Not jumping to any fast conclusions, trying to imply anything, but too much collecting of less useful stuff, nowadays borders to, or falls within the "hoarding" entity. As I've done that myself, saving not tickets/boarding passes, but hotel key cards, I made them usable for one night, when co-arranging a rather large party. At the entrance, everybody was invited to take a key card, which was the place card for the different dinner tables, as they were named after big hotel chains. Those unused were deposited in plastic recycling container.

As per the question in OP?
I join the shred-it team.
