Canadians with Air Canada flights booked this week may want to consider alternative travel options ahead of the looming strike. The union represents 10,000 flight attendants at Air Canada and Air Canada Rouge, which carry approximately 130,000 customers a day who could be affected by a labour disruption. "To provide customers certainty, Air Canada will begin a phased wind-down of most of its operations to be completed over the next three days," reads the Wednesday announcement. The Air Canada Component of CUPE issued its 72-hour strike notice on Wednesday, claiming that the carrier "refused to recognize that flight attendants should be paid for all their time on the job." The carrier says Air Canada Express flights operated by Jazz and PAL Airlines will continue to operate as normal.
