Baggage Inspection Requirements for Check-Through Luggage at U.S. Airports
The federal Transportation and Security Administration has instituted new screening procedures at domestic airports throughout the United States to improve security and passenger safety at airports and in planes. This can include the opening of locked check-through baggage without prior notice to the passenger.
Should a bag be selected for inspection, an inspector is required to use whatever means necessary to gain access to the bag. This may include breaking locks to access the contents. If a bag is opened, the TSA official will place a note inside the bag to let the owner know.
If you plan to travel by airplane, we recommend that you familiarize yourself with the procedures that may have been implemented since the last time you traveled.
