Air Canada and the Canadian Union of Public Employees, which represents roughly 10,000 flight attendants, reached a mediated tentative agreement early Tuesday, ending a strike that began on 16 August and halted the carrier’s operations. The union told members the walkout was over and that a ratification vote will follow. The four-day work stoppage forced Canada’s largest airline to cancel at least 1,219 domestic and 1,339 international flights, according to aviation data firm Cirium, disrupting the travel plans of an estimated 130,000 passengers a day at the height of the summer season. The Canada Industrial Relations Board had declared the strike unlawful, and federal officials had urged both sides to settle quickly. While full details were not disclosed, union officials said the draft contract guarantees pay for ground duties such as boarding, a key issue in the dispute. Air Canada had previously proposed a 38 percent increase in total compensation over four years, including a 25 percent jump in the first year—an offer the union had called insufficient. Air Canada said it will gradually restart flights beginning Tuesday evening and warned that restoring its normal schedule of about 700 daily services could take seven to ten days. Customers on canceled flights are eligible for refunds or rebooking once operations stabilize.
