Snow wreaks havoc on British travellers

Snow and wintry weather are still wreaking havoc on travellers in Britain, with flights cancelled, roads covered in ice and rail travel disrupted.

With temperatures dropping overnight as low as minus 11.6C, hundreds of schools were closed Monday. Europe's largest airport, Heathrow, warned that some flights would be cancelled as it cleared the backlog of flights delayed by Sunday's snowfall.

Heathrow asked travellers to check with their airlines. In the world of interconnected air travel, any extended disruption quickly leaves planes and flight crews out of position, knocking them out of rotation for their next assignments.

National Rail said poor weather conditions are affecting travel across England and Wales.
