Denver International Airport was closed Wednesday night due to severe winter conditions, forcing a thousand travellers to stay there overnight, USA Today reports. Airport officials provided several hundred cots and blankets as airport hotels were booked and the main road to downtown Denver was closed.
Most airlines canceled their flights in and out of Denver. It may take several days for things to return to normal. There will also be secondary effects, as flights in other cities are disrupted as the planes meant to operate them are stranded in Denver.
Meanwhile, British Airways canceled all domestic and some European flights to and from London Heathrow today, and has cancelled 100 of their 400 shorthaul flights for tomorrow, Friday, and warned of additional cancellations due to severe fog at the airport. Disruptions at Heathrow and Denver will no doubt cause ripple effects throughout the world during this holiday season.
