A 63-year-old woman known for her repeated attempts to sneak onto planes told authorities that she slipped onto a flight from Minneapolis-St. Paul International Airport to Jacksonville, Fla., where she checked into a resort under someone else’s name, officials there said Tuesday.

Marilyn J. Hartman is accused of felony fraud and misdemeanor trespassing in connection with the alleged deception at the Omni Amelia Island Plantation Resort. She remains jailed in lieu of $50,000 bail.

The Transportation Security Administration (TSA) is investigating, said agency spokeswoman Lorie Dankers, who declined to speak further about the incident.

No one with law enforcement, the TSA or Delta Air Lines, the dominant carrier out of the Twin Cities, has confirmed Hartman’s account of how she traveled to Jacksonville.

Hartman took a shuttle from the airport Sunday to the resort, where she checked in under a false name, according to the Nassau County Sheriff’s Office.

Several hours later, the resort guest under that name showed up, the Sheriff’s Office added. Security found Hartman the next day in a room that was under renovation.

Under questioning, the report from the sheriff’s deputy read, Hartman admitted staying in the $300-per-night room and added that “she traveled from Minnesota to Jacksonville on a flight with no boarding pass or airline ticket.”

Jacksonville airport spokesman Michael Stewart said authorities have requested any surveillance images that might help with their investigation.

Delta spokesman Morgan Durrant, whose airline operates between its Minneapolis hub and Jacksonville, said, “We are aware of the reports of the arrest and are looking into the matter.”

Undersheriff George Lueders said his office is working with the TSA and airport police to further investigate her admission about flying into Jacksonville.

Hartman has been accused of trying to stow away on flights many times. Most recently, in August, she allegedly breached security at Mineta San Jose International Airport and took a Southwest Airlines flight to Los Angeles.

She has been caught repeatedly trying to board flights at San Francisco’s international airport without a ticket, but airport staff have thwarted her.

After her arrest in August in California, Hartman told KCBS-TV that “it was clearly wrong on my part, and I certainly do not want to do it again, because I certainly don’t want to do any jail time.”

She told the station that she is a retired secretary and now homeless. Court records show her most recent address as being in San Diego.
