An airline-ticket agent got booked for a round trip to prison yesterday — 2½ years for what even her lawyer called a “harebrained” Ponzi scheme.

Victoria Scardigno, 33, worked for Continental Airlines at Newark-Liberty Airport and swiped 1,750 flight vouchers that she sold to passengers for between $500 and $800.

US District Court Judge John Koeltl could have given Scardigno more than five years in prison.

But he cut Scardigno a break, citing her previously clean record, and gave her just 29 months behind bars.

She also got three years of supervised release when she gets out.

“I would refer to it as a harebrained scheme, a scheme destined to failure,” defense attorney Richard Lind said. “I just don’t see . . . the benefit of a period of incarceration.”

Scardigno tearfully told the judge she’s sorry.

“I am beyond remorseful,” she said. “I understand how immoral I was. I will not put myself in a position like this again.”
