering delays and cancelations.
Train services are also disrupted, and hundreds of schools across Britain are closed.
There are also delays and cancelations Monday at airports in Paris, Amsterdam and Frankfurt.
