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

According to TSA, the stowaway flier bypassed two identity verification and boarding status stations at John F. Kennedy International Airport.

A stowaway who allegedly boarded a Delta Air Lines flight without a boarding pass wasn’t discovered until shortly before the plane touched down in Paris. The unidentified woman was caught onboard the fully booked Delta flight 264 on Wednesday (27 November) when a flight attendant became suspicious of the passenger’s long stints in the aircraft bathrooms.
