Major airports in New York, North Carolina and Las Vegas are rejecting a proposed ad campaign from PETA that makes light of the new full-body scanners being used at airport security checkpoints.

The ads from People for the Ethical Treatment of Animals features a scan of a curvaceous woman in lacy underwear with the message: "Be Proud of Your Body Scan: Go Vegan."

Major airports in Las Vegas, Charlotte, N.C., and New York City refused to display the ads designed to entice holiday travelers waiting in security lines.

Officials with McCarran International Airport in Las Vegas say its policy prohibits political ads.

PETA Vice President Dan Matthews says the ads were meant to be humorous. He says PETA hasn't taken a political position on airport security measures.
