Insiders that have access to your luggage or even bystanders in the terminal can take a look at your luggage tag, take a digital picture of the luggage tag and forward the information to another criminal crew that can size up your house to make sure nobody is home, and commit a burglary. If the criminals are organized, they could break into your house before you’ve even taken off on your plane ride.
Travelers are advised to use their business address or a UPS Store mailbox address, if they have one.
