As a frequent pax, I wish that more airlines would behave in a way that supports safety.
Instead we get overlong videos (I'm looking at you, BA) that seem to be designed to entertain and chug and crew who stand by placidly as people overtalk the briefings.
The best airline that I fly, in this respect, is Ryanair. Very short and to the point briefing and crew often prepared to ask pax to be quiet.
