This is certainly no laughing matter.
When the most frequent and non-frequent travelers forget their name or what their personal carry-on bags look like, tags are a wonderful way to remind them of their name and which airline they fly most frequently.
I have made it a point to ask Mrs. EnPremiere to attach these to my wheelchair when I hit the ripe age of 100-105-ish in case I find myself wandering off to an airport somewhere (or spaceport if we've sorted that out by then). Hopefully by then I'll be life-time Exp if that ever becomes a status which will help me avoid the worst of the seats on the future Boeing 937-MAX.
