A Chicago woman accused of getting on a plane at O’Hare Airport without a ticket says she was trying to go to a Jay-Z concert in Los Angeles. Prosecutors told a Cook County judge yesterday that Yaazmina Payton told them she avoided security checkpoints Sunday morning and boarded an American Airlines flight so she could see the Grammy Award-winning rapper. The 23-year-old defendant was charged with felony criminal trespass. A judge ordered Payton released on 500-dollars bail, but barred her from the airport. Meanwhile, TSA officials are conducting an investigation that could take 90 days to complete.
