⚖️ Why This Rule Exists: Cabin Security, Blade Restrictions & Sterile Area Integrity

Sharp blades, pointed metal tools, strike implements, and sporting equipment (bats, clubs, martial arts tools) are strictly prohibited from the passenger aircraft cabin to prevent potential weapons or coercion in the sterile area. They must be safely sheathed and packed in checked luggage.

Decision Threshold: Blades and strike tools must be transported in checked luggage only.

🔍 Security Checkpoint & X-Ray Screening Advice

Pack all knives, multi-tools with blades, scissors over 4 inches (10 cm), and heavy tools in checked luggage. Ensure sharp edges are securely wrapped to protect baggage handling personnel.

⚠️ Common Traveler Mistake to Avoid

The Mistake: Leaving a pocket knife or multi-tool on a keychain or in a daily backpack pocket when heading to the airport.

How to Avoid It: Check all backpack pockets and keychains before leaving home to avoid surrender at the checkpoint.

How to Pack Bleach for a Flight

Bleach never survives screening math: it is a corrosive, not a toiletry, so the 100 ml liquids exemption does not apply. Do not decant it into travel bottles — mislabeled corrosives leak and ruin the hold, and officers treat unlabeled liquids as suspect. Buy a small bottle at your destination instead, or pack bleach-free detergent sheets, which fly unrestricted in either bag.
