It remains unclear how the person managed to bypass security at JFK Airport and board the Delta Airlines flight to Paris.

Delta Air Lines will not fly the Russian woman who stowed away on a flight to Paris last week back to New York, a Paris airport official told CNN. She was due to leave France on a flight at 2:30 p.m.

French officials tell ABC News that the woman who allegedly snuck onto a Delta Airlines international flight is a Russian national who did not have valid travel documents to enter the country.
