Air Canada attendant strike grounds thousands across Canada; PM Mark Carney calls union defiance disappointing

A major disruption hits Air Canada as flight attendants strike. Thousands of passengers face travel chaos. Union leaders defy a back-to-work order. The government intervenes, citing economic concerns. The airline suspends financial forecasts. Negotiations failed over pay and working conditions. The union challenges the government's decision in court. Both sides remain firm, leaving travellers in limbo.
