Electronic devices: cannot be brought into the cabin of the plane on international flights to the United States.
Patdowns: Required, for now.
Items on laps: No blankets, bags, suitcases, purses, etc on your lap during the last hour of flight. Your hands must be visible at all times.
No potty breaks: Passengers cannot get out of their seats for the last hour of a flight.
I feel safer all ready. Wonder what the penalty is for pissing on the floor?
