- zoomablemind 4y agoI vaguely remember that PA messages are heard in headphones, so the PA signal is being patched through at some point. It's not clear how the "seats" bus is isolated. I assume it's a bus, so that seats are addressable. The seats should at least be able to send the "need attendant" signal. I hope a qualified technical analysis already pointed a few possible vectors for this. The question is in remediation and, well, identification of the perp(s). Either way, at this moment the story seems to act more as an attracting magnet than repelling for the airline. Back during summer, it certainly was another level of annoying and disturbing.
