Flight attendants are demanding better wages and compensation for unpaid work. Currently, Air Canada only compensates flight attendants for the time they are in the air, but its attendants are seeking pay for the work they do before take-off and after landing, too.

A strike by the carrier’s flight attendants could disrupt 130,000 travelers a day, including international fliers. Here’s what to know if your flight is affected.

Mark Nasr, Air Canada's chief operations officer, said that cancellations would go from "several dozens" on Thursday, to some 500 by the end of Friday, to the airline being "completely grounded" at the start of the strike on Saturday, in the absence of a resolution.
