Last week, a woman managed to sneak onto the Delta flight and get to Paris. She had been held in Charles de Gaulle airport until Saturday.

A woman was taken into custody after the stowaway flew aboard a Delta Air Lines flight from New York's JFK International Airport to Paris Charles de Gaulle Airport, the airline said.

Investigators are trying to determine how a woman got past multiple security checkpoints this week at New York’s JFK International Airport and boarded a plane to Paris, apparently hiding in the aircraft’s bathrooms during the flight.
