Air Canada has begun cancelling flights ahead of a potential strike by its flight attendants, with plans to cancel up to 500 flights by the end of the week. The airline is bracing for significant travel chaos as negotiations falter, prompting flight attendants to issue a strike notice. With over 10,000 cabin crew members voting overwhelmingly in favor of the strike, the situation escalates as the airline seeks government intervention amid stalled contract talks. Travelers are advised to check their flight status, as many could face disruptions over the weekend. The imminent work stoppage has raised concerns for travelers, particularly during peak seasons.
