Kriss pleaded guilty last August, to calling the airport police dispatch center at LAX on August 30, 2007. She was accused of making false claims that Essam Anwar Beshara would use chemicals to hijack an Egypt-bound flight the next day.
Prosecutors say Beshara is a former friend of Kriss, whom she believed was her boyfriend at the time. He was boarding the flight to Egypt to attend his wedding.
Court papers reveal that Kriss, who had previously been arrested for stalking Beshara, told police Beshara would use his family members as hostages on the flight.
Airport police believed the call to be a hoax, but Beshara and his family were barred from boarding the plane.
Prosecutors say, as a result, the Beshara family was forced to purchase same-day tickets, costing them more than $14,000.
U.S. District Court Judge Florence-Marie Cooper said Kriss's "obsessive behavior" towards Beshara was "the result of some sort of mental imbalance" and that normally such conduct demands prison time.
Cooper ordered Kriss to have absolutely no conduct of any kind with Beshara or his family, and said she could face 15 months in federal prison if she violates parole.
Kriss tearfully apologized to the judge for her behavior, and the troubles she caused to the victims, saying she will never repeat her actions.
