Thailand's Civil Aviation Authority (CAAT) clarified its checked baggage inspection rules on October 25, 2026, after several complaints about bags being opened. The rules have been in force since October 16, 2026. Staff can only open a bag when X-ray screening flags something suspicious, and only authorised airport personnel can do it. The search has to be recorded on camera, and a Notice of Baggage Inspection has to be left inside the bag. Here is what that means if you are flying out of Koh Lanta's nearest airports or anywhere else in Thailand.
What the rules say
Bags can only be opened if X-ray screening flags a suspicious item. Routine opening of every bag is not allowed. Only authorised airport personnel may do it.
The procedure works like this:
- The flagged bag goes to a designated inspection area.
- The inspection must be recorded on camera.
- Officers must put a Notice of Baggage Inspection inside the bag.
Opening luggage outside designated areas, outside the procedure, or by unauthorised staff could be a legal offence.
The items most commonly detected are power banks and battery-powered electronic devices. These are a fire and short-circuit risk in the cargo hold.
The four complaint cases
Four cases were shared on social media, and CAAT looked into each one:
1. International flight departing Thailand: CCTV showed it was not an inspection by airport screening officers under the new rules. 2. International flight departing Thailand: same finding. 3. Flight arriving in Thailand from overseas: screening happened at the origin airport under that country's rules, so Thailand's measures did not apply. 4. Domestic flight: officers legitimately opened the bag after detecting a battery-powered electrical device. The passenger had no TSA-approved lock, so officers cut the zip. The inspection notice was placed inside.
Who is responsible if something goes wrong
Airlines remain responsible for checked luggage through the journey. If your bag is damaged or items go missing, contact your airline. It will investigate with the relevant agencies.
CAAT's advice for packing
- Check your airline's prohibited items list and baggage restrictions before packing.
- Power banks are not allowed in checked luggage. Other battery devices may be restricted depending on type and airline.
- Photograph the contents before closing the bag, and the bag's exterior at check-in, as evidence.
- Don't pack valuables in checked luggage.
CAAT says it will keep monitoring implementation and informing the public.
What this means for travellers
- Put power banks and spare batteries in your carry-on, never in checked bags.
- Use a TSA-approved lock. Otherwise a flagged bag may be cut open.
- Look for the inspection notice inside your bag. Its presence means a legitimate search.
- Take photos of the packed contents and the bag exterior at check-in.
- Keep valuables in your carry-on.
- For damage or missing items, go to your airline first.
- Searches on flights arriving in Thailand are governed by the departure country's rules, not Thailand's new rules.
