⚖️ 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.

⚠️ 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 Gasoline & Fuel for a Flight

There is no small-quantity exception: unlike lighter fluid’s tiny DOT allowance on some cargo rules, gasoline in passenger bags is banned outright in the US — any container, any size. The bottle that held it matters too: a jerry can reeking of fuel vapor can be refused as contaminated equipment. Fly with a brand-new, never-filled container and buy fuel at the destination.
