At the largest terminal at New York’s John F. Kennedy International Airport on one of the busiest travel days of the year, security lapses enabled an unticketed passenger to board a plane to Paris in a shocking breach that one aviation expert said should serve as a “wake-up call” for the airline industry.

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.

A fifty-something Russian woman who this week made headlines after sneaking onto a Paris-bound Delta flight from New York’s John F. Kennedy airport remains detained in the City of Love after causing a scene such that was she deplaned from her flight back to the United States.
