I can't imagine getting through some places without a paper boarding pass to be scrutinized, annotated, stamped, and scrutinized again by a litany of officials.

I always make sure I have a paper boarding pass, unless I'm on a domestic US itinerary. Saved myself a lot of headache and trouble as a result.
