vfrpilotpb and others have raised interesting points, especially how likely it is that an aircraft would be evacuated quickly.
It seems that the airline companies themselves will only take notice if another manchester accident takes place.
I cannot fathom the mentality that says, "if we increase exits/room at exit rows tickets will cost more" I mean, jesus christ - just do it. What would it mean, an extra 10-20 quid to give everyone on an aircraft a fighting chance to get off. If it is true that the space on wing exit rows is to be decreased, then I believe TV comapnies have every right (and my blessing) to be as sensationalist as possible. The stupidity behind such a move would be truly stunning.
As I've said before, it will be interesting watching a full charter config A380 evacuate.
As other have said, good to see Mr whicker again - a real travel journalist. Class.
