I think the Air Arabia version better than Thomson. Is there an ideal? The pax that are not going to pay attention - are always not going to pay attention.
The ones that are going to panic in an evac - are always going to panic.
The ones that are going to revert to first learned behaviour and head for the door they entered by AND take their handluggage? They always will.
One of the most fascinating aspects of the proliferation of mobile phones is how we now get ground-level video of the evac as it happens. We can see just how many pax take their hand luggage and coats and junk with them. We have discussed this in this forum and, most recently, in R&N with the Asiana 777 at SFO in July.
