I can't believe there is a fuss over this. The boarding pass holders are old fashioned and out-dated. Very 1960's.
As mentioned here in previous replies, almost no airline outside of the US uses them. They are a waste.
Even when I fly F I have them stick my bag tag to the back of my BP or to the front of my OLCI BP. I put the rest of the BP's in my briefcase or shirt pocket.
The extra folder is not required.
To be honest..I"m surprised they didn't phase them out altogether.
