Authorities in the United States have reviewed airport security footage as they continue to investigate how a woman sneaked on board a Delta Air Lines flight from New York to Paris without a ticket last Tuesday –– one of the busiest travel days of the year.

Delta Air Lines recently witnessed a stowaway situation on their flight from New York to Paris. The incident took place last week when a woman flew to France without a ticket while spending most of the traveling time in the washroom. When she was set to return to the US, she caused a disturbance at the airport.
