Air Canada suspended its operations after more than 10,000 flight attendants went on strike early Saturday following the expiration of a deadline to reach a labor agreement. The strike has disrupted travel for approximately 130,000 passengers daily during the peak summer travel season. Despite a government-backed return-to-work order issued by the labor board, the union representing the flight attendants has refused to comply, prompting Air Canada to delay the resumption of flights initially planned for Sunday. As a result, the airline postponed restarting its operations until Monday evening, leaving travelers worldwide stranded and uncertain about their travel plans.
