⚖️ 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.

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 Firearms & Ammunition for a Flight

The three unforgivable rules: unloaded, locked hard case, declared at the counter — miss one and your bag gets pulled with police involved. Handguns stay inside the locked case inside your checked bag; ammunition rides best in factory boxes inside the same case. International borders are a different universe — Canada requires the correct licence class and declares at the border, and many countries refuse foreign firearms outright.
