Hartman told a Cook County judge in May that she apologizes to the airport and for "causing problems for them." As part of her plea deal, she can't go to Chicago's O'Hare or Midway airports without a ticket.

This is one of many incidents involving Hartman apparently attempting to sneak aboard a flight without a proper boarding pass, dating back years. In 2015, Hartman was arrested after touching down in Jacksonville, Florida, having stowed away on a flight departing from Minnesota.

The year prior, she was arrested at Los Angeles International Airport after successfully sneaking onto a flight in San Jose, California. She spent nearly six months in jail for violating her probation following that incident, returning to LAX and wandering the airport without a ticket.

Hartman is expected to appear in court on Sunday and faces criminal trespassing charges for the most recent incident at O'Hare.
