Looking at that old seat map and seeing reference to smoking/non-smoking sure took me back and not in a good way. So glad that's gone. God, those planes REEKED and I remember a horrible BA flight LAX-LHR that was so smoky towards the lavs in Y there was a stinking gray cloud back there. Coughed and hacked the entire way. Still can't believe it was ever even allowed in the first place.
