Hartman has been arrested several times on trespassing charges for trying to sneak past security and get onto planes at O'Hare and Midway International Airport to stow away.

Back in July, she tried to board a plane at Midway without a ticket less than 24 hours after being released from jail.

She successfully snuck onto a plane in San Jose in 2014 and was arrested when it landed in Los Angeles. And just days after her release, she was arrested again at LAX.

Recently, Hartman was confined to a locked mental health facility. But earlier this month, a judge allowed her to transfer to another facility, which allowed her more freedom.

She has had several odd confrontations with police at airports across the country and has spent at least 145 days in jail.

As part of Hartman's mental health probation, she was ordered to stay away from Chicago's airports.
