Air Canada's unionized flight attendants walked off the job early on Saturday morning after pay talks with the country's largest carrier stalled, in a move that is expected to disrupt travel plans for more than 100,000 passengers.
The union representing more than 10,000 Air Canada flight attendants confirmed the 72-hour stoppage in a social media post just before 0100 ET (0500 GMT) in the first strike by flight attendants since 1985, Reuters reported.
The airline said on Saturday it had suspended all flights for Air Canada and its budget arm Air Canada Rouge, after cabin crew represented by the Canadian Union of Public Employees (CUPE) went on strike.
"About 130,000 customers will be impacted each day that the strike continues," Air Canada said in a statement.
"Air Canada is strongly advising affected customers not to go to the airport unless they have a confirmed ticket on an airline other than Air Canada or Air Canada Rouge," the airline said.
Flights for regional operators Air Canada Jazz and PAL Airlines would continue to operate.
Attendants are currently paid when the plane is moving and the union is seeking to also be compensated for time spent on the ground between flights and helping passengers board.
Montreal-based Air Canada, which is expected to respond quickly by locking out the workers, had said it anticipated canceling 623 flights by the end of Friday during the busy summer travel season. It expected around 100,000 people would be affected on Friday alone.
Flight attendants will on Saturday picket at major Canadian airports, where passengers were already trying to secure new bookings earlier in the week, as the carrier gradually wound down operations.
Air Canada and Air Canada Rouge normally carry about 130,000 customers a day. Air Canada is also the busiest foreign carrier servicing the US by number of scheduled flights.
While the dispute has generated support from passengers for the flight attendants on social media, Canadian businesses reeling from a trade dispute with the United States urged the federal government to impose binding arbitration on both sides, which would end the strike.
Air Canada has asked Prime Minister Mark Carney's minority Liberal government to order both sides into binding arbitration although CUPE, which represents the attendants, said it opposed the move.
The Canada Labour Code gives Jobs Minister Patty Hajdu the right to ask the country's Industrial Relations Board to impose binding arbitration in the interests of protecting the economy.
Hajdu has repeatedly urged the two sides, which are not bargaining, to return to the table.
The union has said Air Canada offered to compensate flight attendants for some work that is now unpaid but only at 50% of their hourly rate.
The carrier had offered a 38% increase in total compensation for flight attendants over four years, with a 25% raise in the first year, which the union said was insufficient.
