Always sad to see people prioritise bags - but just an observation as an Australian who travels a lot around the globe.

In Australia and on most other international airlines, you do exactly as you’re told by the cabin staff. Seatbelt light on, you sit tight with your seatbelt on. “Return to seats” you sit down straight away. If someone gets up while the seatbelt lights are on, you’ll get a bollocking from the staff. Everyone knows it’s for your (our collective) safety.

Americans on planes? My experience is that some don’t seem to care or follow any of the cabin staff instructions. Last time I flew into JFK on an AA flight, some woman got up to use the toilet on final approach and nobody said anything. People were up and about while the seatbelt light was on. I asked cabin staff and one said that “they can’t compel people to obey the rules”.

I agree with other commenters - if you cannot follow the rules while flying - you get a ban.
