Two people accused of committing a sexual act on an Air Canada plane in January are scheduled to go to trial next year after pleading not guilty to committing an indecent act.

Court records say Jason George Chase, 39, and Alicia Elizabeth Lander, 25, are alleged to have participated in an indecent act in a public place on Jan. 24.

They were arrested by police after arriving at the Halifax Stanfield International Airport on a flight from Toronto.

The accused were not in Dartmouth provincial court on Tuesday but their defence lawyers entered the pleas on their behalf.

The trial has been set for Jan. 21, 2015.

In addition to the indecent act charge, Lander is also charged with causing a disturbance, assaulting a police officer and mischief. Police told CBC News that after Lander was arrested, she was verbally abusive and kicked officers.

Lyle Howe, Lander's lawyer, said his client decided to plead not guilty to those charges as well after receiving disclosure from the Crown.

"We've reviewed the paperwork and we've decided that that's what we were going to enter as our plea," he told reporters.

"Any time somebody is alleged to have committed a criminal offence is a difficult ordeal."
