A woman who flew as a stowaway on a Delta Air Lines flight from New York to Paris earlier this week remains in France after causing a disturbance on a flight scheduled to take her back to the United States Saturday,

A passenger went through security screening but avoided identity and boarding pass checks before flying out of the United States, a T.S.A. representative said.

Officials say the woman is a Russian national who did not have a ticket when she boarded the plane at John F. Kennedy International Airport.
