It still bothers me to think that they are leaving it up to FA's to determine if someone has a Note 7.
While I respect and love the AC FA's (many of them I would book flights with just to fly with even if at different times) they are not tech's and trying to figure out if someone has a note 7 or not, when looking at a plane full of 450 pax, I do not beleive can be done with accuracy.
