Air Canada is canceling some flights as the airline winds down service ahead of a looming flight attendants’ strike. The airline says it plans to stop flying on Saturday after its flight attendants’ union served a 72-hour strike notice.

Air Canada said it will start cancelling flights on Thursday ahead of a possible strike by its flight attendants, which the airline said will allow for an orderly shutdown of Canada's largest airline.

Air Canada says it is beginning a "phased wind down" of most of its operations after thousands of flight attendants voted to strike.
