A series of stowaway incidents involving unticketed passengers trying to board Delta flights from Seattle to Hawaii have raised significant security concerns. During the holiday season, several attempts were made, including one on Christmas Eve when a suspect managed to sneak onto a flight without a ticket before security personnel apprehended them. TSA is currently investigating these recurring breaches, as multiple stowaways have been caught over the past month, highlighting potential lapses in airport security protocols. These events have prompted Delta to issue apologies and raise awareness of the safety issues associated with unauthorized access to flights.
