Maygan Sensenberger, 23, received a suspended sentence during a court appearance Thursday.
Sensenberger was also accused of uttering threats against her 69-year-old husband, but the Crown withdrew that charge.
Under the terms of her sentence, she must take any counselling required by her probation officer. The Crown prosecutor said that could include addictions counselling, Alcoholics Anonymous meetings or anger management classes.
When she was charged, police alleged Sensenberger said she would slit her husband's throat during the flight.
On Thursday, provincial court Judge Marilyn Gray said she believes much of the disturbance caused on the flight would have been avoided had Sensenberger not been drinking.
Sensenberger's lawyer, Leslie Sullivan, said she didn't agree with the way the story was covered by the media.
"It's that you all have focused on my client and her relationship with her husband and not some of the other issues that arose throughout the case," she said. Outside court, Sensenberger was hugged by several people. Her husband was nearby.
