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 stowaway who boarded a flight in New York and made it all the way to Paris on Tuesday was removed from her return flight to the U.S. after she caused a disturbance, a source said Sunday. A source with knowledge of the situation said the woman "created a disturbance" as the Delta flight was set to return to New York.
