CHICAGO -- The woman accused of trying to sneak onto planes in Chicago appeared in court today on trespassing charges.
Marilyn Hartman is known as the "serial stowaway."
Chicago police arrested her at Midway airport on Sunday night.
TSA agents said she was hanging around a checkpoint without a ticket.
She also was arrested last month at O'Hare airport for being in a restricted area without a ticket.
Hartman has been arrested several times over the past year for similar incidents at airports in California and Florida.
Back in August, she managed to board an airplane without a ticket in San Jose, and flew to Los Angeles.
A Cook County judge ordered her to be held at Cook County Jail, and undergo a psychiatric exam.
Hartman's attorney does not expect her to post bail, so she will wait in Cook County Jail until her next court appearance in June.
