I've seen numerous helpful tips all across this site so I will add mine:

This is the same reason that I pack an extra belt or two in an easy-to-reach section of my carry-on baggage. It can act as a flail and subsequently be used to secure any dirtbag hijackers to their chairs, assuming they survive the beating administered by angry passengers.

And a sharpened new #2 pencil held between the 3rd and 4th fingers with the eraser against the palm - inserted under the jaw with an upward thrust will make it thru the nasal cavity and enter the brain. Other trajectories are effective as well.
