Delta Air Lines and United Airlines announce they will ban humanoid robots from passenger aircraft, joining Southwest Airlines, which has already implemented a similar restriction. The move comes amid growing airline concerns about how such devices may affect safety, operations, and compliance with airline policies. The Independent and Yahoo UK News both link the latest bans to an earlier incident involving Southwest, when a passenger brought a robot onto a flight. The reports indicate that airlines are responding by clarifying that humanoid robots are not permitted as carry-on or aboard flights. While details of each carrier’s exact policy and enforcement mechanisms are not fully specified in the provided excerpts, the overall direction is consistent across sources: humanoid robots are being treated as prohibited items on flights. The announcements show a coordinated shift toward restricting non-standard personal devices that could raise safety and security questions in the cabin.
