Maygan Sensenberger, 23, was in court in Saskatoon on Friday, after allegedly threatening passengers, swearing, and arguing with her husband, Rod Zimmer, 69.
Court records show the disturbance happened on Air Canada Flight 8597, which originated in Halifax, stopped in Ottawa and then went on to Saskatoon.
"It's our understanding that throughout the flight, there was a verbal argument taking place of a domestic nature," said Alyson Edwards, spokesperson with the Saskatoon Police Service.
According to witnesses, Sensenberger created a large disturbance and it only got worse as the plane neared Saskatoon, Edwards said.
"The suspect in this case had stated to several people that she believed her husband was in medical distress," said Edwards, adding that alcohol may have been a factor.
Officers met the woman when the aircraft landed.
Sensenberger is charged with endangering the safety of the aircraft and causing a disturbance. Court records show police believe she uttered threats against her husband and threatened to take down the plane.
Zimmer, who is a Liberal and represents Manitoba in the Senate, was appointed to the Canadian upper chamber in 2005 by then-prime minister Paul Martin.
No one was injured in the incident and police say the safety of the aircraft was not compromised.
Sensenberger was visibly shaken and tearful in the prisoner's box during her court appearance Friday.
She will be remanded in custody until her second appearance on Monday.
A Facebook page that was started in 2010 called, "Rod Zimmer & Maygan Sensenberger's Wedding Page," says they were married on Aug. 27, 2011.
Pictures apparently taken in the House of Commons show the happy couple looking deeply into each others' eyes while holding one another. Sensenberger shows off her ring in at least one of the photos.
Zimmer was born in Kuroki, Sask., east of Saskatoon, and currently lives in Winnipeg.
His parliamentary biography lists several positions he held before being appointed a senator, including vice president for the festivals for the Pan American Games Society Inc., a member of the board of directors for the Winnipeg Blue Bombers Football Club and a member of the board of the Canadian Paralympic Foundation.
