On Christmas Eve, an unticketed passenger gained access to a Delta Air Lines flight from Seattle to Honolulu, prompting the aircraft to return to the gate. The individual was apprehended after hiding in a restroom following the discovery. Delta faced scrutiny over security protocols after this incident, which follows another stowaway case just weeks prior. The TSA is conducting a review, emphasizing that standard screening procedures allowed the individual to bypass check-in requirements. As safety and security remain top priorities, Delta apologized to affected customers for the delay.
