Marilyn Hartman, 62, was banned from San Francisco International Airport earlier this year after reportedly making at least three attempts to board without a ticket, but was caught each time before the plane departed.
The San Jose incident on Monday may be the first time Hartman achieved success and made it off the tarmac, but authorities stressed that at no point did she pose a threat to public safety. Instead, officials in San Mateo told a Bay Area news station that her repeated stowaway attempts may just be a sign of loneliness.

An official with the agency told The Times the woman managed to sneak past the initial boarding pass checkpoint when a TSA agent was distracted.
San Jose airport officials said in a statement that its security check processes were not a factor in the breach and that public safety was "never compromised."
After an initial review, the TSA said it has initiated "minor modifications to the layout of the document checking area."
Southwest could face regulatory fines in connection with Monday's incident, a TSA official said.
Hartman was arrested at LAX on suspicion of trespassing and was jailed in lieu of $500 bail, officials said.
