The Wednesday before Thanksgiving is the busiest travel day of the year, and the American Automobile Association is predicting even more people will be on the highways this year.
The AAA estimates that 42.5 million people will travel over the holiday, a four percent increase from last year and the highest number since the start of the recession.
More people traveling this weekend could mean more delays -- and the crowds aren't the only reason.
With rough weather forecast for the east and west coasts, travelers may run into monster storms that could have a ripple effect across the nation.
"We are already seeing delays. We're seeing cancellations coming into the New York Airport. Even though Los Angeles is fine right now -- what might happen is the planes aren't going to make it there and so every airport around the country is affected," explained Melissa Klurman, Travelocity contributing editor.
Despite gas prices up 50 cents a gallon more than last year, an estimated 90 percent of Americans will be traveling by automobile. And many of them will be driving right into the bad weather.
"Definitely practice patience, and just look out for your fellow traveler," said Troy Green, a spokesman for AAA.
Despite the weather, AAA expects a 4 percent increase in travel this holiday season. Why are more Americans hitting the road this year, even with a struggling economy?
CBN News spoke with AAA public relations representative Cyndie Brough about this. Watch her comments below.
Keep a watchful eye on the roads and in airports. The Transportation Security Administration advises if you see something unusual, say something to a security officer.
Airport security lines could run more quickly this year, thanks to some new rules.
The TSA said the new system is more forgiving for children aged 12 and under, now considered low security risks.
"It helps reduce pat downs -- yet not eliminate pat downs -- of passengers 12 and under," TSA spokesperson Lisa Farbstein said.
The agency has also created security shortcuts for frequent flyers and airplane crews, using information already in the system to identify them.
In addition, the TSA has installed new software in the airport body scan machines. The new program displays more of a cookie cutter outline of a person rather than the graphic body images the old software revealed.
