Should you lock your luggage when traveling? Why it's a weighty matter

As travelers embark on their summer trips this year, experts are weighing in on whether people should take the extra precaution of protecting their luggage by locking it up.

"Over the years, travel security has tightened for good reason," said Page.

"People are not only concerned that their bags will go missing, but also that the bags are not secure or even securely handled," she added.

Gary Leff, a Texas-based travel industry expert and author of the blog "View From the Wing," told Fox News Digital he wouldn't pack anything worth locking in checked bags.

The Transportation Security Administration (TSA) estimates that approximately 90,000 to 100,000 items are left behind at checkpoints each month. 

"There isn't much downside to locking your bag - until, of course, you lose the key or forget the combination," said Leff.
