Airports across Britain suffered disruption on Monday. Flights to and from London airports were being affected. “If you are due to travel today we advise that you check the status of your flight with your airline before traveling to the airport as there may be some disruption to flights,” London’s Heathrow Airport said. Sunday’s disruption at Heathrow came on the last day of the school half-term holidays for much of the country. Except the extreme fog density situation, as now, fog is already a common fact for London. Charles Dickens first conjured the image of foggy Victorian London in fiction.
