I'm on Flight 797, PHL-LAX, right now. To my left in Row 22, a man stood up, put on a tefillin, and began to pray. Considering that there were two recent incidents where the flight crew overreacted to such a practice (including a US flight being diverted), I was on alert to watch for any reactions.

It was nice to see that none of the passengers nor any for the FA's interfered with the man in any way who was praying. No "bomb scare" this time. ^

Of course, likely contributing to the understanding is that this flight is a connection from another flight with the same number: US797, TLV-PHL.
