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 accused of sneaking onto a Delta Air Lines flight from New York City to Paris last week was on her way back to New York City's John F. Kennedy International Airport Wednesday.

The woman boarded Delta Flight No. 264 from John F. Kennedy International Airport to Paris Charles de Gaulle Airport, CBS News learned. She was discovered while the plane was in midair and was taken into custody in Paris.
