Why do we travel so much for the holidays? [Video]

Why is holiday travel an ever-increasing undertaking people do year after year? One expert says it’s often connected to tradition. 

This year, AAA says more than 115 million people will be traveling for the holidays, but is there more to be said about the reason so many of us book a flight or load up the car to see our dearest who may not be so near?

“For travelers it really means the busiest airports they’ve ever seen at the end of the year,” says Morgan Dean with AAA.

The company also says not only are flights slightly cheaper than previous years, but drivers will likely spend less on gas, no matter which state you fill up in. 

Whether you’re visiting loved ones or trading in the snow for a sandy beach, the reasons for holiday travel vary.
