American Airlines Carriage & Security Policy
49 CFR § 1540.111 — IATA & Aviation Standards
Carriage of knife is governed by TSA security directives under 49 CFR § 1540.111 regarding passenger screening and baggage security. Security rules distinguish sharply between accessible passenger cabin space (where items that could serve as weapons or hazards are prohibited) and cargo hold baggage (where items are safely stowed during flight).
Security Checkpoint Screening Procedure
Security officers evaluate knife under strict hazard criteria. Items with sharp edges, heavy weight, or weaponized potential will trigger an automatic secondary bag inspection. If knife is prohibited in carry-on bags, attempting to pass through the checkpoint with it will lead to mandatory confiscation. Ensure tools under 7 inches, sports equipment, or camping gear are clearly accessible in your bag if permitted, or securely wrapped inside checked luggage.
Step-by-Step Packing Guide for American Airlines Passengers
Confirm that knife is fully permitted in checked hold baggage and does not contain prohibited HAZMAT components or uninstalled lithium batteries.
Wrap knife in bubble wrap, heavy clothing, or a padded protective pouch to shield it from baggage handling turbulence.
Pack the item deep inside the center of your suitcase, buffered by clothing on all sides rather than pressed against outer luggage walls.
Secure your suitcase with a TSA-approved combination lock so airport screening agents can inspect and relock the bag without damage.
Verify your packed bag does not exceed your airline's checked weight threshold (typically 50 lbs / 23 kg) to prevent excess fees at check-in.
