It's still not clear when Air Canada might start flying again as the flight attendants union resolved Monday to push on with a strike but the airline expressed hope that it could get planes off the ground Tuesday.

Air Canada flights will resume on Saturday evening, as a strike by its 10,000 cabin crew came to an end. The Canadian Industrial Relations Board (CIRB) told the airline's staff to return to work and said that an expired collective agreement would be extended until a new one was agreed.

Union leadership said it will continue to support flight attendants on picket lines across the country after the Canada Industrial Relations Board declared the ongoing strike by about 10,000 Air Canada flight attendants unlawful and ordered union leadership to direct members to return to work.
