The TSA and CBP, both agencies of the DHS, are taking a "good, hard look" at combining voluntary vetting programs that allow travelers to get through checkpoints quickly.

2. Airlines are Banning Smart Luggage That Lacks Removable Batteries

Many airlines are beginning to ban smart luggage that doesn't have a removable battery, reports Fortune. Most smart luggage are powered by lithium-ion batteries, the same type found in the Samsung Galaxy Note 7, which have been known to catch fire on flights. Airline officials say they want to get the word out early about the smart luggage ban, in order to prevent passengers from making such purchases during the holiday season. For travelers with smart luggage containing removable batteries, they will be asked to remove those batteries before checking their bags. Batteries in carry-on luggage can remain installed as long as the passenger is able to remove them. To read more, click here.
