A woman who, along with her boyfriend, disrupted a Delta Air Lines flight bound for Los Angeles in December, forcing it to return to the Twin Cities, has been sentenced to probation and community service.

Anna C. Koosmann, 37, an Edina native who now lives in Los Angeles, was sentenced in Hennepin County District Court to a year’s probation and ordered to pay $578. She also was ordered to perform 10 days of community service for the mayhem on Dec. 28 aboard the Delta airliner.

The flight left about 6:20 p.m. only to return to Minneapolis-St. Paul International Airport at 7:35 p.m. A passenger who captured some of the episode on video said Koosmann wanted to use the bathroom, but she became agitated after being ordered back to her seat.

Police led Koosmann and Blake Fleisig, 36, of Los Angeles, off the plane to the jeers of fellow passengers. That prompted Fleisig to take a swing at one passenger, said Patrick Whalen, who shot the video and posted it on YouTube.

Applause broke out once the two were gone from the airliner, and the resumed flight reached the gate in Los Angeles about 2¼ hours late.

Koosmann admitted last week to obstructing the legal process, a misdemeanor and had a disorderly conduct misdemeanor count dismissed. If she complies with probation, the obstruction charge will be dropped as well.

The misdemeanor counts against Fleisig were dropped in January.
