A Delta Air Lines flight nearly left Seattle for Honolulu with a stowaway on Christmas Eve, a month after another person successfully took a Delta flight from New York to Paris without a boarding pass.

Customers on a Delta Air Lines flight from Seattle to Honolulu were delayed by several hours after someone snuck on board. The Atlanta-based airline released a statement to ABC News on Thursday afternoon that confirmed an “unticketed passenger” made their way onto the Christmas Eve flight and had to be removed from the plane.
