A few pennies left in a screening bin won’t usually send someone sprinting back to an airport’s security checkpoint—and now the TSA is cashing in on that tendency. The agency has been using some $675,841 in unclaimed spare change to expand its Pre-Check Program. What’s more, it's predicted that this year will reap even more in lost change: upwards of $700,000 in 2015, or roughly 140,000 $5 airport water bottles.
So which travelers are the most prone to ditch the dough? New York’s John F. Kennedy International Airport contributed $42,550 to the grand total.
