The Federal Aviation Administration is telling US airlines to get tougher about a message that’s often ignored during cabin emergencies by ensuring the passengers know they must leave their carry-on bags behind. The agency said it has documented several evacuations where passengers’ attempts to remove luggage delayed exits and compromised safety equipment. In this case, the agency cites operational data and safety reports showing that passenger non-compliance is a recurring and potentially deadly problem. Risks include blocked aisles, trip-and-fall hazards, evacuations that take longer than survival conditions allow, and higher injury and fatality rates, the FAA said. Airlines are expected to respond by updating preflight safety demonstrations, revising safety cards, and possibly adopting standardized phrasing.
