⚖️ 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 Flares for a Flight

Boaters and drivers get caught here: genuine pyrotechnic flares cannot fly in passenger baggage under US rules at all, and even Canada’s carrier-approval path is nearly always refused. The clean workaround is a Coast-Guard-accepted LED electronic flare — same distress function, zero pyrotechnics, both bags legal. Buy chemical flares at the destination and dispose of them locally before flying home.
