Air Canada has canceled most of its flights over the next few days to prepare for a strike by flight attendants. Some travelers may end up stranded as a result.

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.
