An Air Canada flight from Casablanca to Montreal was canceled after a flight attendant had a meltdown over a passenger's request for a blanket, which escalated into a heated confrontation. Video footage shows the attendant yelling, 'You will behave or we will get off!' and threatening to involve the captain and police when passengers expressed solidarity with the requester. The incident prompted the remaining passengers to deplane in support of the affected individual, leading to the flight's cancellation and rebooking of passengers on a different flight with a new crew. Air Canada has since apologized and confirmed that an investigation is underway regarding the staff's conduct, acknowledging that the situation fell short of customer expectations. The airline has also offered compensation to those impacted by the disruption. This incident has sparked discussions about appropriate behavior and de-escalation tactics among flight crew members.
