Pilots wear lanyards primarily for security and practical accessibility. The most important item on that lanyard is their Airport Identification Badge (SIDA badge) or Company ID. In 2026, security protocols at international airports require that flight crews have their credentials visible at all times when in secure areas, on the tarmac, or in the cockpit. Since pilot uniforms often have epaulets but may not always have convenient chest pockets that allow for quick "tapping" at electronic readers, a lanyard provides a centralized place to keep the ID reachable. Additionally, many pilots attach their electronic flight bag (EFB) keys, small flashlights for pre-flight inspections, or "creds" that allow them to bypass standard passenger security lines via "Known Crewmember" programs. High-visibility or company-branded lanyards also serve as a secondary visual cue for ground staff and security personnel to identify authorized personnel from a distance. For safety, most pilot lanyards are "break-away" style to ensure they don't become a strangulation hazard if caught in cockpit equipment.
