My impression with EJ is that their PAs are FAR too wordy - far too long and often patronising. The overall impression in the cabin is of being talked to death with PAs and that just makes people ignore them. If ever there was a case of less is more it is here.
And why do the flight crew have to tell pax about the weather on every PA? Surely once on the welcome aboard and at ToD is more than enough? Not much imagination goes into those, (and like the pax the FO's never listen to what the Capt said on the welcome aboard hence, I suspect, the duplication) but then there is no training whatsoever for pilot pas, just a rather poor and inimaginative guide in some obscure corner of a website somewhere. PAs are, imho, one of EJ's weakest points.
