Developments: 2. Travelers are advised on specific regulations regarding carry-on and checked baggage to avoid security delays. For carry-on items, certain exceptions to the 100ml liquid rule apply to essential medicines and baby food, provided travelers can present medical documentation or allow staff to verify the contents. Additionally, power banks, vapes, and devices containing lithium batteries must be kept in carry-on luggage and are prohibited in checked bags. Regarding checked luggage, certain items can trigger manual inspections or scanner errors. Loose objects like ribbons or bows attached to handles can interfere with automatic scanners, potentially causing bags to miss connecting flights due to the time required for manual checks. Old luggage stickers with damaged barcodes can also cause recognition issues. Furthermore, dense food items such as Spanish nougat (turrón) or marzipan (mazapán) may trigger alarms because their density can be mistaken for explosives by security scanners. ## Timeline ### 2026-08-16: Airport security guidelines for carry-on and checked baggage Travelers are advised on airport security rules, including exceptions for medicines and baby food in carry-ons, and warnings against packing power banks or dense foods like marzipan in checked luggage. 2 sources. https://clstr.news/cluster/airport-security-guidelines-for-carry-on-and-checked-baggage ### 2026-08-07: U.S. Airport Security Guidelines and Marijuana Travel Restrictions TSA recommends PreCheck and careful packing for smoother security, while federal law still bans recreational marijuana and allows limited medical marijuana with unclear TSA instructions; airlines also prohibit. 3 sources. https://clstr.news/cluster/us-airport-security-guidelines-and-marijuana-travel-restrictions --- Cite as: Airport security and baggage regulations.
