A serial stowaway who has snuck onto flights for the past 20 years has revealed how she gets past security.
Marilyn Hartman, 69, has bagged more than 30 trips without a ticket, starting with a journey to Copenhagen in 2002.
The pensioner was recently re-arrested after allegedly trying to escape home custody by jetting out of O'Hare Airport, Chicago.
The arrest comes just days she gave her first ever interview to local news station CBS2 - and spoke about her travel secrets.
Marilyn is known throughout the US to the Transport Security Administration (TSA).

But she said: "I got by them, this is the thing that is so crazy, by following someone they would be carrying like a blue bag.
"And the next thing I know, I get into the TSA line and TSA lets me through, and they think I'm with the guy with the blue bag.
"The thing I've got to tell you. I have never been able to board a plane by myself. I was always let through.
"I mean I was able to go through the security line without a boarding pass."
Despite her claims, court records and reports show that Marilyn was repeatedly caught carrying another passenger's boarding pass.
She has also been known to arrive in another country without documentation to get through border checks, and stopped.

Marilyn's initial trip to Denmark was followed by flights to cities like London and Paris, visiting the former as recently as 2018.
This was also the last time she successfully boarded a plane, according to reports.
Marilyn has also jetted to locations across the US, like Los Angeles and Seattle - and has even travelled as far as Maui.
But she has been in trouble with the authorities for years, with several arrests on her record.
She is still facing charges of burglary, criminal trespassing and probation violation after being caught at O'Hare Airport in 2019.
The OAP was arrested for the first time in 2014, when her name was added to a trespass list and a judge warned her to stop.
But she did not listen - and is now facing possible jail time after breaching probation.

Marilyn previously spoke about her mental health issues, and said part of her need to catch flights was borne out of depression.
She said: "I'm bipolar. And this is something I’ve rejected for years.
"When I took the plane ride, I wasn't happy. I wasn't: 'Oh, I’m going here or there' - I was actually in a depressed state of mind."
Her infamy was aired in an audio recording of a TSA agent, obtained by CBS2.
They said: "There's been a Marilyn sighting over here."
But of the TSA agents, she said: "It was not my intention to make their jobs more difficult."
