Southwest has a warehouse where it collects all the stuff passengers forget, including coats, books, car seats, electronics (they find about five iPods every day), hundreds of cell phones, and the number one forgotten item — sunglasses. The warehouse estimates that 120,000 items come through every year, and only 10 percent of the belongings find their way back to their owners because few passengers call to track down lost items. After a few months, items are donated to the Salvation Army. Check out Southwest's enormous lost and found in the video below.
