Why Didn't I Think of This?

A new company, Return Key Systems, Inc., has set up self-serve stations at New York's La Guardia, Newark Liberty, Washington Dulles and both Houston airports to mail your prohibited items back to you so that they won't be confiscated by TSA.

It's not cheap, but if you can't live without your daddy's antique Zippo, it might be worth it to spring for the service. Mailing fees range from $6 to $22 per parcel.
