American Airlines Carriage & Security Policy
49 CFR § 1540.111 — IATA & Aviation Standards
Carriage of lock 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 lock under strict hazard criteria. Items with sharp edges, heavy weight, or weaponized potential will trigger an automatic secondary bag inspection. If lock 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.

At the security line, remove lock from your main bag only if requested by officers or if it contains large electronics/liquids.
