You have something like 45s-90s to get off an airplane and sprint for your life, I've heard. (If anyone has a source, post it). Keep your phone, passport, and your keys in your pockets, and your shoes on your feet during taxi, takeoff, landing. Do not wear flip flops on airlines (you can't run in them) and they provide zero fire protection if you have to run across flaming ground. Everything is replaceable.

I hope it never comes to it, but I would absolutely "move" a person towards the exit, if needed, if they stopped to get their bag, only to save the lives of everyone else.
