The number of Americans expected to travel over the Thanksgiving holiday, the highest ever recorded, according to AAA. About 73 million will hit the road, a figure that could climb if travelers swap flights for car trips after recent FAA-related delays and cancellations during the government shutdown. With restrictions at the 40 largest U.S. airports now lifted, the Department of Transportation says air travel should stabilize before the holiday rush. Still, only about 6 million people are expected to fly this year, with Nov. 30 projected to be the busiest day at airports nationwide.
