Heavy fog is causing more flight cancellations at Britain's Heathrow Airport, forcing thousands of travelers to remain stranded for another day.
Weather forecasters say they expect poor conditions across the region to last at least two more days.
British Airways has canceled all of its domestic flights at Heathrow Friday - one of the busiest travel days of the year. The director of ground operations for the airline, Geoff Want, says he will be forced to cancel hundreds more scheduled flights if conditions do not improve.
Thousands of frustrated passengers, their holiday plans spoiled, are camped out in the Heathrow terminals hoping to find a way home or a spare hotel room. The London airport operator (BAA) says it is providing blankets and warm drinks to passengers waiting overnight.
Authorities say travelers to Europe have turned to trains to take them to the continent.
British Airways is offering bus service for about 3,000 people to travel to cities including Manchester, Newcastle and Glasgow, where flights are going ahead as usual.
