Thailand has introduced stricter airport security measures for liquids, gels, and aerosols (LGAs) effective April 22, 2025. The new rules limit container sizes to 100ml and require all LGAs to fit into a single transparent, resealable one-litre bag. Larger quantities must be packed in checked luggage. Exemptions apply for essential medicines, baby food, and duty-free purchases, with enhanced screening for safety and efficiency at checkpoints.
