Travel forecasts point to packed airports and roads.

After lifting its shutdown-era flight restrictions on commercial airlines last week, the Federal Aviation Administration now says it's preparing for its busiest Thanksgiving week in 15 years, with more than 360,000 flights scheduled to take off in the U.S. between Monday and next Tuesday. That’s more than 17.8 million people who will be screened by the Transportation Security Administration.

AAA projects that 6 million people will be traveling by air between Tuesday and the following Monday.

Whether driving is your top choice or backup plan, AAA spokesperson Aixa Diaz suggests first checking your tires, car battery and fluids, then hitting the road as early as possible to avoid traffic.
