Rear facing seats cost more and are heavier than the standard airline seat.
I'm not sure why they would cost more
Con. I thought the problem was that pax didn't like to sit facing backwards. Sort of a glass half empty glass half full thing.
WN used to have those club seats and it was a little uncomfortable on climb out if you were facing backwards, though it did give you an opportunity to look up the skirt of the woman sitting opposite
