Heavy traffic as holiday travelers hit the air, roads

New figures from AAA show 92 million Americans expect to travel 50 miles or more through January 2 and 90-percent say they'll be traveling by car.

The Transportation Security Agency is now offering a special hotline for travelers with medical needs.

The TSA Cares program helps people who may require extra support getting through security. Passengers can call before they get to the airport and have customer service managers coordinate checkpoint support. Their items will still be screened. TSA recommends passengers call 72 hours ahead of travel.
