You can't make a post like that and not elaborate...

I like a paper boarding pass, if someone handed it to me as I walk towards security. I don't like a paper boarding pass for every MANY other reasons (got to go and print it and the kiosk is slow as [expletive] and I'm sure as heck not waiting in line.

I don't like paper boarding passes that you print at home either as it doesn't fit easily into my rear back pocket of my dress pants, versus a BP printed at the airport fits nicely in (cue: Up In The Air movie. I slot the BP in my pants like Clooney does )
