BANGKOK, Thailand – Thailand’s aviation regulator has introduced new procedures allowing airport security staff to open checked luggage without notifying passengers in advance when X-ray screening detects suspicious objects or items that may threaten aviation safety.
The measures, effective October 16, 2026, are not intended to permit random searches of every passenger’s suitcase. Inspections must be based on security concerns identified during screening.
According to the announcement, staff must document the inspection, preserve evidence throughout the process and notify the luggage owner afterwards. Procedures are also in place for reviewing inspections and handling complaints if baggage is damaged.
The Civil Aviation Authority of Thailand (CAAT) said the new procedures follow international aviation security practices and are intended to improve screening efficiency while reducing delays caused by having to locate passengers to open suspicious baggage.
Passengers are advised to use internationally recognized locks, such as TSA-approved locks, which can be opened with special security tools, and to check prohibited-item rules before departure. If baggage is damaged or passengers have concerns about an inspection, they can complain through their airline or directly to CAAT via its complaints portal.
