I've never been in an emergency so I don't know how I'd react, but I recall seeing video last year when that Delta flight in Toronto flipped over of people with their cellphones and suitcases out. Now it looks like there's a push to lock overhead bins if an education campaign doesn't work.
An Iata survey of air passengers recently found that only 61 per cent
of people correctly answered that they should leave all personal items
and exit the aircraft.Of the 33 per cent who said that they had seen reports of people
taking their baggage during an evacuation, 22 per cent also indicated
that they would likely to do the same.
