⚖️ 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.

How to Pack Engine Parts & Purged Engines for a Flight

Purge is a process, not a promise: run the tank dry, drain the carburetor, ventilate until there is no odor, and cap all lines — a single whiff of gasoline vapors lets the airline refuse the part at the counter. Brand-new parts that never saw fuel travel easiest, boxed and receipted. Canada is stricter than the US here: CATSA bans fuel-containing equipment outright, so on transborder routes “purged” may still mean “refused.”
