Traveling today? You’re not alone. According to Triple A, a record 112.5 million Americans are traveling for the holidays this year -- 4.4 percent more than last year, and the most since AAA started tracking holiday travel in 2001. 102.1 million people (the most ever) will be traveling by car, 6.7 million are flying (the most in 15 years) and 3.7 million will travel by trains, buses and cruise ships. And today – December 20th – is the worst day to hit the road, according to travel analytics service INRIX, because both commuters and travelers will be crowding the roadways. According to their data, today, drivers in Atlanta, New York City, Boston and Houston will have travel times more than three times that of a normal trip. (Market Watch)
