New restrictions will be enforced starting Jan. 1 to protect air travelers who bring their laptops on board.

Travelers will be required to place extra computer batteries inside Ziploc-style bags before boarding an airplane. Federal authorities say the lithium batteries used in laptops and video cameras can get hot and have the potential to cause a fire if contact is made with other metals.

Transportation Security Administration baggage handlers at Westchester County Airport say they already have a large supply of bags available, even though the law won't go into effect until Tuesday.

Some travelers who spoke with News 12 Connecticut said they're concerned the new policy could cause some security screening congestion problems, especially since they had never heard of the new restriction.
