Virgin Airlines Advertising Meets Mae West

This email  from Virgin via my friend Tim hearkens back to the Virginia Slims advertising campaign, which suggested that women like it just a little bit longer. Just a "silly millimeter" in fact. Men, however, think bigger. The subject line, is a reference to the 1933 film, She Done Him Wrong, when Mae West turns to Cary Grant and asks him, "Is that a gun in your pocket or are you glad to see me?"
So just who do you think Virgin is targeting here?
