Passengers will eventually be able to read e-books, play games,
and watch videos on their devices during all phases of flight,
with very limited exceptions. Electronic items, books and
magazines, must be held or put in the seat back pocket during the
actual takeoff and landing roll. Cell phones should be in airplane
mode or with cellular service disabled — i.e., no signal bars
displayed — and cannot be used for voice communications based on
FCC regulations that prohibit any airborne calls using cell phones.
