For the first time, newly released security footage shows the moment an alleged stowaway sneaked onto a transatlantic flight just before last Thanksgiving in a stunning breach of security. Svetlana Dali is accused of boarding an overnight Delta flight from John F. Kennedy International Airport in New York City on Nov. 26 and traveling to Paris-Charles de Gaulle Airport in France without having a ticket. Dali can be seen in a video obtained by ABC News walking up to gate B38 at Terminal 4 while other passengers have their boarding passes and passports checked.
