From October 16, 2026, new aviation security rules from the Civil Aviation Authority of Thailand (CAAT) change how checked baggage can be inspected at the Thailand’s airports, one of Asia’s busiest travel hubs.

Previously, if security needed to open a suspicious checked bag, staff might have had to locate the passenger first, which could delay baggage handling and departures.
The new regulation by CAAT in October, allows security staff to open a checked bag without the passenger present when screening detects something suspicious.
When can a bag be opened without the passenger?
CAAT has been clear that a bag can only be opened without its owner when screening identifies a suspicious object, prohibited item, explosive or dangerous goods.
The rules also include safeguards for passengers:
Prohibited items found during an inspection can be confiscated and are not returned to the passenger.
CAAT recommends that passengers use Travel Sentry approved locks, which security staff can open with a secure tool. If a bag can't be opened, officers may break the lock with no compensation required.
A Travel Sentry TSA lock allows authorized security staff to unlock, inspect and relock luggage without cutting the lock or damaging the case. For travelers, that means:
Airport security agencies need to protect passengers while keeping airports moving. Thailand's new rules, like China's, recognize that aviation security sometimes requires inspections to happen without the traveler present.
The Travel Sentry standard supports that goal by giving authorized security staff legitimate access for a damage-free inspection. It benefits everyone:
When airports, security agencies and manufacturers work to common global standards, inspections run faster, travelers have a better experience and luggage stays protected throughout the journey.
