Flights operated by Air Canada’s main line or Rouge would be impacted, and most likely cancelled were flight attendants to go on strike. Air Canada Express and Jazz flights might not be impacted directly, since they are in different agreements, but could be due to the impact of cancelled flights.

Air Canada flight attendants are holding a strike vote on whether to give the union a mandate for job action, with Aug. 16 the earliest date a strike notice could be given.
