⚖️ 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.

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 Lighter Fluid for a Flight

Symmetry worth remembering: the lighter may fly (one fueled, non-torch lighter in your pocket), but its food may not — every drop and canister of lighter fluid is banned in both bags by both countries. If you are packing a Zippo as a gift, ship the fluid separately or buy it at the destination; premium fluid costs less than the checked-bag argument at the checkpoint.
