Ok people...it's simple. We all know that the delivery of this FAs demeanor toward the OP was rude, surly, and uncalled for. Her behavior through-out the flight was uncalled for. Something I'd probably write a letter and complain about. (just don't forget to commend the other two flights)
However, the policy is there in black and white. It's in the American Way Magazine in the Passenger Entertainment section. Has been, even way before 9/11. Yes, BEFORE 9/11!
It's been a rule since the late 70s, early '80s hijackings. (may not have always been printed since then, but it's been around much longer than...wait for it, 9/11!
You make take pictures of family/friends, but never the operation of crews nor aircraft.
