Heathrow resumes flights after days of fog

British Airways said it planned to operate a full schedule from London's Heathrow Airport Sunday, after days of severe disruption caused by lingering freezing fog. Heathrow, Europe's busiest airport, said almost 95 percent of flights operated Saturday, after the fog finally lifted. Mark Bullock, Heathrow managing director for airport operator BAA PLC, said, "We can expect to see normal services resume by the end of today." BA, the airport's biggest operator, was using bigger planes on some routes and running buses to domestic destinations to help clear the backlog at Heathrow, where hundreds of flights were canceled this week amid the busy pre-Christmas travel season.
