The holiday travel rush has begun, and some say it will be the busiest Thanksgiving week in 13 years.

AAA says more than 54 million people will travel 50 miles or more from home, a 4.8 increase over last year - and the most since 2005.

The TSA is also gearing up for its busiest Thanksgiving at the airport.

Travel times start to increase today, so in the most congested cities, it could take four times longer to maneuver a normal trip, including in New York.

The best days to travel is Thanksgiving Day, Friday or Saturday.       

The worst day to travel will be Wednesday.
