Air Canada will begin cancelling flights on Thursday due to a potential strike by 10,000 flight attendants represented by the Canadian Union of Public Employees (CUPE). The union issued a 72-hour strike notice after contract negotiations failed, citing disagreements over wages and unpaid work. Air Canada will gradually cancel flights, starting Thursday, with a complete shutdown planned for Saturday. The airline estimates 130,000 daily customers could be affected. Passengers with cancelled flights will receive refunds and alternative travel options will be explored.
