Two women are in custody after a Sunwing flight bound for Cuba was forced to return to Toronto's Pearson International Airport on Wednesday evening.
The airline says the flight had taken off from Toronto at 4:30 p.m. en route to Cuba when it was disrupted by "two unruly female passengers."
Sunwing vice-president Janine Chapman says the passengers had consumed a "significant quantity of their duty free alcohol purchase in the lavatory."
She says they then lit a cigarette, triggering the smoke alarm, and "proceeded to get into a physical altercation with each other and made a threat against the aircraft."
Chapman added in an email to The Canadian Press that the threat was considered non-credible given the condition of the passengers.
NORAD said it scrambled two CF-18 fighter jets based out of Bagotville, Que., to escort Flight 656 back to Toronto.
Peel Region police took the two unidentified women into custody once the aircraft arrived back at Pearson. There was no word on what charges might be laid against them.
Chapman said the flight was scheduled to leave Pearson again at about 11 p.m. with a new flight crew.
