Travel for this year's Thanksgiving holiday in the United States is expected to reach levels not seen since the September 11 terrorist attacks three years ago.
A leading U.S. travel association, the American Automobile Association, predicts that some 37 million Americans will venture at least 80 kilometers from home.
It says about 4.6 million travelers will go by plane and endure the long security procedures put in place after the terror attacks carried out by 19 al-Qaida skyjackers.
Another 30 million Americans are expected to travel by car, leading to long traffic jams around major cities.
