You can launder the voucher by purchasing the cheapest fully refundable you can find for as far in the future as possible. Flight 656 ATL-PNS Jan 2 2005 one way FC is $167.10. I think you have one year after an unused ticket to use it, meaning you'd have until basically the end of 2005 to travel.

You'd need to pay an extra $67.10 to buy the ticket, and you'd also be wouldn't be able to use the ticket later on for any web tickets, only over the phone or in person (but that's no different from any ticket now).
