A woman known for trying to sneak onto planes without a ticket has been arrested at two Chicago airports.

Chicago police spokeswoman Janel Sedevic says 63-year-old Marilyn Hartman was arrested April 24 for loitering in a restricted area at O'Hare. She was charged with misdemeanor criminal trespassing on state land and released.

She was arrested again on Sunday at Midway and charged with the same offense in addition to violating her bail bond. She's being held in the Cook County jail.

It isn't immediately clear if she has an attorney who can comment on her behalf.

Hartman has succeeded in getting on a flight at least once without a ticket. In August she flew from San Jose to Los Angeles.

She has previously said she's mentally ill and homeless.
