"Gate lice" is a pejorative slang term used in the aviation industry and frequent flyer communities to describe passengers who crowd the boarding area and hover directly in front of the gate long before their specific boarding group or zone has been called. This behavior often leads to significant congestion, making it difficult for those in priority groups (like first-class or elite status flyers) to reach the boarding pass scanner. The primary motivation for "gate lice" is usually the competition for overhead bin space; as airlines have increased baggage fees, more passengers bring larger carry-on bags, and being first in your group ensures your bag stays with you rather than being gate-checked. In late 2024 and throughout 2026, major airlines like American Airlines have begun implementing automated technology that triggers an audible alert or rejects a boarding pass if a passenger attempts to scan into a group earlier than their assigned one, effectively combatting this phenomenon.
