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.

The woman who flew as a stowaway from New York to Paris has been identified as 57-year-old Svetlana Dali. She remains in France after allegedly causing a disturbance on a return flight to the US.
