Operated: 2003 (May)
Flew from: One flight only... ever. From Miami to Cancun for "Nude Week".
Gimmick: A gimmick indeed, this one-day airline was the PR stunt of a Houston-based travel agency that (still) provides "clothing-optional vacations and cruises worldwide". It amounted to a single flight, during which 100 or so charter passengers -- most of whom nobody wants to see in the buff -- disrobed.

Isn't cold up there?

Yeah---if you're outside of the plane. ;)

Inside, not so much.
