Promos Given Out During South By Southwest Blamed for Security Delays at Austin Airport

Swag given to attendees of the South By Southwest festival set off airport security alarms Wednesday, leaving passengers complaining of long delays as they tried to head home.

Jason Zielinski, an Austin-Bergstrom International Airport spokesman, said that a particular type of ink on some item was thought to have made it difficult to scan baggage with X-ray machines, forcing officials to individually screen bags.

Zielinski said he didn't know the exact cause of the problem, but said he'd heard it blamed on festival promotional items, including stickers, a free magazine "or any combination of things."
