Tis the season for holiday travel

CHICAGO (NBC) -- It's Thanksgiving week and for many of us, 'tis the season to travel.

Over the next few days, airports and highways will be packed with millions getting away for the holiday.

One of the busiest places will be O'Hare Airport in Chicago.

The airport is the crossroads for millions of travelers.

Chicago’s O’Hare is relatively calm right now, but it will be the busiest airport in the nation this week.

The holiday travel week is now officially underway.

Whether it's over the river, through the woods to grandmas, others just getting away - in all AAA said more than 43 million will take a trip over Thanksgiving.

"90% of those traveling will do so by automobile,” said Robert Darbelnet, AAA President.

Most will be getting out on the highway.

"It's sort of, between TSA scanning and sharing a plane with a crying baby, I’d rather drive!" said Arnell Cordero.

For those who do fly - more than 3million passengers will pull luggage through airports.

Transportation security agents have a few tips on how to keep the lines moving.

"Jellies, jams and preserves - anything like that, even cranberry sauce for thanksgiving being around the corner. These objects can go through in your checked luggage but they cannot go through the check point in your carry-on luggage,” said one TSA agent.

No matter how or where they're going, most who travel this week make the trip for the same reasons.

“The top activities, as usual, will be spending time with family and friends, dining and shopping,” said Darbelnet.

To make sure you have a fun and safe trip experts say make sure you plan ahead and prepare for crowds both at the airport or on the road.
