CHICAGO (WPVI) -- A woman with a history of trying to sneak onto airplanes was arrested at O'Hare International Airport.
Marilyn Hartman has been dubbed the "serial stowaway" after nearly a dozen arrests at airports across the country.
Chicago police said in April, Hartman was spotted twice in a restricted area at O'Hare without a ticket. She was taken into custody each time.
Police said she was last arrested on April 23. Hartman was charged with criminal trespassing and appeared in bond court on April 25.
Hartman has been caught seven times at San Francisco International Airport and at least four more times at other airports.
Hartman also claimed to be homeless and was recommended for mental health treatment after earlier arrests.
In February, Hartman allegedly took a flight from Minnesota to Jacksonville, Fla., without a ticket.
She was arrested in Florida after an upscale hotel says she tried to check in under someone else's name. Police say they found Hartman sleeping inside a hotel room.
"She stood around the airport and she thinks somebody just felt sorry for her and just said, 'Come with me,'" Deputy Sheriff Mark Murphy from Nassau County said.
Hartman has now been caught trying to sneak onto flights 11 times since March of 2014.
San Mateo County District Attorney Steve Wagstaffe says Hartman refuses to be reformed.
"We tried everything, including offering our hand to help her out. She doesn't want a hand. I think she just wants to fly," he siad.
Hartman served jail time after successfully stowing away on a flight from San Jose to Los Angeles last August.
