If a suitcase opens during transit, the outcome depends on where it happens in the baggage handling system. If it occurs on the tarmac or in the aircraft hold, ground handlers are instructed to gather the contents, place them back inside, and secure the bag with heavy-duty plastic wrap or "damage tape" provided by the airline. If the bag is severely compromised, the airline may place the entire suitcase inside a large clear plastic bin or bag. Upon arrival, you will likely find a notice inside the bag or a sticker on the exterior explaining that the luggage was found open. If items are missing or damaged, you must file a Property Irregularity Report (PIR) at the airport's baggage claim office before leaving. To prevent this, travelers are encouraged to use TSA-approved locks or luggage straps. Modern "hard-shell" cases with latch systems are generally more secure than those with zippers, which can be "popped" easily with a ballpoint pen. In 2026, many airlines are testing AI-monitored conveyor belts that can flag "open" bags before they reach the aircraft.
